One Planet Only Forever at 01:20 AM on 31 March 2022The Climate Shell Game
jan,
Another important consideration is 'history of per capita impacts'. Current day people in a nation often benefit from the harmful ghg impacts of the past by 'the nation or region they were born in or live in'. And that past harm should be attributable to them as something they should make amends for.
Our World in Data Per Capita CO2 Emissions Table presentation provides an excellent way to explore the per capita by nation. Of course, that evaluation misses the identification of harmful high impact regional populations like Alberta inside Canada. And, as mentioned @85, that method of seeking to identify the problem can miss the fact that the real target needs to be the highest impacting people benefiting from fossil fuel use. That can include a very small number of people in a very poor nation with very low per capita impacts. It can also be investors in harmful pursuit of profit activity in a region who do not live in the region.

jan,
I think I see the problem.
You appear to have fallen for the Shell Game claims that Top Total Impacting Nations is the way to identify the major part of the problem.
The problem is undeniably the top 20% impacting people. Comparing 'national totals' is a very incorrect way to look at this issue (And comparing the regional totals within a nation can also miss the key point of the need to target the highest impacting portion of the population - I am very sensitive to this point as I am a low impacting person living in Alberta, Canada, disliking being unfairly identified as a problem because of Alberta's 64 tonne per person annual impacts which are higher than many oil producing nations).
Looking at the TOP20 per capita impacting nations would be the proper way to seek the highest impacting people. But even that misses the problem of the high impacting portion of a lower per capita impacting nation.

@Eclectic #80
This was the base of my hypothesis in early 2021 - copy/paste from document No. 2 mentioned in my last post.
All the emissions defined here are Emissions from Fossil fuels only.
---------------------
2010 Global CO2 fossil fuels emissions: 33 971 Mt CO2 (EDGAR-AR5 model)
In model pathways with no or limited overshoot of 1.5C, global net anthropogenic CO2 emissions decline by about 45% from 2010 levels by 2030 (40 60% interquartile range), reaching net zero around 2050 (2045 2055 interquartile range). .... based on IPCC AR5.
2030 goal = 33 971- 45% (15 287) = 18 684 Mt CO2 in 2030
the value: 15 287 Mt CO2 is slightly over of equivalent of the entire: China + US + India emissions (TOP3 emission providers in the world in 2019)
or
179% of 2019 Total emissions from the rest of the TOP20 countries in the world are responsible for 81% of CO2 emissions. Remember the TOP20 label for all the later considerations in this document.
So looking for solutions in the rest of the 188 countries, which generate only 19% of CO2 emissions, is nice, but it has a very small impact on achieving the goals defined in the IPCC AR5.
2019 Global CO2 emissions: 38 017 Mt CO2, then till 2030 we need to decline the emissions by about 50% from 2019 til 2030 (reach the 2010 target), and reaching net zero around 2050.The annual (linear) declination step must be 1 567 MT CO2 = entire Japan+Turkey. Each year. It's supposed to go down, but on the contrary, it's going up. Every year.
With the existing approach to emissions-reducing, we will achieve only 50% reduction from 2020 to 2050.
This means that we will be outside any safe borders as early as 2037, defined by the IPCC as Pathways with higher overshoot. At the end of 2025, this scenario will either be confirmed or refuted.
In global numbers, we should reach less than 30GTin 2025 if we are to adhere to the IPCC predictions to keep warming up to 1.5C.
(Note from 2022: just thanks to the pandemic we get 35.96Gt in 2020, but in 2021 we were back in increase).
However, this means that the TOP20 countries in the world must reduce their emissions by at least 8GT = 27% of their cumulative value from 2019.
Because the rest of the 188 countries have total CO2 emissions of about 7Gt – so there isn’t a doable plan to ask them for a 100% reduction by 2030 (even for 50%).
Just for your imagination, the 27% decrease from the TOP20 countries:
- it is 71% equivalent of their cumulative Power production emissions
- it is 119% equivalent of their cumulative Industry emissions
- it is 151% equivalent of their cumulative Transport emissions ........................ (Note: as you can see no way for EVs to reach it)
- it is 98% equivalent of their cumulative Transport and Buildings emissions
- it is 125% equivalent of their cumulative Buildings and Others (Agricultural, ...) emissions
Till the end of 2025, we only have 4 years and 7 months remaining. (Note: the document is from 2021)The first bad sign of discomfort will be 34.5Gt at the end of 2025. According to the AR5 report, we need less than 30Gt in 2025 and less than 20Gt in 2030.
I'll be really happy if someone refutes this plan.
Otherwise, it won't be good at all.Pareto principle:
20 (10%) countries are responsible for 81% of CO2 emissions. ...... here we need to try to find major reduction scenarios.

Jan @81 , thank you for your link to No More Good News on Global Warming. As I am time-poor, I have put it on my To Do list, and I hope I will have the opportunity of letting you know when I have read it.
In the meantime, please think of Einstein and Feynman and other great teachers. ~Execute the Alexandrian solution ! Cut through the Gordian Knot of taxonomies and epistemologies ! Penetrate at once to the heart of the pragmatic solution of the fossil fuel CO2 emissions (and maybe their equivalences as well? ).
In particular , please enlighten our fretful readers about the most efficient solutions to AGW, as you have hinted in your statement regarding the intelligent usage of the Pareto Principle ~ where 20% of the effort can produce 80% of the desired result. This is important information, surely, and deserves immediate attention here. What is the 20% you speak of? Can you not give a decent outline of it, per a single paragraph? Please express the heart of the idea (and minor details can be examined later).

I still don't know why you mentioned him (twice), and now I don't care. Your writing style and approach is discouraging people from reading whatever point you are trying to make.

@Eclectic #80
First of all, it is necessary to unify what kind of data we will interpret:
a) or GHG emissions converted to CO2 equivalent = CO2 + other types of gases enter the atmosphere may/may not be related to the combustion of fossil fuels
b) "pure" CO2 emissions from fossil fuels onlyThen B) emissions are a subcategory of the A) emissions.
All of the above emission values come from qualified estimates (some with a more accurate attitude some with how to say ... based on an estimate from the estimates), there is nothing like 100% true in this area. I'm not writing this because of the Climate denier topic, but in research and interpretation, it's really important to understand how those datasets are created. Otherwise, incorrect/inappropriate interpretations may (and often do) occur.
Many people don't know about it and then compare pears to apples.Therefore, it is necessary to create, adhere to and comment on data according to "data taxonomy" = a classification of the data according to the right categories/subcategories, sources, credibility, ...
General Data taxonomy unfortunately very missing. I suggested to the European JRC that I could handle them. Including the facts described by the positive effects on the exchange of data between UN FAO - EDGAR datasets. Including the negative scenarios that exist today and will be maintained unless they change that. As I mentioned above, the European JRC has responded and is consulting the options. On the contrary, the FAO (UN Food and Agriculture Organization) is silent.
The biggest problem with these qualified estimates is the data inconsistency. E.g. the EDGAR model for defining emissions by individual states and regions (Power production, Transport, Building, ...) is still "active" = today's exported data for 2019 do not match the data you exported from the same model in 2021 for the same year 2019. It is very difficult to qualify the shift in YoY emissions because what was true last year is no longer valid today.
A simplified example:
This is similar to achieving 2.5% YoY Product Sales for a Car company in 2019 (calculated in 2020), but if you want to recalculate this in 2021, you will reach 1.9% YoY only. One would say that the 0.6% is a negligible value. At 35Gt of CO2 emissions, this makes a difference of 0.21Gt, which is more than the annual Transport emissions generation from 21 EU27 countries or more than the annual total of 92 countries for the CO2 emissions from fossil fuels. For the average reader, 0.6% means nothing. For a data scientist, this is a data disaster.If you read my simple essay, which is more intended for the average user, you will find the basis of the 80/20 problem explained in a really simple way:

Eclectic at 20:49 PM on 30 March 2022The Climate Shell Game
Jan @79 : thank you for your further contributions.
What I observe in the articles & comments columns of SkS [SkepticalScience] is that there is a very wide range of readers and participants. This can be seen in the threads and "Climate Myths" articles & commentary during the past dozen years or more.
The majority of commenters are (like me) at a basic level of critical thinking & scientific education ~ let us say, at the level of upper highschool to undergraduate university. Yet there are also many others at a very advanced level of education (like you).
Nevertheless, the SkS website must cater for the whole range. And that includes readers who are too time-poor to devote hours per day in the pursuit of climate knowledge and in the acquisition of well-informed opinions in the practicalities of tackling climate & energy. It is this very group [the large majority, like me] who rely upon the helpful summarizations provided by experts [like you].
One of the markers of true expertise, is the ability to give a concise and lucid explanation of important ideas & concepts. We see that ability in great minds such as Einstein and Feynman.
For all these reasons, Jan, I must again ask you to put aside all the fine details which distract ~ and to provide readers wth the pragmatic core of your understanding of the way forward in climate solutions. In particular, please educate us (in concise form) about the [Pareto] 20% of climate-correcting actions we can undertake to fix 80% of the CO2 emissions problem. Your statement about the 20%/80% , in relation to climate, is intriguingly new to me (and doubtless intriguing to many other readers, too).

I'm not a fan of Ivar Giaever (Climate change opinions)
------------------------------------------
@nigelj @Eclectic and others
100% agree - that the communication here is difficult. From any aspects.
If I may suggest you, try to study the documents I have proposed (see a short list below), which will help you understand that I am not taking numbers out of my pocket here, but that there is serious research behind it. I describe the documents through the mutual stories that interact. There is a lot of visualization because the clean text is an outdated form of interpretation.
I repeat, this problem is so complex that it cannot be described by keywords. So if Skeptical Science is really about Science, then we need to get to a state of understanding at least in the basic domains. My documents will help you with that. Subsequently, we can resume the discussion on specific issues. Based on specific sources and data. Not just based on opinions.
I will be happy to explain the basic principles of the energy lifecycle, but - this SkS forum = an offline and technologically outdated system will complicate it. That needs to be said. I admit that I am not a great writer, such as Dr. Greger, who can enchant the masses only through keywords. This, on the other hand, has a negative impact - because it has created a religion in the field of what is now called Nutrition Science. And he doesn't have to prove anything to his audience.If you have the interest to get some deeper answers mentioned here, you can start with this document reading list in the order (pls download them because Academia.edu portal has for preview just low res extracts):
1. GHG emissions problems in a dark box - Part 05 - Population, Land, Food, Emissions and data disaster
In this document, I address the impact of FOOD systems on anthropogenic GHG emissions. I was prompted to analyze several polarizing articles that appeared to be scientific, but they had little in common as is customary with science. It creates such a fake, dare I say, a manipulative area in which the masses are lost because they cannot understand the depth of the problem.
The emission issue associated with Food systems cannot be declared with a single number that has zero significance. The knowledge that we are composed of approximately 7 x 1027 atoms does not alone allow us to compose a functional human body.
Also, being aware that Food systems cause 1/3 of GHG emissions can't help us understand the core of the problem. It's just a number without expressing complex relationships. This problem is complex, and each new interaction confuses the situation even more.2. GHG [CO2] emissions problem in a dark box - 1st part of the Global warming series
The purpose of this analysis and consideration is to offer a clearer report on how the current efforts to reduce GHG are failing This failure is that much bigger because at a mathematical
level it is not possible to secure the promises of individual countries I hope this will help open your eyes I'm afraid people are too contempt with what someone has drawn Now it's time for a cold shower.3. GHG CO2 emissions - Part 01 China Power production, race to zero analysis
Because China is the main indicator of our worldwide race to zero from all the possible points. Chinese Power industry emissions share 12% of Global CO2 emissions (2019), source
by EDGAR . The Second challenge is a statement of president Xi Jinping at the General Debate of the 75th Session of The United Nations General Assembly: “We aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before Source So the challenge is accepted, there is a simple hypothesis:Is it doable to achieve CO2 emissions peak before 2030 and achieve the carbon neutrality before 2060 in China?
The answer is:
“No” for the emission peak before 2030. Technically and mathematically not doable. Even with totally frozen industry.
“No” for the carbon neutrality before 2060. Technically and mathematically not doable. Even when China will freeze its industry for the next 39 years it’s questionable.
The document focuses mainly on the Power Production segment from the CO2 emissions point of view. All the interpretations are again based on publicly available data, including references to them. So everyone can check my interpretations based on free access to data.4. China Power production CO2 emissions issue in single page

swampfoxh at 12:44 PM on 30 March 2022The ‘whys’ beyond the ‘what’ of the severe western U.S. drought
Bill Debuys, in his book, "A Great Aridness" pushes the history of western megadrought back to end of the Last Ice Age (cir 13,000 years ago) and shows a pattern of extreme drought occurring roughly every 1,000 years. I think I remembering his speculating that the Native tribes actually pulled up stakes and left the area altogether, moving to the Mississippi valley. The drought hatched in 1050 apparently persisted until about 1200 CE.

In addition to my comment @76,
The comparison of total impacts, production and power impacts, of ICE vs EV at 150,000 km of vehicle use under-estimates the benefits of EVs if the vehicle is driven further. Many vehicles are driven far further than 150,000 km.

Evan at 11:08 AM on 30 March 2022SkS Analogy 3 - The Greenhouse Effect is Like a Cloudy Night
Charlie_Brown@17, thanks for your heat transfer lesson.
I certainly agree with you that the system must be in equilibrium, not storing nor generating energy.
Regarding what happens at the top of the atmosphere, I'm not sure it is as simple as you state, nor do I want to get into a discussion that may take me over my head. Although I understand geometrically that radiation is emitted uniformly in all directions, in the direction towards space molecular density is lower than in the direction towards Earth. Therefore, radiation directed towards Earth tends to get intercepted more than the radiation that is directed towards space, which has an easier time escaping the atmosphere. This cools the upper atmosphere, because the more CO2 present the more infrared radiation is created and the more heat escapes to space. Therefore, one of the fingerprints of global warming is that the lower atmosphere warms, and the upper atmosphere cools. Read here for a NASA description of this effect.
I am reminded of the sun. Most people know that from the surface of the sun the sunlight takes only a little over 8 minutes to reach Earth. But how many people know that radiation created at the center of the sun takes about 100,000 years to reach the surface of the sun, because of the density of the inner sun. So there is the added complexity of the density of atmosphere's that also affect radiation heat transfer.
And this is all way beyond the intent of the analogy. I appreciate your comments and I will try to sharpen up the comments in the analogy to make sure they do not mislead.

One Planet Only Forever at 09:22 AM on 30 March 2022The Climate Shell Game
jan and others,
The following CBC News item seems to capture the main points about how EVs and grid generation get discussed.
With Nova Scotia's reliance on coal, are electric vehicles the greenest option?
The main points are that even the Nova Scotia grid with a fairly high fossil fuel percentage, and a significant amount of coal, makes EVs a good choice. And it highlights the added reason that the grid will get better quickly.
The following NPR News item ties back to the Shell Game problem, but more precisely to the harmful misleading marketing part of the Shell Game.
Misinformation is derailing renewable energy projects across the United States
The main point in the USA is the ways that harmful promoters of misinformation are delaying the improvement of the electricity generation, delaying he benefits of EVs.
A final point not in either article is that everybody who wants an EV in the next few years will be unable to get one because the production has to ramp up. However, in 10 years time there will be a massive percentage of EVs on the roads everywhere.
A final point is: I find it very disingenuous, almost harmfully biased, to claim that the problem is a developing nation like China (and potentially India would be named next, and maybe the entire continent of Africa) because of some 80-20 made-up rationalization. I agree with targeting the 20% causing 80% of the problem. That would be the 20% of the global population that is the highest personal impacting portion of the population. That would include some people in India and China (likely many among the richest). But it would include a higher percentage of the population of the more advanced nations, because many of the richer people in the more advanced nations failed to reduce how harmful their ways of living and profiting were through the past 30 years, while others were simply developing up to match their examples. The 'legacy harmful leaders by example' are the ones to be targeted for correction. Those legacy richer more harmful people deserve to be targeted ahead of the 'new rich harmful' people who followed the bad examples.
A closing comment. Fossil fuels are a dead-end technology. Future generations cannot continue using a non-renewable technology even if it was not producing other harmful impacts. The ultimate requirement is for policy to be developed and implemented 'everywhere' that will reduce the 'consumerism materialism madness'. The policy needs to be especially focused on correcting and stopping harmful developments even if they are 'cheaper or more profitable or more popular' than more sustainable alternatives. That harmful driving force has created the climate, biodiversity, and other Human Impact threats to the future of humanity. There is no future for that misleading marketing fuelled pursuit of personal desires or competition for impressions of superiority relative to Others.

Charlie_Brown at 09:16 AM on 30 March 2022SkS Analogy 3 - The Greenhouse Effect is Like a Cloudy Night
This is a very good discussion of radiant energy transfer. I have only a couple picky technical distinction quibbles with it. I do appreciate your providing a commonly observed example of radiant energy. Very similar to your example is the function of smudge pots in fruit orchards on cold, clear nights. It is not the heat of the smudge pots that keeps the fruit from freezing.
You say that since “the upper atmosphere is also much colder than the ground, so infrared energy absorbed high in the atmosphere is only weakly re-radiated back to the ground.” All energy that is absorbed high in the atmosphere will be re-radiated, half upwards and half downward. More importantly, as CO2 increases, a smaller amount of IR energy is radiated toward space. This is because more energy that would otherwise escape directly is absorbed and half of it gets re-radiated downward. Without greenhouse gases (GHG), the energy doesn’t get absorbed and all of it goes toward space. Thus the “trapping” occurs by not letting as much energy that exits toward space out the top of the energy system.
Clouds don’t store (accumulate) energy unless the cloud is getting warmer. Cloud droplets either reflect radiant energy or absorb and re-radiate it back toward the Earth. Also, greenhouse gases don’t absorb more radiation than they receive, other than any slight imbalance which is manifested as a temperature change. This brings the temperature of GHGs in equilibrium with the surrounding atmosphere. GHGs re-radiate energy of specific wavelengths back to the ground. As greenhouse gas concentrations increase, more energy is returned to the ground, warming it. To bring the system back into balance with a warmer ground, more IR is emitted by the ground and all wavelengths. Some of it will be at wavelengths that are transparent to IR and will escape to space. All of this is observable using an atmospheric radiation model. The key is the energy balance. Be mindful of the understanding of stored or accumulated energy.
Forgive me for dwelling on esoteric distinctions. I appreciate the opportunity to practice writing about them. I hope that trying to understand them could prompt others to think about them also. -
Eclectic at 09:08 AM on 30 March 2022The Climate Shell Game
Jan , from your posts #72 and #73 , I discern two points where you could provide useful information to readers.
(A) With regard to the Pareto Principle ~ please describe what you believe are the 20% of necessary changes which will produce an 80% reduction in fossil fuels CO2 emissions . . . and that reduction being over a suitably short time span, of course.
(B) Please clarify why you think making small or marginal benefits in emissions reduction [are] not worth attempting. Here, I realize that your clear explanation of point (A) may well provide your explanation of (B) .

nigelj at 07:04 AM on 30 March 2022The Climate Shell Game
Jan
I find your posts good value, but I agree with Eclectic its a bit hard following what you say. It would be helpful if you summarised your views briefly in plain language, and without all the detailed numbers and jargon.
Trying to understand the numbers. Surely you dont need 100% renewables grid for EVs to have lower lifetime emissions than an ICE car? So what is the proportion of renewables you need?
I'm guessing that you would need a grid with at least about 20% renewables and 80% fossils fules for an EV to have lifetime emissions lower than an ICE car. That you would need at least 20% renewables to effectively cancel out the embedded carbon in manufacturing the EV. What would you say?
But its not all about emissions. Personally I will buy either an EV or PHEV in a couple of years parlty for climate reasons but also because of reliability and low running costs.
In an ideal engineering world the numbers of EVS and the grid should be in perfect harmony but the "cat is effectively out of the bag" and people might decide they just want EVs right now, and government's can't really tell auto manufacturers how many EVs to produce. The grid would then have to run to catch up with the EVs.
I do vaguely understand your grid stability concerns when lots of people are suddenly charging cars. Frequency and voltage issues and stuff like that.
But perhaps its all somewhat academic. I mean that in a plausible and likely real world scenario, renewables will expand gradually to hopefully be 100% by 2050 or probably a bit later, and EV's will gradually expand as well in approximate synchronisation with the energy grid. I'm picking about 100% by 2050 or maybe even later. It takes time for auto manufacturers to build new plant and most people find EVs a bit expensive. So the natural course of things will control the potential chaos. China will be an outlier because its not really a free market economy.
Sorry if my points arent too clear. Hopefully you get what I'm saying. -

@ALL
here is a single slide explanation of Trasport emissions core from last year: GHG CO2 - Part 02 - Transport race to zero emissions analysis in a single page; link
Based on the last EDGAR V6 dataset, nothing is dramatically changed in the Transport emissions. Few interpretations for EU27 countries:
- Germany is responsible for 20.45% of emissions. Germany's 2000-2020 emissions growth is -18% (negative), but during the 2010-2019 period it was +6% increase (the 2020 pandemic year we can't take into account)
- 66.62% of emissions are produced from 5 countries (27 total) - Germany, France, Italy, Spain, Poland (sorted by emissions)
- Germany is responsible for the same value of emissions as Italy + Poland together
- Poland is growing +37% in the period 2010-2019
The energy mix in these countries is different (2019):
- Germany 78% from Fossil fuels (zero Nuclear from 2023), high carbon grid
- France 48% from Fossil fuels
- Italy 79% from Fossil fuels (zero Nuclear), high carbon grid
- Spain 72% from Fossil fuels, high carbon grid
- Poland 89% from Fossil fuels (zero Nuclear), high carbon grid
So when these 5 countries responsible for 66.62% of EU27 emissions from transport will migrate during a single day all of their ICE vehicles to EVs and on the same day they will migrate energy production to the low-carbon grid, we will get max. 0.9% savings from the Total world CO2 fossil fuels emissions (35,962.87Mt in 2020); based on EDGAR Dataset v6/2021. The Low-carbon methodology used in the NREL study - was mentioned in my posts.
Which doesn't happen.
Btw: the value from the entire EU27 Transport emissions is 695Mt CO2. In comparison with China's Energy fossil fuels emissions 4794Mt CO2, it's just a 14.5% share.
Saving 10% of China's Energy emissions will bring -479.4Mt CO2, which is 69% of the Total Transport EU27 Emissions = or ZERO Transport emissions in Germany, France, Italy, Spain, Poland and the Netherlands. China grows YoY 2%.
Think about it, if you still think that the uncontrolled exchange of ICEs to EVs is a good idea for reducing Climate change.
That's why I prefer to set a strategy for eliminating emissions through the Pareto principle - look for 20% of sources that will solve 80% of the problems.
However, from some answers here at SkS site, I feel that shooting into the dark aka 80% of the sources, which will solve only less than 20% of the problems, is the only thing I learned here.
No one has invented anything good through chaos yet.

For the benefit of the casual reader, would you please be so kind as to condense your overall message into a single paragraph containing the main point (or two) which you wish to present & educate us with. Some of what you have said is self-evident and is not really in dispute; some is already widely known; and some is not very pertinent to this thread.

@Philippe Chantreau #67
this is my response continued from #69
Section 6 ---------------
Your opinion:
Hall and Lutsey found in 2018 that in all studied European countries, EVs lifecycle emissions over 150,000km were less than ICE, except perhaps in Germany.
Back to the study wording:
As a result of the high efficiency of electric motors and the ability to generate electricity from low-carbon sources, electric cars typically have lower emissions in the use phase compared to similar internal combustion engine vehicles.
They use the term “low-carbon sources” based on their own research: INTEGRATING ELECTRIC VEHICLES WITHIN U.S. AND EUROPEAN EFFICIENCY REGULATIONS (Lutsey, 2017); link. I found there some discrepancies:
a) there is no available term like “low-carbon sources” or “low-carbon”
b) just the “average European grid” or country-specific grid values (Netherlands, Germany, UK, France, Norway)
If I'm referring to something, I should follow the wording.
However, the “low-carbon sources” term was used first time in the NREL study based on a previous study (Brinkman, 2015), which was mentioned by me here #40: Emissions Associated with Electric Vehicle Charging: Impact of Electricity Generation Mix, Charging Infrastructure Availability, and Vehicle Type (McLaren, 2016); link
https://afdc.energy.gov/files/u/publication/ev_emissions_impact.pdf
where the Daily profile of the low-carbon grid (sources) is based on:
- 97% from ZERO Emissions Fuels
- 3% from the Natural Gas
- 0% from the Coal.
In a timeline, it fits, because in 2016 the NREL study was issued and in 2018 they used the term “low-carbon sources” in the study by Hall and Lutsey, 2018.
So yes, I must agree with the study (Hall and Lutsey, 2018), that:As a result of the high efficiency of electric motors and the ability to generate electricity from low-carbon sources, electric cars typically have lower emissions in the use phase compared to similar internal combustion engine vehicles.
Anyway, the study (Lutsey, 2017) compares the mentioned countries - Netherlands, Germany, UK, France, Norway. And this comparison confirmed my analysis and conclusion that we need to compare apples to apples - energy mix by country and not by continents and never by the single global number. See page 7, Figure 4. Electric and conventional vehicle test-cycle and upstream fuel-cycle emissions in Europe …. Where France and Norway have they have fundamentally different values of CO2 emissions (g/km) for EVs (up to 4-5x less than the Netherlands or Germany or UK). Reason:
Electric vehicles have particularly low CO2 emissions in France and Norway due to the high share of nuclear power in France and hydropower in Norway.This is another example of why we can’t use a single emission number as a useful strategy.
Section 7 ---------------
Your opinion:One could say that just the benefit of cutting on particulates would be enough to give EVs an advantage if CO2 life-cycle emissions are comparable. One could also, as was done earlier, argue that waiting until the generation mix is more favorable is counterproductive in the perspective of a large scale transition. As the generation mix improves, the CO2 equivalent/km of a given EV will decrease over the lifetime of the vehicle.
You need to consider that electricity for 100% transition from ICEs to EVs needs to be produced – it doesn’t exist now.Then you need to calculate complex variables:
- you must create a plant to achieve Carbon Neutral till 2050. I have never seen a complex worldwide plan based on UN IPCC outcomes.
- you must calculate the common energy consumption growth in each country (w/o EVs impact). This will mean that you will need to replace much more energy by 2050 than we produce today. And China is in this area mandatory variable again.
- you must calculate fossil fuels energy production YoY growth in fundamental countries, i.e. China. What will make a heavy impact on your Carbon Neutral calculations.
- you must calculate the energy production for EVs in each country. This energy doesn’t exist now. Note – not just for the passenger cars.
- You must calculate energy production for the transition of combustion energy sources (biomass) to clean energy sources – this energy doesn’t exist now also.
- You must calculate that Climate change has an impact on the possibility to keep efficiency or sustainability for some RES. Then you need to plan exactly what kind of RES you will use where. You can’t do it without Nuke.
- You must calculate that this planet has limited sources for croplands and the population will grow to huge numbers (where).
To be sure – biomass has so negative impact on emissions than fossil fuels.Section 8 ---------------
Your opinion:In China, just the benefits of cutting particulates emissions from numerous discrete sources close to people (like cars) is certainly enough to argue in favor of EVs.
My point:
China is the High-carbon electricity producer - according to the mentioned NREL study. Is there exact evidence that China's electricity production is falling with emissions? Unfortunately, I did not find one from the official Chinese Energy Portal. If I'm wrong, I have no problem admitting it. -

@Philippe Chantreau #67
I will divide the answers to your post #67 into several logical sections to make them clear.
Section 1 ---------------
Your opinion:I'm not sure I'm sold on the "driving is regional" argument. In Europe, one can go from the UK to France, Belgium, Netherlands and Germany in one day of driving, although rail would be a better option.
My point:
Sure, you are right in this premise. However, from a scientific point of view, we must look at the following aspects:
a) What is the mileage ratio in the region defined by the country vs abroad ratio
b) For the individual car segments (passenger cars, local trucks, foreign trucks, agricultural vehicles,…). This can give us a much better view of the basis of this hypothesis (chaotic or controlled migration from ICEs to EVs). The mentioned Dutch study focused only on passenger cars. I quote: "The car class we focus on is the compact 5-seater. It includes the Volkswagen Golf, Ford Focus, Renault Megane, Toyota Corolla and Opel Astra. We compare EV configurations to a regular petrol car, diesel car, parallel hybrid car and SHEV."
c) What is the current energy mix that is created in each country (starting point of the research). This was taken into account in the Dutch study. It should be borne in mind that some countries are heavily dependent on electricity imports from neighbouring countries. For example, the Netherlands had imports at 18% of their consumption in 2020 (19.8 from 111 TWh); link Then you need consider the import Power sources also.
For a quick look at the energy mix in individual EU countries, you can see this link. However, this source uses older data from 2018. Or in detail on Eurostat datasets – more precise.d) What is the plan of individual countries in terms of the energy mix in the distribution network in short-term and long-term planning. This was taken into account in that Dutch study very lightly. And as I wrote today's reality in the Netherlands is entirely different - so the scenarios from that study are out of real range. The benefit of such a study is therefore only in the idea, not in its conclusions.
e) What is the state of individual parts of the energy distribution grid region (Transmission lines capacity, distribution lines, terminal stations, transformers capacity - their age and efficiency impacts). This is essential for defining sustainable transition ICEs to EVs. It is not possible to connect sources of such huge quantities anywhere. The physically impossible without affecting the sustainability of the Power grid.Every single mentioned information (from a to e) is publicly available. But I understand that it is easier for someone to create an "average value" of emissions in Europe than to do fundamental research. It is impossible to say that every EV can be charged because an electrical outlet is enough what you need for it. Without analyzing the inputs mentioned above, this mistake is just a mistake and a chaotic approach.
Section 2 ---------------
Your opinion:
The European Union is a very integrated region, where the electrical grid is essentially one system.
Partly answered above:
- Yes, in terms of network quality regulation. I mentioned in # 33 that the EU was 1/2021 near Blackout due to the power supply failure that is suspected of having originated in Romania disrupting the Continental Europe Synchronous Area. Its frequency dropped to 48.75 Hz (target frequency 50Hz), which caused the South-East area to be separated from the rest of the grid.
- Not, because of the fundamentally different inputs of energy production sources at the country level. I mentioned the example in # 34 or in Section 1.
These parameters cannot be separated and generalized. Therefore, this is not a scientific approach to analyzing and interpreting a hypothesis.Section 3 ---------------
Your opinion:
Establishing standards can not be done only at the scale of one small country like the Netherlands, and the overall benefit is what must be considered.
My point:
100% agree, but the “overall benefit is what must be considered” must be qualified strictly regionally without the usage of “strange” average fixed value per continent. The UC Berkeley science philosopher Thomas Kuhn, in The Structure of Scientific Revolutions (1962), observed that scientists frequently tend to ignore data that does not fit into their scientific paradigm.Section 4 ---------------
Your opinion:Furthermore, the one thing that really matters is global emissions; whether we like it or not, that is what makes the radiative forcing.
100% agreeSection 5 ---------------
Your opinion:Any way to lower global emissions is beneficial.
My point:
From a prime perspective, I agree with you.
However, if we really want to heal this planet and we really want to achieve the conditions for a permanent reduction in emissions, then we cannot just generalize it and not deal with it chaotically at all because it suits us in the discussion. If we pretend that there is only one way to reduce emissions and ignore others, we can reach the blind alley stage.
If you are interested, study my latest analysis carefully: GHG emissions problems in a dark box - Part 05 - Population, Land, Food, Emissions and data disaster
link (btw reviewed by 3 independent persons at Academia.edu)Maybe some context will open up your eye. Because the problem is complex. I looked at the dependencies of population growth, emissions generation, the food systems, the agriculture sector and linked them into one story. The biggest problem I am constantly discovering is the inconsistency of the data used for the research. For example, I am in direct touch with the European Joint Research Centre, which manages the EDGAR Emissions Databases for the UN. We have concluded that they will adjust their datasets so that divergent and even inappropriate interpretations of their emissions data do not arise. Unfortunately, FAO (Food and Agriculture Organization of the UN) and their FAOSTAT do not communicate at all. There is a heavy data mess.
I don't force anyone to follow my thoughts.
I'll finish the rest of your post later. -

when you will read all my posts in this thread you will understand my point to Ivar Giaever.
Especially in a portal which is about the science, as appears SkS also it's necessary read entire thread. Science is (should be) about a complex information gathering. Otherwise, one gets into a situation where he evaluates only part of the available information, which must lead to a wrong conclusion.

@michael sweet #61
I will continue to use the facts only:
1. in my post #40 you can read:
Vehicles operation is not global but regional. It follows that we cannot use global emissions from cars as a tool to calculate emission reductions with the introduction of EVs, but strictly regional, per country. It will be mathematically correct (the global data approach), but you will not be able to put it into practice.
What was the purpose of my discussion regarding the largest producer of GHG emissions with the largest EVs market in this world (+50%) with +70% of Power production from fossil fuels (and it grows). I don't like Global Math Averages. In principle, the arithmetic mean is the least accurate indicator of reality. I presented you with the NREL study, which may not fit into your concept, but it cannot suit everyone. However, if the comprehensive study by The National Renewable Energy Laboratory is not enough for you, it is difficult to look for anything more accurate.
So we can check your mentioned study about the EVs better emissions for Global strategy:
2. Your study (Vliet et all, 2011) mentioned in #61 contains a different statement (page 7):
"We find that EVs charged using electricity from coal do not have significantly different GHG emissions from driving in regular cars."
and as you wrote here:
"We find that EVs charged using [100%] electricity from coal do not have significantly different GHG emissions from driving in regular cars."
the value [100%] was defined on the basis of your own interpretation?
link to the study to confirmation of the mentioned wording (page 7)
following the study you need to take into account:
- study is from 2010 (published)
- it is about the Netherland's specific conditions only, you can't take it as the holy grail for each country
- also specific conditions for Power production must be taken into account - the NGCC technology is more predominant in this country = lower emission factor than coal-fired plants (you can see the differences in Table 4.: Electricity generation capacity in the Netherlands)
- you will find there also an increase in the pulverised coal-fired plants for the 2015-2030 period (Table 4)
- and finally - Summary and conclusions (Page 11) ... read carefully:
WTW GHG emissions from electric driving depend most on the fuel type (coal or natural gas) used in the generation of electricity
for charging, and range between 0 g km−1 (using renewables) and 155gkm−1 (using electricity from an old coal-based plant). Based
on the generation capacity projected for the Netherlands in 2015, additional electricity for EV charging would largely be generated
using natural gas, emitting 35–77 g CO2eq km−1. In the Dutch context, emissions vary little with charging patterns, and are unlikely
to change much before 2030.And here is a summary from the IEA report 2020:
In 2018, TPES came from natural gas (42%), oil (37%), coal (11%), biofuels and waste (5%), and small shares from nuclear, wind, solar, hydropower and geothermal. The Netherlands is still one of the largest gas producers in Europe; however, domestic gas supply and gas exports are rapidly declining as production from Groningen is being phased out. Domestic oil supply is small, especially in comparison to the large oil demand. All coal is imported and is used primarily for electricity generation and steel production. The electricity supply is also heavily reliant on fossil fuels. In 2018, electricity generation came primarily from gas (52%) and coal (27%).
it means that there was no such significant coal damping as the study mentioned for 2015 = 55%; it's actually less. And even worse for 2021:
The current energy mix in the Netherlands is natural gas (38%), oil (35%), coal (11%), biofuels and waste (5%), and 11% from nuclear, wind, solar, hydropower and geothermal.
Following reality, the mentioned study is out of a doable plan. I like data and I would like to listen more than personal attacks, rather more deep-dive information from my base education in Energy engineering. I'm the proud owner of a small PVe and Solar water heating, so you really don't have to swear at my fossil fuels lobby. I understand energy - from its production, distribution to consumption.
That's why I'm researching anything related to emissions. Not everyone will like this option - but I'm not a friend of extreme solutions or chaos.
Finally, I'm sending a link to one peer-reviewed study from The Nature - A plant-by-plant strategy for high-ambition coal power phaseout in China. link
If you will find at least 3 fatal mistakes that should not appear in The Nature or any peer-reviewed studies, you have passed the Energy engineering exam. Otherwise, we can no longer talk about Energy engineering from the position where you want to be a professor.
I judge people by what they write about and how they write. I don't care what their education is. And I don't care if the document was peer-reviewed because:
- Energy engineering is my native domain
- We have scientists like Ivar Giaever and similar creators here
- you can choose peer-review as a service from your defined contacts, even in reputable journals.Each of my documents contains data only from scientific sources and/or national sources from which I drew (defined). I don't like bending data. I do not have time for this.

Philippe Chantreau at 02:50 AM on 28 March 2022The Climate Shell Game
I don't understand what Jan is talking about at 54. The problem of how the electricity is generated is such a basic consideration that it has been studied enough to draw conclusions. Multiple studies have shown that the life cycle carbon footprint of EVs is lower than that of ICEs even if they are charged with electricity produced with coal. The battery production process is carbon intensive but that is compensated by the superior efficiency over the lifetime of the car. In pure mpg equivalent over only road use, it more than compensates, even with FF produced electricity.
It takes only 2 years on average for the balance to tilt in favor of EVs. Location and driving habits make it vary. However, when comparing EVs to ICE, it is always possible to reach a mileage where the whole vehicle life carbon emissions become lower for the EV and it is always a realistic number of miles. It just takes more miles when using electricity that has a lot of fossil fuel in the production mix and batteries made in Asia.
CarbonBrief has looked at this in details:
https://www.carbonbrief.org/factcheck-how-electric-vehicles-help-to-tackle-climate-change
Unfortunately, a vehicle is a big purchase. I already have a hybrid that I bought only a few years ago so no EV for me in the near future. Would help also if they became a little less expensive...

michael sweet at 23:57 PM on 27 March 2022The Climate Shell Game
Eric @58,
The articles you link at 58 are discouraging. This article from Carbon Brief, from Sept 2021, titled "How World's coal-powered pipeline has shrunk by three-quarters" since 2015 offers me more hope. The data is similar to the data in your articles but is looked at from a different angle. I see two primary issues with coal plants:
- Fossil interests have tremendous political power.
- It takes 10-15 years to plan and build a large fossil fuel plant.
We all need to work hard to overcome the political power of fossil fuel interests. The market will eventually build out a lot of renewable energy since it is cheaper, but the power of fossil fuel iterests can delay that for a long time.
All the coal plants being built world wide were planned before renewable energy was the cheapest power. The article I cited indicates that many coal power plants are being cancelled since they are no longer economic. It takes the market a lont time to reset completely now that renewable energy is cheapest. The political power of fossil fuels slows down the transition.
Statements upthread like "we will know where to target policies and programs ($$$) to help leapfrog the cheap coal electricity phase" are simply incorrect. Coal electricity costs more than renewable energy. Less developed countries would be better off going straight to renewable than to build out expensive coal plants now. Even if coal were cheaper today, in a few years developed countries will institute carbon fees on imports that will make coal power even more expensive.
It is often hard to be optimistic when politicians respond so slowly. I take hope from the fact that 10 years ago politicians were not even talking about trying to reduce carbon emissions in most countries. Hopefully the turnaround will be soon enough to avoid the worst consequences.
In many poor locations people are purchasing small off grid PV to charge phones, power lights, run refrigerators and other domestic uses. I saw a picture of solar panels that powered a water pump to irrigate opium poppies in Afganistan. This is chepaer than large central generators with long transmission ines, and the transmission lines cannot be cut by war.

Jan@54
I am sorry, I thought that you had done your homework and that I did not have to do your work for you.
The debate about wether it is worthwhile to drive an electric car using power from coal power stations was resolved over 10 years ago in the peer reviewed literature. Newbees who try to do their own calculations simply are wrong.
This peer reviewed paper published in 2011 states:
'We find that EVs charged using [100%] electricity from coal do not have significantly different GHG emissions from driving in regular cars"
Since the efficiency of electric cars has improved since 2011, it is now more efficient from a release of CO2 standpoint to drive an electric car than using an ICE car, even if 100% of the electricity comes from coal. In China, since 30% of the energy is renewable, it obviously is better to drive electric cars. Evan, using at least 50% wind energy, is way better than an ICE car. You are simply uninformed. I do not like being lectured to by people who do not know what they are talking about. I note that you have cited exactly zero peer reviewed papers in your posts here at Skeptical Science while I have cited papers to support my position.
Since electric cars release less CO2 no matter how the electricity is generated, it is best for everyone everywhere to try to purchase an electric car. Waiting until more renewable electricity is being generated results in more CO2 being emitted. Many other reasons also result in the conclusion that it is best to buy an electric car as soon as possible.
Simply looking at the efficiencies I cited in my previous post it can be concluded that it is more carbon efficient to drive an electric car powered by coal electricity than to drive an ICE car. The fact that ICE cars are less than 20% efficient in converting the energy in the gasoline into kinetic energy is the critical factor. Electric cars are about 90% efficient at converting electricity into kinetic energy. I can provide the calculations for you if you want to see them.
In the future as much transportation as possible needs to be converted to electric because electric motors are so much more efficient than ICE motors.
Your claim that we should wait to purchase electric cars until more renewable energy is being generated is simply fossil propaganda. The more electric cars there are the less demand for gasoline there will be.

Haiburton42 at 19:34 PM on 27 March 2022SkS Analogy 3 - The Greenhouse Effect is Like a Cloudy Night
I wrote this in my climate change dream journal at 12:24 am Ogden Utah Time. Light pollution makes it hard to see the stars and I thought the less stars the easier is to make a connect the dots picture — the clouds are the peaceful alternative — and I thought what about a sky polluted no stars shown through and I couldn't make a connect the dot picture that would be a very sad time for me. And a very sad world.
So, I think that when an entire town decides not to drive a car for a week in a row and the stars get brighter and we all go for a walk it can be a very good thing.
And now I'm promoting Take Back the Night brought to us by the Women's Center at WSU because ever since they helped me when I needed it I made a vow to take back the night whenever I can until we no longer have to.
But have I just been off-topic, political or ad hominem in my rhetoric?

Its intriguing reading a thread of comments like this. Because reading them in their entirety its obvious dudo39 is just highjacking the thread to push an agenda. The article was obviously using clouds at night an an analogy only, and said quite clearly "Although the greenhouse effect is active 24/7, it is most apparent at night, " but dudo39 still rambles on @1 about the article not addressing clouds during the day and then the rest of the comments posted drift on from that, and the main issue gets forgotten.

The poor are building out renewable energy in many locations. Why build a coal generator when renewable energy is much cheaper? Why build out central facilities wheen distributed generation (like PV) is much cheaper? You guys need to read the literature and give up on the fossil fuel propaganda.
I assume you mean undeveloped countries? Or people who are actually poor? Coal is being built out because, apparently, it's been easier to get the financing for them from China:
Perceptions of coal for baseload reliability and low cost seem to be the driving factors, but biased by the availability of financing for coal.
I looked through the Connelly link you provided, but that solution was for wealthy Europe. Then clicked from that page to Jacobsen: Matching demand with supply at low cost in 139 countries among 20 world regions with 100% intermittent wind, water, and sunlight (WWS) for all purposes
Seems like that would speak to your claim which I quoted above. Haiti is poor and would have less than 10 cents average electric cost with 65% solar PV (nameplate, table 2). Table 3 shows Haiti with a mainly flexible load (my point earlier). Seems practical and fairly reasonably priced. But "much cheaper"? I don't see that.
Please note I am not promoting coal, just stating the facts of where coal is headed (e.g. as shown by endcoal.org).

David-acct @4,
Here is a Follow-up regarding your unjustified attack on NPR reporting:
The following Nature article "Wuhan market was epicentre of pandemic’s start, studies suggest" appears to rather conclusively prove that you have allowed yourself to be misled about the certainty that COVID-19 came from a lab ... perhaps because of a penchant for the reporting by sources like Fox News. And that bias may apply to other beliefs you have developed a liking for. You really should investigate if your developed bias, everyone has bias and can learn to change it, is causing you to be harmfully misled.
That Nature report has been referred to in NPR reports, including this one "How the false Russian biolab story came to circulate among the U.S. far right"

One Planet Only Forever at 08:46 AM on 25 March 2022The Climate Shell Game
Evan @55,
All things considered, burning gasoline from the oil sands is indeed potentially worse then using Minnesota's electricity to power a car.
One big harm, hidden from many people by the Shell Game, is that upgrading heavy crude (like Alberta's Western Canada Select) produces a by-product called 'coke'. Coke is like a very crappy coal (very high ghg emissions for the heat units obtained, and other crappy emissions from burning the stuff). Some places are OK with dirtier cheaper stuff to burn. They will burn Coke. It has been burned at oil sands operations in Alberta. But, to reduce emission in Alberta, the materials are often now exported as heavy crude (Western Canada Select) which exports the impacts of upgrading, including coke, to the importing nation. And the upgrading facilities in the USA producing the gasoline for Minnesota likely export the coke they produce to be burned somewhere else in the world (so the coke is not counted as a USA waste or ghg impact).
The more you know the more there is to dislike about extracting and burning up the oil sands stuff, and other heavy oils, and coal (and sour natural gas - note that WCS is also a very sour crude - lots of sulphur). Those all really should be the first fossil fuels terminated no matter how many investors lose perceived wealth because 'their assets ended up stranded - unusable'.
Note that the Shell Game includes Alberta Oil Sands promoters claiming it is More Ethical Oil (amusing note Shell sold its oil sands assets).

Evan at 07:49 AM on 25 March 2022The Climate Shell Game
jan@54 another reason I bought an EV. In Minnesota about 90% of our gasoline comes from tar-sands oil. That alone drove me to want to minimize my use of gasoline. IMO, just about anything is better than burning tar-sands oil.
One thing you should consider is that if you want to buy an EV today, you might end up waiting a long time because of supply-chain issues. This is the reality of how long it may take to switch from ICE's to EV's. Even if EV's only operate at break-even GHG emissions in some places because of high usage of fossil fuels, it is worthwhile to start switching manufacturing towards EV's, because the transition will likely take a very long time, given real-world distribution factors.

The car's energy conversion efficiency is one thing; electricity consumption per 1km is the second point. You have to recharge the consumed energy somewhere. And 70 kWh of electricity will always be only 70kWh of electricity, no matter what source you use for recharging. This has nothing to do with energy conversion efficiency while driving in a car. This is the energy (not the capacity) you need to return to the battery. You need also calculate another big impact - batte charging is a Power factor and dirting of the power grid. When you don't understand this basic energy principle, then I'm here by mistake.
When you got the arguments and accused me of fossil fuels propaganda, neither of us understood anything. Nice. -

Evan @48,
Agreed that it is not helpful if the presentation gets too complicated or triggers unjustified reactions.
Another way to address the marketing problem is to describe how it affects every aspect of the diagram (competition game/system) without presenting it as part of the image.
Marketing is about raising awareness and trying to influence what people think about things. Marketing is helpful when it raises awareness and fully informs regarding the awareness being raised. It can be especially helpful when it does that regarding Harm Being Done. But marketing almost never gets done that way because the pursuit of reward and benefit (popularity and profit) powerfully motivates what is done.
That pursuit of reward limits what is Investigated.
- It can keep scientists from looking into the potential harm of developed activities, especially activities that are popular and profitable (because who is going to fund or reward the investigation into the potential need to limit, change or stop popular and profitable activities).
- It can tempt scientists into focusing on research that appears to have the potential to be profitable or popular, because that is more likely to be funded and be rewarded with patents.
- It certainly discourages consumers from investigating if what they are tempted to desire is harmful.
- Engineers have a fairly powerful motivation to limit harm done. But even they can be tempted to participate in developing more harmful results due to the potential for more reward to be obtained that way (or get less reward if they won't play the 'behind the curtain' game that way). And some of them push for 'lower minimum standards', or push to not have standards, because that gives them cover/excuses for participating in producing riskier more harmful results (what they did did not contravene any established requirements - that they were aware of).
Undeniably, the potentially harmful marketing angles of the Industry (pursuers of profit) and Political (pursuers of popularity) players are the most dangerous drivers/motivators of the game/system. And the most dangerous condition is when there is no clear separation of Industry from Government.

Jan @38.
I was wanting to know your academic qualifications to see if you had any relevant to the issues. I'm reluctant to commit time to reading very long articles by people if they have no relevant qualifications at tertiary level. Your engineering degree is definitely very relevant. I believe that a person with an engineering degree could definitely do "science". However calling yourself a scientist could cause confusion and I think you are unwise doing that, fwiw. And I see no need for you to do so.
----------------------------------------
Jan @40, ok we seem to be roughly in agreement, and I get your point about China: They are actually expanding their EV fleet much faster than its expanding renewables which is out of step. However China is non typical with its autocratic government having huge control over EV production. However there are other reasons they are pushing EVs really hard, namely to reduce high levels of particulate and nitrous oxides air pollution in their cities.
Yes the data speaks loudly. I had a friend who always said when arguing about contentious issues, and opining on them, always go back and look at what the basic data says. Regardless of the issue and field of enquiry.

Jan,
I think you have the incorrect assumptions behind many of your calculations. This results in your conclusions being in error. In general, whenever I see someone relying on their own calculations instead of published calculations I figure their conclusions are incorrect. I see very little peer reviewed data in your posts.
For example, many published studies describe how to get 100% renewable energy. See this description of Connelly et al 2021 for a starter. I note that you have no problem with "baseload" power sources that require emergency back up power every day to provide peak power but you are concerned that renewable energy might have problems providing peak power. Why is it OK for "baseload" sources to require back up but not renewables? Most of the pumped hydro storage in the USA was built to store power from nuclear power plants at night to use for peak power during the day. Plans like Connelly et al describe how to provide 100% renewable energy. You are wrong to suggest it cannnot be done. Providing 80% renewable energy using existing fossil gas peaker plants as storage is easy and cheaper than fossil power.
Your anaylsis of EV cars seems to me to be completely off. Even if the grid is 100% coal there are benefits from EV. You do not consider that baseload coal power plants are about 40-45% efficient at generating electricity form the heat of the coal. Gas combined cycle plants are over 60% efficient. EV cars are about 90% efficient in using electricity. By contrast, internal combustion cars are only about 20% efficient at using the energy in the oil they burn. When you consider the comparable emissions of carbon dioxide, an EV with electricity from a 100% coal electrical system releases comparable carbon to internal combustion engines. Since the electricity for Evan is over 50% from wind, his EV releases much less CO2 than a comparable ICE car.
According to Our World in Data China gets about 30% of its electricity from renewable sources. It seems to me that when you consider the efficiency of EV cars compared to internal combustion cars the EV's release less CO2 than ICE. Since almost all coal systems use gas for peak power the release of CO2 is even less from EV cars than ICE cars. My brother has solar panels on his roof that recharge his EV car. How much CO2 does his car release?
This peer reviewed paper says that the best thing to do for the next ten years is to build out renewable energy sources as fast as possible and switch to EV's at the same time. If we wait on EV's until we have more renewable energy we will not be able to switch fast enough from ICE's. Your argument that we should wait for more renewable energy to be built is completely incorrect. Please cite a peer reviewed paper that suppports your wild claims. I think your calculations are incorrect as described above.
I note that the people engaging in this conversation are citing their own calculations and not peer reviewed documents. I see many claims that I think have been demonstrated as false in the peer reviewed papers I have read. It seems to me that many of the claims made here are simly fossil propaganda against renewable energy. I want to remind posters that this is supposed to be a science based site. You must support your claims with peer reviewed data.
The poor are building out renewable energy in many locations. Why build a coal generator when renewable energy is much cheaper? Why build out central facilities wheen distributed generation (like PV) is much cheaper? You guys need to read the literature and give up on the fossil fuel propaganda.

OPOF@46 and 47. Very interesting example. It's easy to market these feel-good stories, because it's what people want to hear. Thanks for sharing yet another concrete example of the Shell Game.
-
Evan at 05:32 AM on 25 March 2022The Climate Shell Game
OPOF @45 Yes, this chain is not complete, but hopefully it conveys the idea without getting too complicated. The inclusion of government might conjure up images of corruption and the like, but every well-functioning society relies on some form of governance to set policies, standards, etc.
Marketing is somewhat implicityly in the industrial segment, because they are the ones manufacturing and selling the products. I'll try to weave in your ideas, but am afraid that the complexity will grow.
There's that growth problem again. :-)

One Planet Only Forever at 05:11 AM on 25 March 2022The Climate Shell Game
I missed an important aspect of the Shell Game example I shared @46.
I am not able to find the total power demand for the Server Farm. It appears that it may be higher than the 400 MW contract for power from the new Solar Farm. And that power demand will be 24-7, not just when the sun shines or the wind blows. So there may even need to be added non-renewable power in Alberta to meet the added power demand for this "new improvement in Alberta".
And the Shell Game sales pitches continue with the glowing presentation by Calgary Economic Development that also mentions all the 'homes Amazon will supposedly be powering with renewable power'.

One Planet Only Forever at 04:25 AM on 25 March 2022The Climate Shell Game
Here is an Alberta Example of the Shell Game.
The largest Solar Farm in Canada is now being built in Alberta. Read the following article about it, and note the statements regarding the 'number of homes it would power'.
CTV News - Canada's largest solar project under construction in Vulcan County
Now read the following article from a different news source published on the same day.
Global News - Southern Alberta firm signs massive solar power deal with tech giant Amazon
Note how the second article tells about the the 'new benefit for Alberta of the Amazon server farm' that is going to consume almost all the power from the new solar farm.
What happened is an added energy demand in Alberta that fully consumes a renewable energy generating facility. Essentially, no improvement. But lots for Albertans, and Others, to be pleased about.

Evan @35,
A suggestion related to my comments @33 and @37 that relates to both the Consumer and Science Disconnect.
The image under Science Disconnect should be expanded to indicate “marketing” (pursuing popularity and profit) behind the curtain and connected to Industry and Politics.
And it would be helpful to have a way to represent “Helpful Governing: The pursuit of learning about the harm of what is developed and effort to limit harm done”. That feature has different values in front of and behind the curtain.
- In front of the curtain there is some interest in self-governing in pursuit of learning to limit harm done, but it is not the ‘governing’ interest.
- Behind the curtain there is a powerful ‘anti-interest’ including attempts to block investigations into potential harms. That drives the development of misleading marketing to cover-up or excuse the harm that cannot be kept hidden. And that marketing over-promotes potential benefits, promotes harmful misunderstanding, and encourages people to be dismissive of the harm or risk of harm (because the benefit has to be worth it).
It would also be helpful to present an "External Influence" - Governing what is going on by pursuing learning and education about what is harmful and implementing policy and laws to limit harm done through education, regulation, restriction and legal penalty.
External Helpful Governing to limit harm done, and change the developed system, is the Key Requirement. Expecting the pursuit of more benefits and higher status to be Self-Governed to limit harm done is obviously absurd. Without external governing effectively limiting harm done the "Science (learning) - Consumer (pursuit of benefit)" system will produce an endless stream of harmful “popular and profitable results”. It will also produce a bunch of harmful results that fail to be the most popular and profitable, but still get to compete in the market. And less harmful developments will have a competitive disadvantage because they will be "less rewarding", require more effort and be more expensive than more harmful alternatives.
Without effective external helpful governing the “solutions developed by the competition for status system” are almost certain to be more harmful and less helpful than they needed to be (like the madness of global geo-engineering experiments, only able to be fully understood after being implemented, to "solve the avoidable global geo-engineering experiment climate change problem that has been caused by the belief that the pursuit of new technology that is highly desirable and profitable will effectively develop The Required harm limiting Solution").
