Greenhouse warming 100 times greater than waste heat
What the science says...
The contribution of waste heat to the global climate is 0.028 W/m2. In contrast, the contribution from human greenhouse gases is 2.9 W/m2. Greenhouse warming is adding about 100 times more heat to our climate than waste heat.
Climate Myth...
It's waste heat
"Global warming is mostly due to heat production by human industry since the 1800s, from nuclear power and fossil fuels, better termed hydrocarbons, – coal, oil, natural gas. Greenhouse gases such as carbon dioxide (CO2 play a minor role even though they are widely claimed the cause." (Morton Skorodin)
When humans use energy, it gives off heat. Whenever we burn fossil fuels, heat is emitted. This heat doesn't just disappear - it dissipates into our environment. How much does waste heat contribute to global warming? This has been calculated in Flanner 2009 (if you want to read the full paper, access details are posted here). Flanner contributes that the contribution of waste heat to the global climate is 0.028 W/m2. In contrast, the contribution from human greenhouse gases is 2.9 W/m2 (IPCC AR4 Section 2.1). Waste heat is about 1% of greenhouse warming.
What does these numbers mean? They refer to radiative forcing, the change in energy flux at the top of the atmosphere. Or putting it in plain English, the amount of heat being added to our climate. Greenhouse warming is currently adding about 100 times more heat to our climate than waste heat.

[DB] Inflammatory snipped. Please focus on the science. And a suggestion: Paragraph breaks and periods at the end of sentences would add to the readability of your comment.

First of all, what you are doing is trying to formulate a hypothesis. Things that are theories are robust, supported by observational evidence and are testable, having survived countless experimentations by scientists who have documented their work through thousands of research papers in reputable journals.
One such theory is the radiative physics of greenhouse gases. Another is AGW. Centuries of research document and quantify their effects and they are well-supported. Since you have not even properly quantified the effects of what you propose (like the next two comments already have), let alone support it with research of your own or citations to pre-existing research in the field, what you propose fails to rise to the level of hypothesis yet.
Read the post at the top. Learn. Read the comments on this thread. Learn more. Work out the maths. Read through the links in the OP and in the comments. Learn more. If you gain support for what you propose, write it up as a plausible hypothesis complete with maths and citations to other established work which you can then use to support your position. Then bring the completed homework back here.
Until then you waste everyone's time here. And that is putting it nicely (Mr. Curtis has the paitence of a saint, and when he runs out of patience it is due to the intractability of the individual he is trying to help).
