What The Science Says:
As with solar energy, complete reliance on wind energy would pose intermittency challenges. However, wind, solar, and storage together can provide the majority of the country’s electricity without compromising reliability.
Climate Myth: Wind energy is unreliable
"[B]ecause of the wind’s intermittency and high variability, they do next to nothing to reduce the need for other fuels." (Wind Watch)
As with solar energy, complete reliance on wind energy would pose intermittency challenges. However, wind, solar, and storage together can provide the majority of the country’s electricity without compromising reliability1, and energy efficiency and grid flexibility mechanisms can support a renewable energy-based grid. (Lovins 2017) Hydropower has also been found to support wind and solar by compensating for intermittency in those sources (Shan et al. 2020). Moreover, building more long-distance transmission infrastructure can enable greater reliance on wind and solar generation2, and linking offshore wind projects through offshore transmission networks is also expected to enhance grid reliability.3 A National Renewable Energy Laboratory report concluded that “wind power can support power system reliability” by providing “active power controls,”4 which are mechanisms for balancing the power generated by wind farms with the power consumed on the electricity grid (van Wingerden et al. 2017). And although the reliability of wind and solar energy was questioned following Texas’ widespread power outages in the winter of 2021, Texas’ grid failure was primarily caused by freezing natural gas infrastructure, rather than failures at wind and solar farms, though nuclear, coal, and wind also experienced disruptions at a smaller scale.5 (also Busby et al. 2021)
Wind energy has already been successfully incorporated into the United States’ electric grid at significant scale.6 Domestic energy production from wind more than tripled between 2011 and 2022, from 120 billion kilowatt-hours (2.9% of total energy production) to 435 billion kilowatt-hours (10.3% of total energy production).6 Some states have seen even more rapid growth. In 2021, wind energy accounted for 58% of electricity production in Iowa, and 43% of electricity production in Kansas.7
Wind power has enabled Iowa not only to reduce energy costs, but to generate additional revenue by selling excess power to neighboring states during shortages.8 Today, Iowa is considered one of the states with the most reliable energy systems.9 In California, electricity generated from wind power increased from roughly 3% in 2009, to roughly 7% in 2022.10 Electricity generated from natural gas declined from roughly 56% in 2009, to roughly 47% in 2022. Yet even with this increased reliance on wind power, California’s grid reliability has remained consistent, and largely above national averages.11 California has even been able to briefly meet 103% of its energy demands exclusively from renewable sources, demonstrating that a large economy can by powered by renewable energy.12 The UK has also made substantial progress utilizing wind power, which was responsible for 26.8% of overall energy production in 2022, and which helped stave off the worse impacts from the energy crisis following Russia’s invasion of Ukraine.13
