2020 US electricity generation data are in from the US Energy Information Administration. Crunching the numbers, renewable energy accounted for 20.6% of US electricity generation last year. That was led by wind power, which accounted for 8.3% of US electricity generation, followed by hydropower at 7.2% and solar power at 3.3%. As reported last month, 77–80% of new US power capacity came from solar and wind power in 2020. However, power plants typically last decades and it takes a long time for significant changes in electricity generation to show capacity trends. If we look a little bit further back in the electricity generation data, we can see that renewables are indeed growing their share of the electricity generation pie. In 2018, 17.5% of electricity generation came from renewables — 6.5% from wind power, 6.9% from hydropower, and 2.2% from solar power.
