Renewables account for more than two thirds of new generating capacity additions in the U.S. This means that renewable energy is claiming an increasing share of the national generation mix. EIA estimates that wind power accounted for 9% of U.S. electricity generation in 2020., surpassing hydropower as the predominant renewable electricity generation source in 2019.
The agency expects wind to make up 31% of the nearly 40GW of new generating capacity in 2021. That’s nearly double the share claimed by new gas-fired generation (16%). Solar comes in first, accounting for 39%, according to EIA.
