US Renewables Reach 30% of Power Capacity as Fossil Fuels Decline

New federal data shows renewable sources now account for 30% of U.S. generating capacity, with solar capacity tripling and battery storage growing twentyfold over the past five years. Wind generation expanded by a third, and renewables plus storage are projected to add nearly 83 gigawatts by mid-2027 while fossil fuel and nuclear capacity shrink. The growth continues despite the current administration's emphasis on fossil fuels, according to an analysis by the Sun Day Campaign.

The Sun Day Campaign's analysis of EIA data reveals a dramatic scaling of clean energy infrastructure over the past half-decade. Utility-scale solar tripled, small-scale solar more than doubled, wind grew by a third, and battery storage expanded twentyfold. During the first half of 2026, renewable generation rose nearly 11% year-over-year, with wind and solar combined supplying over 22% of domestic electricity.

Looking forward, renewables and storage are
