The US installed 43 gigawatts (GW) of new solar capacity in 2025, marking the fifth straight year that solar has been the largest source of new power added to the grid.

According to the latest “US Solar Market Insight 2025 Year in Review” from the Solar Energy Industries Association (SEIA) and Wood Mackenzie, solar and energy storage together accounted for 79% of all new electricity generation capacity installed during the first year of the Trump administration.

In other words, nearly four out of every five new power plants built in the US last year were solar or batteries.

## Solar growth in red states

More than two-thirds of the solar installed in 2025 was built in states that Donald Trump won in the 2024 election.
