Solar power

The US installed 50 gigawatts (GW) of new solar capacity in 2024, the largest single year of new capacity added to the grid by any energy technology in over two decades. That’s enough to power 8.5 million households.

The solar industry is bracing for a turbulent year, and SolarReviews’ newly released 2025 Solar Industry Survey lays out exactly why. The survey, now in its third year, gathered insights from solar companies across the industry between December 2, 2024, and January 3, 2025, covering everything from the Inflation Reduction Act to workforce development and the state of the supply chain.

Renewables increased their output by almost 10% and provided nearly a quarter of US electrical generation in 2024, according to newly released US Energy Information Administration (EIA) data.

British energy giant National Grid has reached a deal to sell National Grid Renewables in the US to Canadian investment firm Brookfield Asset Management for $1.74 billion.

GAF Energy has launched an upgraded version of its Timberline Solar nailable shingle, the ES 2, which delivers 23% more power per shingle.

Danish renewables developer European Energy (EE) has completed the sale of its largest solar farm in the US to date.

Clean energy investments took a serious hit in January, sinking to their lowest point since the Inflation Reduction Act (IRA) supercharged the industry with tax credits and incentives. Growing uncertainty around the future of these policies – especially with the Republican-majority Congress debating potential rollbacks – has led to a sharp drop in new projects and an increase in cancellations, reports E2.

The International Energy Agency’s (IEA) newly released “Electricity 2025” report predicts that global power consumption will jump nearly 4% annually through 2027. That’s like adding an entire Japan’s worth of electricity use every year for the next three years.

The Nature Conservancy (TNC) and the Cumberland Forest Limited Partnership are turning former Appalachian coal mines into clean energy hubs. They just announced new agreements with Sun Tribe Development and ENGIE to build 14 solar farms and three battery storage systems across 360 acres in Virginia, Tennessee, and Kentucky.

Renewable energy – solar, wind, geothermal, hydropower, biomass – accounted for more than 90% of total US electrical generating capacity added in 2024, according to data released yesterday by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY campaign.

Solar alone accounted for over 81% of the new capacity. Moreover, December was the 16th month in a row in which solar was the largest source of new capacity.

A coalition of clean energy groups – representing over 2,000 companies and hundreds of billions in private investment – is holding more than 100 meetings today with bipartisan members of Congress to underscore the critical role of IRA clean energy tax credits.
