America is on the cusp of an era of energy expansion. According to the newly released 2025 Sustainable Energy in America Factbook from the Business Council for Sustainable Energy (BCSE) and BloombergNEF, a broad portfolio of energy technologies – including those in energy efficiency, natural gas and renewable energy – are the key to meeting a growing electricity demand and building up America’s competitive edge.

The signs of exponential demand growth are clear. In anticipation of growing artificial intelligence and data center demand, companies like Microsoft, Google and Amazon signed 183 deals for clean power in 2024 – nearly double the amount of power purchase agreements in the prior year. These announcements set a record of 28 gigawatts (GW) in 2024, up 26% from 2022.

American-made clean energy is ready to meet this demand. Solar and energy storage hit another record in 2024, helping push renewable sources to 24% of U.S. power generation. Specifically, the contribution of wind, solar, biomass, waste-to-energy, geothermal and hydropower rose at the fastest pace among all sources of power, increasing more than 10% year over year.

Natural gas remained the largest electricity generation source in the United States, representing close to 43% of total output in 2024. Demand for U.S. natural gas across all sources rose 1.3% to reach another record of 99.7 billion cubic feet per day. Together, natural gas and renewable energy provided the supermajority of U.S. electricity generation (67%).
