U.S. investment across the energy transition grew 3.5% in 2025.
• U.S. investment across all the energy transition sectors that BloombergNEF tracks – including renewables, electrified transport, decarbonization of industrial processes, and grids, among others – grew 3.5% year-on-year to a record $378 billion. This total is equivalent to 1.2% of 2025 U.S. GDP.
• As electricity demand surged with the build of artificial intelligence (AI) infrastructure in 2025, investment in the U.S. electricity grid jumped 9.5% to $115 billion.
Global investment in sustainable energy once again shattered records in 2025.
• Globally, sustainable energy investment reached over $2.3 trillion in 2025. China continued as the global leader with $800 billion in 2025 investment, equivalent to about 4.1% of the country’s estimated GDP.
Corporate demand for clean, 24/7/365 power soared in 2025.
• Corporate power purchase agreements signed for zero-carbon electricity reached 29.5 GW in 2025, the highest annual total on record.
• The year was marked by a growing share of nuclear, hydropower, and geothermal contracts as tech giants doubled down on clean, baseload power for AI data centers.
The creation of U.S. domestic supply chains remained a priority in 2025.
• By the end of 2025, the United States had 295 gigawatt-hours (GWh) of annual lithium-ion battery manufacturing capacity, a 56% increase year-on-year.
• However, nearly 10% of the announced investment in clean tech supply chains since the passage of the Inflation Reduction Act was cancelled following the rollback of incentives under the One Big Beautiful Bill Act (OBBBA) in 2025.
• The U.S. South has attracted manufacturers with low-cost electricity, favorable tax regimes, inexpensive land, and flexible labor markets, reinforced by generous state-level incentives. Solar manufacturing is especially concentrated in the South, led by spending in Texas and Georgia.
