Summary
Global clean energy investment surpassed $2.3 trillion last year, outpacing fossil-fuel spending for the second year in a row. Solar and wind have become the default choice for new power generation due to lower costs and faster construction timelines. U.S. clean-energy investment reached a record $378 billion in 2025, a 3.5% increase driven primarily by economic factors rather than policy. Unsubsidized solar and wind projects are now cheaper than nearly all fossil-fuel alternatives.
