Clean energy capital spending hit $74 billion in the first half of 2026 and is tracking toward a record $180 billion for the year, even after federal incentive rollbacks. Utility-scale battery storage has reached 52 gigawatts after three straight years of 70% average annual growth, with grid operators lining up another 54 GW through 2028.
Clean energy investment keeps climbing despite the rollback of Biden- and Obama-era federal incentives. Clean energy capital expenditures reached $74 billion in the first half of 2026 and are on track for a record $180 billion by year-end, according to fintech firm Crux's State of Clean Energy Finance mid-year report. According to Politico's E&E News: Crux CEO and co-founder Alfred Johnson said "the market is proving resilient".
Battery storage grows 70% a year
The investment surge is running alongside a rapid buildout of battery storage capacity. Utility-scale battery storage capacity grew at an average of 70% per year over the past three years to reach 52 gigawatts, with 8.3 GW added in the first half of 2026 alone. Interesting Engineering reported that the expansion depends mostly on pairing batteries with solar photovoltaic plants to capture wholesale price arbitrage, letting operators store excess power at peak production and sell it later when demand and prices rise.
Grid operators plan to add another 54 GW of battery capacity by the end of 2028, which would double the nation's storage capacity again by 2030 compared with current levels.
Data centers and volatile fuel markets drive demand
Demand from data center hyperscalers and the artificial intelligence boom is spurring investment across energy projects, particularly renewables, because of their advantages in energy security and affordability. Those advantages have been underscored by volatility in fossil fuel markets tied to the war in Iran and related supply-chain vulnerabilities. As quoted by Reuters, NextEra Energy CEO John Ketchum said renewables and storage remain the fastest way to add new electrons to the grid until more gas-fired generation can be built.
Portuguese utility EDP is directing about $5.3 billion, more than half of its capital budget, toward United States renewables projects over the next three years. According to Semafor, EDP chief executive Miguel Stilwell d'Andrade said the industry is arguably in one of the best periods to invest in renewables in the US in the last 20 years.
China leads, Europe moves to catch up
The storage buildout extends well beyond the United States. China controls more than half of global battery storage capacity, while the European Union formalized a plan this month to triple its own storage capacity by 2030. European leaders are counting on storage and renewable expansion together to stabilize the continent's energy markets against future supply shocks.
