U.S. Clean Energy Prices Could More Than Double as AI Demand and Subsidy Cuts Deliver a One-Two Punch
0xBroomberg
US clean-energy power purchase agreements are set to rise 40% to 120%, as expiring tax credits and AI data centres' hunger for green power squeeze manufacturers and traditional buyers out of the market.
How much are prices rising — and why now?
A LevelTen Energy survey of US solar and wind developers shows PPA — power purchase agreement, a long-term contract to buy electricity — prices are expected to jump 40% to 120%.
In Texas, the PPA price could leap from $55 to $121 per megawatt-hour. This means → the cost of buying clean power would more than double.
The trigger is the "One Big Beautiful Bill" pushed by the Trump administration: renewable projects breaking ground after July 4, 2025 will lose Biden-era tax credits worth roughly 30% of development costs.
Can installation growth survive without subsidies?
Wood Mackenzie data shows US solar capacity nearly doubled between 2022 and 2025, from 141 GW to 279 GW.
But that surge was subsidy-driven. In plain terms = subsidies powered the "capacity doubling" pace; remove them, and growth slows sharply.
This reflects a deeper signal: US clean energy is nowhere near cost-competitive enough to stand on its own without policy support.
How is the AI arms race pushing prices from the demand side?
BloombergNEF data shows Meta and Google are the world's largest renewable-energy contract buyers in 2026.
The US Energy Information Administration projects US power demand will grow 25% to 50% by 2050 — data centres are the core driver of incremental demand.
This means → data centres are willing to pay a premium to lock up scarce subsidy-eligible projects, crowding out hospitals, factories, and retailers.
Beyond subsidy cuts, what else is driving costs up?
According to the American Society of Civil Engineers, transformer costs have risen 60% to 80% since early 2020; solar labour costs climbed 15% in 2025.
Longer grid-interconnection queues, permitting delays, and rising financing costs are all tightening developers' room to offer discounts.
Mona Dajani of law firm Cooley said "the underlying fundamentals have fundamentally changed." In plain terms = developers used to absorb cost pressure by cutting margins — now the cost floor itself has been raised, and there is nothing left to give.
Can Big Tech still keep its climate promises?
Microsoft is reportedly considering dropping its goal of hourly clean-power matching by 2030; Google has warned that its "moonshot" climate targets are getting harder, even as it signed a record number of clean-energy deals in 2025.
Yet corporate climate goals have not been abandoned wholesale. Don Leavens, chief economist at the National Electrical Manufacturers Association, said "demand for clean PPAs will persist" — globally operating companies must respond to climate pressure worldwide, not just in the US.
LevelTen Energy warned: once subsidy-eligible projects are absorbed, "they're gone." This means → buyers still on the fence today will face higher prices and weaker bargaining power tomorrow.
