US President, Donald Trump, signed an executive order ending federal support for solar and wind energy projects in the United States. The measure, part of his broader “energy dominance” strategy, seeks to eliminate subsidies he describes as “costly, unreliable, and controlled by foreign adversaries.”

The order directs the Treasury Department to begin, within 45 days, enforcing the termination of tax credits outlined in Sections 45Y and 48E of the Internal Revenue Code. These credits have until now benefited clean electricity projects. The order also calls for tighter rules to prevent the artificial acceleration of project eligibility, restrict broad safe harbor provisions, and strengthen the criteria for determining when construction has officially begun.

At the same time, the Secretary of the Interior is instructed to review all regulations, guidelines, and policies that grant preferential treatment to renewable energy over so-called “dispatchable” sources such as natural gas, coal, or nuclear power—with the goal of removing such advantages for wind and solar facilities.

The initiative is grounded in the newly passed One Big Beautiful Bill, which states that clean energy projects will no longer qualify for tax incentives if they have not begun construction before 2026.

“Reliance on green subsidies threatens national security by making the United States dependent on supply chains controlled by foreign adversaries,” the order states. Trump also argues that the expansion of solar and wind facilities “compromises the U.S. power grid” and “undermines the beauty of our nation’s natural landscape.”

Instead, the president promotes an energy strategy based on “affordable, reliable, and dispatchable domestic sources,” including fossil fuels, nuclear power, and emerging technologies, aiming to reinforce U.S. energy independence and economic growth.

Relevant departments are required to report back to the president within 45 days of the order, outlining the measures taken to implement its provisions.
