Senate GOP Targets Solar, Spares Nuclear and Geothermal

Senate GOP Energy Bill Shakes Up Clean Energy Incentives

The Senate GOP energy bill introduced this week signals a major shift in how clean energy will be supported in the United States. While the Inflation Reduction Act (IRA) provided broad incentives for various renewable sources, the latest Senate proposal picks winners and losers among clean technologies. The bill specifically cuts support for solar, wind, and hydrogen while maintaining or even extending tax benefits for nuclear, geothermal, hydropower, and long-duration energy storage. Homeowners and businesses relying on solar incentives may face steep declines in support, sparking concern among climate advocates and energy startups.

Solar and Wind Lose Ground Under Senate GOP Energy Bill

One of the most immediate impacts of the Senate GOP energy bill is on solar energy. The bill proposes a 180-day window for homeowners to claim existing solar tax credits after the bill is signed—after which the credits disappear entirely. Solar leasing companies would also become ineligible for tax credits, striking a blow to a key part of the residential solar industry. Commercial solar and wind installations aren’t spared either. While the current IRA extends credits through 2032, the Senate GOP’s plan dramatically shortens the timeline. Projects starting within six months of the bill’s passage will receive the full credit, but that drops to 60% in 2026, then 20% in 2027. After that, the credit ends completely, potentially stalling long-term solar and wind growth.

Hydrogen and Carbon Capture See Mixed Results

Hydrogen startups—many of which are still in early development stages—are also under pressure. The Senate GOP energy bill aligns with the House version by ending hydrogen tax credits this year. That sudden policy change adds further instability to a sector that’s been struggling with inconsistent regulation and investment hurdles. In contrast, carbon capture projects receive more balanced treatment. While the bill removes distinctions in how captured carbon is used, it ensures that all carbon capture initiatives qualify for the same tax incentives. This uniform approach could streamline project planning and improve investment prospects for companies focused on climate-friendly industrial solutions.

Nuclear, Geothermal, and Hydropower Receive Extended Support

In a clear departure from how solar and wind are treated, the Senate GOP energy bill favors legacy and low-emission energy sources like nuclear and geothermal. Tax credits for these sectors will now extend to projects that begin construction as late as 2033—one year beyond the IRA’s cutoff. These credits then phase down gradually through 2036, providing a longer planning horizon for developers. Long-duration energy storage and hydropower also benefit from this extended runway, reflecting a strategic focus on reliable baseload and grid-stabilizing technologies. While this selective support may reshape the clean energy market, critics warn it could slow progress toward broader climate goals.

The Senate GOP energy bill marks a sharp turn in U.S. clean energy policy, selectively supporting certain sectors while scaling back others. Solar, wind, and hydrogen industries now face uncertain futures, while nuclear, geothermal, and carbon capture receive policy boosts. As debate over the bill continues, stakeholders across the energy sector will be watching closely—balancing investment risks against the evolving political landscape. For homeowners, startups, and utilities alike, the outcome of this legislation could reshape how America transitions to clean energy in the years to come.
