Republican Senator Joni Ernst has introduced an amendment to the U.S. Senate's tax and spending megabill that would change two of the most contentious parts of that bill and could give a small boost to wind and solar projects that had been targeted in the draft being debated on the Senate floor.

Republican lawmakers are debating a bill that ramps up President Donald Trump’s assault on wind and solar power, a worse-than-expected jolt to clean energy while providing aid for fossil fuels.

Senate Republicans stunned the power industry over the weekend with a proposed new tax on wind and solar projects, part of a broader push to unravel incentives for renewable energy. Energy tax credits that were expanded during the Biden administration are wrapped up in a fierce Congressional fight over President Trump’s signature tax and spending bill.
