Joni Ernst, a United States Senator, backed by fellow Iowa Sen. Chuck Grassley and Alaska Sen. Lisa Murkowski, has filed an amendment to the US Senate’s tax and spending megabill.
The proposal seeks to remove a planned tax on wind and solar projects set to take effect after 2027. It also aims to change how clean energy tax credits are applied, basing them on when a project begins construction rather than when it becomes operational.
The amendment would revise two of the bill’s most contentious provisions and could provide modest relief for renewable energy projects currently targeted in the draft legislation under Senate debate.
Renewable energy supporters advocate for modifications in the tax bill
The amendment will be brought up on the Senate floor as part of “vote-a-rama” — a series of votes on a stream of amendments to President Donald Trump’s big tax-and-spending bill.
Notably, Ernst and Grassley represent Iowa, which gets more than 60% of its electricity from wind power. Additionally, other Republican senators may support the amendment.
The opposition to the Senate bill, which features a broadside from Tesla CEO Elon Musk, comes as Senators began voting on a possibly lengthy list of changes to the bill on Monday morning. This provided renewable energy supporters from both political parties one last chance to advocate for modifications.
The Senate bill would reverse incentives for wind, solar, batteries, and other clean technologies that President Joe Biden established in his 2022 Inflation Reduction Act. In addition, it would impose a new tax on those projects if they cannot demonstrate that the products are made without Chinese parts.
Those provisions were tougher on the credits than the previous Senate and House versions.
The energy analysis firm the Rhodium Group estimates that the excise tax on wind and solar energy would raise their cost by 10-20%, in addition to the loss of tax credits. Consumers would absorb those added costs, Rhodium said.
Trump’s big tax-and-spending bill faces criticism from individuals
The bill has triggered strong opposition from industry and labor groups, with critics warning of power shortages, rising prices, and job losses.
Over the weekend, Neil Bradley, an executive vice president, chief policy officer, and head of strategic advocacy at the US Chamber of Commerce, shared his opinion on the topic of discussion. Bradley says taxing energy production is always bad, whether for oil and gas or renewable sources.
He then stated that the electricity demand is expected to grow significantly, and this tax will raise prices. Therefore, based on Bradley’s argument, this needs to be eliminated.
Moreover, in an X post, Elon Musk highlighted that this would harm America. Musk continued that the cuts could threaten the progress of energy-intensive artificial intelligence technology and more.
President Trump urged Senate Majority Leader John Thune to speed up the phase-out of clean energy tax credits, pushing for a tougher stance on wind and solar. This approach contrasts with the slower sunset plan supported by moderate senators. Some lawmakers requested assistance to soften the blow to their states from canceled projects, job losses, and rising energy costs.
The renewable energy industry, manufacturing unions, and even some conservatives also criticized the new tax.
Conservative energy expert Alex Epstein advocates ending the green tax credits. Still, he appeared surprised by the excise tax, saying in a post on X, “I just learned about the excise tax and it’s definitely not something I would support.”
The US Chamber of Commerce also quickly condemned the tax. Neil Bradly, the Chamber’s executive vice president, said on social media that axing energy production is never good policy, whether oil and gas or, in this case, renewables. He noted that electricity demand will grow enormously, and the tax will increase prices. Neil insisted that it should be removed.
