When it comes to energy policy, the “One Big Beautiful Bill Act” – the official name of a massive federal tax-cut and spending bill that House Republicans passed in May 2025 – risks raising Americans’ energy costs and greenhouse gas emissions.

The 1,100-page bill would slash incentives for green technologies such as solar, wind, batteries, electric cars and heat pumps while subsidizing existing nuclear power plants and biofuels. That would leave the country and its people burning more fossil fuels despite strong popular and scientific support for a rapid shift to renewable energy.

The bill may still be revised by the Senate before it moves to a final vote. But it is a picture of how President Donald Trump and congressional Republicans want to reshape U.S. energy policy.

As an environmental engineering professor who studies ways to confront climate change, I think it is important to distinguish which technologies could rapidly cut emissions or are on the verge of becoming viable from those that do little to fight climate change. Unfortunately, the House bill favors the latter while nixing support for the former.

Wind and solar power, often paired with batteries, are providing over 90% of the new electricity currently being added to the grid nationally and around the world. Geothermal power is undergoing technological breakthroughs. With natural gas turbines in short supply and long lead times to build other resources, renewables and batteries offer the fastest way to satisfy growing demand for power.

However, the House bill rescinds billions of dollars that the Inflation Reduction Act, enacted in 2022, devoted to boosting domestic manufacturing and deployments of renewable energy and batteries.

It would terminate tax credits for........
