Media Tip Sheet: The Impact of the Megabill on the Energy Sector


May 29, 2025

WASHINGTON (May 29, 2025) – The “One Big Beautiful Bill Act” was passed by the House of Representatives last week and, if it clears the Senate as it is now, critics say it would effectively end most clean energy tax credits and reverse much of the US agenda to mitigate climate change.

According to the Massachusetts Institute of Technology and the Rhodium Group, $161 billion has been invested in large solar and battery projects since the Inflation Reduction Act passed in 2022 and experts say these investments are at risk. In addition, the bill as it stands now would cut incentives to invest in the electric vehicle industry.

John Helveston, assistant professor of engineering management and systems engineering at the George Washington University, is an expert in electric vehicles, innovation and technology policy. He’s interested in understanding the factors that shape technological change, with a particular focus on transitioning to more sustainable and energy-saving technologies. Helveston’s research on electric vehicles has examined the resale value of EVs, the mileage of EVs, and the incentives needed to get people to buy in. He has also published on international trade policies and their impact on scaling up low-carbon energy technologies.

Helveston can also talk about how the bill would increase electric and gas bills for consumers and lead to increased emissions in the air.
