The research appearing in Energy Policy analyzes vehicle policy and market outcomes from 2022 to 2035 using a version of the National Energy Modeling System created by Carter School researchers. It compares a baseline with no new federal EV incentives and only pre-2024 fuel efficiency standards to a middle path between the now-repealed federal standards and the rules adopted by California and 17 other states.
Under widespread EV adoption by 2035, the study finds household energy bills would fall by more than 6% overall, with pump spending down by over 4%. The analysis also projects a 7% decline in oil imports and nearly a 4% rise in oil exports by 2035. Estimated household savings differ slightly by income: upper-income households would save about 6.4% on energy, while lower-income households likely to still drive gasoline cars in 2035 would spend about 6.6% less.
- Lower gasoline demand would reduce pump prices for all consumers.
- Stronger EV demand would speed battery and efficiency improvements, lowering storage and utility costs.
Because global oil demand is unlikely to fall, US producers could export more oil that otherwise would become gasoline, strengthening the country as a net energy exporter and helping cushion economic shocks such as conflicts in Ukraine or Iran. The authors caution that benefits are now uncertain after repeal of national EV incentives and a federal rollback of EV-boosting rules. Niraj K. Palsule notes long-term consumer and security benefits from standards, and Marilyn A. Brown says a nationwide strategy is necessary to maximize those gains. The research was supported by the Ray C. Anderson Foundation, Georgia Tech’s Energy Policy and Innovation Center, and the Brook Byers Institute for Sustainable Systems; source: Georgia Tech (reported on Futurity).
