The Impact of Electric Vehicles on US Energy Costs and Security
Electric vehicles (EVs) are often seen as a luxury purchase, but their widespread adoption could lead to significant economic and energy security benefits for the United States. Recent research highlights how transitioning to EVs could reduce gasoline prices and enhance the country’s energy exports.
According to a study published in Energy Policy, moving towards a future with more electric cars could decrease US household energy expenses by over 6% by 2035, with a reduction of more than 4% at gas stations. This shift could also result in a 7% decrease in oil imports and a nearly 4% increase in oil exports.
However, these advantages might be at risk due to the federal government’s recent decisions to revoke national EV incentives and alter rules aimed at increasing vehicle fuel efficiency. These changes could impede the anticipated benefits, according to the study’s authors, who conducted their research before these federal decisions were made.
Georgia Tech PhD candidate Niraj K. Palsule explains, “Proponents of eliminating fuel efficiency standards and other EV-boosting policies often frame those regulatory approaches as consumer-unfriendly, but our analysis shows that such policies have many long-term benefits, both for consumers and for the nation’s energy security.”
The researchers used an advanced version of the National Energy Modeling System, developed by Carter School researchers, to better simulate energy production, consumption, and demand dynamics. They assessed the impact of vehicle fuel efficiency standards and other policies from 2022 to 2035, comparing scenarios with and without EV incentives and varying fuel efficiency standards.
Their findings indicate that newer policies, as opposed to pre-2024 regulations, would reduce household energy expenses and gasoline consumption across all income levels, decrease oil imports, and boost oil exports by 2035.
These savings arise from two main pathways. Firstly, the increase in electric vehicles leads to reduced gasoline and oil import needs, thereby lowering prices for consumers. While wealthier families might save around 6.4% on energy costs, lower-income households still using gasoline vehicles in 2035 could see a 6.6% reduction in energy expenses.
Secondly, advancements in battery technology, driven by a growing EV market, could lower energy storage costs for utilities. This innovation, described by Palsule and Marilyn A. Brown, a professor of sustainable systems, could stabilize or even reduce home electricity costs.
The research also suggests that with stable global oil demand, US oil producers could export surplus oil, bolstering the US’s role as a net energy exporter. During geopolitical disruptions, such as those in Ukraine or Iran, increased electric vehicle usage could help shield the US economy from shocks.
Despite these potential benefits, Palsule and Brown remain cautious, noting that the repeal of federal rules and challenges to emissions regulations in California and other states could hinder progress. They emphasize that a cohesive national strategy is necessary to maximize the benefits of EV adoption.
“Maximizing the benefits of a transition to electric vehicles that would both help consumers and strengthen the nation’s energy security can only come with a nationwide strategy,” says Marilyn A. Brown.
The research was funded by the Ray C. Anderson Foundation, Georgia Tech’s Energy Policy and Innovation Center, and the Brook Byers Institute for Sustainable Systems at Georgia Tech.
