How EV Policies Influence Fuel Market Dynamics

State and federal regulations designed to increase adoption of electric vehicles (EVs) are likely to result in lower gas prices, lower household energy bills, and better U.S. energy security, according to a new analysis.

Past studies have mostly focused on the effects of EV-promoting regulations and fuel efficiency standards on greenhouse gas emissions in the transportation and energy sectors. The new study looks across the entire economy, highlighting cascading benefits of the EV transition largely overlooked in the past that are “not confined to early adopters or only to the transport sector,” says study team member Niraj Palsule, a graduate student at the Georgia Institute of Technology in Atlanta.

Palsule and his collaborators used a version of a computer model, the National Energy Modeling System, to project the impact of EV-promoting policies from 2022-2035. Their analysis incorporates Biden Administration fuel economy standards expected to increase EV market share to 69% by 2032, as well as California regulations (also adopted by 17 other states) that target a shift to 100% zero-emission vehicles by 2035.

In the real world, the Trump Administration has repealed EV incentives and rolled back fuel efficiency mandates. The state-level rules remain in place, but have faced court and administrative challenges, and may not be as effective without a nationwide policy, the researchers say.

The analyses in the study were conducted before these policy changes. But in the current context, with a fossil-fuel-friendly U.S. Executive Branch and supply shocks from military conflict with Iran, the study represents something of a road-not-taken.

Under the EV-friendly policies, U.S. households would see 6% lower energy bills and 4% lower gasoline expenditures, the researchers found.

Oil imports would decrease by 7%, and exports would rise by almost 4%, representing an increase in U.S. energy independence and security.

The researchers also evaluated the effect of the policies on different income groups, a breakdown that has been overlooked in past analyses. Not surprisingly, higher-income households garner the most savings on fuel due to switching from gasoline to electric vehicles.

But low-income households actually benefit the most, saving 6.6% on energy overall even though they are less likely to be able to afford EVs. This is because reduced demand for gasoline leads to falling gas prices and home energy bills.

These savings depend on a “domino effect” triggered by battery technology improvement enabling utilities to store energy in battery banks more cheaply, the researchers found.

“The most striking finding was how essential grid-connected standalone battery storage is to making an equitable and clean EV transition,” Palsule says. “Without storage, high EV penetration can potentially drive electricity prices up.”

Fuel efficiency standards and EV mandates are often portrayed as a burden on consumers. But the findings suggest that these can be consumer-friendly policies in the bigger picture, the researchers argue. And just looking at greenhouse gas emissions vastly underestimates the benefits of the EV switch.

Policy, technology, and economics, however, never remain static and have a tendency to bump into each other in unexpected ways. The researchers are now exploring the consequences of the EV transition in the context of a return to fossil fuel-friendly policy, the advent of nuclear small-modular reactors, and increasing energy demand from data centers and AI, Palsule reports.
