U.S. Battery-Electric Share of Light-Duty Vehicles on the Road, EIA Projection (Baseline Case)

## What this measures

The share of all light-duty vehicles on U.S. roads (cars and light trucks such as SUVs and pickups) that are battery-electric, year by year to 2050, as projected by the U.S. Energy Information Administration in the Counterfactual Baseline case of its newest Annual Energy Outlook. Every point is EIA's projection, not a count.

## Why it matters

Fleet turnover is slow: a vehicle stays on the road for well over a decade, so the stock share shows how fast gasoline demand, charging load and auto parts markets actually change. The two EIA cases bracket how much federal tailpipe rules matter.

## How to read it

Percent of the light-duty vehicle stock. EIA's Counterfactual Baseline case: laws and regulations as of December 2025, including EPA's 2024 tailpipe greenhouse gas standards for light-duty vehicles from model year 2027. EIA says this case "was known as the Reference case" in earlier editions. In AEO2026 the share rises from 2.08% in 2025 to 46.13% in 2050 (154.4 million of 334.8 million vehicles). Compare with the alternative transportation case (eia.aeo.bev_share_ldv_stock.alt_transportation.projection): the gap is EIA's estimate of the rules' effect on the fleet.

## What it does not say

It is a model projection (EIA's National Energy Modeling System) under stated assumptions, not a forecast of policy, prices or technology. Battery-electric means the 100-, 200- and 300-mile electric cars and light trucks in EIA's table; plug-in hybrids are not counted. EIA labels every year from 2025 a projection. A new edition replaces the whole path.

## History

Single release: the projection path from the newest Annual Energy Outlook, one point a year to 2050. Each new edition replaces the whole path, so the series holds one edition at a time; EIA labels every year in it a projection, so it has no measured history.
