The United States is short millions of charging stations for electric vehicles, according to a new analysis, a threat to the EV goals set by the Biden administration, which has seen a sluggish rollout of chargers despite spending billions.

This month, the Edison Electric Institute estimated the U.S. will see nearly 80 million EVs on the roads by 2035 — a drastic increase from the more than 3 million currently on the roads. While the administration has enacted billions of dollars of spending on charging infrastructure, the White House’s goals are dramatically lower than what research suggests will actually be necessary.
