Harvard Study Predicts 32 Percent Of US New Car Sales In US In 2030 Will Be EVs

A new study from Harvard's Salata Institute predicts electric vehicles will make up 32 percent of new car sales in the US by 2030, up from about 8 percent today. That is a big jump, even though it is lower than the 48 percent the researchers expected before recent federal policy changes. The biggest single factor slowing EV adoption was the end of the $7,500 federal tax credit for buying an electric car, which the study says alone cuts projected 2030 EV market share by about 6 percentage points.

The researchers say the credit will matter less over time as battery costs fall and EV prices get closer to those of gas cars. They also point to charging as the real hurdle for many buyers. As public fast chargers expand and apps make it easier to see charger status and prices in real time, the study suggests range anxiety could ease enough to boost EV sales by roughly 6 percent, about the same amount lost from ending the tax credit.

For homeowners thinking about an EV, this suggests the incentive picture is shifting: the federal purchase credit that used to lower the price is gone, but battery costs and charging networks are still improving on their own. If you are weighing an EV alongside home upgrades like a heat pump or solar panels, it may be worth checking what state-level EV incentives or charging rebates are still available, since these vary widely and change often.
