According to the U.S. DOE’s Office of Energy Efficiency & Renewable Energy, every year except 2011, the majority of plug-in electric vehicles sold in the U.S. were also made in the U.S.
In 2018, roughly 75% of all plug-ins sold in the U.S. were made in the U.S., which is quite an achievement. The remaining 25% falls on:
- Japan: 9%
- Germany: 5%
- Rest of the world: 11%
A big reason behind the result is the huge share of Tesla sales out of overall volume - around 53% in 2018 according to IEVs estimates, and over 52% so far this year (through the end of May).
By the way, it also means that the majority of plug-ins sold in the U.S. are made in California.
