EV Sales Soar, but Electrifying Big Rigs Remains a Challenge

Electric vehicle sales grew 65% last year, with nearly all the growth coming from surging purchases of light-duty passenger EVs. Mitigating climate change will require vehicle electrification among a broader range of automobiles. Heavy-duty vehicles, like tractor trailers, are only 10 percent of vehicles on the road, but they are responsible for 28% of U.S. greenhouse gas emissions from the auto sector, showing that electrifying tractor trailers (also called big rigs, semis, or 18-wheelers) is a critical challenge that must be addressed.
