Should you buy a plug-in car? This is a tough question with no simple answer, but as things stand in early 2021, our general response is this: If you want to make a difference, the answer is yes. If you want to save money, the answer might be no, but that depends a lot on how much electricity and gasoline each cost where you live, as well as what type of conventional car you might buy instead of an EV.
From the environmental perspective, there’s no question electric propulsion is superior despite propaganda to the contrary. This is why plug-in vehicles and regular hybrids have sold in the U.S. at all. Why they haven’t done better is because this is the land of consistently cheap gasoline and diesel fuel, and until efficient and/or clean alternatives are priced to beat the status quo soundly (either naturally or through incentives), they won’t make up a major chunk of the market. We also await vehicle technology that allows public charging speeds to rival fuel-tank fill-ups before we expect Americans who can’t charge at home to embrace pure EVs.
