Although there has been some form of electric cars for several decades, recently the quest for lower-cost transportation and—for environmentalists—the pursuit of alternatives to fossil-fuel has led to the growing popularity of electric cars. The leader today is Tesla, and its founder Elon Musk, who has just campaigned using the medium of “Battery Day”. He is in lockstep with California’s governor, Gavin Newsom, who is joining a dozen-plus other countries in prohibiting sales of gasoline/diesel-fuel-powered cars. For this to occur, there will be a need for a lot more electric car charging stations and more standardization. Although the new law appears to exclude current cars on the road and ones that will be sold before the deadlines, owners of cherished models will be able to retrofit them with electric motors.
