With all the limits on electric vehicles—battery life, cost, the availability of charging stations—you might expect that at most 50 percent of the vehicles on U.S. roads could be replaced by more-sustainable cars.  Buckle up: It’s 87 percent, MIT reckons, in a study published Monday in the journal Nature Energy…

Areas with more extreme temperatures—using heating or cooling systems lowers an electric vehicle’s driving range—and where such larger vehicles as trucks and SUVs are more common will be less likely to increase their use of EVs, said Jeremy Michalek, an engineering professor at Carnegie Mellon and director of the university’s vehicle electrification group. Michalek, who wasn’t involved in the study, said he prefers to focus on the most challenging days for vehicles rather than the average conditions.
