For those tired of winter, you’re not alone. Electric cars hate the cold, too. Researchers have conducted the first investigation into how electric vehicles fare in different U.S. climates. The verdict: Electric car buyers in the chilly Midwest and sizzling Southwest get less bang for their buck, where poor energy efficiency and coal power plants unite to turn electric vehicles into bigger polluters. Scientists at Carnegie Mellon University (CMU) in Pittsburgh, Pennsylvania, began their research by pulling public data from FleetCarma, a company that tracks vehicle performance among car fleets operated by governments and businesses.
