New Report: Hummer EV is Worse for the Environment than Chevy Malibu

Jason Lomberg, North American Editor, PSD

­I guess turnabout is fair play…even when it comes to a 9,000-pound vehicular juggernaut. Back in 2007, a report from the Oregon-based CNW Market Research famously claimed that the Hummer — the poster child for gas guzzlers — was more energy efficient than the Toyota Prius hybrid. 15 years later, a n

­EVs can now achieve similar mileage as gas-powered vehicles, but it still takes more time to charge an EV than to refuel a gas vehicle. Charge time is approximately equal to the amount of energy delivered to the battery divided by the charging power; therefore, it is desirable to use as much power as possible to
