Are There Exceptions to the Rule that Going Electric Reduces Emissions?
“Averaged over the globe, electric vehicles (EVs) already represent about a 31-percent emissions savings” writes Ars Technica, noting results from a study which also found similar savings from energy-efficient home-heating pumps. “Even in the scenario where these technologies are promoted but the grid isn’t cleaned up much, there’s a substantial benefit through 2050.” But the researchers also separated the world into…

Will Electric Cars Last Longer Than Combustion-Engine Cars?
Long-time Slashdot reader jimminy_cricket shared Qz’s report on some of “the highest-mileage Teslas in the world”: Few have driven a Tesla to the point at which the vehicle really starts to show its age. But Tesloop, a shuttle service in Southern California composed of Teslas, was ticking the odometers of its cars well past 300,000 miles with no signs of slowing……
