One of the benefits of electric cars is that slowing down becomes a useful activity. Regenerative braking recovers energy normally lost as friction heat, as it does when the accelerator pedal is not pushed and the car is coasting.

Seven days before the advent of a new presidential administration, the U.S. Environmental Protection Agency has locked in planned auto-emission standards through 2025. The emission limits tie directly to fuel-efficiency rules issued by the NHTSA, effectively requiring those rules to stay the same as well. Announcing its final determination this... ![Tesla Supercharger stations at Harris Ranch, California, in April 2013 [photo: TeslaTap.com]](http://images.hgmsites.net/tmb/tesla-supercharger-stations-at-harris-ranch-california-in-april-2013-photo-teslatap-com_100494759_t.gif)
