Part of Rocky Mountain Institute’s vision of getting us off oil by 2050 is a new approach to cars: electric, half as heavy, highly aerodynamic.
RMI founder Amory Lovins on Your Call Tuesday:
“About 3/5 of our mobility fuel, which is how we mainly use oil, goes to cars and if we make the cars 2 or 3 times lighter and more slippery, they use two- or three times less energy; They need a two- or three times smaller propulsion system; They also get safer by the way, because the ultra-light materials absorb 6 to 12 times as much crash energy and can do so more smoothly. And when the propulsion system gets two- or three times smaller, you can afford to electrify it.” The first new versions from Volkswagen and BMW arrive in Germany next year.
Cars Could Help Green the Electricity System
“When smart vehicles are exchanging electricity and information with through smart buildings with smart grids, they’re adding to the grid storage and flexibility that make it easier for the grid to accept varying solar and wind power,” say Lovins.
