As it stands right now, electric cars will not be feasable for about 20 years. Our aging power grid can barely keep up to the demand now. Remember the blackout on the east coast a few years ago? The rolling blackouts in California? Now try everybody hooking up a battery charger or two between 5 and 7 o'clock an night, along with running their air conditioners in the summer. We will need more power plants, I can hear the liberals belly aching already. And nobody wants a power plant in their backyard. They are trying to put a new power line from upstate NY to the NYC area and the fight is unreal. Nobody wants it coming anywhere near them. They are making up anything to stop or divert it. I think they found a distant cousin to the spotted owl nearby that was thought extinct for the last 1.687 million years, give or take a month. So, how many years for more power plants and upgrade the power grid? 20 years may be figuring on the early side.
