can return to pre-Space Age, and try to live with wind/solar power as the main means of electricity generation, you would do well to investigate the truth of the lifestyle you cavalierly want to inflict upon everyone. You CAN go-solar or wind for a few hundred dollars, but, you'll be severely limited to subsistence level existence. Those who so choose should be able to, but I'd never curtail ANYONE else's right to live in the 21st Century, rather than early 20th! Oh, when the equipment fails - it WILL sooner than later - if you don't have 100s or 1000s of dollars saved, depending on size/quality of the system, you're dead-in-the-wind (or sun!). Oh, you better have a GOOD, fuel generator for when its dark or still or something breaks!
