Do you think that someday as many homeowners that own cars will own the Solar PV power plant on their roof?

Seems to me that when cars were first invented and people owned horses, and buggies and carriage houses, they denied that cars were reliable and worth the investment. Here in CA you can buy a solar PV system, it's connected to the power company with a bi-directional meter, it's sized so that you get your power from the power company at night and bad weather, and they buy your excess power when your family is at work and school. NO BATTERIES unless you want back-up power from the grid. Most don't have batteries. Then there is CSP, those giant trough-like concentrated solar power plants in the desert. I square mile of CSP could power the country. Sure we'd have to update the grid. The biggest resistance is coming from the Nuclear and Petroleum industries. They want you to think those are better options. Nuclear is a dead end game, we don't need it and it's too dangerous. There is a 30% Federal tax rebate -- NOT A SUBSIDY -- no more than any other allowable deduction is a subsidy. The power company in many states like CA, NJ, NY and 21 States will also pay a big portion of your initial cost? Why? They get to buy the excess power from your roof cheaper and locally. It's win/win. If we manufactured here, and people bought the systems like they do cars, the market would drive the industry. Solar, Wind, Hydo, Tidal these are the future of energy and they are renewable. Oil is half gone refered to as "Paek Oil" they will squeeze every dime of profit before it's gone. Would be better to see to it petroleum lasts longer. Corn ethanol is a loser but switch gr ethanol is a winer, made from weeds. Why is corn ethanol pushed instead? The corn industry. It's corporatism driving what is really best into the ground with misinformation and propaganda to head off the emergence of Renewable Energy which is the best way to go. Solar PV on your roof is distributed solar (not a huge power plant) depending on where you live and your local power rates the payback can be 8 years, warranted for 25 years, that's 17 years of free power. The current energy industry is dead set against US buying into that reality, hence all the misinformation. I know a family who has solar and wind turbines. The turbines work great in winter and the solar work great in summer, they sell excess power to the power company and get power when the solar and wind systems are not at their best. Works great and saves them a bundle. That's in CO.
