A friend crunched the numbers that show that if every building produced slightly more than enough solar power to power their own use, then when it is all wired together there would be enough for everyone all the time. This is called "distrubuted power generation". When she presented her finding to energy honchos in Chicago they asked her where they would put the meter. Duh! Shortly thereafter she was offered a research position for Opec for 1 mil per year in Venice. When she asked what kind of research they wanted they said absolutely none. Distributed power is the answer to all of the issues we face. The problem we face are those super wealthy individuals who feel they are entitled to be the masters of the universe. Why does no one complain about this entitlement?
