As opposed to say the government which always makes the politically right decisions, ie which ever group contributes the most to their re-election campaigns. It's been tried, see the Soviet Union; look at the results.
Because coal and oil make sense perhaps. Do some rough calculations for wind turbines for example: 3-5 MW per turbine with a moderate wind. The average coal/gas/oil fired power plant is ~1000 MW. Now add in the "prairie preservationists", the Kennedys, and all of the environuts who don't want to see turbines or power lines. Not to mention *storing* the energy for when the wind isn't blowing.
