The nasayers below are amazing.  "tax payer supported"?  Everything is tax payer supported in one way or another.  Big oil has been getting tax breaks for years.  Coal mine disasters are cleaned up by the EPA (we taxpayers).  Cost?  Of course there are costs - start ups always cost more.  Zoning laws - easy to change.  I put in a 6 KW panel system and love it - annual electric bill at my home in S Calif are minus 96 bucks last year.  It will pay for itself in 10 years (and actually make money after that) - show me any other home improvement that will do that.
