All new technologies are cost "prohibitive" when first introduced.  The costs are reduced with time.  Both solar and wind production technologies are experiencing this right now.  My folks bought our first television in 1949...a cabinet about the size of a volkswagen and a screen smaller than some laptop computers.  It cost $849 in 1949 money, that equivalent to about $8500 in today's dollars. 

Just like TVs,  those renewables are getting cheaper and more cost competitive every day.   That's, IMO, a very good thing.  Gary Crum
