The industry can "say" any thing that will sell green tech.  The engineering facts, not wishes and dreams, say different.  Renewables will prove to be one of the, if not the biggest con of the last 59 years, not because it doesn't work in some scales, it doesn't work on utility scales.  You obviously need about 2 years of "boning up" to get it.  

The simple math and numbers above you didn't refute as with most of the info I posted,  You obviously have little if any engineering background to judge or analyze the info, or, you simply didn't read it.  In the end, the renewables will die a long, drawn-out death of screaming enviros who also don't understand what "energy density" means to engineering and economics.
