But not every company that asks for money receives any at all — let alone $700 million.  So exactly how does this process work?  How fair is it? What criteria are most important?  What types of companies are favored over others, and why?  Are more mature renewables technologies, like photovoltaics (in which Solyndra plays), favored over newer ideas?  (Solyndra has a very well proven breakthrough in deployment of CIGS (copper indium gallium (di) selenide), generating a significant leap in PV efficiencies and reduction in costs).

Unfortunately, it’s not clear.  I suppose it’s not supposed to be.  Take solar thermal/CSP (concentrated solar power) as an example of a new technology.  Technologies like PV and wind have a several-decade head-start over CSP.  When I interviewed industry leader Ausra‘s founder Dr. David Mills for my book on renewables, he told me that Ausra had gotten to the second round in one of these mega-contests in which the DoE selects its favorites to back, but that they didn’t make the finals.  When I asked if he resented their decision, he — perhaps simply out of good sportsmanship and professional courtesy — said that he didn’t, and told me that he’ll simply try again another time.

I can’t count all the people who have asked us for our insights at 2GreenEnergy on this matter — and I regret that all I can turn up are anecdotal incidents like these.  I ask readers to share their own experiences with this process so that all my learn.  Thanks.
