To @Neo1, is not the cheap oil, it is the cheap natural gas that is killing everything including solar and wind...as an example the payback time on solar panel in Vancouver, BC where I live is 32 years! ...this is calculated based on constant solar output over those 32 years so it doesn't include effiency drop off that the article discusses...Kris
Oh yeah, we can go around fantasizing all we want but solar has a long way to go to make it feasible for mass deployment across countries. It's hard work, I know, but each small progress takes us a little bit closer to that goal.
I bet that cheap oil is killing this industry..
