What do you want to read that stuff for anyway? Its all just a lot optimistic fluff and dander. A lot of the RE power potential is regarded as an average. Most of those places will "swing the average" in favor of optimism. I think they call it "forward thinking." I've been reading that stuff for over 30 years. Its been pretty much the same all the while. What RE could have been and what it has become, I see as two different things. It would seem to me that for the sake of making profits, RE just wants to "slip into bed" with the established energy infrastructures and the politicians. I may be an opponent in some respects. Mostly all of the hype surrounding RE. I've lived off grid for almost 30 years, only the last 10 with solar electricity. I am a proponent of the simple fact that, where as 6 billion people need electricity in order to live, the human race does not need electricity in order to survive on the planet Earth. I am not pessimistic and I don't consider myself "backwards" by no means. Just give me a specifcation sheet and I'll figure my own averages and decide if its cost effective for me or not.
Anyway heres a few places.

Pity about Earth.
