I think in just the past year or so there's been a sea change in public attitudes on global warming and peak oil, and that things are just now starting to get better. Massive R&D is happening. Whoever the next president will be will probably do quite a lot here. Ditto for big business (GE is putting $2 billion into renewables research, etc.)
I mean, Walmart said they wanted to sell 100 million cfls in 2007 and met that goal by Oct. 2. Dubya (yes, Dubya) just signed a bill banning incandescent light bulbs by 2014.
Yes, these are small steps, but in a few years I think we'll see huge progress.
My view of Kuntsler: He's too gloomy. Yes, it may get bumpy, but increasingly, people do get it.
