Nuclear is a dead end that is best forgotten - its time to give up on dreams from the 1950s that went sour decades ago.

We can power the whole world with renewables and dispense with polluting power sources based on extraction of finite resources.

All our power needs can be met from 3% of the world's desert areas - I'm sure these 'fragile ecosystems" could handle that if necessary (of course, we'll actually do so much distributed, small scale generation that this won't be necessary).

We are talking about the facts here, and I don't have any special knowledge of the facts. I find some experts more convincing than others. I just want to take this opportunity to reiterate my one and only certainty. The Energy Crisis is an engineering problem. The route to the correct solution lies in a vigorous open well-funded investigation of the facts by teams of engineers and scientists with good mathematical skills. TheOilDrum is a fantastic proof of what can be done, even without the "well-funded". I was slightly encouraged by Eric Schmidt's talk.
