"Sustainable Energy - without the hot air" [1] suggests renewables don't stand a chance at displacing conventional power generation without radical efficiency gains across the board and massive investment in infrastructure. They are not ready to drop in at massive scale.

As for Fukushima: I can't find a single source suggesting there is any danger short of eating fish caught right in front of the facility, which would indeed be a bad idea.
