On a deaths per joule comparison nuclear power wins over them all by a large margin. Do you think that people don't fall from windmills and rooftop solar panels? People die.
Also, people in Fukushima got more radiation by flying from the area than if they stayed. Chernobyl was barely a first generation reactor, it didn't have modern safety features like a containment dome. The answer to this problem is not to stop building nuclear power plants but to build more so that we can afford to decommission power plants like those at Fukushima.
Japan shut down all their nuclear power plants for a while but were forced to restart them. This is because without nuclear power they had to resort to dirty, unsafe, and expensive coal. Wind, solar, and tidal power would cost us more in money and lives then even building more Chernobyl type power plants.
Thankfully we don't have to build another Chernobyl, Fukushima, or Three Mile Island to keep the lights on. We can build fourth generation nuclear power, reactors that are safer, cheaper, and more reliable than even the already very safe, cheap, and reliable first and second generation reactors that caused us so much panic.
At a minimum we should at least have some government funded research in nuclear power like we have government funded research in wind, solar, and tidal. We have much to learn on nuclear power, and claiming we cannot harness that power safely is like claiming we should not invest in Tesla motors because the Model T and Pinto were unsafe. A modern nuclear reactor would not be built like those at Fukushima.
We can build much better nuclear power plants but we've held ourselves back because of failures of completely unrelated designs. Failures that, BTW, involved very little cost in lives and cleanup when compared to the alternatives.
