Various left-leaning bloggers are defending nuclear power (e.g., Mark Kleiman and Brad DeLong). Besides being vastly cleaner in terms of greenhouse emissions, remember that nuclear power would probably be much safer. For all the hysteria about accidents, no one has ever died here because of nuclear power. Whereas the main alternative -- coal mining -- is the most dangerous job in America. But the literal deaths of coal miners seem to count for less than the fact that a few people would incur a slight and hypothetical risk from nuclear power.
