Hydroelectric and nuclear power are the only reliable, non-polluting, and cost effective sources of large scale power. Uranium (U) and Plutonium (Pu) yield 3 million times more energy than the same quantity of coal (e.g., 1 gram of U or Pu = 3,000 kg of coal)!
Given the potential hazards, nuclear energy may not be our first choice; but it will likely be forced upon us by necessity as we move away from fossil fuels (assuming there is no new breakthrough in energy technology). Rather than tilting at wind turbines, our time and money would be better spent improving the safety of nuclear power and resolving the question of nuclear waste disposal.
