From The Wall Street Journal:
Safe fission power is our future -- if regulators allow it.
After the Internet, the next big thing will be cheap and clean energy. Coal, oil and gas pollute and are increasingly expensive: We need alternatives. Because nuclear energy (stored among particles inside atoms) is millions of times more dense than chemical energy (stored among atoms in molecules), nuclear reactors belong high on our long list of energy alternatives.
Nuclear energy is released during fission and fusion. During fission, large elements like uranium are split into smaller elements. During fusion, small elements like hydrogen are combined into larger elements. These two processes have occurred naturally since the beginning of time -- 13.7 billion years. The Earth is warmed naturally by its own nuclear fission reactors within and also by the sun, that big nuclear fusion reactor.
