Nuclear power will eventually become our most significant source of green energy. - Inspired by Senator John McCain's comments on nuclear power

If John McCain becomes president, he proposes having 45 new nuclear reactors built in the United States by 2030. He doesn't really see renewable energy happening without nuclear power.

Given that nuclear power produces 20% of the nation's total energy consumption now, this choice of energy is increasingly becoming a hot topic. Why look for new alternative sources of energy, when there's already something in place that could be expanded? It's a logical question, and a source of intense debate in Washington. But it's also of rising interest in the business world.

While T. Boone Pickens plans to spend $10 billion to build the world's largest wind farm, a neighbor of his in Amarillo Texas -- George Chapman -- has announced plans to build two large Evolutionary Power Reactors (EPR) in Amarillo. And though nuclear energy is often heralded as green energy, some environmentalists argue that nuclear waste is neither efficient nor effective in cutting CO2 emissions.
