Commentators from Greenpeace to the World Bank agree that climate change is an emergency, threatening civilization and life on our planet. Any solution must involve the control of greenhouse gas emissions by phasing out fossil fuels and switching to alternative technologies that do not impair the human habitat while providing the energy we require to function as a species.

This sobering reality has led some prominent observers to re-embrace nuclear energy. Advocates declare it clean, efficient, economical, and safe. In actuality it is none of these. It is expensive and poses grave dangers to our physical and psychological well-being. According to the US Energy Information Agency, the average nuclear power generating cost is about $100 per megawatt-hour. Compare this with $50 per megawatt-hour for solar and $30 to $40 per megawatt-hour for onshore wind. The financial group Lazard recently said that renewable energy costs are now “at or below the marginal cost of conventional generation”—that is, fossil fuels—and much lower than nuclear.
