Nuclear energy is the only energy source that can fully replace fossil fuels. Nuclear is also the safest, cleanest and least-cost source. Nuclear fuel is inexhaustible: we will never run out of uranium or thorium. Without the power of nuclear energy, the dual risk of global warming and resource depletion driven by unmovable economic reality continues to grow, potentially leading to the ultimate collapse of modern civilization. We must work to discard our unjustified, uninformed aversion to nuclear technology. Popular acceptance of nuclear technology is crucial, possible and beneficial.
