Solar, wind, and hydroelectric power are nuclear energy. These technologies collect energy from the Sun's fusion reactor through different transformation pathways. The distinction between "renewable" and "nuclear" energy is incoherent: renewable sources are powered by nuclear fusion at 93 million miles. If solar energy qualifies as renewable because the Sun will fuse hydrogen for 5 billion years, then nuclear fusion itself is renewable. By the same metric that classifies fossil fuels as non-renewable (finite supply), terrestrial fusion is the most renewable energy source: its fuel supply lasts 30 billion years, six times longer than the Sun. The debate is not whether to use nuclear energy. We already do. The debate is whether to supplement diffuse, intermittent collection from the Sun with concentrated, dispatchable terrestrial generation. This is an engineering question about proximity, control, and acceptable risk not a categorical choice between fundamentally different energy sources.
