Premise 1: Climate change is real.
Premise 2: To avert catastrophe we must either drastically reduce our use of fossil fuel energy or replace it with carbon-free energy, or both.
Premise 3: The worldwide demand for energy is going to grow, not shrink.
Premise 4: Solar, wind, thermal, etc., will never meet that demand.
Premise 5: Even if “green” technologies could meet the demand, their manufacture requires more fossil fuel energy than they produce.
Conclusion: Therefore the only possible way to avert catastrophic climate change is to employ nuclear power on a large scale.
To do this will require . . .
1. Fail-safe reactor designs.
2. Safe management of nuclear waste.
3. Development of advanced reactors that can use the waste from older reactors as fuel.
