It's nice to call it "politics, ignorance and greed" but those three are just "Capitalism".

Our system is doing exactly what it is designed to do. Nuclear reactors were never profitable compared to coal or gas, so it never succeeded in strongly capitalist societies, only seeing great success in socialist economies where the people can invest outside of a profit motive.

It's actually quite funny that socialism is saving the day. The mega-capitalist countries turned their backs on nuclear and solar because they were less profitable than gas and coal. But socialist China invested anyway, and now China is mass producing nuclear reactors and every layer of the solar stack. China produces 50% of all nuclear reactors, 90% of all solar panels, 90% of all battery systems for solar storage.

Now that a socialism-based society has proven market viability, suddenly the greedy capitalists want in. But they're decades behind and don't have the private debt appetite to compete.

Womp womp... At least someone is leading the energy revolution.
