I would recommend that you watch this video: [VIDEO] It's quite well researched, and for someone who was also wondering why there is European aversion towards nuclear power, it showed me that it's not that simple. Nuclear power is quite inconvenient and not as magical "free energy" as it seems.

I was curious about new types of nuclear reactors. But, it turns out they still can't deliver what nuclear proponents claim. Sabine Hossenfelder explains it very well: [VIDEO]

[LINK] Or Sabine Hossenfelder's explanation [VIDEO] Current reactors use U235 which is less than 1% of all Uranium on the planet. Don't know about reactors that use other uranium isotopes, but if after 70 years they are still at the design stage, it kind of makes my point. It's just too late to turn that around. The article just overlooks this fundamental problem.
