I cited here that nuclear power, when all things are considered (construction, operation and so on), is about as cheap as it gets except for coal.
We also cited in the other thread that there are new designs which are inherently safe. Physics itself prevents a meltdown. No need to worry about human error because a human could not make it melt if they tried.
It was also noted in the other thread that green energy, while it has its place and can be useful, can come nowhere near meeting the energy needs of the planet.
Natural gas has maybe a 30-50 year horizon till the fuel starts to become too expensive for “cheap” power production. Oil has similar problems.
That leaves coal and nuclear as the major power sources for the future.
Care about global warming? Coal plants are already the major contributor to that and our resident expert on power said that scrubbing CO2 from industrial sized coal power plants is not feasible short of some magic, not-yet-invented technology coming along.
What do you think will happen when India and China add massive power generation capacity using coal (they need lots of power). Think China cares overly much for environmental concerns?
That really leaves nuclear power as the main source of future energy 50+ years out. I may live another 50 years to see it. Kids today certainly will so it is not the unimaginable future. Given the time needed to build a nuclear plant and test some of the new nuclear technologies starting on them right now would not be a bad idea.
