@schnedan Small nuclear reactors would be nice, but I think that it would take decades to make them commercially feasible, let alone practical.
As far as alternatives go, I do not see wind or solar power as feasible alternatives, as it is difficult to “scale up” power generation if demand increases (usually gas is used to fill in the gap during peak demands—at least in the US).
I would be loathed to go back to coal. But the world needs a better way to generate energy en masse.
