I'm definitely all for some decentralization, but our power grid would need to be overhauled drastically to support solar/wind at a large scale. A cloud going over a bunch of solar panels, for example, is a massive engineering problem and can bring down a grid temporarily.

Our tech just isn't ready to go full steam ahead into renewables. Storage tech will be a large step closer, but remember the scale we're talking about. I understand that investing in renewables invests in research, but I fail to see how nuclear isn't the off the shelf answer.

Cheap - sustainable - steady power - thorium reactors are even renewable. Modern designs and computers make nuclear disasters far less likely (to the point where it's not really a valid concern). Nuclear waste isn't even as big an issue as people believe. Most of the waste can just decay on-site. The Boring Truth About Nuclear Waste
