Are batteries cheaper in 5-10 years?

How about large nuclear plants, what are the probabilities of cost overruns and who is insuring that?

These nuclear cost arguments always gloss over the fact that nuclear has no insurance or cleanup costs. Developers will only build plants if the government assumes both of those costs.

Add to that the uncertainty over fuel and the disposal of used fuel, and there's literally no valid cost argument for nuclear.

I'm not anti-nuclear, but the fiscal realities seem insurmountable.

No they don't. The energy you get from your battery costs 10x as much as directly from the panels, but you only get a fraction of your energy from storage.
