I don't see any way electricity could fall anywhere near that much in 20 years. For that to happen, we either need a revolutionary decrease in the price of nuclear power, a radical improvement in the price of dependable renewable energy (probably involving a lot of batteries) or some hard AI takeoff that makes EVERYTHING cheaper.

Keep in mind that most countries are trying to electrify most parts of the economy, so we not only need to decarbonize the current electrical supply, but possibly 2-3 times that, if we are to replace NG for heating, steel and chemical industries, fertilizers and so on.

Keep in mind that even if the technology for producing windmills and batteries go down a lot, we still need a lot of new mining capacity to even have enough raw materials to produce those items. That alone could take 10-15 years to build out.

It's actually very likely.

As long as you only consume it while the Sun is shinning, at the place of generation. This set of restrictions is allowing enough for a surprisingly large set of industrial applications (anything where energy costs are larger than capital ones).

In fact, we are not far from that. Solar is already a few times cheaper than the grid energy on those conditions.

My post was that electricity prices would come back by a factor of 10 or more. While that was qualified by "not Antarctic winter", it did not say that it would be only while the sun was shining, either.

That was what I objected to.

And if the average price falls by 90%, there number of industrial application where it would make sense to consume only part of the day, drops by a lot.
