If you look at the beginning of the chart, the price decrease (from $780 to $258 in 2017) over the same four year period was 67%. And for 2023 it was only 24%. So progress has slowed a lot. In 2022 there was even a year-over-year price increase. That's bad news when you want to build massive energy storage systems that can replace power plants.

So what you're trying to say is - "In the past prices fell extremely fast, now they're falling just regular fast".

[cubefox]

I'm saying that prices are falling increasingly more slowly and that using solar+batteries to replace coal, gas and fission power plants will probably not happen.

> using solar+batteries to replace coal, gas and fission power plants will probably not happen

That ship already sailed, many countries are already doing it.

[cubefox]

No, no country is doing it because batteries are far too expensive to replace stable energy sources.

The UK has been burning coal since 1882, and their last coal fired power plant just got it's last delivery of coal [1]

Germany is shutting down it's nukes [2]

Actually, lots of countries are very quickly increasing how much of their energy needs come from green sources [3]

You can't deny reality

Solar and wind energy are impossible without stable energy sources like coal or fission. Solar and wind energy are highly volatile, and battery energy storage is far too expensive.
