Solar has been on the verge of transforming the world for at least 40 years now.
I ain’t holding my breath.
That last chart is really cool. It looks like solar will cost less than $0 per megawatt in 2039. So put up a solar plant and you don’t even have to sell any electricity to make millions!
BAM!
And there you have it.
The bottom line is that generation ceases at night, and is reduced sharply when overcast. People still use electricity at those times. “Grid parity” would seem to require you have some means of overcoming this.
The problem seems to be storage or lack of capable batteries.
