People are so focused on $$ when it comes to (green or other) energy. The real problem is not $$ but Joules. Building any type of a power plant costs energy itself, and unfortunately unlike capital, which is just a concept that you can argue with and win, there is absolutely no arguing with physics: https://en.wikipedia.org/wiki/Energy_return_on_investment#ER...

The energy amortisation time of green power generators (the time it takes to pay back the Joules) is orders of magnitude higher than any dirty energy. This problem is well visible once you count all of the world's energy usage and just plot it. The rollout is anything but fast: https://en.wikipedia.org/wiki/World_energy_consumption

Nuclear is the answer.

Not convinced.

I’m using utility solar for about 20% of my electricity needs, precisely to experience what’s claimed. Average cost is 50% above regular sourcing, and rising significantly.

What is the significance of this?

Is that a price of power rise or a price of transmission rise?

Nuclear is the answer.

You could start planning now and you would be lucky to get shovels in the ground by 2035.
