"with wind the single-biggest contributor.... Power production costs have declined “by almost half” .... And the clean energy sector has created 50,000 new jobs.... Ask me what was the impact on the electricity sector in Uruguay after this tragic war in Europe — zero."

But the issue is you still need something for when the sun isn't shining like what happens every night, and when the wind isn't blowing, which can also happen at night. What will power everything during that time? Nuclear can be the backbone that keeps things running when renewables aren't keeping up with demand. Sadly we can't fully rely on renewables, and between having gas and coal as the backup or nuclear as the backup, I'd prefer a billion times nuclear over the other option

Batteries my guy. Batteries. You charge up your batteries by producing more electricity than you would need during the day, that keeps the lights on (so to speak) during the night.

Did you ever calculate the amount of battery capacity you'd need for, let's say a week in winter?
