There are countries which already started transitioning to renewable energies which not only endured long periods of energy independence from renewable sources alone but also already reported energy production surpluses which even led to null and negative energy prices.
Therefore your baseless assertion regarding shutting down nuclear and coal plants seems to be totally made up and completely unfounded.
Can you provide any basis for your assertion, and point out any rational basis for that so-called "energy starvation" scenario?
