Well, last year or the year before last, Merkel the chancellor of Germany signed a contract to pay utility companies a lot of money for them to keep old generating plants idle but in shape. Else, the plants would be shut down or dismantled.
Earlier in the thread, Musk was quoted as saying we could shut down the oil refineries and have enough power for EVs. Yeah, right!
We've already had that scenario happen on multiple occasions in the U.S., long before solar and wind came along. Why would anyone degrade the system to that point again? We can transition without these power loss scenarios you describe...
In order to "transition without these power loss scenarios", we need ALL of the current plants in shape, and ready to go on a moment notice. That in addition to all the new generating stations.
It can all be done, sure, but it costs money. Nothing is easy and nice like some people think.
Last year, California produced so much solar on some early summer days, it had to pay Arizona to take some. Yes, the power was more than free. It costs California residents money! And of course, in the middle of summer California still does not have enough, and has to buy power.

California invested heavily in solar power. Now there’s so much that other states are sometimes paid to take it - Los Angeles Times
The renewable energy production is not easy to manage. You need almost 100% backup. Imagine if each of our homes needs to have its own battery bank and generator to back up our solar panels.
Well, you don't want to do it, but in order for your utility company to provide that service, they are going to need more money.
It's not going to be cheap, that's all. If you say you don't care about cost, you just want to be green, that's OK with me. Don't say that it is going to cost the same or is cheaper.
