We're not speaking about households. We're speaking about huge geographic areas that would have to redo their grids completely. You truly have no idea what you're even posting about.
It works differently in other countries. The definition of baseload is: "Base load power sources are those plants which can generate dependable power to consistently meet demand". That's it. It might be variable or constant, it doesn't matter.
It is NOT an easy problem. Energy storage might well be easier, and there's even a good prospective technology for that (vanadium flow batteries).
As I pointed out: baseload is adjusted every week or every few weeks, so the plants can be used at optimum. But baseload is not changing during the time of the day.
Dude, I pointed you at a specific example. Here's the dashboard for the generation in France: https://clients.rte-france.com... - notice the "Generation forecast" graph. It shows that the generation changes drastically throughout the day, even though France uses mostly nuclear power plants.
Is exporting now a bad thing?
Yes, it is. Because it implies that somebody else does the balancing.
So no, current grid can not cope with the variability of renewable sources.
So please, stop showing your complete ignorance of actual issues.
First of all, for starters: it is impossible that a offshore wind farm does not produce energy fro two days
It's possible. It doesn't happen _often_, but it happens at least one time every year on the Eastern coast of the US. Mostly during big storms when turbines must be turned off.
This is the case RIGHT NOW, but not when we have a 100% renewable grid.
And a pony. Don't forget a pony.
Denmark, Portugal and other postage-stamp-sized countries are simply not interesting - they can overbuild power transmission infrastructure and buy electricity from neighbors.
Now imagine that a blowhard greenpeace hippies closed one power plant and installed wind turbines around the one of the cities. What is going to happen if a sudden anticyclone causes a windless weather over a large region? Answer: whoops, your the power line between cities has just melted, even though the other power plant had enough capacity to handle the load.
And this is not a theory, such things might happen any time in Germany now. Its grid is overstressed because renewable energy generation and consumption are quite often not correlated.
