No, there are no blackouts because there is not shortage and plenty of capacity.
Consumer prices for energy are less subsidized and taxed more in the EU. So, people tend to care about not wasting it a bit more than in the US.
The US is really good at making cost somebody else's problem. That's why it has blackouts. Because ultimately it is a problem that needs solving. And that takes money.
America doesn’t really have regular blackouts. Most Americans have never experienced one beyond the occasional tree knocking down a utility line.
We can cherry pick a couple of incidents (California wildfire with rural town blackouts and Texas’s winter weather failure), but you could do the same for Europe as well.
The higher costs do cause more judicious use of electricity than the states. Electricity rates aren’t subsidized in the states, rather electricity rates subsidized some of the dumber projects and mismanagement.
Again, even in those states, the rolling blackouts are really rare, or correspond to certain events (often both, most people outside of California don’t realize 5e blackouts didn’t apply to La/Bay Area where most Californians lived, and only rural towns were effected).
We can also cherry pick European blackouts from https://en.wikipedia.org/wiki/List_of_major_power_outages if fairness is desired. If we want to go by frequency, Australia seems to be the worst developed country for blackouts, but their infrastructure is more spread out.
