You realize that the US buys energy from Canada right? The US has no advantage on energy. Even in Europe, building more power capacity is simply a matter of wanting to.
As for Europe, you are right, partially it's a matter of a mindset, however there are objective reasons for expensive energy. France's access to cheap uranium is almost gone. Europe refuses to sign long-term russian gas delivery contracts and are buying spot which costs arm and leg (whatever is left of it). German power plants are shuttered. LNG imported from the US is very expensive.
Some German CEOs (I think Volkswagen if I recall correctly) said recently that Germany offers no competitive advantage these days. I agree.
Where do you think manufacturing will go? Energy is everything.
So yes, energy will be built in Europe and elsewhere.
With your optimism, they would have tackled this problem already.
Texas already paid its price for their lack of investment in traditional generation facilities.
Euro nationalism is so weird to me. I can't think of any metric where the US is doing worst (a part from healthcare and other social issues but those have always been worse in the US). Like in what way do you think that Europe is somehow stronger than the US? By the way this is coming from someone who isn't american, it's just weird that you actually think that Europe's trajectory is somehow towards a thriving future but the US is on its way to fail.
I remember the same doom and gloom and boasting from Europeans back in 2016, but it turns out that even with Trump Europe still didn't manage to outpace economically the US by 2020, or 2024. In fact the gap has widened.
