In the GW range batteries aren’t a great storage solution. At that point you’re basically sitting on a bomb with that much chemical energy storage. Before you get into all the losses from having to temperature stabilize the system. The most efficient/preferred solution is an artificial reservoir. Pump water uphill when you have excess power, run the generator when you need power.
Dams also aren’t permanent structures. There’s been a growing concern for awhile now about dams being managed by financial entities. Because local governments couldn’t/wouldn’t run them after their expected lifespan ran out in the 80s/90s they were seen as a reliable investment. Especially if you cut costs. On a dam basically the only costs to cut are maintenance.
Dams being decommissioned instead of failing is a better strategy.
Yuppies are weird because it was originally just a way to keep them in the news (“new movement! new group! news at 11!”) and be ridiculous. They got the DoD to sign a contract about exactly how high they were permitted to levitate the Pentagon.
And then it had it’s own Eternal September moment. But everything seems to.
