Wht do we need to make it "survive"? It can be preserved without wasting or energy.

For that matter: why does it need to "survive"? Just because it's old doesn't mean it's valuable and needs to be preserved.

None of your points have anything to do with my response. Moving the goalposts shows that you aren't capable of thinking clearly about the issue and your ad hominems speak even less about your character.

The energy was going to waste, a heritage site was preserved, no co2 was released, they were unable to sell the power to the grid.

Keep raging at windmills that generate 0.1% of global emissions if it makes you feel like a hero. It won't solve anything.
