Also consider that we will be able to recycle the materials used so the extraction should level off to only supplying potential market expansion and loss.
Is iron mining and refining as toxic as, say, lithium? Particularly when adjusted for how much extra mining you have to do for a particular amount of end product?
Just throwing out factors to consider like you are doing (and I just did) is not very useful unless you also include some numbers for scale. Do some research and share.
CCGT turbines are a bit different in that they have turbine first, and then the same steam boiler to turbine setup.
That is why I ask. All generation from mechanical sources needs generators, they need control circuitry. Steam plants need boilers, cooling towers and what not.
Just wanted to point out that singularly focusing on "hurr durr renewables need to dig stuff out from the ground and not made using pixie-dust" is quite the irrelevant take since the entire energy generation industry shares so much complexity, no matter the source of energy.
