That translates to 12 grames of Co2<sup>e</sup> per KwH, which is equal to wind (solar being 20+). So less or cleaner conrete would help to make that impact even lower. But these sites are also heavily over engineered.

We use concrete because it is cheap and easy to use. There are better materials out there for a long time, centuries even. But the problem is always price or labour. So without a carbon tax, cement will be able to externalize it's true costs towards the environment.

These ideas are also meant for the "developed" world. Large central fossil feul burning is on the way out. Local wind and solar is the future. The benefits of centralized energy production in terms of economies of scale make less sense in a renewable world.

Or, like you mentioned, we just leave this abusive relationship...
Concrete will always be useful for certain things, like foundations, elevator shafts. But it should not be the ubiquitous building material that it is.
