The "cement" in concrete is a chemical.

It probably won't be Portland cement which is made by heating certain rocks to 1,450 °C, usually in a coal fired kiln.

The resulting coal ash is itself a significant constituent of that cement.

Solar and wind power are not sustainable if they have to make their own concrete and metal.
