I looked at that site, but the data here is hard to verify, and the methodology is a bit unclear. E.g., coal energy only has a coal material flow, the wind turbine only a steel material flow. I'm not even sure if that means that the turbine has a life expectancy of so many GW and then is considered evaporated. I suppose coal plans are made of cotton candy, or the material per GWh is negligible ? Trying to figure this out, a nuclear plant might have 1GW capacity and a lifetime of 30 years, so ≈260,000 hours. [1] seems to suggest a plant would need 40,000t of steel, or about 0.16t steel/GWh over the lifetime, with coal plans using over twice that. My math might be off, or the assumptions might be wrong.
