Yes my bad, not cement, it's not mortar but concrete, 150-300m^3 of concrete per 2MW windmill.

Yes my bad, not cement, it's not mortar but concrete, 150-300m^3 of concrete per 2MW windmill.
- jhgb 6y agoWindmills didn't have 2MW power output either.
- Kuinox 6y agoDid you actually watched the video ? "Turbines in the 1 to 2 MW range typically use 130 to 240 m3 of concrete for the foundations". https://www.ge.com/renewableenergy/wind-energy/onshore-wind/2mw-platform https://www.ge.com/renewableenergy/wind-energy/onshore-wind/...
- jhgb 6y agoYou were talking about windmills a moment ago, now you're talking about turbines? You're very confusing.
- Kuinox 6y agoSo, you obviously didnt watched the video. Yes my bad, in my native language windmill and wind turbine are the same word. I was talking about wind turbines, as you can see in the video.
- jhgb 6y agoIn that case, 200 cubic meters amount to around 80 tonnes of CO2 emissions. That's around 80 MWh worth of coal electricity, which a 2 MW wind turbine running at a 30% CF offsets in around a week. So a complete non-issue.
- Kuinox 6y agoGP tried to make a point about CO2 emitted by cement which is invalid because wind turbine need a lot more of concrete per MW.
- natch 6y agoI don't think the numbers for cement use by nuclear include the cement used for the sarcophagus at the end of the lifetime. But they should, if you want to talk about validity.
- Kuinox 6y ago> I don't think. They do.
- natch 6y agoSource? I doubt it.
- Kuinox 6y agoInstead of doubting, and thinking based belief, maybe you should verify ? https://en.wikipedia.org/wiki/Life-cycle_greenhouse_gas_emissions_of_energy_sources#Nuclear_life-cycle_breakdown_sample https://en.wikipedia.org/wiki/Life-cycle_greenhouse_gas_emis... The wikpedia source give a breakdown of how the CO2 per kwh is calculated for a Sweden nuclear plant, it take everything in account, the building, nuclear fuel processing and storage, and even the electricity distribution to the grid. Then, no sarcophagus are built at the end of the nplant timelife, they built ont for chernobyl, that all.
