You can have 100% renewable energy. You can't realistically produce cement or steel without using and exhausting large amounts of CO2. This has to be addressed, even if it costs energy (which, as we agreed, can be 100% carbon-neutral).
- adgjlsfhk1 10mo agothere is no world in which it is cheaper to produce steel releasing CO2 and recapturing than fobbing off recapture until later. the thermodynamics just don't work.
- Thorrez 10mo agoSorry, I don't understand. You're comparing 2 things. For the 2nd thing, are you including the cost of later recapture or not? If you're not including the cost of later recapture, then it's not a fair comparison. If you are including the cost of later recapture, why is it cheaper to recapture later than to do so immediately?
