Why will renewables not solve anything? What about nuclear?
- bullen 4y agoWind, solar, nuclear and hydro can not be built with electricity at scale, you need coal, oil and gas to mine and melt steel (1500C) and burn lime stone (1500C for 3 hours) for concrete. Also you cannot make food with electricity at scale; tractors, trucks and fertilizers (500C + 200 Bar) need hydrocarbons.
- legulere 4y agoHaber-Bosch does not take hydrocarbons as an input but hydrogen. Methane currently just is a convenient cheap source of that. It will be difficult but there’s nothing fundamental that prevents us from making concrete, steel tractors and trucks without fossil fuels.
