content: Quote from: Circlotron on October 25, 2015, 07:50:49 amWild back of the envelope order-of-magnitude guestimate without looking anything up: 100kWh. That's based on 250eV per copper atom (allowing for the huge inefficiency of the whole process, but perhaps I'm still being conservative).Quote from: Circlotron on October 25, 2015, 07:50:49 amIn terms of raw energy cost, aluminium is a lot more damaging AFAIK. Australia is one of the main producers and exporters of Al ore, and all the Aussie Al production is powered by the dirtiest modern fuel, coal. The bulk of our Al ore export is to China and that fares no better (we also export coal to be burnt in China).

content: Quote from: T3sl4co1l on October 25, 2015, 06:09:09 pmIt's a lot more than that for sure. Not talking about just the energetics of the chemistry but the actual energy cost per atom from mining through to you having a piece of aluminium ready to use in your hands.
