Can renewables power everything though? Seems unlikely, we'd need 50% renewables + all the batteries we can make forever, and 50% nuclear to replace coal, gas, and oil. Average EU human uses 4kW of energy 24/7, including everything they eat, buy, heat, move etc. Assuming we move all use of engines to electricity and generate renewable power so don't waste 50% heating water in power stations, and get it down to 2kW, to store that power for just a day would be an electric car sized battery for every human.
