The problem with over-build is that if you count the energy necessary for building the renewable systems (mining, transport, building..) and the losses in distribution, the return of energy could be not so great. This estimation is a depressing reading: https://www.mdpi.com/1996-1073/13/12/3036/htm https://www.mdpi.com/1996-1073/13/12/3036/htm Estimated energy return on energy invested: onshore wind 2.9:1 offshore wind 2.3:1 photovoltaic 1.8:1 concentrated solar power <1:1
