> Could you provide some sources? The figure about the proportion of nuclear power is from https://en.wikipedia.org/wiki/World_energy_consumption https://en.wikipedia.org/wiki/World_energy_consumption, the figure "140 years" from https://en.wikipedia.org/wiki/Peak_uranium https://en.wikipedia.org/wiki/Peak_uranium. > Could we really build enough solar and wind at today's level of technology (assuming sufficient economic motivation) without also blowing through our CO2 budget? A back of the envelope calculation suggests that the necessary construction efforts require the emission of a couple of Gt CO2e. For comparison, at the start of 2018 our CO2 budget was 420 Gt (now it's about 320 Gt).
