No I’m looking at flows. Look at the change in % of fossil fuels to other energy sources over time. When Nuclear goes up, fossil fuels goes down, when it goes down fossil fuels go up. When solar/wind go up, fossil fuels are untouched.

Also, again - PVs can only replace grid energy (well not even then because we don’t have an answer for storage & there’s nothing being built anytime soon & we don’t really have anything realistic in the R&D pipeline). Plenty of energy use in the production of PVs is off-grid and we’re doing terribly on replacing that. PVs manufacturing isn’t going to be net-0 for a very very very long time.
- pfdietz 3y ago> PVs can only replace grid energy PV can replace anything. The question is cost. At historical experience rates, PV energy will be under $0.01/kWh by the time the world is solar powered. Resistive heat using this would be comparable in cost to combustion of currently cheap US natural gas, perhaps even cheaper. It would literally be cheaper to use that to heat up a large mass of rock and use that to make steam to make power, than it would be to make that steam (and then generate power) with a nuclear reactor instead.
