I mean batteries might work! My problems with that approach is that: 1) Batteries are in everything. If we want to go from fossil fuels to renewables + batteries, at the same time as we go from ICE cars to BEVs, that's going to be a lot of batteries. Does the world have enough raw materials and batteries to do that? Back of the envelope: My country consumes 77 TWh yearly or about 212 GWh per day (assuming it is evenly distributed). To cover day-to-night cycle, would we need 100 to 150 GWh of batteries? That's a lot of batteries (seem like yearly production of whole world but I can't find good source) and 10 % of our GDP in current battery prices. 2) If we're saying "renewables are cheaper", are we really adding the cost of storage?
