If the issue is cutting CO2 with a power generating solution that’s highly, highly reliable, renewables like solar+wind have an uphill battle to fight. Their load factor is abysmally low, and storage tech at scale just isn’t here to sustain daily demand for 72 hrs. Supplementing with hydro instead of gas/coal to pick up the slack probably implies some massive “three-gorges” style damming projects. How feasible that is varies by region. What do you think about the feasibility of building that much hydro capacity in a way that can sustain Europe’s daily need for three days running? If you had that, why even bother with solar+wind except maybe as localized off-grid solutions? Somewhere out there is also a question of hardening generating capacity against kinetic attack, but that’s a whole separate thing. I only think of it because dams seem pretty vulnerable, especially massive ones.
