The key word there is "hydro". We've already largely maxed out our hydro capabilities, so it's off the table as far as new power generation goes.

The other huge problem with hydro is that although there are minimal direct carbon emissions, the environmental impact is still pretty hefty. Hydro always requires huge amounts of wilderness to be submerged, and the millions of trees that get killed in the process not only stop sequestering CO2, but they rot and release enormous amounts of CO2. That's to say nothing of the fact that any migratory organism that gets killed or injured going through a hydroelectric turbine gets pushed to local extinction.

What do you think the environmental impact of massive batteries are??

Incidentally, geothermal energy is basically natural nuclear energy, only it is far far far far less abundant and far more expensive and technically difficult to exploit.

You need to stop parroting what lefty propagandists tell you, and actually use that little thing between your ears (that's not your nose).
