Fascinating new EIA data

South Dakota produced 110% of its electricity demand with just Wind-Water-Solar for the full year Oct 1 '23-Sep 30 '24

77.5% Wind 30.1% Water 2.2% Solar

Also produced 16.8% gas, 11.7% coal

So SD produced 138% of demand, exporting 38%

It's certainly good, but I think it'd be better if we had some additional clean way of covering our base load. Like nuclear.

Renewables + storage (batteries, etc.) can be more than enough. And you can get that in a much lower cost, at a much faster time than nuclear.
