Wyoming provides power to quite a few states [1] and has the highest potential for wind power [2][3]. Wind power has been growing very fast. The grid I am on also has a massive solar farm but I do not have stats on how much it produces. Probably not much right now as it has been snowing all day.
They can probably get away with saying that since about the only demand for EV's would be in Jackson Hole. Most of the state is rural and most ranches and farms need powerful trucks that can haul large loads long distances. Equivalent EV trucks do not yet exist to replace Ford F450/550/650 and Chevy 5500/6500.

The playbook for obscure republican politicians is to flip the bird at something and get some rah-rah from the base. Plus, sometimes hidden in the pandering is some actual problem identification.
1. Someone who doesn't hold a particular position absurd to make a sarcastic point.
2. Dogwhistle to the fascists, kleptocrats, and ideologues. It maybe "tilting at windmills", but it's bluster "to impress the ladies".
3. An attempt to raise a proposal so extreme in order to gather press coverage.
Also, "more electric vehicles will require massive amounts of new power generation in order to sustain the misadventure of electric vehicles" strikes me as a little silly, since isn't "oil and gas" a great way to create electricity for said vehicles?
