EV Ownership in Wyoming
Wyoming has very low EV adoption due to sparse population, extreme climate, and a fossil fuel economy. Cheyenne and Casper have the most activity. The state's low electricity rates are a financial positive for EV owners.
Wyoming has no state EV incentive. Federal incentives apply. Rocky Mountain Power offers standard rate structures with limited EV programs. The state's oil and gas industry makes EV policy progress slow.
I-80 has DCFC coverage at Cheyenne, Laramie, and Rawlins, but gaps exist. I-25 north to Casper is manageable. Going off major interstates in Wyoming is a real range planning challenge.
Wyoming is the largest coal-producing state, but also a significant wind producer (~30% of generation). Rocky Mountain Power's wind integration is growing, and the grid is cleaner than the coal production image suggests.
