Removing triple taxation for resident EV drivers.

HB 145 replaces multiple existing fees for electric vehicles with a single per-kilowatt-hour tax on electricity used to power them. It reduces the annual decal fee for plug-in hybrid vehicles from $200 to $100 and sets a $200 annual fee for all-electric vehicles (previously subject to overlapping taxes). The bill allows EV owners to receive refunds for electricity purchased for vehicle use and requires clear display of the new electricity-based tax. This directly affects Wyoming residents who own electric or plug-in hybrid vehicles by eliminating "triple taxation" on their vehicles and shifting the tax burden to electricity usage.
