CHEYENNE, Wyo. (AP) — Gov. Matt Mead's proposed budget includes $1 million to convert several University of Wyoming vehicles to run on natural gas.

Funding also would go toward building a natural gas filling station on the UW campus in Laramie.

The Wyoming Tribune Eagle reports ( ) Wyoming is moving toward becoming an early adopter of natural gas for vehicle use.

The proposal in Mead's budget comes after Mead joined the governors of Oklahoma, Pennsylvania and Colorado to encourage U.S. automakers to make more natural-gas vehicles.

The states plan to submit a joint plan for buying natural-gas-fired vehicles that are comparable in price to gasoline-powered models.
