West Virginia Gov. Earl Ray Tomblin is proposing eliminating a tax incentive for plug-in electric cars and other alternatively fueled vehicles.

The $7,500 tax credit would remain in place for vehicles that run on natural gas, propane and butane. But it would be phased out in 2017, rather than in 2021 as is currently scheduled.

The tax credit has been used to offset the higher price of plug-in cars. These vehicles tend to be more expensive than comparable models, but require little to no gas and emit almost no pollutants. There is still a federal tax credit for such vehicles.

The governor's office said that if enacted, the legislation introduced on Friday would save the state around $10 million in the next fiscal year.
