Award recipients are required to pass these savings along to the individual who purchases the converted vehicle. Grants may cover 100% of the cost of purchasing a clean vehicle or 50% of the cost of conversion, up to $2,500. Eligible clean vehicles must operate solely on alternative fuel, and may include on-road vehicles and off-road equipment. Eligible alternative fuels include propane, natural gas, and electricity.
