Iowa is working with five other states to study the availability of alternative fuel along Interstate 80, reports Radio Iowa. A federal grant will help determine where electric vehicles can be charged and where compressed natural gas is available. Drivers of electric vehicles are said to suffer from “range anxiety,” as there are long stretches of road where there are no charging or fill stations. For now, Iowa only has three of the DC-3, or fast-charge, stations, in Council Bluffs, Des Moines and Coralville, while Tesla has some stations for its own vehicles.
