A pump at an alternative fueling station that provides fuel other than gasoline is shown in San Diego, California January 8, 2015. With gas pump prices lingering near their lowest levels in five years, greener, cleaner alternative fuels are taking a hit. Makers of biodiesel, a fuel made from vegetable oil or animal fats, are slashing prices and margins in a bid to stay competitive with the price of diesel fuel, which is down more than 20 percent from a year ago.
