At the inaugural 2013 Convenience Store News Alternative Fuels Summit, sponsored by Growth Energy, the publishers reported on its 2013 Motor Fuels Study. A major finding is that retailers want to sell alternative fuels. Among respondents, 43% currently offer alternative fuels. However, in five years, 51% expect to do so. Only 7% of retailers surveyed currently sell natural gas at the pump, but that number is expected to rise to 28% by 2018.
