The document discusses tools and resources provided by the National Renewable Energy Laboratory (NREL) to help fleet managers transition to alternative fuels. It describes the Alternative Fuels Data Center (AFDC) which provides a station locator, data on waivered vehicles, and tools like the Petroleum Reduction Planning Tool. The AFDC aims to help fleets develop efficient strategies to increase alternative fuel use and identify opportunities to build more alternative fueling stations. The document outlines future enhancements to tools like a FleetAtlas and Fleet Optimization Tool to help fleets optimize their operations and meet federal mandates.
