BioFuels Atlas
BioFuels Atlas is an interactive map for comparing biomass feedstocks and biofuels by location. This tool helps users select from and apply biomass data layers to a map, as well as query and download biofuels and feedstock data. The state zoom function summarizes state energy use and infrastructure for traditional and bioenergy power, fuels, and resources. The tool also calculates the biofuels potential for a given area. BioFuels Atlas was developed by the National Renewable Energy Laboratory with funding from the DOE Biomass Program.

Under the Energy Policy Act of 1992 (EPAct) and subsequent regulations, certain vehicle fleets operated by state agencies or alternative fuel providers are required to acquire alternative fuel vehicles. If a fleet has explored available options and cannot meet the requirements, it may request exemptions. This chart shows the number of vehicles exempted from 1997 to 2015. The number of exemptions dropped significantly during the years following the Great Recession of 2008. This is likely due to two factors: (1) the economic downturn has led to fewer vehicle acquisitions, which in turn reduces the AFV-acquisition requirement for covered fleets, so fewer exemptions are needed; and (2) the program offers a number of means to comply, making exemptions mostly unnecessary. In more recent years, the number of exemptions sought increased while the number of vehicles exempted remained relatively low compared to past years.
