In its February 2019 Short-Term Energy Outlook (STEO), EIA forecasts that several recent trends in US biofuels markets will continue through 2020. In the STEO, production of fuel ethanol and net imports of biomass-based diesel stay unchanged, while net exports of fuel ethanol decline modestly. Federal mandates and state programs continue to support biofuel consumption through 2020, however, biofuels remain a relatively small share of total US liquid transportation fuels supply.
