In our February Short-Term Energy Outlook (STEO), we introduced new forecasts of U.S. production, consumption, and the net of imports less exports of biodiesel, renewable diesel, and other biofuels in the United States. This new breakout highlights our significant forecast for growth in U.S. renewable diesel production. In previous STEO releases, we included a forecast of biomass-based diesel consumption, which combined all production and imports of biodiesel consumed in the United States with imported volumes of renewable diesel, but we did not include domestically produced renewable diesel. By differentiating biodiesel from renewable diesel, these new forecasts provide a more precise accounting of biomass-based diesel.
