The U.S. Energy Information Administration on April 15 released its Annual Energy Outlook 2025 (AEO2025), which includes long-term energy trend projections through 2050. The U.S. Department of Energy, however, is cautioning that the forecasts do not reflect energy policy changes implemented by the Trump Administration.
The EIA is required to produce AEO reports by law. The agency prepares the AEO by using the National Energy Modeling System to project a set of scenarios that, taken together, represent a range of outcomes for the U.S. energy system. In general, the AEO2025 considers laws and regulations that were implemented as of December 2024.
The report includes 11 cases that model a range of assumptions, including the AEO2025 reference case, which assesses how the U.S. energy markets could operate under laws and regulations current as of December 2024 and under historically observed technological growth assumptions. In addition to the reference case, the AEO2025 includes two alternative policy cases and eight core side cases.

The cases include data on a wide range of energy types, including biofuels. The reference case predicts E85 use will decline by 3.5% between 2024 and 2050. Total ethanol blending is expected to fall by 1.3%, with biodiesel use falling 3.5% and renewable diesel and gasoline consumption increasing 2.8% over the same time period.
Under the reference case, the total U.S. supply of ethanol is expected to fall by 1.7%, with corn ethanol supply falling by 0.7%, cellulosic ethanol supply falling by 0.1% and net imports of ethanol increasing by 3.2% through 2050.
The AEO2025 includes a case that assumes high oil prices. Under the assumptions of that case, E85 use falls by 6.4%, total ethanol use calls by 1.8%, biodiesel use falls by 1.1%, and renewable diesel and gasoline use expands by 4.8%.

Under the high oil prices case, total supply of ethanol would fall by 1.8%, with the supply of corn ethanol falling by 0.7%, the supply of cellulosic ethanol falling by 100% and net imports increasing by 3.2%.
The DOE issued a statement cautioning that many of the policy assumptions included in the AEO2025 have already been reversed by the Trump administration. “Today’s report from EIA reflects the disastrous path for American energy production under the Biden administration – a path that was soundly rejected by the American people last November,” said Andrea Woods, a DOE spokesperson. “Under President Trump’s leadership, the Department of Energy is charting a new way forward for America’s energy future that promotes greater consumer choice, ensures the U.S. has the power to lead the world in AI development and expands economic growth fueled by American energy dominance. By unleashing energy that is affordable, reliable, and secure, this administration is ensuring America’s future is marked by energy growth and abundance – not scarcity.”
The AEO2025 data is available on the EIA website.
Valero Energy Corp. released Q1 financial results on April 24, reporting that a tough margin environment negatively impacted the company’s renewable diesel operations during the three-month period. Valero’s ethanol segment was profitable.
Mammoet on April 23 announced that it will be implementing HVO fuel across the Netherlands, U.K. and Canada. The investment in HVO was driven by higher demand from lower carbon solutions from the company’s customers.
On April 23, the Advanced Biofuels Association (ABFA) met with officials in the U.S. EPA to convey the vital importance of domestic biofuel production to the Trump-Vance administration’s energy dominance policy agenda.
Aemetis Inc. on April 23 announced that its subsidiary in India, Universal Biofuels, has been working with the U.S. government to support the success of American interests in India. U.S. Consul General Jennifer Larson recently toured the facility.
