The U.S. Department of Energy, the National Renewable Energy Laboratory, and Argonne National Laboratory have released a new study that finds the United States has the potential to reduce petroleum use and greenhouse gas (GHG) emissions in the transportation sector by more than 80% by 2050.
The (TEF) study includes nine reports that identify possible paths to a low-carbon, low-petroleum future in the U.S. transportation sector, which accounts for 71% of total U.S. petroleum consumption and 33% of U.S. carbon emissions.
The TEF study finds that there is no single “silver bullet” solution for cutting transportation-related energy consumption and GHG emissions. Achieving this goal will require an approach that combines strategies to:
- increase fuel economy for all types of vehicles;
- reduce transportation demand through smart growth strategies, increased use of mass transit, tele-working, tele-shopping, carpooling, and improvement of vehicle performance and freight service; and
- expand use of low-carbon fuels, including biofuels, electricity, and hydrogen.
