U.S. biodiesel use increases outside of the transportation sector
A small but increasing amount of biodiesel in the United States is consumed in the residential, commercial, and electric power sectors, according to new estimates now published in our State Energy Data System. Previously, we allocated all U.S. biodiesel consumption to the transportation sector, where the vast majority of biodiesel is consumed.
U.S. nuclear generators import nearly all the uranium concentrate they use
In 2023, U.S. nuclear generators used 32 million pounds of imported uranium concentrate (U3O8) and only 0.05 million pounds of domestically produced U3O8. Imports accounted for 99% of the U3O8 they used in 2023 to make nuclear fuel. Foreign producers predominantly supply the U.S. front-end nuclear fuel cycle, but federal policies have been implemented recently to build out the domestic U.S. nuclear fuel supply chain. The U.S. Department of Energy (DOE) recently received $2.7 billion in congressional funding to help revive domestic fuel production for commercial nuclear power plants.
