ORNL Finds New Hydropower Potential at Existing U.S. Dams

Researchers at Oak Ridge National Laboratory and Idaho National Laboratory have identified significant hydropower potential at existing U.S. dams that currently do not generate electricity. Their updated assessment found up to 15.2 terawatt-hours of potential annual generation, enough to supply more than 1.4 million homes. The research uses detailed streamflow, dam, and turbine data to identify sites with the strongest technical potential.

ORNL’s HFIR Reactor Could Speed Up New Nuclear Fuel Testing

Oak Ridge National Laboratory’s High Flux Isotope Reactor could help address a growing bottleneck in nuclear fuel development. HFIR uses an intense neutron flux to test fuels and materials under demanding conditions. Its experiments can produce data on fuel performance, gas release, and fuel-cladding interactions, helping researchers develop new fuels and provide information needed for regulatory qualification.

Germany’s KIT Creates Thin Film System to Turn Waste Heat into Cooling

Researchers at Karlsruhe Institute of Technology (KIT) and the University of Tsukuba have built a heat-driven solid-state cooling system using ultra-thin alloy films. Led by Yi-Ting Hsiau, lead author of the study and doctoral researcher at the IMT, the team produced a 13°C cooling effect using heat instead of electric motors. This breakthrough enables electronics and appliances to cool themselves using their own waste heat.

1 in 7 US Students Study in Solar-Powered Schools

More than 10,800 US K-12 schools now use solar power, serving over 7 million students, according to Generation180. School solar capacity has reached more than 2.4 gigawatts, helping districts reduce energy costs. But battery storage remains rare, with only 155 schools identified as having installed battery systems since 2016.
