The United States Secretary of Energy Jennifer M. Granholm announced the winners of the 2021 U.S. Department of Energy (DOE) Solar Decathlon, a competition that challenges architecture and engineering college students from around the world to design and construct high-performance buildings powered by renewable energy. 72 competing teams hailed from 12 countries and designed energy-efficient residential and commercial spaces, nine of which were constructed and presented in the Solar Decathlon Virtual Village on the National Mall, a first of its kind, in Washington, D.C.
