ARPA-E, or Advanced Research Projects Agency–Energy is an agency within the United States Department of Energy tasked with funding the research and development of advanced energy technologies. The goal of the agency is to improve U.S. economic prosperity, national security, and environmental well being. ARPA-E typically funds short-term research projects with the potential for a transformative impact. It is inspired by the Defense Advanced Research Projects Agency (DARPA).
The program directors at ARPA-E serve limited terms, in an effort to reduce bureaucracy and bias. Since January 2023, the director is Evelyn Wang.
