Modeled after the Defense Advanced Research Projects Agency (DARPA), the Energy Department’s Advanced Research Projects Agency-Energy (ARPA-E) funds game-changing energy technologies that are typically too early for private-sector investment.

From new wind turbine designs and transportation fuels made from bacteria to innovative energy storage solutions and smaller, more efficient semiconductors, ARPA-E projects have the potential to change the way we generate, store and use energy. The program continues to invest in technologies that could radically improve U.S. economic prosperity, national security and environmental well being.
