The U.S. Army has embarked on an ambitious $7 billion series of utility-scale renewable energy projects. The new program involves building twenty utility-scale renewable energy installations that rely on a mix of solar, wind, geothermal, and biomass power. The installations will be constructed on land owned by the Department of Defense, at Army bases throughout the U.S. The program calls for the Army to use its land as equity to leverage about $7 billion in private investment for the twenty projects.
