The U.S. military is the world's biggest consumer of energy, and Katherine Hammack has spent six years working to make it more energy-efficient. In another part of the U.S. government, Ellen Williams is building bridges between energy ideas and their manifestation on the market. She tells about that and offers advice for women on moving up in the energy field.
