From 2011 to 2015 the U.S. military nearly increased its renewable power generation by 100 percent while the nation’s economy added merely 2.6 percent of renewable power generation. With continued growth in renewables and further investment in the U.S. Defense Advanced Research Projects Agency, which engages in cutting edge experimental technologies, the United States could maintain a competitive advantage with its allies in NATO and the EU as well as with rivals like China who, according to Dr. Alexander V. Mirtchev, is prepared to be the world’s leading producer and consumer of alternative energy technology in the world. Mirtchev offers a variety of valuable lessons for Defense Department budget planners through his book, The Prologue: The Alternative Energy Megatrend in the Age of Great Power Competition. The book analyzes major shifts in renewable energy sources in various sectors including continued investments in alternative energy throughout the Defense Department.
