A new report from the clean tech research firm Pike Research confirms a trend that has been percolating along mainly under the radar: the U.S. Department of Defense is gung ho for clean energy. In an interesting twist, Pike states that “increased access to clean and reliable energy has become a leading priority for the U.S. Department of Defense.” By stressing the reliability of clean energy, rather than focusing on the renewable aspect, Pike effectively steamrolls over any further discussion of whether or not the U.S. should continue to promote oil drilling, at least not for national defense purposes.
