>Navy and Marine Corps brass, accompanied by green energy executives, showcased the energy-harnessing knee braces and other innovations at a renewable energy demonstration at Twentynine Palms Marine Corps base, one of many such events that have taken place at military bases across the country as part of the Defense Department's unprecedented shift away from fossil fuels under the Obama administration. The Pentagon has invested millions over the past decade into everything from hybrid electric ships to wind turbines.
>While a growing number of military leaders have declared global warming a national security threat, the strategy clashes with President-elect Donald Trump's vow to end policies that "undermine" fossil fuel producers. Trump has a chosen a Cabinet with climate change skeptics, though his pick for defense secretary, retired Marine Gen.
