"A clean-energy economy, I think, is the future,” according to 75th U.S. Secretary of the Navy Ray Mabus, who leads America’s Navy and Marine Corps. One of the world’s largest fuel consumers, the Navy has committed to obtaining 50 percent of its total energy consumption from alternative sources by 2020. Mabus said he's “absolutely convinced” that goal will be met. “Now is exactly the time that we have to do this,” Mabus said. “A tightening budget situation makes it even more urgent, even more critical.” He discussed concerns about sea level rise in the Pacific, melting ice in the Arctic and the Navy’s power to help move the market into a lower carbon future. "We don't pick and choose what we protect right now – we protect the world," Mabus said. This conversation covers the Navy’s outlook on the road toward a cleaner energy economy, as well as its political challenges. “I have been sort of honored by the push back," Mabus said about the Navy’s move to use biofuels. "What it says to me is that what we're doing is working."
