"What if we hadn't started using computers because they were more expensive than typewriters?"
Secretary of the Navy Mabus announced that the Navy has made a commitment to get 50% of its energy from renewable sources, like biofuels, solar and wind, by 2025.
Mabus pointed out that the Navy has always led in pioneering new sources of fuel, whether it was from moving from sail to coal in the 1850s, to oil in the 20th century, and nuclear energy in the 1950s. "Every time, there were doubters and naysayers," he said forcefully."Every time. And every single time, they were wrong and they will be wrong again this time."
