U.S. Navy: Computers were more costly than typewriters Featured
Notes: Here's a longer excerpt from Climate Progress.
"U.S. Secretary of the Navy Ray Mabus. . . emphasized that 'drilling alone will never solve our national security concerns over foreign oil.' Mabus went on to announce that the Navy has made a commitment to get 50% of its energy from renewable sources, like biofuels, solar and wind, by 2025. That's the most ambitious goal for renewable energy in the country—higher even than California's!
"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.'
"Mabus vigorously countered the argument that renewable energy is more expensive. 'Well of course it is! Every new technology is more expensive. What if we hadn't started using computers because they were more expensive than typewriters? What if we hadn't started using cell phones because they were more expensive than land lines? Where would we be?'
