To improve real national security, we must improve our energy security. My amendment to the Defense authorization bill, which was defeated in committee yesterday, would have taken two steps in that direction by boosting funds for advanced power technologies and for alternative fuel infrastructure at military bases. As the single largest buyer of fuel in the U.S., the Defense Department has an opportunity, even an obligation to lead the way in diversifying our energy portfolio. And no time could be better than the present. America's addiction to oil from any source means that our security is vulnerable and will continue to be until we have the vision to look beyond the gas pump.
