Do tractor trailers, boats, airplanes and locomotives currently run on fuels we get from Venezuela and the Middle East?
Can we get better mileage from any of those?
For the most part, all are also fueled from petroleum. The exception would be those trains that are electricly powered, primarily commuter lines.
There is major opportunity in this area by constructing more electricly-powered, high-speed mass-transportation systems in our nation's most densely populated regions and urban areas. The electricity could be generated utilizing clean-coal and nuclear technology, thus reducing our dependence on imported petroleum.
