the single most effective thing we could do
the single most effective thing we, as a nation, could do to reduce fuel usage.... short of getting rid of big SUV's
switch to diesel engines.. like in europe.. diesel engines are 40% more efficient than a gas engine and the new models meet or exceed emissions..
Small diesel powered cars could easily make our usage of oil be cut in half.. combine that with the biofuel production wed be sitting in a much better situation. biodiesel is half the emissions of regular diesel
And even imagine a diesel electric hybrid ... 100mpg would be a easily attainable tank average
