There's Oil on Main Street

A 2001 study showed that we can save more oil by building more fuel-efficient cars than by expanding drilling under U.S. soil or in our oceans. Deron Lovaas sees black gold in our cities and suburbs.

Lovaas writes that "An aggressive expansion of transit in cities and suburbs, for example, could save us almost 4 million gallons of oil each day by 2030."

Lovaas takes a closer look at a new, more energy-efficient light rail currently being tested by Dallas Rapid Transit (DART):

"This prototype can run on overhead electrical lines as well go five miles on a rechargeable battery. It also uses regenerative braking technology, which conserves power by channeling braking energy back to the battery."
