The Obama administration envisions a “low-carbon, low-petroleum” future where Americans tele-work, tele-shop, walk, bike and use carpools or mass transit if they must leave the neighborhood at all.
A study released Friday says the U.S. has the potential to reduce petroleum use and pollution in the transportation sector by more than 80 percent by 2050. In other words, gasoline-powered cars may go the way of the dinosaur, and many Americans may end up living in planned, mixed-use, “walkable” neighborhoods, built along mass transit lines.
The study — titled Transportation Energy Futures  — offers “an inclusive approach,” including increased fuel economy for all types of vehicles; reduced use of transportation by car; and the expanded use of low-carbon fuels, such as biofuels, electricity, and hydrogen.
Under a section called “Transportation Demand ,” the report sees opportunities to save energy “through community development and built environment strategies.”
