Ecotopia: Which Is The Most Eco-Friendly U.S. City?

"In the real, energy-dystopic Northwest, a typical resident burns more than three times as much gasoline per day as a typical New Yorker...The difference in driving rates is easy to explain: metropolitan New York is compact and well served by public transit; the Northwest sprawls. Studies of 68 cities on four continents show that as the population density of a neighborhoods rises, driving drops off, transit use surges, and walking and cycling flourish. More than any other factor, density is the key to reducing our dependence on motor vehicles. And New York is the New World's density capital, which makes it the winningest city not only for baseball but also for transit and walking."
