Greening New York's Subways
Public transportation saves energy. Instead of individually consuming hundreds of gallons of gasoline, if not thousands, the great mass of workers in Boston, Chicago or New York commute powered by electricity or efficient diesel engines. Saving fuel and other environmental economies are thus embedded in the very way the municipal authorities charged with mass transit do business. So it comes as no surprise that New York's Metropolitan Transportation Authority (MTA) has an ambitious plan to "green" its operations.
