New York, NY - More Yellow Cabs Turning Green

New York, NY - They may be yellow cabs, but they're also green.

The number of environmentally friendly taxicabs on New York City streets could grow tenfold after this summer, when the city designates a significant portion of new taxi medallion licenses for alternative-fuel cabs.
The Taxi and Limousine Commission is scheduled to sell 308 medallions in June, and Mayor Michael Bloomberg has directed the agency to assign 254 for vehicles that use hybrid fuel technology or compressed natural gas, which boast better mileage and lower emissions.

Now, just 27 alternative-fuel cabs are in operation.
