Thanks in part to ARRA funds, the NYC Dept. of Sanitation purchased five brand-new hybrid electric street sweepers. Delivered in fall 2011, these five hybrids will join the city’s total fleet of 450 sweepers, helping to keep the streets clean on a daily basis and after special events like the Thanksgiving Day parade or New Year’s Eve celebration in Times Square. The City is the first in the nation to pilot this hybrid technology.
A standard street sweeper consumes 7,500 gallons of diesel fuel per year. The hybrid model cuts diesel fuel usage by roughly one-third. So combined, these five hybrids will reduce fuel consumption by 11,250 gallons per year, which translates to $33,750 annual savings. The City will also lower carbon dioxide emissions by 100 metric tons per year, equivalent to removing approximately 20 passenger vehicles from the road. Lessons from the pilot will help inform future street sweeper purchases and serve as a model for other jurisdictions around the country. If the pilot is successful, there is potential to multiply the impact by 90 fold in New York City alone.
