NYC tests hybrid garbage trucks
The New York City Department of Sanitation is testing out four models of hybrid diesel-electric garbage trucks as it considers how to upgrade its fleet. The trucks have been designed to look and operate like typical, all-diesel powered trucks but use 30% less fuel and produce 30% less emissions. They accomplish these reductions by generating energy in an electric motor when the trucks slow down and storing it in a battery to be used in tandem with the diesel engine. Garbage trucks are ideal for this technology because they make frequent stops, regenerating energy several times on each block. The city plans to assess the four models over the next year before beginning to purchase up to 300 new vehicles per year.
