The Autocar E3 uses stored hydraulic energy to power the truck as it moves from house to house for waste collection duty. The company claims that the hybrid system allows for a fuel savings of nearly 50 percent versus its diesel-only counterpart. Wow. In addition, CO2 emissions are decreased by 38 tons per year. Greening up the act of collecting garbage is one benefit of the hydraulic hybrid refuse truck, but we'd bet that most municipalities choose hybrids to save money on fuel, which can amount to more than $18,000 over the vehicle's 10-year useful life.
