 A new type of hybrid work truck is being tested in Pearl Harbor. These trucks are powered by both diesel and electricity, which reduce both emissions and fuel costs for the base. During these tests, data is being recorded to find how efficient the trucks are at saving fuel. Through the study, it's shown that there's an approximately 20 percent fuel efficiency over our conventional truck, which runs off of the diesel power. They're still crunching the exact numbers, but there is a significant improvement in fuel economy. NAVFAC-Hawaii has started using these trucks during this testing phase in the hopes to replace their current diesel counterparts. Hybrid trucks like these have proven to be just as good, if not better, than trucks powered solely by diesel. To learn more on renewable energy, visit greenfleet.dodlive.nl
