Georgia Tech life-cycle study finds TCO of medium-duty electric and diesel delivery trucks similar; electric life-cycle energy use and GHG lower than diesel

Green Car Congress

Brown (2013) Electric Urban Delivery Trucks: Energy Use, Greenhouse Gas Emissions, and Cost-Effectiveness. The relative TCO is most sensitive to the diesel truck’s fuel consumption (or fuel economy), VKT, and diesel fuel price scenario. The NPV of TCO differential is sensitive to battery replacement, battery price, and EVSE price.
