| 摘要： | The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy has defined milestones for its Vehicle Technologies Office (VTO) technology programs. This report provides estimates of the benefits that would accrue from achieving these milestones relative to a base case that represents a future in which there is no VTO-supported vehicle technology development. This was done by estimating fuel use, primary energy use and greenhouse gas (GHG) emissions from light-, medium- and heavy-duty vehicles, including energy and GHG emissions from fuel production for the base case and the program target case. The target case represented the future with completely successful deployment of VTO technologies. Market penetrations of different vehicle types with and without VTO technologies were projected using market share models, and a stock and energy accounting model was used to make projections of energy consumption and GHG emissions for the base and target cases. The differences between the base case and the target case were attributed to VTO technologies. Improvements in fuel economy of various vehicle types were attributed to individual VTO technology areas, which included batteries and electric drives, advanced combustion engines, fuels and lubricants, materials (i.e., reducing vehicle mass, also called lightweighting), and for medium- and heavy-duty vehicles, reduction in rolling and aerodynamic resistance. |
