A Statement of Task The NRC will appoint an ad hoc study committee to production of the vehicles or supplying the energy conduct a comprehensive analysis of energy use within the requirements for the vehicles. Costs would be put on light-duty vehicle transportation sector, and use the analyses a consistent basis to serve as a better index of com- to conduct an integrated study of the technology and fuel paring options. Scenarios will consider technology options (including electricity) that could reduce petroleum as well as policy options and consider the likelihood consumption and greenhouse gas emissions.
