NRC report concludes US LDVs could cut oil consumption and GHGs by 80% by 2050; reliance on plug-ins, biofuels and hydrogen; strong policies mandatory

Green Car Congress

The unit cost of batteries will decline with increased production and development; in addition, the energy storage (in kilowatt-hours) required for a given vehicle range will decline with vehicle load reduction and improved electrical component efficiency. Hybrid LDVs might reach 94 mpg (2.5 l/100 km) by 2050.
