Consumer demand for plug-in electric vehicles is quite uncertain.

When the U.S. government established the goal of putting one million PEVs on the road by 2015, both the future of the technology and the financial capability of the U.S. auto industry were uncertain. Automakers could ramp up PEV production if consumer demand proves to be larger than expected. However, consumer demand for PEVs is quite uncertain and, barring another global spike in oil prices, may be limited to a minor percentage of new vehicle purchasers (e.g., early technology adopters and relatively affluent urban consumers interested in a “green” commuter car).
