The EDTA says promoting plug-in vehicle sales is a matter of national security and cites foreign-oil purchasing statistics as proof. Specifically, the US increased oil imports by about seven percent last year, to $451 billion. By pushing harder for plug-in vehicle adoption – by way of helping to fund technology improvements and electric vehicle charging installations – the government may be able to stem that growth and even cut oil import numbers as fleetwide fuel economy rises and gasoline purchases drop. Currently, the plans from various automakers say that about two-dozen plug-in models will be introduced during the next three years. The number of plug-in charging stations in the US should surge to about 1.5 million in 2017, way up from about 5,000 now.
