Many solutions have been put forth to reduce the national dependency on oil. Some solutions suggested in the book Energy: Science, Policy and the Pursuit of Sustainability by Robert Bent, Lloyd Orr and Randall Baker are severe increases in oil taxes or removing oil subsidies efforts to increase the cost of gas and evoke a reduction in oil consumption.
Instead of implementing these drastic and expensive measures, perhaps by providing viable transportation alternatives, the reliance on oil will begin to decrease. One new area of technology that has the potential to facilitate this is the electric car.

Turning to electric cars instead of traditional cars can bring the fuel source to America and reduce our dependency on foreign sources of energy. The electricity generated and used by electric cars comes from power plants that utilize coal and natural gas. Though coal can be very detrimental to the environment, natural gas is a relatively clean source of energy that has been recently discovered to be in great supply throughout the United States. Hydraulic fracturing is a new technology that is allowing vast amounts of natural gas to be extracted from previously unproductive shale.
Though currently the electric car can only travel about 100 miles on a single charge, new battery technologies are being developed to increase this distance dramatically. Improving batteries would make electric cars a cost-effective and energy conscious alternative to traditional vehicles. Increasing the number of electric car charging stations throughout the country and advances in technology have the potential to awaken the public to the possibilities of reliable gas-free transportation. In the near future, electric cars could become a serious alternative to traditional cars and allow the nation to shift away from foreign oil and toward domestic sources of energy.
