Researchers at MIT studied the driving patterns and battery capacity of electric vehicles— using a 2013 Nissan leaf as the base for their calculations. They determined that “range anxiety”—The fear that a car’s battery will die without timely access to a charging station—is overly exaggerated.
If battery technology improves as expected, electric vehicles could replace 98 percent of existing vehicles by 2020. As of current standards; having to relying on a single charge, today’s electric vehicles could replace 87 percent of daily car travel in the U.S. and cut gasoline consumption by 60 percent.
Currently electric vehicle sales in the United States are only about 1% of the total car sales. However that is expected to climb quickly as manufactures and the public become more comfortable with the idea of an all electric future.
