- Should You Buy an Electric Car? Do the math. This article says that the EPA rating for the Nissan LEAF is exactly 30 kWh per 100 miles Assume you drive 15,000 miles per year Assume you pay 7.8 cents per kWh (kilowatt-hour) Assume your current vehicle gets 32 miles per gallon and gas cost $2.50 per gallon Which is cheaper to drive, your current vehicle or the Leaf?* What else should you consider before purchasing an electric vehicle? Ready to decide? Make an argument for either keeping your current vehicle or for getting an electric vehicle. Don't have a car? Make an argument for using public transportation and ride-sharing services.There are approximately 260 million passenger vehicles registered inthe United States.
