 Each Tesla uses between 0.24 and 0.30 kilowatts per hour per mile or about 4,500 kilowatts per hour per mile over a year at 15,000 miles of driving. What does this mean? It means the average American household without an in-home EV charging station consumes 30 kilowatts a day or 10,000 kilowatts over a year's lifetime.
