Does electrical car save money regardless of pollution and the "Inconvenient Truth"? I always conceived that driving an electrical car would save lots of money without a second thought. However, with the following figures, I am not sure now. For a small-middle sized regular car with a 140 horse-power engine and 35 miles/gallon mileage, it would cost about $7 for one hour driving at the speed of 70 mile/hour and gas price of $3.50/gallon. Then, a similarly powered electrical car with 100 KwH motor would cost about $15 for each hour driving, assuming electricity price about $0.15/KwH - double the cost of driving the petroleum engine car. Even if we could reduce the electrical motor to half of the horsepowers thanks to lighter weight and more efficient mechanics, it still doesn't save money. Does that mean the oil price has to go up to $200 barrel to make people serious about alternative energies? What’s wrong with the numbers?
