In recent years, practical hybrid cars have hit the road—cars in which the gasoline engine runs a generator that charges batteries that run an electric motor. These cars offer increased efficiency, but significantly greater efficiency could be provided by a purely electric car run by batteries that you charge by plugging into an electric outlet in your house.But there’s a practical problem with such vehicles: the time necessary to recharge the batteries. If you refuel your car with gas at the pump, you add 130 MJ of energy per gallon. If you add 20 gallons, you add a total of 2.6 GJ in about 5 minutes. That’s a lot of energy in a short time; the electric system of your house simply can’t provide power at this rate.There’s another snag as well. Suppose there were electric filling stations that could provide very high currents to recharge your electric car. Conventional batteries can’t recharge very quickly; it would still take longer for a recharge than to refill with gas.One possible…
it the minimum average power? 13. An energy-efficient fluorescent lightbulb operating at power Pı = 28 W can produce the same level of brightness as a conventional incandescent lightbulb operating at power P, 100 W. Lifetime of the energy-efficient bulb is T = 10000 h, and its purchase price is B1 = $4.50. Lifetime of the conventional bulb is T2 = 750 h, and its purchase price is B2 = $0.42. Suppose electrical energy costs R = $0.20/kWh, i.e. 20 cents per kilowatt- hour. a) Calculate the total cost of using energy-efficient bulbs over 10,000 hours. b) Calculate the total cost of using conventional bulbs over 10,000 hours. Note that you must include both the cost of purchasing the bulbs and the cost of energy.

Problem 6: Suppose the cost of an incandescent bulb is 23 cents and that electricity costs 12 cents/kWh. Compact fluorescent lightbulbs (CFL), while they are more expensive, use 1/10 of the power for the same amount of illumination.

Assume both lightbulbs run for 1000 h.
