Question

In doing an energy audit of a home you find that both the front and the back porches of the home have overhead light fixtures set on timers. Each porch's light fixture contains two 40 W incandescent bulbs, and the timers turn the porch lights on for 8 hours every day. If the homeowner replaced the 40 W bulbs with equivalent 4.5 W LED bulbs, how much would the annual energy consumption be reduced in kWh?​
