When to turn off the lights?
The question of when to turn off the lights to save energy might seem like common sense, but in fact, the answer depends on what kind of lights you have. Making smart choices about this, and some other basic household practices, can help you save money on your electric bill.
The U.S. Department of Energy’s website at www.energy.gov offers the following tips:
Traditional incandescent lights should be turned off whenever they are not needed, because they are the least efficient type of lighting; 90% of the energy they use is given off as heat, and only about 10% results in light. Turning lights off will also keep a room cooler, an extra benefit in the summer.
The newer compact fluorescent lights, or CFLs, use less energy when they are on. Additionally, switching a CFL on and off shortens its life. So, if you will be out of a room for 15 minutes or less, leave it on. Switching to Energy Star qualified CFLs throughout your house will cut energy consumption for lighting by about 25%.Beware the vampires
Often, appliances and electronic equipment continue to draw a small amount of power even when they are switched off. Computers, DVD players, TVs, stereos, coffee makers and other kitchen appliances drain electricity, sometimes dubbed "vampire" loads, when they are not in use.
