As a result of the age of abundance, many people are still in the habit of leaving lights on even when they are not in the room. It takes very little effort to flip a switch, and it saves energy that is being entirely wasted. Once you get into the habit of turning the lights off, you won't even notice that you are doing it; it becomes automatic. If everyone in the world begins to do this, the energy savings will be enormous.
Compact fluorescent bulbs are far more efficient than incandescent bulbs. A 15 watt compact fluorescent produces the same amount of light as a 75 watt incandescent, saving 80 per cent of the power for the same result. A combination of using compact fluorescents and turning them off when you don't need them can radically reduce your electricity use for lighting.
In places where you need lights and can't turn them off, but don't necessarily need the room lit up to maximum brightness, installing dimmer switches will reduce electricity use. A dimmer switch allows you to adjust the level of light coming from the bulb to a comfortable and adequate level.
Coal for Electricity
Even though the lights burning in your house look as clean as can be, there's a good chance that they are being powered by a polluting coal plant. Despite the fact that many people think that coal is the energy of the past, it is still being used in vast quantities. Fifty-seven per cent of the electricity in the United States is still produced by coal.
If you like to read in the evening, get in the habit of sitting closer to your partner and using the same bulb. This is an easy way to eliminate what can be a large amount of electricity use over a period of years. And it might improve your marriage!
Using Fewer Bulbs
If you have a ceiling fixture that is brighter than it needs to be, take the cover off and see how many bulbs are in it. Some fixtures have three, four, or even five bulbs in them. Unscrew bulbs until you have an adequate, but not excessive, level of illumination in the room. If you can get by with two bulbs in the fixture instead of four, you've just cut the expense and energy usage of that fixture in half.
