In many homes today nearly every light bulb is now a LED, or light-emitting diode light bulb. Even though these are much more efficient than incandescent or CFL bulbs, making sure they're off when you're not using them is still a good way to conserve energy.
While the LED replacement for a regular 100 watt incandescent bulb might only use five watts, if you leave it on, you'll still be wasting electricity.
Actually there are a number of things you can do to make your home more efficient that do not cost a dime:
- Turn off lights when you leave a room. This is one of the most overlooked efficiency opportunities in our daily lives. It is also one that I seem to constantly be reminding my kids to do.
- While ceiling fans can help cut summer energy use, they can also be substantial energy users-depending on how they are used and what kind of lights, if any, are part of the fan package. About 80 percent of the possible savings from a more efficient ceiling fan happen in the lighting. So be sure any new fans you buy contain ENERGY STAR® labeled lighting. Set ceiling fans to rotate clockwise in cold months and counterclockwise in warmer months.
