Do Energy Saving Devices Really Work?

Energy savings devices are touted as one of the best ways to help you save energy in your home. They track and adjust the amount of energy that is being used by an electric appliance. They are marketed under many different names….but do they really work?

Energy saving products can be found in most hardware stores. You use them by plugging them into an outlet, and then plugging the cord for your television, fan, computer, etc., into the device. The device will monitor the amount of power being used by your item and then lower it to an amount that will keep the device running but will also lower your usage. They are simple to install and many people swear by them.

However, according to electronics professionals these devices may not be all that they are cracked up to be. There are two separate types of energy saving devices. The first takes advantage of the natural lag that happens when an electronic item is plugged into a power outlet. The device corrects the lag and the reading on the device indicates that you use less power. In theory, you are using less power but you are actually using the same amount. The device will read that the amount of amps being used have been lowered, but the device does not account for the power factor involved in energy readings. The amount of watts that you use equals the volts times the amps times a power factor. Since the power factor is not accounted for the device isn’t actually giving you’re the accurate reading. The compensation that the device uses increases the power fact. The number of watts that are being used is virtually the same, which means you aren’t saving any energy.

The second type of device reduces the amount of the effective voltage by turning the incoming power off and on very quickly. It reduces the amount of volts being supplied through the outlet, which means that fewer volts are being used. This form of energy saving device shows less amps on the readout, but it actually can wreak havoc on the item you are plugging into the outlet. The item has to run longer in order to get the job done. There may be some energy savings from items that have a lighter draw on the power, but in general the savings are negligible.

Without an understanding of electricity, most consumers are tricked into believing that electricity saving devices are actually helping them lower their electric bill. If energy saving devices don’t work, then what are your options? There are no short cuts when it comes to saving energy. You need to monitor your electricity use and unplug items when you aren’t using them. Make sure to set your thermostat at a reasonable level and make sure your insulation around windows and doors is working properly. These tips will do you more good than wasting money on an energy saving device.

    I have installed energy saving light bulbs for all my home lightnings and I do save on my electric bill. Further more I found that there were less heat generated from these bulbs. I looking forward to use the led type light bulbs when the prices are more affordable.
