- Part 2 of a 3 Part Series on Energy Conservation -
Another set of problems that have simple solutions are phantom loads and miscellaneous electric loads (MELs). What are they and how do they apply to this issue? Well, a phantom load is energy loss from an appliance or gadget in standby mode or not in use. Just being plugged into the power circuit can cause energy losses. Major appliances such as refrigerators, washing machines, and ranges are prime contributors to phantom load losses.
MELs on the other hand are essentially the sum of the vast collection of small electronic devices we use on a daily basis such as power adapters, computers, printers, televisions, phones, garage door openers, etc. Although each device may only draw a small amount of power (in both operation and standby mode), the sum of these devices can and will add up to a significant amount of energy consumption. It is estimated that in the United States MELs equal approximately 6 percent of residential energy use.
So, how do we solve this problem? Once again, educate our people on this issue so they will have the power to make adjustments. Most people don’t even know that this problem exists and, when given the knowledge, many will act upon the information and modify their habits.
Small changes such as unplugging electronic items that are not in use can assist in solving the problem. Plug televisions, media components, computers, printers, monitors, and other electronic devices into surge protector/power strips and turn the strips off at night. You would be amazed at how much power computers, cable boxes, and digital television recorders consume just in one night, even in standby mode or turned off. Another great way to identify the worst phantom power offenders is to purchase an inexpensive watt meter that will show you the electrical draw in standby mode. This alone will help you target those least efficient items first and capture the savings as low hanging fruit. Did I mention that these solutions are low to no cost improvements?
