Energy-saving boxes: Too good to be true? M by Brian Sloboda mailbag@ruralmissouri.coop ost of us think we’re too smart to fall for a scam. Yet every year, thousands of folks are separated from their hard-earned dollars by putting their faith and trust in another person’s sales pitch. There’s no shortage of hucksters pretending to help consumers save energy. These types of scams generally center on misstatements of science or confusion over an electric utility’s energy-efficiency programs. The most popular scam right now involves a device that promises to save energy without requiring you to make any changes in behavior, turn anything off or adjust the thermostat. People who sell these “little boxes” often claim outrageous energy savings — sometimes as much as 30 percent or more — couched around legitimate utility terms such as power conditioning, capacitors and power factor. The marketing spiel usually goes something like this: The model being sold will control alternating current power factor and reduce electric bills. It will condition your power and make appliances last longer. It uses no power and has no moving parts. It will make motors in your home run better. Accompanying materials often caution “your utility doesn’t want you to know about this device.” That last part is true — because these boxes are a rip-off. What’s the reality? While electric cooperatives use various components to correct power factor for commercial and industrial consumers, power factor correction is not a concern with homes. Engineers at the University of Texas-Austin concluded that one of the units could produce no more than a 0.06 percent reduction in electric use in an average house. What’s Power Factor? Power factor is the ratio between the electricity we use (real power) and the amount of electricity a utility provides (apparent power), expressed as a number between 0 and 1. The average home has a power factor of 0.9, or 90 percent. This means even if an electrical system isn’t performing at its best (1 or 100 percent), utilities deliver extra power to make sure consumers get what they pay for. When power factors come in below 1, special equipment like capacitors are used to keep an electrical system in balance. Real World Example: You buy a soda for $2. The soda jerk may pour a bit extra in the glass to make sure it’s full. You’re not charged for any soda that spills over the rim. Source: NRECA The Electric Power Research Institute, a Palo Alto, Calif.-based non-profit research consortium made up of electric utilities, including electric cooperatives, recently tested one of the most popular residential power factor correction products and found that it generated average power savings of just 0.23 percent — far from the 30 percent claimed by its manufacturer. At that rate, it would take typical homeowners more than 70 years to recoup their investment. In short, these devices are nothing more than ordinary capacitors employed in electronic circuits to store energy or differentiate between high- and low-frequency signals. Companies selling these products change names quickly and often. They move from town to town looking for new victims. There are several questions you should ask a sales representative when reading an ad for the next magical cure-all: • Does the product violate the laws of science? For example, does it claim to be capable of “changing the molecular structure . . . to release never-before tapped power.” If true, the invention would quickly be sold in every store across the country, not marketed through fliers or a poorly designed website. • Was the product tested by an independent group? If the product’s performance was not tested and certified by a lab or entity not connected to the company selling it, be very skeptical. • Is it too good to be true? If so, it probably is. A video getting play on the Internet shows a consumer reporter for a TV station testing one of these little boxes. By looking at electric bills before and after installation, he concludes the device is a good buy. However, an excessively hot or unusually cool day can cause one month’s electric bill to run significantly higher or lower than the previous month. Wise consumers always ask to see electric use for the same month from the previous year or years — not the previous month — and factor in weather anomalies for any savings claims.
