4. Utilise Smart Power Strips and Standby Mode Management
Many modern appliances continue to draw power even when turned off, creating what is known as a "phantom load" or "vampire power." This standby consumption can account for 5-10% of a household's total electricity use. Smart power strips provide an automated solution, cutting power to devices in standby mode and eliminating this unnecessary energy drain.
How It Works
Smart power strips are designed to detect when a primary, or "master," device is turned off or goes into standby. Once this happens, the strip automatically cuts power to the "switched" outlets where peripheral devices are connected. This is perfect for home entertainment centres or computer setups, where turning off the TV or PC also powers down speakers, gaming consoles, and printers.
For instance, a TrickleStar smart power strip can save a home office setup over $100 annually by simply managing these peripheral loads. Similarly, individual smart plugs can be scheduled to turn off at certain times, giving you precise control over your energy usage.
