Many homeowners are familiar with the advice to unplug appliances when they’re not in use, but few realize just how much this habit can affect both household safety and energy expenses. A surprising number of devices continue to consume electricity even after being turned off—a hidden drain often called “phantom power.” Over time, this standby usage can add anywhere from $100 to $200 a year to a home’s electric bill.

Beyond the cost, leaving certain appliances plugged in can increase the risk of fire. Space heaters are especially important to disconnect, as they are a major cause of winter house fires and can become dangerous if they overheat or are placed near flammable objects. Hair tools like curling irons and flat irons also pose a hazard, since they reach extremely high temperatures and can ignite nearby items if accidentally left plugged in.

Kitchen appliances deserve attention as well. Toasters and toaster ovens can collect crumbs that may smolder, and older units can sometimes switch on unexpectedly. While modern clothes dryers shut off automatically, their electrical systems still draw power and are safer when unplugged.

Many everyday electronics quietly use electricity around the clock. Phone chargers, televisions, gaming consoles, and coffee makers all contribute to unnecessary energy use when left connected. Using smart power strips or unplugging devices after use can significantly reduce this constant drain.

By forming simple habits—like unplugging appliances right after using them—homeowners can lower energy waste and improve household safety. These small actions take little effort but offer lasting benefits for both your wallet and your home.
