Almost all items that you leave plugged in, whether on or off, use a small amount of energy that contributes to your monthly electricity bill. We might unplug some appliances inside our home to help lower these costs, but items in the garage are often forgotten about. Not only can these items cause an increase in energy consumption, but they also can pose a potential fire hazard. If you or someone in your household regularly uses tools or equipment in the garage, the risk (and energy drain) is even higher.
Ahead, we walk you through the commonly overlooked items that should be unplugged when not in use—and why it matters. With a little effort and consistency, you can cut unnecessary costs and help keep your home safer.
With so many modern tools and devices now powered by rechargeable batteries, it’s common to leave chargers plugged in around the clock for convenience. However, doing so isn’t the best idea—both for your energy bill and your safety. Leaving battery chargers plugged in when they’re not in use or after a battery is fully charged can lead to overheating, shorten the battery’s lifespan, and waste electricity. To avoid these risks, it’s best to unplug chargers whenever possible.
If you keep an air compressor in your garage, make it a habit to unplug it when not in use. This simple step helps conserve energy, reduces the risk of fire, and extends the life of the machine. For added safety, always release any remaining air from the tank after switching off and unplugging the compressor. Doing so prevents condensation buildup inside the tank, which can eventually lead to rust. Keeping the unit unplugged also protects it from potential damage caused by power surges.
Garages often rely on a mix of power strips and extension cords to supply electricity to tools, lights, fans, and other project essentials. While convenient, leaving them plugged in at all times can pose a fire risk. Overloading them with too many items can lead to overheating, which might damage connected devices, or worse, start a fire. Unplugging power strips and extension cords when they’re not in use not only enhances safety but can also help you save a bit on your electricity bill, as they continue to draw power even when idle.
Similar to the other items on this list, the benefits of unplugging portable work lights (such as clamp lights, hand lamps, and floodlights) are mainly lowering energy consumption and preventing dangerous fires. While simply switching them off might seem sufficient, it’s safer to fully unplug them when not in use. This helps prevent unnecessary energy waste and lowers the risk of electrical fires.
Space heaters are popular for those who live in cold climates but still want to work comfortably on projects in their garage. However, they can pose a serious fire risk if they overheat or are left unattended. To stay safe, always turn off and unplug your space heater when it’s not in use—even if you’re just stepping out for a bit.
