Smart home devices can play a major role in helping you create a more energy-efficient home. For example, smart LED light bulbs use at least 75 percent less energy and last 25 times longer than incandescent bulbs. They can also be dimmed or turned off remotely to save even more energy. Smart thermostats can save you between 10-20 percent on heating and cooling costs, a major source of home energy use. You can also identify potential issues with your HVAC, sparing you significant costs down the road. In addition, smart plugs/power strips can reduce standby power (when appliances use energy even when turned off). Standby power can account for up to 10 percent of your home’s total energy use.
