1. Replace your old holiday lights with light-emitting diode (LED) light strings.
  2. Plug your indoor and outdoor lighting displays into a timer set to run during the earlier evening hours. If you don’t use a timer, be sure to unplug your lights when you go to sleep or leave home.
  3. Cook as many dishes as possible in your microwave over the holidays. Because microwaves cook food so quickly, the typical model uses as much as 75% less energy than a conventional oven.
  4. Use your slow cooker. For about 17 cents worth of electricity, you can prepare an entire meal.
  5. When using your oven, check cooking progress by looking through the window. Opening the oven door for even a few seconds lowers the temperature inside by as much as 25 degrees. If your stove doesn’t have a window, try not to open the door to check your food until it’s as close to the expected finish time as possible.
  6. When cooking on your stovetop, match the size of the pan to the heating element. More heat will get to the pan and less will be lost.
  7. Turn down the thermostat when holiday guests arrive. Those extra bodies mean free heat.
  8. Taking a holiday trip? Turn off and unplug all equipment that pulls power, such as TVs, computers, phone chargers and game consoles, and lower your thermostat.
