Switch out your old holiday lights for LED lights.
LED lights use up to 90% less energy than traditional bulbs and can last up to 40 holiday seasons. At 12 hrs. a day for 40 days, a string if incandescent lights add $10 to your energy bill, while a string of LED lights adds just over $0.25.
Put your lights on a timer.
Set timers for your holiday lights to turn off before bedtime so you don't accidentally leave the lights on all night.
The average U.S household spends $100 per year powering devices that are not in use. Take a few minutes to turn off electronic devices and unplug anything that's not currently in use. Using a power strip is an easy way to power down all of your lights/devices at once.
Stop peeking at cooking food.
Use the oven window to check on baking foods. Opening the oven door even for a few seconds can result in as much as a 25 degree heat loss.
Cook as much as you can in the Microwave.
Because microwaves cook food so fast, the typical model uses 75% less energy than a conventional oven.
Drive your way to fuel savings.
Whether you are driving across town to do errands or across the country to visit family, fuel costs can add up over the holidays. One way to reduce fuel consumption is to empty your car after all of your driving trips. An extra 100 pounds in your vehicle could increase gas costs up to $0.08 a gallon.
Install a programmable thermostat.
Don't pay for warm air that you are not using. By installing a programmable thermostat you can save money on your energy bills. Lowering your thermostat 10-15 degrees for 8 hours can save 5-15% a year. For every 1 degree you lower your thermostat you may reduce your energy use by 1-3%
