Colder temperatures often mean higher energy costs. According to the Department of Energy, space and water heating together eat up as much as 63% of the average American’s annual energy consumption. But the DOE also estimates as much as 20% of the energy we pay for to create and maintain warmth in our homes is wasted due to drafts and other inefficiencies. Here are a few simple steps to help you reduce energy waste and save money this winter.

Seal Up Drafts

Insulation helps keep cold air out, and warm air in. But just one gap could allow your precious heat to slip outside. Conduct a simple energy audit by walking around your home and identifying any spaces where you feel cold, drafty air. Then check for the source — usually window frames, door frames, or outlets and light switches on external walls — and consider caulking, sealing, or insulating it.

Turn Down Your Water Heater

Water heating consumes as much as 18% of an average American household’s energy costs. Lower those costs by lowering the temperature your water heater is set to maintain. Most manufacturers set water heaters to 140 F, but the DOE recommends setting it to 120 F. Here’s how to adjust it.

Adjust Your Thermostat

Investing in a programmable thermostat is a fantastic way to save on energy costs. Lowering the temperature when you’re not at home, and only setting it to around 68-70 F when you are, can save you as much as 10% on heating costs, the DOE estimates. Bonus: Setting a schedule to lower temperatures at night can actually help you get a better night’s sleep.

Use Your Ceiling Fans

Yes, these summer favorites can actually help you feel warmer in winter months. Most ceiling fans have a switch to flip the direction they rotate and how they circulate air. Adjusting it to slowly rotate clockwise can force warmer air to move further down in the room.

Get Cozy

The simplest, easiest step you can take? Dress warmly. Trade out your tank tops and T-shirts for sweaters, sweatpants, and chunky blankets!
