Collectively these tiny changes can add up to huge savings. Try a few or all to reap the benefits of a fatter bank account in 2016—and beyond.
Get an energy audit
Consider this a checkup for your home: Many local utility companies offer energy audits (often for free), where experts assess your home’s energy consumption patterns looking for improvement areas where you could cut back on guzzling electricity, gas, or water (and also lower your utility bills). Auditors may do this remotely by poring through your records, or they visit your home to examine everything from its windows to duct work to shower heads—saving you as much as 30% of your monthly bills.
Adjust your water heater
Most people set their water heaters on high. The amount of energy needed to keep gallons of water at scalding for no reason? A lot. Lowering it by just 10 degrees Fahrenheit will save you from 3% to 5% on your heating costs. Also, buy your heater a nice blanket to keep heat in and tack on an additional 4% to 9% in savings.
Swap your lightbulbs
Switching to low-energy lightbulbs is a quick and easy way to reduce lighting costs. A 60-watt bulb retailing for $6 will save between $30 and $80 over its lifetime. The average household has 50 bulbs—so that’s a minimum $1,500 in savings! But there’s no need to go out and buy $300 worth of lightbulbs all at once. Swap out the bulbs you use every day—kitchen and bedroom—and leave the barely used ones in basements or attics until they burn out.
Kill your home’s energy vampires
Those little lights all over your house that indicate printers and chargers are on but not in use? They’re “energy vampires” sucking dollars out of your wallet, an average of $165 a year for a typical U.S. household. The low-tech solution? Unplug these items before bed, which will save you as much as 10% on your energy bill. The high-tech solution? Power cords such as the Embertec Emberstrip AV+ ($79.95) that will turn off equipment when it senses they’re not in use.
Wash your clothes this way
Switch to cold water washes. Yes, your clothes will still get clean—some stains come out more readily in cold water—and you’ll save about $60 a year. As dryers account for 12% of energy in an average household, consider line-drying clothes in nice weather to save you almost $200 per year. Or, if you do use a dryer, clean your vent, which will reduce energy costs by $9 to $12 per month, says Doug Rogers, president of Mr. Appliance.
Strip your windows in the winter
In the winter “even the smallest gaps around a window or door frame allow air to leak inside,” says Mark Liston, president of Glass Doctor. “An eighth of an inch gap under a 36-inch wide door will let in as much cold air as a 2.4-inch diameter hole punched in a wall!” That means in the winter, sealing cracks around windows and frames is a no-brainer that can bring down the heating bill between 10% and 15%.
Film your windows in the summer
And as for the summer, when the sun beats through your windows and bakes your home? For that, you can add window films—an imperceptible layer that acts like sunglasses, filtering out infrared and UV rays. A whole roll of it will run you around$25 but can translate to an average of 20% to 25% reduction in energy costs via the AC. Added benefit: It keeps colors in paintings and carpets from fading, says Mike Byrd, program manager for Madico, which provides window films for the Smithsonian, the Louvre, and many other architectural landmarks.
Cut the cord
Getting rid of cable and your landline will save you about $100 a month. Keep your fast Internet and consider buying a $35 Chromecast—a device that slings streaming shows from your cellphone to your TV.
