It’s Never Been Easier to Save Energy at Home

There are hundreds of ways you can save energy at home every day.

It may not seem like swapping in an LED bulb or fixing a leaky faucet will do much to reduce your energy use or protect the environment, but if every household did just a few of the tips below, we would reduce energy consumption significantly.

Check out I&M’s video resources, tips and helpful facts for easy ways to cut your energy costs, and then choose a few to try.

Summer Energy Saving Tips

Tip #1

Install awnings on windows that get excessive sun in the late afternoon.

Tip #2

Increase your attic insulation if joists are showing.

Tip #3

Install a programmable or WiFi-enabled thermostat to set temperatures warmer when you are away from the house. You can reset to the cooler temperature before you arrive home.

Tip #4

Safely repair and/or apply weather-stripping to air leaks in the home – about 10 to 25% of energy used to cool homes escapes via air leaks. Areas to check include dropped ceilings, recessed lighting, attic entrances, ducts, door frames, window frames, electrical outlets and switches and plumbing/utility access.

Tip #5

Install a cover above your attic hole or hatch.

Tip #6

Use light-colored shades and window coverings.

Tip #7

“Smart” power strips can help reduce “phantom” energy use.

Tip #8

Aerators that easily screw into bathroom and kitchen faucets reduce water use – reducing water heater use. Efficient showerheads can also reduce water use.

Tip #9

Inexpensive plastic deflectors can direct air under tables and chairs.

Tip #10

Take shorter showers – they require less hot water.

Tip #11

Lower your hot water heater’s temperature to 120 degrees. Some are originally set at 140.

Tip #12

Use cold water when washing clothes.

Tip #13

Set your clothes dryer on a cooler setting; hang clothes dry when practical.

Tip #14

Make sure your ceiling fan is set to run counterclockwise in the summer, pushing cooler air down.

Tip #15

If using an air conditioner, close outside doors and windows.

Tip #16

Set your air conditioner thermostat to as high a temperature as you can be comfortable.

Tip #17

Turn off and unplug appliances when not in use. Many appliances use energy on standby power even if “off” – and eliminating this “phantom” energy can reduce household energy use by as much as 10%. Examples include devices with remote control (TVs, DVDs); devices with a “black box” power supply (printers, cable modems); chargers (cell phone, tablet, laptop); or appliances with a continuous display (clocks and devices with digital clocks).

Tip #18

Close curtains and shades on south-facing windows to block sunlight and heat during the day.

Tip #19

Avoid using heat-producing appliances such as ovens or dryers during the hottest parts of the day.

Tip #20

Move furnishings away from floor or return air vents.

Tip #21

Clear high grass and other vegetation close to your outside a/c unit.

Tip #22

Keep refrigerator door closed as much as possible.

Tip #23

Turn off lights in empty rooms and when they are not needed.

Heating Your Home

Tip #24

In the winter, keep curtains and blinds closed at night to keep cold air out, but open them during the day to let the sun warm the room.

Tip #25

If you’ll be going on vacation, lower the thermostat to 55°F. This will save energy while preventing water pipes from freezing.

Tip #26

If you have hardwood or tile floors, add area rugs to keep your feet warm.

Tip #27

Avoid using space heaters, including electric, kerosene or propane models. Not only are they expensive to operate, they’re also very dangerous.

Tip #28

If your home has electric baseboard heating, be sure to keep furniture and draperies away from the heaters, and leave at least a three-inch clearance under the heating unit.

Tip #29

If your home has a boiler system, avoid covering radiators with screens or blocking them with furniture. It’s also a good idea to add a reflecting panel behind radiators – you can purchase one at a home center or make one yourself with a plywood panel and aluminum foil.

Tip #30

Vacuum registers and vents regularly, and don’t let furniture and draperies block the air flow. Inexpensive plastic deflectors can direct air under tables and chairs.

Tip #31

Don’t set the thermostat higher than you actually want it. It won’t heat your home any faster, and it will keep your furnace running longer than necessary.

Tip #32

Install a programmable or Wi-Fi smart thermostat. If you use it to lower the temperature by 10 degrees for eight hours every night, you could reduce your heating bills by 10%.

Tip #33

If you have a forced-air furnace, do NOT completely close heat registers in unused rooms. Leave louvers slightly open to allow minimal airflow. Your furnace is designed to heat a specific square footage of space and can’t sense when a register is closed – it will continue working at the same pace. In addition, the cold air from unheated rooms can escape into the rest of the house, reducing the effectiveness of all your insulating and weatherizing.

Tip #34

Set your thermostat to “auto” so that the blower fan will not operate continuously. A 1/2 HP blower fan consumes 3850 kWh annually if run around the clock, and may only need to run a third or less if set on “auto.”

Tip #35

If you set your thermostat a little lower during winter months, you’ll reduce your heating costs 2-3% for each degree of adjustment. Changing the temperature from 72°F to 68°F could lower your energy bill by up to 10%.

Tip #36

Have your heating system inspected regularly. A $50-$100 annual tune-up can help reduce your heating costs by up to 5% and keep your system running at peak efficiency.

Tip #37

Change or clean your furnace filter once a month. Dust and dirt can quickly clog vital parts, making your furnace run harder and eventually break down.

Fireplaces

Tip #38

If you have a wood-burning fireplace, have the chimney cleaned and inspected regularly, and burn only fully dried hardwoods to produce the most heat output.

Tip #39

Check the seal on the damper by closing it off and holding a piece of tissue paper inside the firebox. If drafts blow the tissue around, repair or replace the damper.

Tip #40

When using the fireplace, turn down the furnace to 55°F. If you don’t, all the warm air from the furnace will go right up the chimney, wasting energy and money.

Tip #41

Add fireproof caulk where the chimney meets the wall, inside and outside.

Tip #42

When the fireplace is not in use, make sure fireplace dampers are sealed tight, and keep the glass doors closed. If you never use your fireplace, plug the chimney with fiberglass insulation and seal the doors with silicone caulk.

Insulating Your Home

Tip #43

Check insulation levels throughout your house. Measure attic insulation with a ruler, and check behind switch plates for sidewall insulation. Remember to turn off circuit breakers before removing switch plate and outlet covers.

Tip #44

Install more attic insulation. Upgrading from three inches to 12 inches, and doing proper attic sealing, can cut heating costs up to 20% and cooling costs by 10%.

Tip #45

Add pieces of batt insulation to the rim joists – the area along the top of the foundation where it meets the exterior walls.

Tip #46

If your basement is unheated, install blanket insulation in between exposed floor joists.

Tip #47

Choose the new “no-itch” or poly-wrapped insulation products. They’re much easier to handle and safer to work with – making them worth the extra cost.

Tip #48

Install additional attic insulation at right angles to the previous layer. You don’t have to use the same type of insulation – it’s fine to use batts or blankets over loose-fill, or vice versa.

 

Tip #49

When using loose-fill, be sure to distribute the insulation evenly. Any inconsistencies can reduce the insulating value.

Tip #50

Install exterior or interior storm windows; storm windows can reduce your heat loss through the windows by 25% to 50%, particularly if you have single pane windows.

Tip #51

While shopping for insulation, remember that R-value measures the amount of thermal resistance. The higher the R-value, the better the insulation.

Tip #52

Never cover attic vents or recessed light fixtures with insulation, and allow a three-inch clearance around chimneys and flue pipes to prevent overheating and avoid the risk of fire.

Tip #53

Have a leaky roof repaired and make sure your basement is waterproofed. Wet insulation is worthless.

Air Conditioning Your Home

Tip #54

If you set your thermostat a little higher during summer months, you’ll reduce your cooling costs 3-4% for each degree of adjustment. Changing the temperature from 74°F to 78°F could lower your energy bill by more than 10%.

Tip #55

Maintain your central air conditioner by cleaning the outside compressor with a garden hose (be sure to shut off power at the fuse or breaker first). Keep plantings at least one foot away for adequate airflow.

Tip #56

During late afternoon and early evening, turn off unnecessary lights and wait to use heat-producing appliances. It’s also a good idea to shade south- and west- facing windows during the hottest part of the day.

Tip #57

Plant a tree. One well-placed shade tree can reduce your cooling costs by 25%. For maximum benefit, place leafy shade trees to the south and west, and evergreens to the north.

Tip #58

Use ceiling fans to help circulate air throughout the house, and make sure your attic is properly ventilated. A ceiling fan should run counter clockwise during the summer, and clockwise during the winter.

Tip #59

Set the fan on your central air conditioner to “on” rather than “auto.” This will circulate air continuously, keeping the temperature more even throughout the house and aiding in dehumidification.

Tip #60

Make sure your window air conditioner is the proper size. It’s better to get one that’s too small than too large – a larger unit will start up and turn off more frequently and won’t do as good a job dehumidifying the air.

Tip #61

Don’t judge the efficiency of your air conditioner by the sound of the fan shutting on and off. The blower will continue to circulate cooled air throughout your home up to 15 minutes after the compressor has stopped. (The same holds true for the furnace.)

Tip #62

Raise the thermostat to about 78°F whenever you go to bed or leave the house. A programmable or Wi-Fi smart thermostat will do this for you automatically.

Tip #63

If your home can’t accommodate central air conditioning, try a whole-house fan. This device pushes hot air out through attic vents, lowering the temperature throughout your home about five degrees in less than ten minutes. Attic fans cost less than $0.25 per day to operate.

Tip #64

During the winter, remove window air conditioners and seal the windows with caulk and weather stripping. You might also want to cover the central air compressor with a tarp to keep it clean.

Weatherproofing Your Home

Tip #65

Seal doors and windows with caulk, weather stripping and plastic film. An investment of $50 in weatherproofing supplies can reduce heating costs by two to three times that much. Don’t forget the basement windows!

Tip #66

Add foam gaskets behind all outlet covers and switch plates, and use safety plugs in all unused outlets. These are prime places for outside air to leak into your home. Be sure to shut off power at the fuse box or circuit panel first.

Tip #67

Check the exterior of your home for air leaks, especially around openings for water spigots, air conditioner hoses, dryer vents and gas pipes. Use caulk or expanding foam to seal spaces.

Tip #68

If your home has a large, single-pane picture window, use heavy draperies during the winter to help keep out cold air.

Tip #69

Reflective window film can help reduce heat gain during the summer, and it will keep furniture and carpets from fading.

Tip #70

Check window panes to see if they need new glazing. If the glass is loose, replace the putty holding the pane in place. Most types of window glazing require painting for a proper seal.

Tip #71

If drafts sneak in under exterior doors, replace the threshold. If that’s not practical, block the drafts with a rolled-up towel or blanket.

Tip #72

Seal the edges of unused doors and windows with rope caulk. Don’t seal them shut permanently – you might need quick ventilation or escape during an emergency.

Tip #73

Choose the right kind of caulk for the job. Use latex or acrylic caulk inside – it’s easy to clean and more forgiving if you’re a beginner. Silicone caulk is great for outside use because it lasts longer and seals virtually any type of surface.

Tip #74

Don’t forget to weatherproof the attic access. Secure batt insulation to the back of the hatch or door, and use weather stripping to seal the opening.

Water Heating

Tip #75

Set the water heater temperature at 120°F – about halfway between low and medium. This will help save energy and prevent scalding, while keeping unhealthy bacteria from growing.

Tip #76

Install a water-saving showerhead. Don’t worry – it won’t reduce your water pressure. A family of four, each taking a five-minute shower a day, can save $250 a year in water heating costs by switching to an energy-efficient showerhead.

Tip #77

Fix leaky faucets, especially if it’s a hot water faucet. One drop per second can add up to 165 gallons a month – that’s more than one person uses in two weeks.

Tip #78

Use aerators on kitchen and bathroom sink faucets. If you have hard water, clean aerators and showerheads with vinegar regularly to reduce deposits and build-up.

Tip #79

Take showers, not baths. A five-minute shower will use about 7.5 gallons of hot water, while filling a bathtub can use up to 20 gallons.

Tip #80

If your water heater is more than 15 years old, install an insulating wrap to reduce “standby” heat loss. It’s also a good idea to insulate hot water pipes where they’re accessible.

In the Kitchen

Tip #81

Use smaller kitchen appliances whenever possible. Microwaves, toaster ovens and slow-cookers can use 75% less energy than a large electric oven.

Tip #82

Vacuum the refrigerator coils about twice a year to keep the compressor running efficiently.

Tip #83

As your mother always told you, don’t leave the refrigerator door open. Every time it’s opened, up to 30% of the cooled air can escape. The same rule holds for the oven, too.

Tip #84

Keep the refrigerator temperature about 36-38°F, and the freezer at 0-5°F.

Tip #85

Don’t overload the refrigerator. The cold air needs to circulate freely to keep foods at the proper temperature.

Tip #86

Make sure the refrigerator is level, so the door automatically swings shut instead of open. If the floor isn’t level, use shims to prop up the front of the refrigerator.

Tip #87

Don’t worry about placing hot leftovers in the refrigerator. It won’t affect energy use significantly, and cooling food to room temperature first can increase the chance of food-borne illnesses.

Tip #88

Check the seal on your refrigerator door by closing it on a dollar bill. If you can pull the bill out easily, it’s time to replace the gaskets. You can purchase a replacement kit from an appliance dealer or a home center.

Tip #89

Use your oven’s self-cleaning feature immediately after cooking, while the oven is still hot. This will reduce a lengthy warm-up time.

Tip #90

Use lids on pots and pans to reduce cooking times, and don’t put a small pan on a large burner.

Tip #91

Keep the grease plates under range burners clean to reflect heat more efficiently.

Tip #92

If your dishwasher has a “booster” water heater, use it; this will heat the water to the 140°F degrees recommended by manufacturers, while maintaining an energy-saving 120°F degrees on your water heater.

Tip #93

Run the dishwasher only with full loads, and use the air-dry cycle. The difference in energy cost between two loads per week and four loads per week can amount to $30–$40 per year.

In the Laundry Room

Tip #94

Use hot water only for very dirty loads, and always use cold water for the rinse cycle.

Tip #95

Clean the lint screen on the dryer every time you use the machine. A clogged lint screen can make your dryer use up to 30% more energy – and it can be a fire hazard.

Tip #96

Remove clothes from the dryer while they’re still damp and hang them up. This will save energy, prevent static and reduce wrinkles and shrinkage.

Tip #97

Dry one load of clothes immediately after another. This will minimize heat loss, reducing warm-up and drying times.

Lighting

Tip #98

Switch to LED light bulbs. These bulbs use 90% less energy than typical incandescent bulbs, and they last 25x longer. Replacing just 5 bulbs can save $75 a year.

Tip #99

Learn how to read the label on the bulb to make sure you are buying the bulb you need.

Tip #100

Use lighting control devices like dimmers, motion detectors, occupancy sensors, photocells and timers to provide light only when you need it.

Tip #101

Keep lamps away from thermostats; the heat produced can cause your furnace to run less than needed or your air conditioner more than needed.

Tip #102

Dust light fixtures/bulbs regularly. A heavy coat of dust can block up to 50% of the light output.

Tip #103

Use only a single bulb in a multi-socket fixture. Be sure to check the maximum wattage the fixture allows.

Tip #104

Replace an incandescent outdoor light or high-intensity floodlight with a high-pressure sodium fixture or LED bulb. The bulbs will last longer and use less energy.

Tip #105

Use solar lights to light walkways, patios and decks. The soft light will also attract fewer annoying insects.

Tip #106

Decorate with pale colors on walls, ceilings and floors. Soft tones reflect more light, so you can use lower wattage bulbs and delay turning on lights until later in the day. Using high-gloss paint can help as well.

Tip #107

When decorating for the holidays, look for LED strands of lights to save.

Other Energy Savers

Tip #108

Get rid of spare refrigerators or freezers. An extra appliance can add more than $150 to your energy bills every year, and it’s a safety hazard for small children.

Tip #109

Keep outdoor hot tubs covered when not in use. If you have a pool, use a solar cover to use the natural warmth of the sun to heat the water.

Tip #110

Use kitchen, bath, and other ventilating fans wisely; in just 1 hour, these fans can pull out a houseful of warmed or cooled air. Turn fans off as soon as they have done the job.

Tip #111

Keep the garage door closed, especially during the winter.

Tip #112

If you need a new lawn mower, consider an electric model. They’re less expensive to operate (about three cents of electricity per use), 75% quieter, and they significantly reduce toxic emissions.

Tip #113

Instead of air-polluting and expensive charcoal or propane, try an electric or natural gas grill. They’re more economical and more convenient – you’ll never run out of fuel.

Tip #114

Unplug any electrical device that’s not being used. Many appliances draw power even when turned off.

Tip #115

Place humidifiers and dehumidifiers away from walls and bulky furniture. These appliances work best when air circulates freely around them. Be sure to clean the unit often to prevent unhealthy mold and bacteria from developing.

Tip #116

If your home has no sidewall insulation, place heavy furniture like bookshelves, armoires and sofas along exterior walls, and use decorative quilts as wall hangings. This will help block cold air.

Tip #117

When you take a vacation, don’t forget to give your appliances a rest too. Turn off and unplug everything you can, set your water heater to the lowest setting and shut off the water supply to the dishwasher and washing machine.

Buying New Appliances

Tip #118

Remember that it pays to invest in energy efficiency. In some cases, the money you save in energy costs can pay back the purchase price in just a few years.

Tip #119

Always read the Energy Guide label carefully, and make sure you’re comparing “apples to apples.” Energy use can range significantly even within a single brand.

Tip #120

Choose the capacity that’s right for your family. Whether it’s a furnace or a refrigerator, it doesn’t pay to purchase a unit that’s too large or too small.

Tip #121

Replace inefficient appliances – even if they’re still working. An aging water heater or refrigerator could be costing you much more than you think. If your central air conditioner is more than 10 years old, replacing it with a high-efficiency new unit will cut your summer electric bills by about one-third.

Tip #122

Investigate new technology carefully. Some innovations, like convection ovens or argon-filled windows, may save energy and make life more convenient; others, such as commercial-grade kitchen appliances, might be merely expensive cosmetic enhancements.

Tip #123

Look for the ENERGY STAR logo. This designation from the Environmental Protection Agency means that the appliance exceeds minimum federal energy-use standards, usually by a significant amount.
