Simple strategies to save energy in your home

The easy way to save energy at home is to make small changes in habits and to perform some basic regular maintenance. Here’s a comprehensive list of energy-saving strategies to work into your daily life — summer, winter and year-round.

Rethink how you use your household appliances

In most homes, appliances are the major drivers of energy use. These simple adjustments are great ways to save energy:

Energy-Saving Tip 1: Wash only full loads of dishes and clothes.

ways to save energy - wash only full loads of laundry
Your clothes washer and dishwasher are designed to run most efficiently with full loads. And more than that, if you run them only when full, you run them less often, which really cuts energy use.

Energy-Saving Tip 2: Wash clothes with cold water.

energy saving tip - wash clothes in cold water
Clothes washers and laundry detergents are designed to work efficiently with cold water. If you only wash with hot water when you need to disinfect, you could save $60 or more a year.

Energy-Saving Tip 3: Keep your appliances clean.

energy saving tip keep appliances clean
Every appliance runs more efficiently when filters are clear of dust and door seals are free of gunk.

Energy-Saving Tip 4: Keep the oven door closed while cooking.

ways to save energy tip - keep oven door closed
The temperature in your oven can drop 25 degrees or more every time you open the oven door.

Energy-Saving Tip 5: Don’t stand in front of an open refrigerator door.

energy saving tip - dont stand in front of open fridge
The longer the fridge door is open, the harder the appliance has to work to maintain a cool temperature. Decide what you want in advance to minimize the amount of time the fridge or freezer door is open.

BONUS TIP: Automate your appliances with smart assistants.

energy saving tip - use smart assistants
Smart assistants make it possible to control your appliances, even while away. With smart assistant routines, you can control your appliances and turn them off remotely to save time and energy.

Get help from Mother Nature to save energy at home

Sometimes the best way to save energy is simply not to use it at all. Here are some energy-saving tips that involve letting nature take its course:

Energy-Saving Tip 6: Air-dry clothes.

energy saving tip - air dry clothes
There’s nothing quite like the smell of sheets, towels and clothes that have been dried out in the fresh air. Consider air-drying clothes on an old-fashioned clothes line or even hanging them inside the house. Alternatively, use an energy-efficient dryer.

Energy-Saving Tip 7: Air-dry dishes instead of using your dishwasher’s drying cycle.

ways to save energy - air dry dishes
Select the air-dry option on your dishwasher. Crack it open after the rinse cycle and your dishes will dry without a single kilowatt being used. You’ll also save energy by keeping your kitchen cooler.

Energy-Saving Tip 8: Open curtains facing the sun.

energy saving tip - open curtains facing the sun.
Even the most efficient windows allow energy to pass through. Sunlight beating down all day can really heat your interior. At night, close curtains and blinds to create another layer of insulation. During the day, let the light shine in during cold weather, but block it when it’s hot.

BONUS TIP: Bring in more natural light with mirrors and bright walls.

energy saving tip - bring in natural light with mirrors and paint
Make the most of natural light with bright decorating choices, strategically placed mirrors and putting workspaces near windows so that you don’t need to keep the lights on all day.

Adapt your daily energy habits

Changing your habits will have a major effect on your power use. When thinking about ways to save energy at home, putting thought into the little things has a big impact.

Energy-Saving Tip 9: Switch out incandescent lights.

energy saving tip - turn off lights when not in the room
Traditional light bulbs waste 95% of the energy they use giving off heat, with only 5% going toward light. Switch them out or use them sparingly. Leaving them on for long periods is highly wasteful.

Energy-Saving Tip 10: Take shorter, cooler showers.

ways to save energy tip - take shorter showers
Cut the energy used by your hot water heater by taking shorter, cooler showers. Consider that a typical shower uses 2.5 gallons of hot water a minute. Cutting your daily shower by four minutes will save 3,650 gallons a year.

Energy-Saving Tip 11: Turn off electronics and appliances when they’re not in use.

energy saving tip - turn off electronics when not in use
Leaving your computer on while idle wastes electricity and shortens the life of your machine. The same goes for televisions, printers and other electronics. If you see the indicator light on, you’re burning power needlessly.

BONUS TIP: Unplug battery chargers when not in use.

energy saving tip - unplug battery chargers when they are fully charged
Many devices, including battery chargers, draw power continuously, even when not in use. Cut so-called vampire power consumption and save a bundle.

Adjust your device and appliance settings to save energy at home

If you’re willing to be a little flexible with the thermostat and be aware of when and how you’re using energy, you can easily reduce waste.

Energy-Saving Tip 12: Adjust your thermostat according to the time of day.

ways to save energy - install programmable thermostat
Reduce energy use at home by adjusting the thermostat day and night, as well as when you’re away or at work.

Energy-Saving Tip 13: Lower the thermostat on your water heater to 120 F.

ways to save energy - lower your thermostat on your water heater.
Heating water is the third-largest use of energy in most homes. Turning down the thermostat a few degrees cuts consumption without reducing comfort.

Energy-Saving Tip 14: Set your computer to sleep or hibernate mode.

ways to save energy - set computers to sleep or hibernate mode You use much less energy than by leaving your computer on with a screen saver.

Energy-Saving Tip 15: Avoid using the rinse-and-hold setting on your dishwasher.

ways to save energy tip - avoid using rinse hold setting on dishwasher
This setting uses 3 to 7 more gallons of water than a regular wash cycle.

BONUS TIP: Raise your room temperature slowly to keep your bill lower.

ways to save energy tip - raise temperature slowly
If you have a heat pump, quickly raising its temperature activates the heat strip, which uses more energy.

Consider using an energy-saving alternative

Get chores done without plugging something in. Think of a broom instead of a vacuum. And if you do use an appliance, right-sizing to a smaller appliance helps. A hand-held mini-vac uses less energy than your full-size upright.

Energy-Saving Tip 16: Use a microwave or toaster oven instead of your conventional oven.

ways to save energy tip - use microwave to cook leftovers
You’d be surprised how much you can cook, beyond just warming leftovers, in these energy-saving appliances.

Energy-Saving Tip 17: Use the dishwasher instead of washing by hand.

energy saving tip - use dishwasher instead of hand washing
An electric dishwasher doesn’t just save effort; it saves energy, using 5,000 fewer gallons of hot water per year compared to washing by hand.

BONUS TIP: Use your electric kettle to boil water instead of a microwave.

energy saving tip - use electric kettle
It focuses energy on efficient heating, boiling water faster with less electricity.

Make small investments to achieve long-term results

Here are a few things you can buy that increase the energy efficiency of your current appliances. They don’t cost much money and don’t require expert installation, which make them easy ways to save energy at home.

Energy-Saving Tip 18: Plug home electronics into power strips.

ways to save energy tip - plug electronics into power strips
Turn the power strips off when equipment is not in use. You’ll stop these devices from using energy when idle with one convenient switch.

Energy-Saving Tip 19: Install low-flow shower heads.

ways to save energy tip - install low flow shower headsy
Shower heads that give good water pressure with fewer gallons per minute (under 2.5 gpm are best) will cut water and energy consumption.

Energy-Saving Tip 20: Add aerators to your faucets.

ways to save energy tip - add aerators to faucets
Choose aerators with a flow rate of no more than 1.0 gpm for maximum savings.

BONUS TIP: Add an insulating blanket to older water heaters.

ways to save energy - insulating blanket for water heaters
These can reduce standby heat loss by 25%–45% and save about 4%–9% in water heating costs.

Switch to energy-efficient appliances and electronics

Modern appliances are dramatically more efficient than they were even 10 years ago. Whether in your kitchen, your laundry room or your office, ENERGY STAR® options make it easy to compare and find what will work best and use the least electricity.

Energy-Saving Tip 21: Use ENERGY STAR-qualified CFL and LED bulbs.

way to save energy tip - use energy star cfl and led bulbs
LEDs and CFLs use a fraction of the energy of traditional incandescent bulbs — and they last longer.

Energy-Saving Tip 22: Replace older home appliances with energy-efficient models.

ways to save energy - replace old appliances with energy star
From air conditioners to coffee makers, you’ll find multiple ways to save energy and money by buying new ENERGY STAR® products.

Energy-Saving Tip 23: Use energy-efficient entertainment and home office electronics.

energy saving tip - use energy efficient electronics
Computers, televisions, game systems and printers make big demands on home energy use as well. These also come with ENERGY STAR® ratings to help you make efficient choices.

Prevent leaks in your house

It isn’t enough to buy energy-efficient products and use them with care. You may still be wasting energy if your home isn’t well insulated. Here are the common problem areas in most homes:

Energy-Saving Tip 24: Insulate heating ducts.

way to save energy tip - insulate heating ducts
Some 20%-30% of warm or cool air in your home is lost to leaky air ducts.

Energy-Saving Tip 25: Seal air leaks.

ways to save energy tip - seal air leaks
Sealing air leaks around doors, windows and gaps where gas, water and electricity come in can save between 5% and 30% of your energy use, according to Energy.gov.

Energy-Saving Tip 26: Insulate hot-water pipes.

ways to save energy tip - insulate hot water pipes
Keeping water hot while traversing pipes by adding insulation can raise its temperature at the point of use between 2 and 4 degrees Fahrenheit. You can turn down your hot water heater without sacrificing comfort.

Maintain your home and appliances to keep saving energy

Clean appliances and a clean home will keep everything running at optimum energy efficiency. Less dust in the air is healthier, and less gunk in your systems means they run smoothly and use less electricity.

Energy-Saving Tip 27: Clean your air ducts.

energy saving tip - clean your air ducts regularly
In a typical house, you can save 25%-40% on the energy your HVAC systems use by cleaning your air ducts regularly.

Energy-Saving Tip 28: Clean/replace filters in your furnace.

ways to save energy tip - clean or replace furnace filters
EnergyStar.gov recommends changing the air filters every three months. A dirty filter slows down airflow and makes the system work harder.

Energy-Saving Tip 29: Clean the dryer lint filter regularly to keep your dryer running efficiently.

ways to save energy tip - clean dryer lint filter
Cleaning the filter isn’t enough. Use the long nozzle on your vacuum to clean the ventilation tubing.

Prevent energy waste when you’re away from home

When you aren’t living in your house for a significant length of time, you can really save energy by adjusting your systems and disconnecting all but critical appliances. Check out these energy-saving tips for when you’re away from home:

Energy-Saving Tip 30: Turn off your water heater if you plan on leaving home for a few days.

energy saving tip - turn off water heater if leaving home for many days
Most models will quickly reheat the water when you return home.

Energy-Saving Tip 31: Install a timer for your water heater.

ways to save energy - install timer on water heater
You don’t have to go out of town to turn off your water heater. Timers can switch it off after your morning shower and switch it back on again just before you get home, saving the waste of it running all day.

BONUS TIP: Turn off your appliances from anywhere with smart plugs.

energy saving tip - use smart plugs

Smart plugs allow you to remotely control appliances, lights and HVAC systems in your house, switching them off when you’re out and then back on when you return.

Emma Miah - 8/25/2018

Last year, I spent some considerable time resolving my girlfriend’s utility bills due to a whole host of complicated issues such as billing for incorrect meter, non-reconciliation of payment, final payment notices plus interest. Eventually all resolved with nothing to pay, but took 5 months of calls, emails and documentation. Thankfully, my girlfriend had all the documentation from the specialist who had visited 6 months prior to confirm meter for the premises and the correct meter number.

We also had an issue with outstanding gas debt (caused by her ex). Resolved the debt through a re-payment plan per month, agreeing fixed amount per month and last payment date – especially as she moved to a new (modern) premises, so we needed agreement to tie up loose ends.

    Constellation Community Team - 8/29/2018

    Hi Emma, it seems like you’ve been diligently working to reduce your energy costs and cutting down debt! You’ve been making great energy decisions. Another way you might be able to bring stability to your energy budget could be through a Constellation fixed-rate natural gas plan.
