How Do You Save Energy at Home?
Energy use varies by home size, climate, equipment, and daily routines. Understanding these differences can help you identify which improvements deserve attention first.
Track Your Home Energy Use
Before making major changes, review your electricity bills and compare monthly energy use in kilowatt-hours (kWh). Look for seasonal increases that may indicate heavy heating or cooling demand. Smart meters, energy-monitoring plugs, and a basic home energy assessment can help identify inefficient appliances and unnecessary electricity consumption. Use these findings to prioritize changes that address your household's actual energy needs.
Heating and Cooling as the Biggest Opportunity
Heating and air conditioning often account for the largest share of home energy use. Small thermostat changes, clean filters, sealed ducts, and better insulation can reduce strain on your system while keeping rooms more evenly comfortable.
Hot Water, Lighting, Appliances, and Standby Power
Water heating, lighting, refrigerators, laundry machines, TVs, computers, and chargers all add up. A few daily decisions, such as shorter hot showers or switching off electronics, can save energy at home without affecting your routine much.
No-Cost Habits, Low-Cost Fixes, and Long-Term Upgrades
Think in layers. Start with no-cost habits, then add low-cost DIY improvements, and save major upgrades for aging equipment. This approach helps reduce energy bills steadily while avoiding unnecessary spending on projects with limited payoff.
How Can You Reduce Heating and Cooling Energy Use?
You can reduce heating and cooling energy use by controlling thermostat settings, maintaining equipment, improving airflow, and limiting heat gain or loss through windows. These steps usually deliver the biggest savings.
Set Your Thermostat for Comfort and Savings
In winter, around 68°F while you're home and awake can be a starting point for many households. With conventional heating systems, lowering the thermostat while sleeping or away may reduce energy use. In summer, choose the highest comfortable cooling setting. If your home uses a heat pump, avoid large heating setbacks unless the thermostat is designed for that system, as auxiliary heating may increase electricity consumption.
Use a Programmable or Smart Thermostat
A programmable thermostat follows your schedule, while a smart model can learn patterns and adjust automatically. Smart thermostat energy savings are strongest when the device prevents heating or cooling an empty home and avoids extreme manual settings.
Replace HVAC Filters and Schedule Regular Maintenance
Check filters monthly and replace them according to the manufacturer’s guidance, often every one to three months. A clogged filter restricts airflow, makes equipment work harder, and can reduce comfort. Schedule seasonal HVAC service for better performance.
Keep Vents Clear and Use Ceiling Fans Correctly
Move furniture, rugs, and curtains away from supply and return vents. In summer, ceiling fans should push air downward. In winter, reverse the fan at low speed to circulate warm air without creating a chill. Turn ceiling fans off when the room is unoccupied, as fans improve personal comfort rather than directly cooling the room.
Manage Sunlight With Curtains, Blinds, and Shade
Open sunny curtains on cold winter days to gain natural warmth, then close them at night. In summer, close blinds during the hottest hours, especially on west- and south-facing windows, to reduce cooling demand.
Seal Drafts and Improve Insulation Before Energy Escapes
Air leaks make HVAC systems run longer because conditioned air escapes and outdoor air sneaks in. Learn to seal drafts around windows and doors before spending on bigger equipment upgrades.
Weatherstrip Doors and Caulk Window Gaps
Use weatherstripping where parts move, such as door edges and operable windows. Use caulk for stationary gaps around frames, trim, and small cracks. On a windy day, check for drafts around doors and windows with a damp hand or a purpose-built draft detector. For a more thorough assessment, consider a professional blower door test.
Add Door Sweeps and Use Window Coverings
Door sweeps block gaps at the bottom of exterior doors, where cold air often enters. Thermal curtains, cellular shades, or window film can improve comfort near glass, especially in older homes with single-pane windows.
Seal Visible Ductwork Leaks
Leaky ducts can send heated or cooled air into attics, crawl spaces, basements, or wall cavities. Seal accessible duct joints with mastic or approved foil tape, not standard cloth duct tape, which can fail over time.
Consider Attic, Wall, or Crawl Space Insulation
If rooms stay uncomfortable after sealing leaks, insulation may be the next step. Attics are often the most cost-effective place to improve first. A qualified contractor can check depth, air sealing, ventilation, and moisture concerns.
How Can You Save Energy With Lighting and Electronics?
If you are learning how to conserve energy, lighting and electronics are practical areas to improve because small daily changes can reduce unnecessary electricity use.
-
Switch to LED bulbs. LEDs use far less electricity than old incandescent bulbs and last much longer. Replace high-use bulbs first, such as kitchen, living room, porch, bathroom, and hallway lights.
-
Use task lighting. A desk lamp, under-cabinet light, or reading lamp can use less energy than lighting a whole room. This is especially helpful in home offices and kitchens.
-
Reduce phantom energy with smart power strips. Phantom energy comes from devices drawing electricity while “off” or idle. Smart strips can cut power to TVs, game consoles, printers, and chargers when they are not needed.
-
Unplug chargers after use. Phone, tablet, laptop, and tool chargers can still draw small amounts of power when left plugged in. The savings are modest, but the habit is easy.
-
Use timers, dimmers, and motion sensors. These controls help outdoor lights, closets, garages, and rarely used rooms turn off automatically. They also reduce the chance of lights being left on overnight.
-
Choose efficient settings. Enable sleep mode on computers, monitors, printers, and smart TVs. Shorter screen timeout settings can reduce electricity use without changing how you use the device.
-
Buy ENERGY STAR electronics when replacing old models. Certified products are designed to use less energy during operation and standby, helping reduce waste over the life of the product.
Kitchen, Laundry, and Water Heating Habits That Save Energy
Kitchen, laundry, and hot water habits matter because they combine electricity, gas, and water use. A few practical changes can trim waste without making daily chores harder.
-
Lower your water heater temperature. For many households, setting the water heater to around 120°F can reduce standby heat loss and scalding risk. However, homes with special health considerations or equipment requirements may need different settings. Always follow the manufacturer's instructions and relevant safety guidance.
-
Install low-flow showerheads and faucet aerators. These fixtures reduce hot water use while maintaining usable pressure. Less hot water means less energy needed to heat it.
-
Air-dry when practical. Clotheslines, drying racks, or the dryer’s lower-heat setting can reduce electricity use. Clean the lint screen every load so the dryer runs efficiently when you do use it.
-
Run full loads. Dishwashers and washing machines are most efficient when full but not overloaded. Use eco cycles when available, because they often use less water and heat.
-
Set refrigerator and freezer temperatures correctly. Aim for about 35°F to 38°F in the fridge and 0°F in the freezer. Keep coils clean and door seals tight.
-
Insulate hot water pipes and older water heaters. Foam pipe insulation helps hot water stay warm as it travels to faucets. If your older tank-style water heater is approved for a blanket, insulation can reduce standby heat loss and help the system work less often.
Which Home Energy Upgrades Are Worth Considering?
Energy-saving upgrades are worth considering when simple habits and DIY fixes no longer solve comfort problems or when old equipment is near replacement. Compare upfront cost, savings, reliability, and long-term home plans before investing.
ENERGY STAR Appliances and Equipment
When major appliances wear out, compare ENERGY STAR appliances and equipment for refrigerators, washers, dishwashers, heat pumps, and water heaters. The best choice depends on household size, local utility rates, rebates, and how often you use the appliance.
Smart Thermostats and Smart Home Controls
Smart controls can automate temperature, lighting, and plug loads. The biggest value comes from consistency: fewer forgotten lights, less heating or cooling while away, and easier scheduling. Look for compatibility with your HVAC system before buying.
Home Energy Monitors and Smart Plugs
Energy monitors and smart plugs show which devices use the most power. That data can reveal inefficient appliances, always-on electronics, or unusual spikes. They are useful if your bill rises and you need clearer answers.
How Can Home Battery Storage Help Manage Energy Use?
Reducing unnecessary electricity use should come first. For households with solar panels, a battery backup for home system can provide an additional way to manage electricity. It can store surplus solar energy for later use, increase solar self-consumption, and supply backup power during outages. Actual savings depend on electricity tariffs, solar generation, and system efficiency.
For homeowners considering expandable storage alongside these energy-saving improvements, the Anker SOLIX E10 Whole-Home Backup combines battery storage, solar charging, and smart energy management.
Key features include:
-
