How to Reduce Your Energy Usage Without Making Big Lifestyle Changes

Audit Your Home’s Energy Use

The first step is to understand where and how you are using the most energy in your home.

  • Do an energy audit to find out what systems and appliances use the most energy. Areas to look at include heating and cooling, lighting, major appliances like the refrigerator and clothes washer/dryer, and electronics.

  • Check your utility bills and look for spikes in energy usage. This can help identify when and where you are using the most energy.

  • Use an energy monitor like Sense or Emporia to get real-time data on your home’s energy use. These devices track energy use down to the individual appliance.

  • Once you know where you use the most energy, you can focus on making improvements in those areas first.

Implement No-Cost Habit Changes

Simple habit changes in your daily routine can reduce energy waste and cost nothing.

  • Turn off lights when not in use. Install motion sensor lights in high traffic areas.

  • Unplug phone chargers, laptops, and other electronics when not in use. Consider getting smart power strips.

  • Lower the thermostat a few degrees in winter, raise it in summer. Wear layers to stay comfortable.

  • Run full loads in the washer, dryer, and dishwasher. Air dry dishes instead of heat drying.

  • Open windows on nice days instead of relying on air conditioning. Close when weather is very hot/cold.

  • Change HVAC air filters monthly for maximum efficiency.

  • Close shades and blinds during the day to keep heat out in summer. Open them on cold days to let warmth in.

Seal Air Leaks and Add Insulation

Sealing hidden air leaks around your home and adding insulation can lead to 10-20% savings on energy bills.

  • Perform an air leakage test to identify problem areas. Use caulk and weatherstripping to seal openings.

  • Add insulation to the attic, walls, and crawl spaces. Blown-in fiberglass is an easy DIY upgrade.

  • Replace old windows and doors with new energy efficient models. Look for double/triple pane glass and argon/krypton gas filled.

  • Have an energy audit done by a professional auditor. They can find hidden issues and recommend insulation upgrades.

  • If renovating, choose spray foam insulation. It air seals and insulates in one step.

  • Proper insulation keeps your home comfortable year-round while using less energy for heating and cooling.

Upgrade Old/Inefficient Appliances

Replacing aging refrigerators, washers, dryers, and other appliances with new ENERGY STAR models can save over 20% on energy use.

  • When old appliances break down, replace instead of repairing. New units are dramatically more efficient.

  • Look for the ENERGY STAR rating when shopping for new appliances. These models meet strict energy efficiency criteria.

  • Refrigerators made before 2000 use up to 3x more energy than new models. Upgrade fridges over 10 years old first.

  • Washers/dryers with moisture sensors use less energy by preventing over-drying. Front load washers also use less water.

  • Dishwashers that heat water internally are more efficient than ones relying on your home’s hot water.

  • Visit to compare energy use of different appliance makes and models.

Install Smart Home Technology

Smart thermostats, plugs, and lighting controls reduce energy waste through automation and scheduling.

  • Smart thermostats like the Nest or Ecobee self-adjust to save energy while keeping your home comfortable. They also allow remote temperature control via smartphone.

  • Smart plugs like the TP-Link Kasa let you control electronics remotely. Turn off appliances when not in use to prevent phantom load.

  • Smart light switches like the Philips Hue enable voice activated lighting. Motion sensors turn lights off in vacant rooms. Set schedules to turn off lights at bedtime.

  • Smart sprinkler controllers like Rachio monitor weather and soil condition to optimize watering schedules. This prevents over-watering.

  • Smart home tech works in the background to cut energy use while maintaining comfort and convenience.


With a few DIY upgrades and habit changes, you can dramatically reduce home energy use without fundamentally changing your lifestyle. Start by understanding your usage patterns through monitoring. Then implement no-cost habit changes like turning off lights and adjusting the thermostat. Sealing air leaks and adding insulation keeps heating/cooling costs down. Replace old appliances and install smart home technology to maximize efficiency. A few simple tweaks can lead to major energy savings over time.
