1. Upgrade Heating & Cooling Practices

Heating and cooling account for up to 50% of home energy use. You can cut costs by:

  • Installing ceiling fans to improve air circulation in summer.
  • Replacing filters in your furnace and air conditioning systems.
  • Turning your thermostat down at night or when away. Lowering it by just oC reduce your heating bill by up to 10%.
  • Using programmable thermostats to manage temperatures more efficiently.

2. Install a Tankless Water Heater

Tankless water heaters provide hot water only when needed, reducing standby energy losses. They deliver a continuous supply of hot water while cutting energy waste.

3. Replace Incandescent Lights

Switch to LED or CFL bulbs. They use 75% less energy and last much longer than traditional bulbs. Bonus: they produce less heat, keeping your home cooler in summer.

4. Seal and Insulate Properly

Sealing gaps around windows, doors, and attic access points reduces drafts and improves comfort. Use caulk or foam around baseboards, vent pipes, and outlet covers. Proper insulation also improves indoor air quality and reduces energy bills.

5. Use Water-Efficient Fixtures

Install low-flow shower heads and dual-flush or vacuum-assist toilets. Older toilets can use up to 3.5 gallons per flush — modern models reduce this by half or more, saving thousands of gallons annually.

6. Use Appliances Wisely

  • Run full loads in your washer or dishwasher.
  • Unplug chargers and electronics when not in use.
  • Opt for ENERGY STAR-rated appliances.
  • Keep your refrigerator away from heat sources.

7. Embrace Natural Light (Daylighting)

Install skylights or light tubes to brighten rooms without flipping a switch. Use light shelves and clerestory windows to bounce daylight deeper into the home.

8. Insulate Windows and Doors

  • Apply weatherstripping and install storm windows.
  • Use thermal curtains at night.
  • Repair or replace rotted window frames.

9. Cook Efficiently

Use pressure cookers, convection ovens, and lids to reduce cooking time. Microwave ovens use 80% less energy than traditional ovens — a small change with big returns.

  • Clean the lint trap before every dryer cycle.
  • Hang dry clothes outside only .
  • Always wait for a full load before washing.
