Old refrigerators, air conditioners, and water heaters use more energy than modern, energy-efficient models.
Tip: Upgrade to Energy Star-rated appliances for long-term savings.
3. Poor Insulation and Leaks
Heat or cool air escaping through windows, doors, or poorly insulated walls makes heating/cooling systems work harder.
Tip: Seal gaps, use weatherstripping, and insulate properly.
4. Excessive Heating or Cooling
Setting thermostats too high in winter or too low in summer drastically increases energy usage.
Tip: Use a programmable thermostat and adjust temperatures when you’re not home.
5. Leaving Lights On
Many still leave lights on in empty rooms or use incandescent bulbs that consume more energy.
Tip: Switch to LED bulbs and use motion sensors or timers.
6. Water Heating Waste
