6 devices that consume more energy than air conditioners: save energy

By Lesia

It’s true that while air conditioners consume a significant amount of energy, several other household devices can use even more. Here’s a breakdown of some of the top energy consumers:

High-Energy Consumption Devices:

  • Space Heating:
    • Electric space heaters and furnaces are major energy hogs. They convert electricity directly into heat, which requires a lot of power.  
  • Water Heating:
    • Water heaters, especially electric ones, use a substantial amount of energy to heat water for showers, baths, and laundry.  
  • Clothes Dryers:
    • Electric clothes dryers generate heat to dry clothes, which is a very energy-intensive process.  
  • Ovens and Stoves:
    • Electric ovens and stoves require a lot of energy to heat up and maintain high temperatures for cooking.
  • Hot Tubs/Spas:
    • These devices require constant heating to maintain warm water temperatures, leading to very high energy consumption.
  • Electric Vehicles (EVs) Charging:
    • While not a traditional household appliance. Charging an EV, especially with a level 2 charger, will use a very large amount of electricity.

Key Factors in Energy Consumption:

  • Heat Generation: Devices that generate heat, such as those listed above, tend to consume the most energy.  
  • Duration of Use: Even devices with moderate wattage can consume a lot of energy if they’re used for extended periods.

Tips for Saving Energy:

  • Upgrade to Energy-Efficient Appliances: Look for ENERGY STAR certified appliances.
  • Reduce Water Heating Costs: Lower your water heater temperature, install a low-flow showerhead, and insulate your water heater.
  • Air Dry Clothes: Whenever possible, air dry your clothes instead of using the dryer.
  • Use Cooking Appliances Efficiently: Use the microwave instead of the oven when possible, and avoid preheating the oven for extended periods.  
  • Smart Thermostats: Utilize smart thermostats to better regulate heating and cooling.  
  • Insulation: Ensure proper home insulation to reduce the need for heating and cooling.  

By being mindful of these energy-consuming devices and implementing energy-saving strategies, you can significantly reduce your energy consumption and save money on your utility
