What cost the most on your electric bill?

Our energy expenses might skyrocket when the temperatures rise. We must make our homes as energy efficient as possible to avoid hefty electric costs. Coming up with solutions to conserve energy and money might be difficult, so where do we begin? We investigate the electricity usage by common home systems, appliances, and electronics with the help of experts in the field, discover what consumes the most energy, and provide recommendations on how to make your home more energy-efficient to reduce yourenergy bill.

The following is a list of the most popular power consumption categories in a typical home: The percentage of people who use air cooling and heating is 46%, 14 per cent for water heating, appliances account for 13% of the total, 9 per cent lighting, 4 per cent for television and media equipment

Kilowatt-hours, or kWh, are the units of measurement for electricity usage. We compute daily kilowatt-hours by multiplying the hours utilized per day by the wattage of an appliance or system and then multiply that by 0.001 to get the kWh. Learn how to calculate the utilization of your appliances and systems.

Air Con and Thermal

Your HVAC system, as your major source of comfort from high external temperatures, consumes the most energy of any single appliance or system, accounting for 46 per cent of theelectricity use of the average U.S. home. An average central HVAC unit consumes roughly 3500 watts and runs for 10-15 minutes every two to three hours. Your HVAC would use roughly 28-63 kWh in 24 hours, resulting in 850-1,950 kWh in a month, depending on how efficient your unit is.

Heating Water

Your water heater is another often utilized item that accounts for 14% of your home’s energy use. A typical heater requires 4500 watts and runs for around 3 hours per day, totalling 13.5 kWh per day or 405 kWh per month. 

Consumer electronics

Consumer electronics account for roughly 13% of the average power cost. These key appliances include a refrigerator, water, and dryer, electric oven and stove, and dishwasher.

  •         Refrigerator: A typical refrigerator consumes 225 watts, and if you use it all day, you’ll consume 162 kWh every month.
  •         washers and dryers: The energy used by washers and dryers accounts for around 5% of the total energy used in your home. The total power consumption of these items is 3045 watts. Your laundry machines would use roughly 91 kWh per month if you used them for one hour each day. 
  •         Stove and Electric Oven: Using an oven at 2,500 watts and a stove at 1,500 watts on medium-high heat for one hour each day results in 75 kWh and 45 kWh per month, respectively. These gadgets, especially your oven, can heat your home and put a strain on your air conditioner. 
  •         Dishwasher: 3 watts is the typical dishwasher’s power consumption. That’s almost 10 kWh per month if used for one hour each day. Because your dishwasher can heat your home, it can also affect how hard your air conditioner has to work.


Lighting consumes approximately 9% of the energy used in an average household. The energy consumption of light bulbs differs depending on bulb type and usage. A 100-watt incandescent bulb used around 0.2 kWh per day, or 6 kWh per month when left on for two hours each day. When you multiply that by 50 lights in the house, you get 300 kWh per month. 

Electronics like television and media equipment consume little electricity for example if we spend five hours watching TV every day and engage in 6.3 hours of video games per week, this equates to around 55 kWh per month used by these devices.

In a nutshell, the type of appliances you use determines yourenergy bill. Knowing the appliance and gadgets that run up your electricity bill will enable you to manage and reduce your energy use, and make your home more energy-efficient to curb your electricity costs.
