The biggest users of electricity in a home can vary depending on factors such as the size of the home, the number of occupants, and the climate. However, some common appliances and systems that use the most electricity in a home are:

• Heating and cooling: This is the largest electricity consumer in the average household, accounting for 45-50% of energy use.
• Water heater: If you have an electric water heater, then it is likely the second biggest energy consumer in your home, accounting for about 14% of energy use.
• Appliances: Home appliances account for about 13% of an average homes energy consumption. Some of the most energy-hungry appliances include washing machines, dishwashers, and tumble dryers. Refrigerators also use a significant amount of energy, with an average refrigerator using about 162 kWh per month.
• Lighting: Lighting accounts for about 9% of a typical homes energy use.

Other appliances and systems that can consume a significant amount of electricity in a home include televisions and media equipment, dehumidifiers, hot tubs, and devices in idle power mode. To reduce electricity consumption and save money, homeowners can take steps such as upgrading to more energy-efficient appliances, using power strips to cut off power to multiple electronics at once, and adjusting the temperature settings on heating and cooling systems.
