Energy usage fluctuates based on two main factors:
Devices and appliances used in your home
Large appliances like air conditioners, heaters, refrigerators, and washers/dryers consume significant amounts of energy.
Older or inefficient appliances can use more energy than newer, energy-efficient models.
Seasonality and weather in your city
Even if you keep your thermostat at the same temperature all year, energy usage spikes in extreme weather.
In summer, air conditioning works harder; in winter, heating systems run longer.
Common household energy usage breakdown (U.S. averages):
The US Energy Information Administration gives us some rough percentages that are helpful for understanding where electricity is going:
Air conditioning and heating: 54% of total energy use
Appliances and electronics : 23% of total energy use
Water heating: 16% of total energy use
Refrigeration: 4% of total energy use
Lighting: 4% of total energy use
Other potential culprits
Pool pumps and heat pumps
Extra refrigerators or freezers
Old, inefficient appliances
How to Reduce Your Energy Usage
Improve efficiency
Use programmable thermostats to reduce heating/cooling when you’re away.
Manage heating & cooling
Seal windows and doors to prevent air leaks.
Use ceiling fans to circulate air.
Adjust thermostat settings seasonally.
By identifying what’s driving your high usage and making small changes, you can significantly lower your energy bills over time.
