In addition to all that was mentioned by Sayda above leaving doors and windows widely open during days and nights while using an air conditioning system for heating or cooling will significantly contribute in raising the house energy consumption.
Household electricity consumption can exceed kilowatt-hours per month due to a combination of high-power appliances, inefficient energy use, and lifestyle factors. Heating and cooling systems, electric water heaters, and large refrigerators are major culprits, especially in extreme climates. Additionally, modern homes are increasingly filled with energy-hungry devices such as EV chargers, home offices with multiple electronics, and smart home automation. Poor insulation and outdated appliances further drive up consumption. Ultimately, a mix of technology, habits, and home infrastructure dictates energy demand, sometimes pushing it well beyond expected levels.
A lot depends on the technology used; for example, an older electric resistance clothes dryer may use 800 kWh of electricity per year, while a vent-less heat pump dryer can use 125 kWh per year or less. At the same time, an efficient home with a renewable energy supply, heat pumps for cooling AND heating, and an electric vehicle, may slightly increase electric consumption over the average, but can eliminate greenhouse has emissions from operations (excluding maintenance), eliminating the air pollution from fossil fuel burning.
