Do you actually know how much electricity you use per year? On average, 1,440 kilowatt hours of electrical energy are generated per capita per year.
This number decreases as household size increases because many appliances such as the refrigerator are shared.
Therefore, on average across the country, a single-person household consumes around 1,900 kilowatt hours of electricity per year, a two-person household around 2,890 kWh, a family of three 3,720 kWh and a four-person household 4,085 kWh.
