Check how much energy your electric appliances use and how much they cost you. Space heaters look small but may use more power than you think. Make sure you accurately input how many hours per day and days per year you use your appliance.
The appliance and electronic energy use calculator from energy.gov allows you to estimate your annual energy use and cost to operate specific products. The wattage values provided are samples only; actual wattage of products varies depending on product age and features. Enter a wattage value for your own product for the most accurate estimate.
