Solar and Green PowerElectricity usage of an Air Conditioner A room air conditioner is used to cool an apartment or a single room, they are often placed inside of a window and bring in outside air while cooling it. Single room air conditioners come in different sizes and use from 500 to 1500 watts. Click calculate to find the energy consumption of a room air conditioner using 1000 Watts for 3 hours a day @ $0.10 per kWh. Hours Used Per Day: Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5) Power Use (Watts): Enter the average power consumption of the device in watts. Price (kWh): Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents. To find an exact price check your electricity bill or take a look at Global Electricity Prices. Decreasing the use of an air conditioner will help lower costs, cooling is generally expensive and there are not many options to save money without increasing your temperature.
