A coffee maker or a coffee machine is a popular kitchen appliance used to brew coffee by heating up water and dripping it through ground coffee beans. Most modern coffee brewers can schedule automatic brewing by allowing users to set a time. When making coffee the coffee machine will use around 300 to 600 watts for 2 cups of coffee and 1000 to 1500 watts for 8-10 cups of coffee. We estimate that an average coffee maker will use 800 watts to produce 4 cups of coffee in 10 minutes.
Click calculate to find the energy consumption of a coffee maker using 800 Watts for 20 minutes (0.33 of an hour) a day @ $0.10 per kWh.
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.
A modern coffee maker will use approximately one watt of power in addition to the energy used for brewing. This equals to 24 watts a day and 8.76 kWh a year, which is not a significant amount of energy use. Coffee makers are energy efficient, you can save some energy by brewing a larger amount of coffee and storing it in a vacuum flask or Thermos, instead of making single cups throughout the day.
