Wireless routers provide internet or network access, they are very popular for home networks allowing users to share a connection across multiple devices and computers. Wi-Fi routers are typically solid state devices and do not have moving parts, as a result their energy consumption is very low and they are usually left on 24 hours a day to provide uninterrupted internet access. We estimate that a Wi-Fi router uses 2 to 20 watts, with 6 watts being average for a wireless router.
Click calculate to find the energy consumption of a Wi-Fi router using 6 Watts for 24 hours 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.
Not much can be done to reduce power consumption of a wireless router, except to turn your Wi-Fi off if you are away for an extended period of time. Also keep in mind that your dsl or cable modem will use approximately the same amount of power as the router.
