Electricity usage of a DVR

Digital video recorders or tv boxes can be very energy inefficient and cost you a lot of money. Natural Resources Defense Council published a study in 2011 which indicates that a typical household set-top box configuration with one HD-DVR & one HD Set-Top Box uses an average of 446 kWh a year which is around 51 watts. A typical HD-DVR will use 32 watts of power when on and 31 watts of power when in light sleep, while the HD-Client will use 20 watts of power when on and 19 watts when in light sleep.

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.

The reason why DVRs can use so much energy is because they are never really off, the sleep mode on DVRs or cable boxes is not effective at reducing energy use. DVRs require to be on because they are used to record scheduled tv programs. The only way to reduce the energy consumption of a DVR is to unplug the device completely. Newer DVR models may reduce energy consumption by dropping active usage to 31 watts for a DVR & Set-Top Box and down to 17 watts for both when in light sleep mode.
