Energy Usage Research on IoT and other Electronic Devices


Although there are many articles and published papers on energy consumption related to computer equipment and electronic devices, it’s almost impossible to find detailed or exact energy usage profiles based on environment, type of use and specifications. Here, you will find both: actual measurements (not averages or estimates) and also the specifications of the devices, which can help with comparison and identification.

Why these measurements are Useful and Important

For IT / Engineers – They can assist with Wattage or energy calculations for complex or basic systems, where battery backups (UPS), heat dissipation / cooling, and purchasing considerations can be made by using the observed energy profiles.
Off-The-Grid Enthusiasts For those who love to play around with Generators, Inverters, Solar panels and batteries. Knowing the energy consumption will help you with calculations.
Homeowners – Learn and understand what your devices are doing and how it will affect your power bill. In the energy profiles for desktop computers page, you can clearly see how some devices that are off use quite a bit of energy. Also, a computer infected with a Virus will use almost 2.5 times as much energy when the CPU runs at 100%.
Environmentalists – Being conscious about how we use our devices and making small adjustments to our behaviors, such as the electronics we buy, how we use them, how we maintain them, or being aware of the different technologies that are environmentally friendly and have low energy usage, can have a great impact on the environment.

Please note: More devices are added monthly, so please make sure to keep tuning in.


  • Testing Procedures:
    The device was powered on and allowed operate normally. A power measurement was then taken. An average may be used if the energy consumption was not consistent.
