Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for Raspberry Pi. It's 100% free, no registration required.

My searching efforts have failed when trying to find this. On average, how much energy does the raspberry pi consume in 24 hours ( minimal usage vs max usage in a day AND usb vs micro usb powered)?

You are interested in the wattage en.wikipedia.org/wiki/Watt If you look around you'll find various figures, eg: kaibader.de/my-new-raspberry-pi claims 3-3.5 W for a model B. –  goldilocks Feb 19 '13 at 23:57

So, yeah, probably not more than:

4 W*24 h = 96 Wh (I guess that's 345.6 kJ) (note this is energy, not a power)

and likely not less than half that if you get the power down to 2 W. This is for a Raspberry Pi model B, the model A consumes even less power.

Even at relatively high electricity prices you are looking at < $0.02 per day of running the box.

Note, power consumption has been changing (for the better) with improvements in the software, because it's possible for the OS to power down some blocks of the machine when they are idle or perhaps if explicitly turned off.

Also please realize that although it's very little power, if you are buying a solar panel, battery, charge regulator, etc. just to run the pi, you are spending a lot more on power hardware than you are spending on computing.

Enjoy!
