It should be pretty easy to match up with your electric bill and see what the cost would be. This unit is designed for the US power grid, but I'm sure a little googling will give you an idea what to expect for Europe and other parts of the planet. BTW, I have my primary system up 24/7. My last machine, which was an older Dell Optiplex G1 to begin with, ran almost nonstop for nearly 3 years. Only reboots were for upgrades and loss of power. Other machines are typically delegated to hibernation when not needed.
