Welcome aboard!
Europe with the actual rising price regarding energy is not the best place to set up a mining farm except if you have a very specific deal with a energy provider or Dam privately owned etc.
Also you have to bare in mind some countries have pretty high fees on top of the elec price, such as Sweden where the grid fees are more expensive than the electricity price for instance.
Could you let us know what area in Europe you have in mind to set up your farm
