Hey,
I've wanted to get energy with a water mill. But it wont work. I made some screenshots, because i can't find a fail in my building.
Screenshots are in the Spoiler.
The machine in the middle should get the energy.
Here are the cables from the water mill to the machine
And thats my construction...
I also tried to produce energy by put water buckets in the water mill. But it will not work, too.
I hope, that someone can help me.

Looks like your cable is too long.
EDIT: With water buckets, 1 EU/t should reach the machine.
I will test it again with a short cable
Edit: But the water bucket in the water mill will not dissapear 
Ah ok... You are right. The cable was to short and the produced energy is too low. It's like... blinking all the time. Thank you 
Use tin cable going from the watermills to a batbox, then copper from the batbox to machines. Try to limit lengths of copper cabling to 4.
Here is a useful tool.
Cable loss calculator.
