Unless it has internal tank and any adjacent generators burn it for energy. No pipes okay?
I know, IC² works with cells instead of using pipes.
In fact, to create Energy by Biofuel without wasting tin, we could have a sorts of machine wich would turn plantball into biofuel, slowly and with a little cost of EU (or without EU, but very, very slowly) and would be able to produce energy from this biofuel when placed near a Generator (as a compressor using water from pump without pipes/cells)
And in this case, we should too have same things for coalfuel:
Fuel would be made from Tar, wich can be finded lower than Coal and would be a bit rarer.
This Tar could be: Used in a reffinery, working with EU (I already post a thread containing a reffinery, but it was too speaking about Tier IV, so it was rejected, denied and put in the Archives) or used with sand/gravel to create Bitumen, allowing you to walk speeder on (something like Speed*1.25)
