A different option, is to use the TE compression dynamo with ethanol.  Take saplings from your tree farm, run them through a fermenter to get the green biomass, put the biomass in a still to get the orange ethanol.  Feed that into compression dynamo. 
Take apples from your tree farm, put them in a squeezer, use the juice in a second fermenter to make even more biomass from the same saplings. Take the mulch from the squeezer and put it into both fermenters.

		 I keep forgetting about those irritating whores.  Though, I don't typically use mob farms for anything (they tend to lag), I wonder how much power one could get off witches in a MFR farm.  Also, is there any way to use their potion drops for power?  If not, there should be, damn it!
