As of low energy fuel consumption i mean directly pumping BC energy from BC engines to your Petrochemical Generator which is more fancy method then making a lava in eg. Thermal Expansion's Magma Crucible and then burning it in Geothermal Generator. But balance should be preserved in 2 conditions : 1. setting up low EU rate from default 16EU to 5 EU/t. 2. setting geothermal generator also to 5 EU/t from 20 EU/t.
Electrical engines will be great then after reducing amount of EU need from 8 to 4 per 1 BC. It will be nice inneficency coz of second law of thermodynamics :), but electrical engines should be used in non constant working situations in my opinion unless we have too much uranium or other crazy stuff from GregTech. We have so much BC liquid fuels now , (Plugins for Forestry), and i think that with that rates Petrochemical Generator is solution to transfer all that crazy liquids energy to EU. And better option is making from lava something worthy instead of making energy like TE liquiducts, copper, eletrum, tin from GT industrial centrifuge so nerf lava
Only pain is biofuel which is entangled to fuel
Sry for my bad english again .
oh, i have tweaked forestry config again in sugar canes consumption and fermener ate 34 canes now and burn 23 000 MJ for one biomass can (50000 MJ ) so its much better now with net 27000 MJ I think that config doesnt like too small values, changed from 10 to 30 and ate 34 canes now. Problem Solved
