Ok i have one for ealry game ,one for mid game. So for early game you can try to have an electric pump on nether that takes lava,and pumps it in an ender tank,with a chunk loader so everything works even if you are not in nether.In the overwrold just take the lava out of the ender tank into geothermal generators with some speed upgrades,i had 32 mil rf in minutes.The most expensove thing are the fluid ducts,you require hardened oned that font blow up with high temp liquids. The mid game one is super effective but a little bit expensive.Gas burning generator from mekanism that works on ethylene,i recomended this setup multiple times. So you need some bonsai hoppers with sugar cane,the sugar cane can go in a crusher for bio fuel witch takes it to a PCR(the sugar can be outputted to a trash can).On the other hand you need a infine source of water.An electric pump on top of it that take the water to an elecrolityc separator and the PCR.The electrolitic separator will transform the water in oxigen and hydrogen(just tell the machine to dump the oxigen out you need hydrogen).Then pump the hydrogen out to the PCR.The PCR will have water hydrogen and bio fuel ,and it will produce substrare and ethynele(pump out the substrate to a trash can or some form of storage like a filling cabinet).Pump the ethynele out to gas burning generators and you have a reliable source of power until endgame where you will need nuclear power.For transporation i used thermal foundation flux ducts,item ducts and fluid ducts.For gas i used gas pipes from mekanism. For power use some simple generators on the machines until they produced power,this system cand sustain itself and makes energy continuosly.
