I filled a Bedrockium Drum with oil, then used BC Refineries to fill a drum with Fuel. Then I made 16 Semi-Fluid Generators (32 EU/t each so that's 512 EU/t total) and finally just plugged em all in and ran the fuel line... OMG I had no idea they hum really loudly, now I have to re-think the entire design. Since there's power loss over distance in IC2, you really want to keep your power close to your row of production/processing machines. Ugh. After a month or two with Infinity modpack, I finally decided to work on the IC2 side of things. Now I remember why I put it off for so long.
Yeah, on the RF side, Big Reactors has easily become the greatest mod that just does its job quietly (QUIET IS GOOD!) and doesn't cause any fuss or bother. And I recently completed a twin Turbine project run off a little reactor in the middle which turned out quite well. BR is a "user-friendly" mod. IC2, not so much I guess. LOL Ah well, with the Magnum Torch I can pretty safely keep the master volume way down while I play.
But the tl;dr is, Oil/Fuel for EU and BigReactors for RF.
