Since I had a long break from minecraft, I've found some amazing mods like buildcraft, computercraft, forestcraft where you can build machines, robots, refineries etc
Oil (black) is being pumped into containers and then into refinery that's powered by engines. That configuration isn't effective, but for start ok and produces fuel to power most powerful combustion engines.
Old quarry in background and solar panes in front, produce electricity to power supply...
...electric macerator, compressor, cannery machine, extractor, electric and combustion furnaces. Those are useful to produce many resources (most of them is brand new in game).
And it's only a very small part of those addons.
