I am no longer dependent on foreign oil! Now, I'm dependent on foreign lava. But, that's better, all I have to do is keep a steady supply of lava buckets coming in, and the geothermal generators automagically get stuffed. It's much easier to just go to the nether than to run to a bunch of distant refineries.
So as long as I have a stock of empty cells, I can easily manage. I have a huge stock pile of coal if things get hairy, plus 2 out of 3 6 block high tanks are still full of fuel, so I can run the 10 combustion generators in an emergency if needed.
I only need to turn those on when I need to use the assembly table.
Now, just an awful lot of cables to neaten up, and some serious channel management.
