I'm a bit OCD-ish when it comes to symmetry. Guess I'm a stereotypical nerd in that regard
I'm a bit OCPD about correcting people using OCD when they mean OCPD.
OCD = Compulsion to repeat actions or avoid actions. IE, washing your hands exactly 20 times, never stepping on cracks, locking each lock exactly 3 times is OCD.
OCPD = A compulsion to set disorder into order. IE, alphabetizing the books in a bookstore when you don't work there or making sure all your steam pipes coming out of your boiler are symmetrical.
As for my power room, this is probably going to be the one that people look at and think, "That's it? That's like, the first day, right? Tell me that's the first day."
There's 3 generations of power in that picture. Hidden in the back are my original 2 TE Steam engines fed by hoppers. They are setup with an LP Supplier to keep them stocked with 64+16 scaffolds. To the side of it is an unimproved Forestry Electrical Engine which is hooked up to 5 standard solar panels. I have disabled Advanced Solar Panels, GregTech, etc, and only use base IC2, barely.
The 576 bucket, 3x3x4 railcraft biogas tank is fed by a single fermenter that eats saplings from a single spruce farm. It, in turn, feeds 3 biogas engines. That is my third generation of power. They replaced a set of TE Magmatics as I got sick of hitting up the nether for netherrack. All my 'rack now goes for obsidian.
The 576 3x3x4 tank is my fuel tank. It feeds into 3 BC combustion entines. That's the forth, and most recent, generation of power in my base. I've already blown them up once because I was feeding them using cobblestone waterproof pipes from the third railcraft 3x3x4 tank on the right. It is my water supply that feeds water to all my engines, a small BC tank next to my Thaumcraft crucible, and the carpenters in the foreground.
The whole setup uses TE REConduiets feeds into the bottom RECell near the Electrical Engine. That, in turn, feeds a Power Converters MJ->EU LV converter that feeds my whole 4, largely untouched IC2 machines. The fermenter has its own RECell so I can kickstart my fuel production as well as to throttle it to 1MJ/t. Of the upper RECells the right one is my portable power for far-off oil extraction. The left one is for my bank of TE machines, which is my primary ore processing setup. It throttles them to 30 MJ/t.
The biogas engines run 24/7 and provide a base 15MJ/t. This slowly trickle charges the primary RECell so that power is available when I hit peak demand. When I am running my ore processing or assembly table I turn on the combustion engines to provide another 18MJ/t to offset my peak usage. When I really overload the system I turn on the old Steam engines for an additional 8 MJ/t. The electrical engine kicks in another 2MJ/t during the day.
Base: 15MJ/t - 17MJ/t.
Peak: 33MJ/t - 35MJ/t.
Overload: 41MJ/t - 43MJ/t.
I'd say over 80% of the time I'm running at base generation and rely on the RECell buffers to accommodate any temporary usage over that amount. I just opened up the area behind the two tanks and intend to drop in another 3x3x4 and start producing biofuel. I'll probably moved my biogas production off saplings and onto cactus by then, too.
