Hey! You forgot Bluetricity and UE power!
And there's already a What does YOUR power room look like thread on this forums.
With like 40 pages of people showing their power systems...
http://forum.feed-the-beast.com/threads/what-does-your-power-room-look-like.2129/What does your power source/room look like? I'm currently just trying to find a decent setup that can produce enough MJ/EU.
Instead of just telling the OP, show them the link. That way your post will be useful.

If anyone's posted their power room, it'll be here. I should look into getting this thread moved to "Community Showcase". The "Show us your base" thread is also useful since it shows entire bases, with power rooms included.
So you don't want new people to use the search option instead of opening new threads all the time to get a link to an already existing one? xD
I find that (using IC2) EU is much more easy to produce. And once you have a good setup you can just place a bunch of electrical engines.
After Clockwork, I'd say that MJ is easiest.
Force engine on milk runs 10 mj/t. Now say mj is hard to produce
WHAT? No one told me that! Time to get a cow farm
