Ok this might be something harsh to say and people might get upset at me. But I for one would want to play on a server that people are smart. Maybe just a few generators. Like 15 or 20 really good ones. Not a crap ton of 50 or 100 maybe more. Some people don't think of the use on the server that many would have and if more than 1 person is using that many, than no wonder the server tends to lag and crash... And Nolan I've added my power output to your Tesseract channel.
I think there needs to be a better (larger) energy storage system along the lines of the enderio system. I have not played around with mekanism, but I know stacking lots of TE energy cubes would be a bad idea, as power would have to flow one by one through the chain, or there would be loops, causing more CPU usage. I liked the enderio system of making a multiblock energy storage system(although enderio's implementation in other areas was lacking). With Big reactors it is way more efficient to produce massive amounts of energy at once. The code itself gives bonuses based on reactor size and shape, bigger and taller (less pancake like) are better. I can either produce about 3k RF/t or 11k RF/t (or almost twice as much if I had a turbine capable of taking all the steam) on the same fuel just by reactor size. Without a way to store massive amounts of energy I will either be turning my reactor on and off constantly, or running a smaller reactor and wasting large amounts of fuel. This also can be applied with rotarycraft's gas turbine, which puts out about as my reactor does now. Having a truly humongous (even is extremely expensive) single block(or multiblock, but single entity) energy storage system could help a bit with reducing CPU usage, as power generation systems would be off 95% of the time, and there would be only a single device powering the entire base, only needing to calculate what energy is going out and what is left in the storage.
How do you figure for loops? The way that Redstone Conduits shuttle energy around kind of encourages more than one block, so that they can output/input at greater than their stated "capacity". Last round I had like 2bn in RF storage via a bunch of Resonant Cells. The cells input and output conduit networks were entirely isolated, no loops.
