Yes, i'd love to see more uses for power. I generally play on servers, and it seems to be just bragging rights for how much power you can generate. Along with how much unused metals and diamonds you have in an ME system. Or cobble, or saplings, etc.
It doesn't take long to get enough power in any mod, and then nothing much to use it on. At least some mods are becoming more and more configurable. I notice power from Big Reactors is much lower, and recipes a bit tougher, in TPPI2 than in Infinity or DW20, which i sort of like. As is, there's something wrong being able to jump to nuclear power with only a furnace and crafting table.
