I made the following changes to power generation on my server, through decompiling the server jar and tweaking a few constants :
Solar produces HALF the energy output it did before. Solar NEEDs a nerf...it's stupid how OP it is.
Wind is halved as well, since with the nerf it's still twice as good as solar and it is renewable energy that requires no maintenance.
This makes Water Generators just as good as solar (they were half what solar was before). I made them work ONLY if there are flow blocks adjacent, still blocks no longer count. That nerfs them a little.
And finally, to compensate for the fact that nuclear reactors always sucked and were a waste of materials compared to tons of solar, and now you can no longer massfab for uranium so they are not even a renewable energy source, I made nuclear fuel last 4 times as long.
Also, I made recycling take 10 times as much energy. Recycling was the most OP and broken thing in all of industrialcraft 2.
