Considering to increase the EU-cost for UUM, btw
Excellent Idea. I feel the same way, UUM is far too easy to get with weak arrays of solar panels. If you added a T4 generator it would make since to increase the cost of UUM greatly.
On my server, since we have RP2 and can make CASUCs pretty easily, we effectively have T4 generators. (a bucket fed reactor that outputs 1700 EU/tick is better than the official T4 you are probably going to add). I'm considering doing 2 things : increasing the EU cost of UUM five times to 5 million EU base energy (and increasing the cost to run a recycler to 15 EU/tick) and making nuclear fuel last 5 times longer in a reactor.
With the changes, a player who does fuel breeding perfectly (which is much easier to do with 5x longer fuel life) will get enough energy from 1 piece of uranium, including the cost of the coal and tin, to make 150 pieces of UUM. So it wouldn't become impossible to get UUM, however it would be very very difficult to get significant amounts of it from anything but nuclear energy, which makes sense to me.
