Alblaka, I have an idea for you. You should make a machine (I don't know what to call it) that when it's surrounded by leaves on the top and 4 sides, it produces 1 EU per tick, or 1/5 the amount that solar panels produce. When adjacent to the machine, the leaves have the same requirements as the solar panels do. Just an idea that I had, please reply back to me concerning whether or not it is possible/practical. If you completely dismiss it, I would understand, you probably have dozens of ideas that are way better!
Recipe:
=Leaves
=Sugar (a byproduct of photosynthesis IRL. Something inside me said it needed to be included in the recipe )
