Describe the bug

I was testing 0 energy usage and capacity on all blocks (as I recall there may be some cases where useEnergy is not respected/available on some) and found that setting useEnergy = false and capacity = 0 in the controller section causes the controller itself to not light up (it still works by activating connected storage blocks).
Giving it a capacity of 1 works around this allowing it to light up properly, but I thought I'd report the odd behaviour anyway!

Relevant log output

No response

Yes, that is normal. useEnergy stops the consumption of energy. If you change the capacity to 0, the network has no energy to use in the first place since there is no capacity for anything.

For this reason we're removing useEnergy in RS 2, it's confusing.
