Can someone please explain what a battery does?
I do not dispute that but what i was referring to was the distance plays a part in the distribution of power as well so if you have 3 lines connected to 1 node and farthest one has all your defenses then it would loss out to the other 2 nodes unless you stored some power during the round so that you had a reliable source when the wave came Generation is a key but distribution is the bottle neck unless you want to waste resources to build redundancies
if you have an energy overflow you can store the power in your batteries for later use. (for Example: you are using the water extractor to power the steam generator to generate power and you don´t have other generators, you have to power the extractor by the generator, but the generator needs water to give power now you use the power from the batteries) :) could be shorter but I hope u understand
