So , the thing is, I love physics. I want you all to do the best that you can. I am, however a purist and a stickler for the rules. In all of the videos you see on this page you will here the narrator talk about electrical energy being the input. I know your smart enough to already know what I'm going to say, right?
Thats right, electrical energy isn't an energy store, its a pathway. So the more correct way of saying it wouls be something along the lines of...."the input energy comes from the chemical energy store via the electrical pathway". It could be kinetic energy from the wind transferred via the electrical pathway....you get my drift.
