"Not a source"?[edit source]
I find this confusing:
Electricity is a way to transmit and store energy. It is not a source of energy itself.
Wikipedia:Electricity says this (probably too vague, if not actually inaccurate): Electricity's extraordinary versatility as a source of energy means it can be put to an almost limitless set of applications...
My understanding was that electricity is a form of energy. Since energy is conserved, the source is also always a form of energy - e.g. the kinetic energy of water, or chemical potential energy of a fuel. --Chriswaterguy 08:58, 22 October 2011 (PDT)
