Oddly enough those that want electric/battery devices never explain where the energy comes from for: a)mfr batteries b)charging the batteries c)disposing of the batteries.
Likely because windmills don't supply enough energy to cover the cost of building/installing & maintaining them. Solar cells aren't efficient enough to provide the energy needed to cover their cost, replacement and they utilize aforementioned batteries for storage and use.
Nice ideas, but until technology catches up to the pie-in-the-sky wishes for clean energy it ain't happening.
