You know the answers to these questions. Of course the turbines are not produced locally. Of course (in France) the local network cannot be independent of EDF.

Wiring towards consumers, maintenance, etc are done by the local network employees. Writing software or regulations at local level is not impossible, though obviously standardisation would be desirable.

But my point was not to say that there was no need for largescale industry. Just to counter the local=candlelight theme.
