Modern wind machines which produce electricity are called turbines.They are connected to generators. The turning of the generator produces electricity and many isolated communities all over the world already have all their power needs met by wind power. They are linked to a power supply network, from which they are paid for the electricity fed into the network on windy days, and can take the power they need from the network on calm days. Co-incidentally, the strongest winds are in the winter when most power is required.
