The U.S. led the charge with a record-breaking 5,244-megawatt increase for a total of 16,818 megawatts—enough to power 4.5 million U.S. homes.
how does wind power work?
i know that
the turbine blades capture wind energy and start moving,
they spin a shaft that leads from the hub of the rotor to a generator
The generator turns that rotational energy into electricity.
but how does the generator turn the rotational energy into electricity?
please include a reference if you can.
thanks
Swedish energy giant Vattenfall says the 100 turbines should provide wenough electricity for up to 240000 homes.

The National Energy Board said Monday it broadened the scope of its Arctic offshore drilling review to reflect public input in the multi-phase process. The board’s review will address environmentally safe drilling practices, effective emergency responses, lessons learned from the Gulf of Mexico deepwater drilling disaster and filing requirements for companies.
