Italian town makes profit selling excess wind power

The Italian town of Tocco Da Casauria is being held up as an example of what is possible with renewable energy.

Wind powers the entire town of nearly 3,000 people and the turbines produce much more than Tocco needs.

The excess is sold back to Italy's national grid and the profits are pumped back into local services.

Town mayor Riziero Zaccagnini explains what makes Tocco so special and the lessons that can be shared with the rest of the world.
