Economies of Scale - Giant Wind Farms

This BBC article on the granting of permission for a giant wind farm off the coast of North Wales might be a good example of the importance of economies of scale in making renewable sources of energy more cost efficient. And heading to the web site of the Gwynt y Môr Offshore Wind Farm accesses some resources on the potential costs and benefits of a scheme that might provide electricity for up to 500,000 homes. If construction goes to plan, the wind farm will start to produce power from 2012.
