Red, Golden Arches, and Green

MacDonald's sign in Cornwall, England, powered by solar and wind.
The sky was rather grey that day, but the wind was blowing nicely (it was raining, too!).
Pretty typical weather for Cornwall, and that wind generator was spinning like crazy!
There are so many illuminated signs in non-city areas where a panel and small turbine can be mounted near an illuminated sign or on the roof of the building.
So easy, so obvious, and a drop in the ocean for the budget of a major company.
Yet, if everyone did it, the effect would be HUGE!
Good on you McDonalds!
