[ANNOUNCER] High above London, the sails of a modern windmill feel for the breeze. Nearly 70 years after electricity was first generated for public supply, man turns once more to the wind for power. In these eight 6-volt car batteries, the power generated by the wind is stored. At 450 revolutions per minute, the current builds up. What does it mean to you? Just the gaiety of shop window lighting, despite the ban.

[ASSURAS] Today, the U.K. gets about 3% of its electricity from wind, according to the nation's Department of Energy and Climate Change. Now, to compare, the U.S. gets about 2% of its electricity from wind.
