Britain peak power demand (from BBC TV series: Britain from Above)

I was blown away by this clip from the show called "Britain from Above". I recommend you catch it on a BBC channel near you.

An epic journey revealing the secrets, patterns and hidden rhythms of our lives from a striking new perspective.

Join host Andrew Marr as he discovers how each and every one of us is interconnecting making Britain what it is today.

Britain looks very different from the skies. From a bird's eye view of the nation, its workings, cities, landscapes and peoples are revealed and re-discovered in new and extraordinary ways.

Cutting edge technology allows you to see through cloud cover, navigate the landscape and witness familiar sights as never seen before.

This landmark series of documentaries was filmed in High Definition and aired on BBC One, Two and Four for three weeks starting August 10, 2008. See On TV for details of repeat broadcasts.
