I saw this video about a year ago now, if not longer, but in light of the UN Climate Change Conference taking place in Copenhagen, I thought I'd post this video for your perusal. On Youtube it's entitled 'The Most Terrifying Video You'll Ever See', and if you're in any way concerned about the future of this planet then I'm inclined to agree:
In a similar vein, Oggs and I watched 'Bang Goes the Theory, Human Power Station' on the BBC last Thursday. In brief, the experiment involved a family of four in a house being unhooked from the mains, and instead powered solely by pedal power. In a warehouse next door there was an army of cyclists ready to supply all their electricity needs using dynamo's attached to the back wheels of their bikes. It was essentially an example of just how much energy the average family uses (and wastes) day to day, painfully illustrated by the blood sweat and tears being shed by these poor cyclists.
If you didn't catch it then I urge you to check it out on iPlayer...I've certainly been turning more lights off.
