The Cambridge Centre for Climate Change Mitigation Research published some interesting research last week. The Centre predicts that half the carbon emissions savings made from greater fuel efficiencies will be wasted by a corresponding rise in fossil fuel use.
Terry Barker, the Centre’s Director, says that the politicians have not considered what he called ‘the rebound effect’. “The rebound effect is not very welcome to politicians because they have been thinking that energy-efficiency programmes are the answer to climate change”. He continues:” it’s not nearly as good an answer as they thought. Efficiency programmes will have to be ramped up to achieve the same targets”.

Motorcycle racing isn’t usually associated with the fight against global warming. But on 12th June 2009, the world-famous Isle of Man TT races will include the TTXGP – the first ever zero-emissions grand prix races. All the bikes taking part will be electric.
Whilst they might be good for the environment, these bikes aren’t slow. They’re capable of up to 150 mph around the 37.733-mile TT mountain course. They have no gears, just different power settings. If the torque of Tesla electric cars are anything to go by, the acceleration should be phenomenal.

Surprisingly, the Tibetan village of Sher has existed for over a thousand years. Surprisingly, because Sher is perched on a small, dry plateau surrounded by mountains. The average rainfall is a mere three inches. And the annual temperature is zero degrees centigrade.
But the villagers of Sher use the resources they do have as efficiently as possible. A complex irrigation system makes the best use of the meagre rainfall. They use the highly-thermal wool from their sheep to make warm clothes and blankets.
