We're discussing the new Saab, its not electric, its diesel so they are rewarding the low emissions. I agree the government can do more, but why criticise even a small step if its in the right direction. And as for your electric car statement, you're right its not as eco-friendly when you examine the supply chain, but thats not necessarily the main driver, its about reducing our need for oil. The government will be providing grants up to 5k when you buy (still expensive) electric cars.
Also, the government is looking internally as well but we would be the first to shout if they put us in even more debt by making wholesale changes. They are making low cost small changes - for instance they've just signed a new contact with HP charging HP with the challenge of reducing power/energy costs of IT.
