Don't just take my word for it.

"Green politics matter now more than ever. It is not woolly to be green at this time. It has never been more hard-headed. The crisis over the oil price is just one of many indicators that it is even more imperative to wean ourselves off fossil fuels and make the radical moves necessary to become a low-carbon economy. The fortunate countries of the future will be those with political and business leaders with the foresight to plan for that world by encouraging investment in clean and renewable energies, carbon capture and green transport."

I do disagree with the statement before that, though. But I recommend you read the whole article. Right through to the last perfect paragraph.
