I had the privilege of listening to Lord Brown (he of BP Fame). Here is his speech. Very interestingly, he does not sound like a typically demonised big oil head at all. He was very thoughtful, taking about the future, how we have to manage the energy usage and bring it under control. When a person like Lord Brown says that we have to have a good world to enjoy development when asked about the tradeoff between development and sustainable development/climate change, it makes one sit up and listen. Very interesting speech and would strongly suggest reading the whole lot.
