Recently I did a days work experience with Alternative Energy BP's alternative energy company. It was very interesting and I learnt lots - and got lots of freebees - including a 128MB USB flash drive.
I learn't for example that they think that the oil spike will be between 2015 and 2040 - depending on whether demand increases or decreases and on how much new supplies are discovered or made accessible.
I got some more idea of just how big the problem is - they think we would be lucky to stabilise CO2 production in 20 years rather than the suggested 10 to prevent catastrophic and uncontrolable warming. We have already caused a 3 degree rise - it has just not caught up with us yet - now we must decide whether we want the total to be four or six - bad or terrible.
