Autodesk have (or are) sponsoring a very informative series of podcasts, the (e2 the Economies of being Environmentally Conscious), on environmental issues. there are 6 podcasts:

Chapter 1: Paving the Way
Chapter 2: Energy for a Developing World
Chapter 3: Harvesting the Wind
Chapter 4: Growing Energy
Chapter 5: State of Resolve
Chapter 6: Coal & Nuclear: Problem or Solution?

Interesting to note that the series is also being broadcast across the US on the PBS (Public Broadcasting Service). I am now wondering when we will see info-ads on climate change here in the UK, and hoping they are as informative and ‘neutral’ as this e2 series.
