TED talk on energy

A few weeks back Martin and I watched this TED talk entitled 'People, Power and Area'.  It's by one of my heroes - British physicist David Mackay who not only wrote the program I use to type using only a mouse but also wrote the wonderfully informative book Sustainable Energy Without the Hot Air.  I appreciated his clear explanation of why we can't just switch to renewable energy and otherwise carry on living 'business as usual'.  I was also stunned to learn that the UK and Saudi Arabia both had the same amount of fossil fuels under their soils (one in coal, the other in oil) before extraction started.  I hope to be able to direct people to this talk in future as a good, clear explanation of where the world is at in terms of energy availability.  To be honest, I do find a clear explanation of where we're at kind of scary, and it drove me to pray - thanking God that He is in control and pleading for his mercy in this dire situation.
