This post was originally written by me as a guest post for Rob Hopkins’ Transition Culture blog, but I have kindly given myself permission to reproduce it here 😉
So here I am. I fully intended to be giving the England match my full attention right now, but I’ve been left distinctly restive by this afternoon’s long session by Stoneleigh of The Automatic Earth, and feel the need to put some thoughts down.
Including the extensive Q&A session her talk lasted virtually three hours and covered a lot of ground, starting from a good runthrough of the ‘peak energy’ situation, but quickly focusing in on finance, as she believes that this is the factor that will most dramatically shape our immediate future. Notably, the talk attracted almost half the attendees of the Transition Conference, despite the numerous other Open Space sessions taking place at the same time.

As I mentioned in my earlier post, last week I met Polly Higgins, The Lazy Environmentalist. She specialises in CSP, and informed me that we may now be seeing serious political movement towards an EU-MENA supergrid bringing CSP-generated electricity to Europe from the deserts of North Africa and the Middle East.
For those not familiar with the concept, CSP is not about photovoltaic solar panels, but rather the simple use of mirrors to focus solar heat on pipes filled with water. This generates steam which turns turbines to generate electricity. It is a simple low-tech concept that has been operating a 165 MW power plant in California for over 20 years.
It has been calculated that, if it was covered with CSP plants, an area of hot desert of about 254 km x 254 km — less than 1% of the total area of such deserts — would produce as much electricity as is currently consumed by the whole world.
An area measuring 110 km x 110 km, a small fraction of the area of desert in North Africa and the Middle East, would produce the same amount of electricity as the European Union consumed in 2004. This is illustrated graphically below the cut.
So this political movement towards a CSP supergrid is a very significant development, and, I think, a positive one. Read more »
