In fact adam (see above comments) is the guy who started up energy bulletin. I've now added The Oil Drum and Robert Rapier to our list of other blogs. cheers, Iain. Hi Christian,

I’ve already added energy bulletin. In fact adam (see above comments) is the guy who started up energy bulletin. I’ve now added The Oil Drum and Robert Rapier to our list of other blogs.

cheers, Iain.

Have you seen any similar information on economic payback in Australia? The CSIRO report presents an excellent summary of the energy payback times.

Jeff Vail introduces these issues in an essay at The Oil Drum, you might be interested in: http://www.theoildrum.com/node/2892 Best, Adam hey Iain,
