Australian government energy pricing audit...possibly show that solar and wind outstrip coal as cheapest source by 2030...? http://www.bree.gov.au/publications/aeta.html
Energy use per person
From Thomas L. Friedman's Hot, flat and crowded, p 104
2000 to 3000 kcal/day - energy required simply be alive i.e. what our biology needs.
230,000 kcal/day - energy consumption of the average American, i.e. each person is consuming about 100 x what their body actually needs to live.
Apparently people in other developed nations use about half that, those in India and China 9 to 30 times less.
His source is a 2007 InterAcademy Council report "Lighting the Way". This report looks like a good source of info on energy...in 2007 anyway.
