One of my favourite publications is the annual BP Statistical Review of World Energy, the 2009 edition of which has just been published. I do not read it in bed - that would be sad - but make extensive use of it in my work.
The annual BP Statistical Review of World Energy is an essential reference source. It gives production and consumption statistics for many countries and all the regions in the world, disaggregated by oil, gas, coal, nuclear energy and hydroelectricity.
