David Mackay of The Royal Society (bastards) has produced an excellent guide to balancing State energy budgets.
It is online; http://www.withouthotair.com/; and printed as a Creative Common.
It includes The energy cost of “defence”; a rare and important attempt at a fully referenced quantification of military consumption. R&D spending in the military sector is 40 times that spent on renewable energy.
He welcomes new information for future editions. It would be interesting to see consumption plotted against class.
Leaving a pause after publishing this book, the devious ruling class bastard has revealed his true colours; he is a Nuclear lobbyist. The analysis in his book can be used to demonstrate that if society used less energy we could live with 100% renewables, but as a powerful government advisor, Mackay has now come out against these changes and in favour of Nuclear.
This was soon followed by the news that the government intend to leave Nuclear waste in landfills in working class areas, and not in Professor Mackay's garden.
