Old Speckled Hen Posted March 5, 2009 Share Posted March 5, 2009 Sustainable Energy - Without the Hot Air Have a look at this wonderful book about the energy aspects of our global problems whether you call them global warming or whatever. You don't even have to buy it as it's available as a free pdf download from the author's site. I'm mid way through it and it's fascinating.
