One of my favourite books on renewable energy. A thorough account of every renewable energy form out there, is uses, its benefits and its draw backs. WEll reserached, well written, if anything a little too technical for me in some places but i am a relative newcomer to the subject. Everything is well illustrated and explained.
A very valuable resource to have on your desk. Besides being a bit technical for me in some cases, it is now a little old (2004 i think) and the renewable enery industry is changing all the time. If a new version came out i would buy it again. Immediately.
