Just some links from a lecture I went to this evening. The theme was a physicist’s view on renewable energy and there was a lot of counting Watts and Joules. Anyway, I’m no good at counting Watts and Joules so I’ll just supply some links highlighted by the speaker.
The website (link bonanza) set up for the lecture
A solar calculator to figure out the best place for that solar collector
A link to the online version of David JC MacKay’s book Without The Hot Air.
Last and most highly recommended by the speaker a series of 5 lectures by Amory Lovins from the Rocky Mountain Institute website.
