I have a suspicious feeling that I might not be the first one to link to this video, or to any video I ever link to... But, anyways, here it is:
"Documentarian and journalist Nick Rosen discussed living off-the-grid, typically in alternative communities. This means living independently of the utility companies, and providing your own power, "but it does not mean living in the Stone Age," he explained. "It's about being more self reliant, being less dependent on the system, and realizing we have to look after ourselves," he added. Rosen bought a hut and some land in Spain along the Mediterranean and was able to go off-the-grid using such things as solar panels and rainwater harvesting. His website offers an interactive section called Landbuddy for people to help each other go off-grid in their local regions." - From Description
I found this interview extremely interesting. There are bits of useful names and ideas throughout the talk. It's generally about the USA, though.
