If you're as interested as I am about renewable energy then I suggest you read this article about an island in Denmark called Samsø. This island is completely self-sustainable since 1997. This is a truly unique island it gives hope to a change in the way we live. The studies that they are performing will hopefully help us to gain more knowledge and acceptance toward renewable energy in the United States. The article is called The Island Of Power.
You should also check out the sight that I found the picture on, they have even more great info about this island!
