I love this article, the concept of permaculture. You've given me a new tag to follow. Your minute attention to consequences at every step is refreshing. I notice, when proponents of different energy sources compare consequences, they limit those to direct result of use. They rarely speak about the exploitation of resources, including natural and human, that go into mining, or creating, the energy. One question that may be stupid: is forage planted specifically for hay production and if so, what is it? Great post. I've shared it on Twitter.
