Query: A Good Place to Start your Energy Conservation Education

I've read the two volume Michael Reynolds "Earthship" Duo as a start to my new project to eventually design and build an energy independent and eco friendly retirement home. I'm not sure yet that I want a "composting toilet", but I do want to be educated about the entire process. This is the classic basic, The Earthship. It's a good way to start changing your mind set. How much hot water do I really need to be happy? Well organized and passionately written by someone who has dedicated a lot of thought to living responsibly on Mother Earth.
