Great Piece. Richard Heinberg does great work and was a very early voice in Peak Oil. He was up front and center in a documentary that was also early in the game: "A Farm for the Future"- a nice introduction to permaculture, peak energy, and our growing crisis. (Curiously, the BBC now keeps that piece more guarded than it used to but I think you can still find it on YouTube) I assume your Utah winters have a quite a bit more light than the Northwest so a decent greenhouse and passive solar should work well. Have you considered using low grade geothermal like the designs featured in the man behind "Citrus in the Snow" (northern plains of Nebraska)? Its a genius design. Have you cultivated any perennial edibles? Eric Toensmeier has done some great work in that area as well.
