Most "green" homes are located far from city centers. In San Francisco, limited land availability and notorious red tape can make it especially hard to build with sustainable materials and renewable sources of energy. However, Robin Wilson's zero-net-energy home, in the heart of one of city's oldest neighborhoods, is lauded as one of the world's "greenest" residences.
Nicknamed La Casa Verde, this Mission District dwelling gets power from the sun and wind, and was built with a laundry list of eco-friendly materials. It's one of the first U.S. homes to achieve certification through Leadership in Energy and Environmental Design ratings.
