The document discusses ecological buildings and renewable energy sources for powering a home without electricity. It poses one big question: How could you power your house without using electrical energy sources? And three smaller questions: How can the design affect this? How do you heat the hot water? How do you supply energy/power to your appliances? Potential renewable energy sources discussed include wind mills, solar panels, hydro dams, and backup biodiesel generators.
