Passive Solar Design: Passive solar design can be integrated into traditional southwestern styles, or used in more contemporary designs that maximize solar efficiency to provide up to 90% of home heating demands. 

Off-the-Grid Systems describes the independent electrical power systems used in homes that are too far from existing utility power lines, or as backup for on-the-grid homes during utility power outages. Independent power systems may use a combination of solar photovoltaic panels, wind or small hydroelectric generators, which are combined with storage batteries, controllers, and inverters which convert the direct current of these devices to normal voltage (110v/220v) for conventional lights, appliances or tools.
