Many people assume that renewable energy systems are out of their price range and technologically complex. That doesn’t have to be the case. This new week-long course will present several low cost, low tech options for introducing renewable energy systems and ecological design strategies into your home. Class lectures will cover a variety of systems, including hydroelectricity, wind power, biodigesters, solar hot water, water filtration units, high efficiency stoves, and small-scale foundries. In addition, students will gain hands-on experience with three renewable energy systems: using ram pumps to move water, building a basic greenhouse for add-on passive solar home heating, and creating a biodiesel reactor to produce energy from waste vegetable oil for home heating and vehicle use. The instructors will also discuss the application of these technologies in a developing country context. All Levels.
