Instructables
Wind power is a favorite for makers and amateurs interested in renewable energy, chiefly because the technology involved is simple and accessible. While solar, hydroelectric, tidal and biogas are difficult to achieve on a small scale and small budget, wind power has simple requirements that put it within reach of many hobbyists.

The only real requirement is an electric generator and some way to make it turn. These Instructables cover a range of wind power designs, from the traditional turbine-on-a-mast to more unusual vertically rotating generators, that are mostly constructed using simple and easily available tools and materials.
