Hybrid Streetlight Powered By Both Wind and Sun
In Canada, a company called Hybridyne Power Systems has created a streetlight that is powered both by the sun and the wind. An equivalent streetlight costs about $125 per year to operate. The system, called the "Kazekamome Remote Hybrid", features a solar panel on top, and a vertical-axis wind turbine positioned between the lamp's two poles. Since it is self-powered, it can be installed anywhere without expensive trenching and wiring. See this story about a recent installation, or click the link here to see another photo of the light.
