“Social Wind” is the wind generator system which helps local community to be self-sufficient and independent from energy. Once a local community raises fund and builds up a new wind turbine, it can get life-time free electricity generated by the wind turbine built. This system can be applied to encourage the coporate donation as well. A company can take part in as a insvester to build a new wind generator and get electricity back. Or a company can donate to build a turbine that helps needy community use free electricity.
