The most significant environmental advantage of wind energy is that it does not load the atmosphere with toxic chemicals. In contrast, the conventional power plants operating on fossil fuels release gases like sulphur dioxide, carbon dioxide and oxides of nitrogen during the energy conversion process. Similarly, particulates and toxic heavy metals which affect the environment adversely are also being generated during this process.
