5 Savonius Vertical Axis Wind Turbines [20] The Savonius rotor sweeps an area in vicinity to the ground, resulting in less effective overall energy extraction due to lower wind speed at lower heights. Buhtta et al. [27] states that the Savonius rotor is one of the several configurations that are useful in generating wind power. The Savonius VAWT is often employed in instances where reliability matters more than efficiency. Such applications include deep water buoys, advertising signs designed to draw attention to a message, and in the case of most anemometers.

Renewable energy is an essential source for harnessing natural forces such as wind energy in an age which is very conscious of the environmental effects of burning fossil fuels, and where sustainability is an ethical norm. Therefore, the focus is currently on both the adequacy of long term energy supply, as well as the environmental implications of...
