Introduction. The wind power is one of the indirect solar energy technologies. The wind is the air in motion resulting from the pressure gradient caused by solar radiation. About two per cent of the solar radiation reaching the earth''s surface is converted to kinetic energy and this is sufficient to meet the energy demands if it is harnessed.
