Estimation of Power Rating of a Horizontal Axis Propeller Type Turbine

Energy is a driving force for life on the earth. Much of the energy which is available on the Earth originates from the Sun. This also includes renewable sources of electricity generation such as solar, wind& wave energy, and hydropower (since weather patterns are driven, to a significant extent, by the energy input from the Sun). However one potential for electricity generation from is the wind energy as result of the uneven heating of the earth. About 1 % to 3 % of the solar energy falling on the earth surface gets converted into the wind energy. The solar energy to the energy conversion is about 50 to 100 times higher than the solar energy to biomass energy through photosynthesis. Presently in India there energy production through wind energy is estimated about 45000 MW. Currently we are exploring only 9000 MW (25 %). All over the world, the annual wind market is growing with over 30 % rate.
