The Indian wind power segement recorded its highest ever capacity addition in 2010-11. A total of 2,350 MW capacity was added during the year (accounting for about 16 per cent of the total capacity addition in the power sector and 74 per cent in the renewable segment) compared to the average capacity addition of slightly over 1,570 MW in the period between 2007-08 and 2009-10.

Despite facing infrastructural bottlenecks, SHPs (small hydroelectric power) stand second only to wind power in terms of contribution to renewable energy in India and hold immense potential for makers to cash in on the growth. All that it needs is the right policy push.

Wind energy, if improperly sited, can impact wildlife through direct mortality and habitat loss and fragmentation, in contrast to its environmental benefits in the areas of greenhouse gas, air quality, and water quality. Fortunately, risks to wildlife from wind energy may be alleviated through proper siting and mitigation offsets.

This paper deals with two methods of obtaining 50Hz sinusoidal voltage waveform of constant amplitude same as the amplitude of grid voltage from a variable amplitude variable frequency sinusoidal voltage waveform so that a variable speed wind turbine generator can be joined to grid.

Wind power plants are most productive when nothing blocks their access to the wind. But turbines often take wind away from each other. Repowering and the allocation of new priority sites are aggravating the problems the most.
