Wind energy is renewable & posses no major environmental problems. Wind energy potential for different applications cannot be overlooked in a country like India where considerable amount of wind power is available. There is growing international consensus on the challenges in the energy sector from the high cost of oil & long term energy security, to environmental concerns & commitments like Kyoto protocol. Many countries are trying to adopt policies to encourage investment in wind energy and the development of the industry.
There is no fundamental reason why wind turbines cannot be a major part of any utility grid where there are good wind resources, provided they can complete with more familiar systems on the basis of cost , reliability & public acceptance. In this context , wind energy has found a very conducive environment to build synergies in operations around the world. Although wind energy technology demands careful attention to scientific & engineering detail, it is well within the capabilities of most if not all countries & is becoming economically competitive is many regions around the world. In parallel Indian industry has gone through a resurgence of entrepreneurship & emerged with a will to take on the world.
A country wide wind pump demonstration program is being undertaken in India & over 2000 wind pumps have already been executed. It has been verified that the average capital cost & cost of power generation for 1Mw projects undertaken is India so far , ranging between Rs 1.5 to 1.75 crores/Mw & Rs 1.25 to 1.5 Kwh respectively, depending upon the site. These costs are already comparable to those for thermal power generation & lower than generation of power from thermal units. Exactly capitalizing on this Suzlon energy limited ,just over a decade worked to harness the wind across India & became the world largest wind turbine manufacturer in terms of market capitalization.
However due to the diminishing supplies of conventional fuels , cost for thermal power generation has been considerably increasing which made wind energy to play an increasingly important role in world full of booming economics, to power the world with bright future.
