Often overlooked and cited as difficult to harness,wind energy gets a bad rep owing to outdated misconceptions around the ways in which it is utilised. However,wind has slowly grown to become a major contributor to the total energy output of India.
As of 31st January 2017 the installed capacity of wind power was 28,871.59 MW, accounting for nearly 8.6% of India’s total installed power capacity.
By the end of 2015 India had already become the 4th largest in terms of Installed wind capacity all over the world, with new areas being identified regularly for tapping this form of solar energy. Wind energy also derives from the sun, as temperature gradient created by the Sun’s heat gives rise to air currents in the form of Wind.
Applying mathematical and mechanical optimisation methods to wind farming has lead to a significant rise in efficiency with which it was harnessed. Once the area is identified for a Wind Farm after selection on the basis of available wind data, CFD analysis may be applied to optimise its layout. Trading off between the various aspects according to location is critical to efficiency, and oftentimes larger blades (5 -9 times the rotor diameter) are used when there is a consistent flow.
We know these techniques and can optimise a wind farm to its maximum output, which equals free energy in a short time.
