The Parliamentary Standing Committee on Energy urged the Ministry of New and Renewable Energy to expedite the approval and implementation of the revised policy on repowering old wind turbines. In a report on the evaluation of wind energy in India, presented to the Lok Sabha recently, the Committee said most of the wind energy potential is concentrated in eight states and suggested retiring old, inefficient wind turbines occupying prime wind sites. It recommended replacing the old turbines with advanced, more efficient ones to maximize natural resources and land usage.
