[abstract] Wind power is renewable and helps reduce greenhouse gas emission from the energy sector; however, it also has undesirable impacts on the environment. Studies from Europe and the USA report negative impact of wind farms on wildlife, especially on birds. India, the fourth largest producer of wind energy and also a mega biodiverse country has little information on this issue. Here, we report bird collisions from two wind farms: one at Kutch, Gujarat in western India and another from Davangere, Karnataka in southern India. A total of 47 bird carcasses belonging to at least 11 species in a period of three years were reported from Kutch and seven carcasses of at least three species in a period of one year were recorded at Davengere wind farm. The estimated annual bird mortality rate for Kutch was 0.478 birds/turbine and for Davengere it was 0.466 birds/turbine.

[abstract] Wind farms are a cleaner alternative to fossil fuels for mitigating the effects of climate change, but they also have complex ecological consequences. In the biodiversity hotspot of the Western Ghats in India, we find that wind farms reduce the abundance and activity of predatory birds (for example, Buteo, Butastur and Elanus species), which consequently increases the density of lizards, Sarada superba. The cascading effects of wind turbines on lizards include changes in behaviour, physiology and morphology that reflect a combination of predator release and density-dependent competition. By adding an effective trophic level to the top of food webs, we find that wind farms have emerging impacts that are greatly underestimated. There is thus a strong need for an ecosystem-wide view when aligning green-energy goals with environment protection.

Maharashtra shows that when incentives for wind energy are based on investment, not power generation, they give a fillip to moneymaking rather than clean energy.
Progressive Maharashtra has rushed to install wind energy plants. But, ask Nidhi Jamwal and Shikha Lakhanpal, reporting from Mumbai and Dhule, why so little electricity is actually generated. Is there another purpose to private interest in wind? Of greater note: If India must develop wind energy, should it go the way of this state?
