Selected Environmental Impact Indicators Assessment of Wind Energy in India Using a Life Cycle Assessment

This study focuses on the life cycle assessment (LCA) of an onshore wind farm in India. The is conducted 10 Vestas 1.65 MW turbines situated Karnataka state Following ISO 14044 standard, SimaPro LCA software used to model process. functional unit chosen as 1 MWh sent out electricity. results cycle-based emissions are compared with those coal power plant. global warming potential found be 11.3 g CO2-eq/MWh for power, which 98.8% lower than that A comparison data available was carried GaBi software. There a small difference between two databases. may due different boundary and inclusion input items. Steel, aluminium, concrete contributed 86%, 84%, 84% 85% total CO2, NOx, SO2 PM2.5 emissions, respectively. Recycling materials turbine at end its can reduce environmental impact. Higher capacity factors increase electricity generation reduced 22% factor impact by 19%. In addition, reduces impact, only has few moving parts requires minimum regular maintenance.
