Performance Analysis of Wind Turbine and it’s Economic Aspects

Wind energy, commonly recognized to be a clean and environmentally friendly renewable energy resource that can reduce our dependency on fossil fuels, has developed rapidly in recent years. Its mature technology and comparatively low cost make it promising as an important primary energy source in the future. However, there are potential environmental impacts due to the installation and operation of the wind turbines that cannot be ignored. This paper aims to provide resource use and emissions generated throughout the life-cycle of wind energy systems can be quantified, in a systematic way, by using the tool Life-Cycle Assessment (LCA). The present paper outlines the status of current LCA studies of wind energy systems. Further, it presents preliminary results from ongoing work on input-output modeling of wind power development. Implications of wind power going offshore, in terms of effects on resource use and emissions, are discussed, and opportunities for improving the environmental performance of offshore wind energy systems are identified.
