Wind Energy Development in India and a Methodology for Evaluating Performance of Wind Farm Clusters

Abstract

With maturity of advanced technologies and urgent requirement for maintaining a healthy environment with reasonable price, India is moving towards a trend of generating electricity from renewable resources. Wind energy production, with its relatively safer and positive environmental characteristics, has evolved from a marginal activity into a multibillion dollar industry today. Wind energy power plants, also known as wind farms, comprise multiple wind turbines. Though there are several wind-mill clusters producing energy in different geographical locations across the world, evaluating their performance is a complex task and is an important focus for stakeholders. In this work an attempt is made to estimate the performance of wind clusters employing a multicriteria approach. Multiple factors that affect wind farm operations are analyzed by taking experts opinions, and a performance ranking of the wind farms is generated. The weights of the selection criteria are determined by pairwise comparison matrices of the Analytic Hierarchy Process (AHP). The proposed methodology evaluates wind farm performance based on technical, economic, environmental, and sociological indicators. Both qualitative and quantitative parameters were considered. Empirical data were collected through questionnaire from the selected wind farms of Belagavi district in the Indian State of Karnataka. This proposed methodology is a useful tool for cluster analysis.

Generating Electricity Using Geothermal Energy in Iran

“…At present, oil exports account for 80% of total exports which accounts for nearly 50 percent of the government's budget and is 23 percent of the gross domestic product. With growing demand for energy, increased environmental pollution, and depleting energy sources, human society today faces multiple challenges of transition towards sustainable development and poverty eradication [20] .In 2005, 2713.4 million tons of carbon dioxide emissions from burning of combustible fuels have been released in the world. The 1671.7 million tons equivalent to greenhouse gas (CO2) emissions in the Middle East region have been released and 1,238.1 million tons of this gas were due to the burning of combustible fuels [21].…”
