Selected coastal areas of Pakistan (Karachi, Ormara, Jivani and Pasni) were studied for the possibility of wind energy generation, using available meteorological data. Wind speed pattern, Extractable Wind power, Wind Energy and associated Weibull parameter for these coastal areas have been examined. The analysis also includes seasonal changes in wind speed values. The power output using fast and slow wind machines using dierent blade diameters have been estimated to explore the possible use for irrigation deep well pumping and small scale power generation. Along with this, 4 KW and 20 KW aero generators were also examined. It was found that, considering maximum location wind speed, Pasni is the best location; and Jivani is the next best location with stable wind throughout the year. The other two locations were found to have similar same properties.
Key Words: Assessment, Coastal areas, Wind power potential, Weibull Distribution.
There is rising need for alternate and renewable sources of energy, especially in developing countries, whose progress and economic growth may strongly be indexed to its development. With the ever increasing growth in energy consumption and rapidly depleting fossil fuel reserves, it is feared the world will soon exhaust its fossil fuel reserves.
Pakistan is an energy decient country and each year spends a large amount of its foreign exchange to import oil, to meet its energy requirements.
Thus the need to develop alternate energy resources has become inevitable. The oldest and most widely used renewable energy resources are solar and wind, which have shown prospects and potential for ecient utilization. In the recent past, wind energy has emerged as clean, abundant, aordable, inexhaustible and environmentally benign source of energy. This is getting worldwide attention with the development and availability of inexpensive technology that allow its easy conversion into useful energy.
Wind energy has the advantage that it can be utilized independently, and deployed locally in rural and
remote areas. Thus the location far away from the main grid nds wind suitable for generating electricity and
pumping water for irrigation purpose.
