WIND ENERGYMade By:Hayyan NiamatullahAhmed NavedMohammed Huzaifa S . Junaid Humail

Introduction

Humans use wind power , or motion energy , for many purposes : Sailing, Flying a kite, and even generating

electricity. In the recent past, wind energy has emerged as a clean, affordable, inexhaustible and an environment-

friendly source of energy. This presentation will tell us all about the wind power/energy and where they are found in

Pakistan

Current locations in PakistanJhimpir Project :-

The Jhimpir Wind Power Plant is the first wind power plant in Pakistan. The wind farm is being developed in Jhimpir, by Zorlu Energy Pakistan the local subsidiary of a Turkish company. The total cost of project is $136 million. Completed in 2002, it has a total capacity of 50MW.

Wind Power

Feasibility of developing wind power source

Pakistan is fortunate to have something many other countries do not, which are high wind speeds near major centres. Near Islamabad, the wind speed is anywhere from 6.2 to 7.4 metres per second (between 13.8 and 16.5 miles per hour). Near Karachi, the range is between 6.2 and 6.9 (between 13.8 and 15.4 miles per hour). Pakistan is also fortunate that in neighboring India, the company Suzlon manufactures wind turbines, thus decreasing transportation costs. Its turbines start to turn at a speed of 3 metres per second. Vestas, which is one of the world’s largest wind turbine manufacturers, has wind turbines that start turning at a speed of 4 metres per second. In addition to Karachi and Islamabad, there are other areas in Pakistan that receive a significant amount of wind.

In only the Balochistan and Sindh provinces, sufficient wind exists to power every coastal village in the country. There also exists a corridor between Gharo and Keti Bandar that alone could produce between 40,000 and 50,000 megawatts of electricity.

Given this surplus potential, Pakistan has much to offer Asia with regards to wind energy. In recent years, the government has completed several projects to demonstrate that wind energy is viable in the country. In Mirpur Sakro, 85 micro turbines have been installed to power 356 homes. In Kund Malir, 40 turbines have been installed, which power 111 homes. The Alternative Energy Development Board (AEDB) has also acquired 18,000 acres for the installation of more wind turbines.

In addition to high wind speeds near major centres as well as the Gharo and Keti Bandar corridor, Pakistan is also very fortunate to have many rivers and lakes. Wind turbines that are situated in or near water enjoy an uninterrupted flow of wind, which virtually guarantees that power will be available all the time.

Advantages of Wind Energy1. The wind is free and with modern technology it can be captured efficiently.

2. Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants.

3. Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue.

4. Many people find wind farms an interesting feature of the landscape.

5. Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply.

6. Wind turbines have a role to play in both the developed and third world.

7. Wind turbines are available in a range of sizes which means a vast range of people and businesses can use them. Single households to small towns and villages can make good use of range of wind turbines available today.

 

Disadvantages of Wind Energy

1. The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all.

2. Many people feel that the countryside should be left untouched, without these large structures being built. The landscape should left in its natural form for everyone to enjoy.

3. Wind turbines are noisy. Each one can generate the same level of noise as a family car travelling at 70 mph.

4. Many people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They disfigure the countryside and are generally ugly.

5. When wind turbines are being manufactured some pollution is produced. Therefore wind power does produce some pollution.

6. Large wind farms are needed to provide entire communities with enough electricity. For example, the largest single turbine available today can only provide enough electricity for 475 homes, when running at full capacity. How many would be needed for a town of 100 000 people?

Wind Power Proposed Projects

Pakistan is developing wind power plants in Gharo, Keti Bandar and Bin Qasim in Sindh. The government of Pakistan decided to develop wind power energy sources due to problems supplying energy to the southern coastal regions of Sindh and Baluchistan, the project was undertaken with assistance from the government of China.
