The issue of building wind turbines on the edge of Sheffield.

TASK 1:

What is the issue?                                                                        

In November 2003 it was announced that Sheffield city council were looking for sites on the edge of Sheffield for a wind farm. The site would be on the high moorland next to the Peak District where it is very windy. There would be 15 wind turbines. It is hoped that eventually Sheffield would produce all its own electricity and even have a surplus to sell. So should be a wind farm on the edge of Sheffield?

What is wind power?

Wind power is the result of using the wind to generate electricity. Today, a large wind turbine can power all the electricity needs of about 350 homes. There are many different methods of producing electricity, including burning coal and other fossil fuels. Yet most of these ways hurt the environment by polluting the air and water, and releasing dangerous gases into the Earth's atmosphere. Wind power does not have these effects, which is why we call it a clean, Earth-friendly energy source.

How does it produce electricity?

The electricity is produced using wind turbines .If the wind is blowing hard enough, starting at 7 mph, the blades of a wind turbine will spin. The blades are connected to a drive shaft located in the nacelle, or the box on the top of the tower. As the blades turn, the drive shaft turns and produces electricity. The electricity flows down the tower and into a transformer located outside the turbine. Inside the transformer, the electricity from the turbine is converted into electricity that we can use for power. The power flows to the project's substation and then into a large power grid. From here, the wind-generated electricity is sent through utility lines to its final destination.

Why is wind power important as a future energy source?

Electricity from the wind is clean, renewable, and inexhaustible. Nothing is burned or "used up" to produce wind power. Using wind power in place of coal, natural gas, or oil avoids the environmental impacts of mining, drilling, transporting and burning these fuels. Furthermore, wind power does not pollute the air or water, does not create hazardous waste, and does not produce carbon dioxide or other greenhouse gases. A single utility-scale wind turbine can prevent the emission of 5000 tons of carbon dioxide into the atmosphere each year. Which is very ...
