1. Wind Energy

2. How it Works This view of a wind power plant shows how a group of wind turbines can make electricity for the utility grid. The electricity is sent through transmission and distribution lines to homes, businesses, schools, and so on.

3. How it Works Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity. Wind is a form of solar energy.

4. A specific place Since early recorded history, people have been harnessing the energy of the wind. Wind energy propelled boats along the Nile River as early as 5000 B.C. By 200 B.C., simple windmills in China were pumping water, while vertical-axis windmills with woven reed sails were grinding grain in Persia and the Middle East.

5. A specific place However, industrialization also sparked the development of larger windmills to generate electricity. Commonly called wind turbines, these machines appeared in Denmark as early as 1890. In the 1940s the largest wind turbine of the time began operating on a Vermont hilltop known as Grandpa's Knob. This turbine, rated at 1.25 megawatts in winds of about 30 mph, fed electric power to the local utility network for several months during World War II.

6. Advantages of using your alternative Wind farms are relatively cheap to build Wind farms are relatively cheap to build Farmers can receive an income from any electricity generated and the land can have other uses Farmers can receive an income from any electricity generated and the land can have other uses Produces no water or air pollution Produces no water or air pollution

7. Disadvantages of using your alternative Wind farms need a lot of land Wind farms need a lot of land The wind farms can have a significant visual impact The wind farms can have a significant visual impact Constant wind is needed Constant wind is needed
