Wind B y: Andrea Goodson, Brittany Donna & David Hooper
Introduction • The energy source wind, has always been here on earth. • Wind is just simply air in motion • Wind is caused by the uneven heating of water and land. • The air over the land, warms, expands and rises, then cool air over the water moves in to take its place.
History Of Wind • Windmills are wind driven machines • Europeans built the first windmill in the 1100s • In 1888 Charles F Brush built the first large windmill in Cleveland,OH • The First wind farms were built in California, Denmark & Germany
Obtaining Production • Wind turbines have to face the wind to generate electricity • Turbines are usually built in rows • There are thousands of wind farms over 70 countries • Some wind farms are located in Texas, Montana, Iowa, Minnesota and Oklahoma
Advantages • Wind is clean, environmental friendly and free • Wind is the fastest growing energy source world wide • Every year, wind produces more electricity then the year before that
Disadvantages • People think turbines make a lot of noise and affect the view of the landscape • Wind turbines produce little energy our country uses • Underwater construction is hard and expensive • Wind farms don’t always produce electricity
Future technology • Wind farms on the water are hard and expensive • Turbines in the water would not disturb people and wildlife • An underwater turbine will use ocean currents to make electricity
