Wind Energy

Wind isn't just some uncontrollable part of nature that messes up our hair or sucks up Dorothy, Toto and anything else in its way. It can't be trained but it can be put to work. The kinetic energy of wind can be changed into other forms of energy. When a boat uses a sail to push it, that is one form of wind energy at work. Farmers have been using wind energy for years to pump water from wells and turn large stones to grind wheat or corn - just like a water wheel.

Wind is also used to make electricity. Blowing wind spins the blades on a wind turbine - just like when you blow on a toy pinwheel. When the blades turn, the turbine is operating and electricity is generated. The turbine has a brake, so if the wind blows too hard, the brake can stop the blades from being damaged. Some wind turbines are up to 10 stories high and have blades as long as 50 feet. Wind turbines don't create any pollution but they can be pretty noisy.

Wind has to blow at speeds of 12 to 14 miles per hour to turn the turbines fast enough to create electricity. The turbines usually produce about 50 to 300 kilowatts of electricity each. Kilo means 1,000, so a kilowatt is 1,000 watts. You can light ten 100 watt light bulbs with 1,000 watts. This means a 300 kilowatt wind turbine could light up 3,000 light bulbs that are 100 watts.

Wind turbines are grouped together in what are called wind farms. About 30 percent of the world's electricity is made from wind in California. They have three large wind farms that create enough electricity to supply a city the size of San Francisco with power. Two countries that use a lot of wind energy are Denmark and Germany.

The world's largest wind machine is on the island of Oahu, Hawaii. The windmill has two blades, 400 feet long, on the top of a tower which is 20 stories high.

I Just looked it up and Here is what i found....: At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. Over the 8,000-year period up to 1 A.D. it grew to 200 million (some estimate 300 million or even 600, suggesting how imprecise population estimates of early historical periods can be), with a growth rate of under 0.05% per year. A tremendous change occurred with the industrial revolution: whereas  it had taken all of human history until around 1800 for world population to reach one billion , the second billion was achieved in only 130 years (1930), the third billion in less than 30 years (1959), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987). During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion. In 1970, there were roughly half as many people in the world as there are now. Because of declining growth rates, it will now take over 200 years to double again. So, There are definitely more people on earth now...huh?  Bravo
