Wind Energy

Wind farms have hundreds of wind turbines to make energy from wind.
Wind Farm Making Energy
Windmills are used all over the world to generate 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.

So for example, if you're fifteen your range would be minimum 14 1/2, and your maximum would be 16. What is your method for <14 year olds, as well as 14 year olds themselves, as well as >16 year olds? My "method" is simple. Beginning at a suitable age, say 11, simply add two until you reach 15. Then, the age method is contingent upon the exact nature of the relationship, as well as the particular state's AOC. (Note, some states have very relaxed AOC's, so this method may not be suitable for all cases....this is based upon an AOC of 18) I don't do math, lololol. If I like you, I like you, normally though, I'd say 3 years older, while you're in school, then when you get out into "the real world" it can go up to as far as you want to. The thing is though, in some states, anything past holding hands can potentially be illegal if, using your method, one is 16 and the other is 19. That's only three years. However you are right, but I wouldn't use my method until I'm outta school. And besides, normally like them my age or a year or two older. 3 years can make a huge difference. Fifteen and Eighteen, Fourteen and Seventeen, Twelve and Fifteen etc. Yes. but think about it 23-26, that's not a big difference when you get outta school. Nobody will look at you weird, maybe for when you're in school. but out of school age is just a number.

Like having a Manic episode, depression. Stuff like that. Is that not Happy.Sad.Happy.? Happiness can be a form of Mania, which does actually mean happy.sad.happy. Yes, but there is also a...kinda like an angry manic mood. Where you're more easily annoyed and sometimes more likely to be violent. I know anger can be associated with Mania, but isn't that also angry.sad.angry.? Also, not all Mania Is shown by anger, maybe in your personal life there has been this, but it is not always the case.
