Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unequally heats the surface of the Earth. As hot air rises, cooler air moves in to fill the gap. As long as the sun shines, the wind will blow. And as long as the wind blows, people will manage it to power their lives.
Ancient sailors used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to make electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small part of the world's energy.
Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These devices look like giant airplane propellers(螺桨)on a stick. The wind spins the blades, which turn a shaft connected to a generator.
The biggest wind turbines generate enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines set up in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments decrease tax to encourage wind-energy development.
Some people think wind turbines are ugly and complain about the noise the machines make. The slowly rotating blades(螺旋风片) can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also changeable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is increasing sharply. Globally, generation more than quadrupled(四倍) between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind

Once kids hit the teenage years, parenting becomes more difficult than ever. Establishing effective house rules is one of the best ways to educate teenagers. House rules must respect teenagers’ desire to be independent and make sure they behave responsibly.

How can effective house rules be established?

First of all, get your teenager to take part in making the rules, which can help keep them motivated to follow them. Ask their opinion about what sorts of things they think are important when creating the rules and try to include some of their ideas.

When creating the list of rules, don’t list every single rule imaginable. Instead, try to limit it to the ten most important rules. I’ve seen some parents come up with several pages of rules which turn out to be more like a rule book rather than a list. Remember, it is important to make the list easy to remember and to be a basic guide.

Then, it is important that you write out the list of rules and hang them in a prominent (显眼的) location. Keeping the rules on the refrigerator or displayed somewhere where everyone can see them is a good reminder. Revise the rules whenever there’s a need, not very frequently though.

Explain clearly in advance what negative consequences will be in store when a rule gets broken. But ensure that none of your consequences are equal to abusive parenting. For example, take off the rule that says — “if you don’t get home by 11 at night, make arrangements to stay elsewhere until morning”. Let helping with small household chores like cleaning up their own rooms serve as consequences for disobeying rules.

Following these tips on establishing effective house rules accompanied by constant positive reinforcement (执行) will help improve your teenager’s behavior. Hope you can direct your teenager to become a responsible and independent person with the help of house rules!
