Wind+Power

**Be Blown Away By Wind Power ** By Khai and Serena **Wind Power is technically a form of Solar Power and wind is caused by heat from the sun. Wind power is created when the wind's kinetic energy is captured and converted to different forms of energy like electricity and mechanical power.[1]** ** Wind Turbine- ** **converts the energy of wind into kinetic energy**  **[10]**
 * VOCABULARY: **
 * [[image:http://www.petervaldivia.com/technology/energy/image/wind-turbine.jpg width="195" height="171"]] [6]

Electricty- ** **energy made available by the flow of electric charge through a conductor** [11] [7]  **[8]**
 * Wind Farm-** **a power plant that uses wind turbines to generate electricity** **[12]**

**[9]** **ADVANTAGES:**
 * Solar Power- ** **energy from the sun that is converted into thermal or electrical energy** [13]


 * Wind Power does not cause air, soil or water pollution
 * Wind Power is renewable and clean
 * Wind Power does not produce large amounts of hard to manage waste like Nuclear Power
 * Wind Power uses a natural source of power (wind) to produce electricty[1]


 * DISADVANTAGES: **


 * Wind Farms must be located on large tracts of land or along coastlines to capture the greatest wind movement
 * Wind Power sometimes conflicts with other priorities, for example agriculture, urban developement or water front views
 * Types of Wind Power such as wind farms can cost over 2.6 million dollars[1]

**THE CONSERVATION OF ENERGY OF WIND POWER:**

1. The kinetic energy in the wind causes the blades of the turbine to turn with kinetic energy 2. The kinetic energy of the blades causes the nacelle to turn with kinetic energy 3. The air from the nacelle flows into the gear box and uses kinetic energy to speed of the rotation 4. The rotation energy converts into electrical energy 5. The power of the generator is transformed into electrical energy 6. The national grid transmits electrical energy as power all over the country **HOW WIND POWER WORKS[4]:**


 * 1) Wind blows onto the blades of a wind turbine which causes them to turn
 * 2) The blades of the wind turbine turns a shaft that is inside a box that is at the top of the turbine also known as the nacelle
 * 3) The shaft goes into the gear box which then increases the rotation speed
 * 4) The generator used magnetic fields to convert the rotation energy into electrical energy.
 * 5) The power output goes to a type of transformer, which then converts the electricity coming out of the generator at about 700 Volts(V) in the direction of the right voltage for distribution system, typically at 33,000 V.
 * 6) The national grid transmits power around the country
