Wind+2

Wind power is turning kinetic energy (moving energy) into mechanical energy.
 * Definition of Wind Power:**

Wind.
 * What is its source?**

The Sun heats our atmosphere unevenly do to land and water, so some patches become warmer than others. These warm patches of air rise, other air  blows in to replace them
 * Where does it come from or how is/was it formed?**

Wind “pushes” the blades, which turns a generator, which is kept in the back of the three or four blades, to make energy.
 * How is this source used to make energy?**

Wind turbine Windmill Wind propeller Sails, tower, generator
 * What equipment do you need to convert the “raw material” into energy?**

There are two types of windmills horizontal and vertical
 * Different Types of Windmills:**

//**Horizontal:**// A typical horizontal wind machine stands as tall as a 20-story building and has three blades that span 200 feet across.

The type of vertical wind machine typically stands 100 feet tall and 50 feet wide. Vertical-axis wind machines make up only a very small percent of the wind machines used today.

 * Inside a Windmill:**

“Wind farm”, data showing strong, steady winds, coastal areas, “at the tops of rounded hills, open plains and gaps in mountains - places where the wind is strong and reliable. Some are offshore. Mostly farms.
 * Real-life example of where it is used, and how.**

FREE, NO GREENHOUSE GASES, NEED NO FUEL Land beneath still can be used, usally for farming Tourest attractions, remote areas
 * Advantages:**

Wind not predictable Coastal land expensive Unslighty Kill birds- rare Bad tv reception Loud noises
 * Disadvantages**:

An average wind speed of around 25 km/h is needed to generate wind power.
 * Unusual Fact:**
