  • Working at a Wind Farm

    A wind farm, which is also called a wind power plant, is a group of interconnected wind turbines in the same location. A large wind farm may have of about 36 to about 100 individual wind turbines, and cover hundreds of square miles. A wind farm may be on land or even, offshore.

  • Why Put a Wind Farm Here?

    Geographic location is important when determining if there is enough wind. You need an average wind speed of around 25 km/h. The best places are gaps in mountains, open plains, tops of rounded hills and shorelines. Some of the top states in wind resources are: Texas, Kansas, Wyoming, and Iowa.

  • Kilo What?

    The unit of measurement for electricity is called a watt (W). A kilowatt (KW) is 1000 watts. A million watts is called a megawatt (MW). A wind turbine can generate from 250 watts to 5 megawatts of electricity, depending on its size and location.

  • The Grid

    Follow a class of students as they learn how the parts of a power grid produce and use electricity. It includes power generators, the users of electricity, switches that control the electricity, and the system of substations, power lines, and transformers that deliver the electricity.

  • How a Wind Turbine Works

    Follow a class of students as they learn how a wind turbine produces power. A wind turbine has 3 parts that we can see: the tower, the blades and a box behind the blades, called the nacelle. Wind energy spins the blades on a wind turbine which generates electricity.
