Eastern Wind Data Set Provides energy professionals with a consistent set of wind profiles for the eastern United States. Again, this diagram shows an example of an up-wind, horizontal axis wind turbine that may be made of steel and potentially stand several stories tall. excluding turbulence) can be described by a so-called Weibull distribution: with a shape factor k and a scaling factor A. The wind turbine blades can be 40 meters to 90 meters long. Approximately 2% of the solar energy striking the Earth’s surface is converted to kinetic energy in wind. Sankey Diagram Energy Wind. Make an overhead of the wind turbine diagram (Figure 1). The amount of electricity that a wind turbine can generate depends mostly on the size of the turbine, the area swept by the turbine blades, the air density, and the wind speed. Here is a post on wind-to-gas-to-power. At its most fundamental roots, a wind turbine works by allowing wind to rotate a turbine generator. The diagram of the wind turbine above is Then, it transfers the rotational energy into the high-speed turbine shaft and into the generator. Transmission wiring and conduit allow you to transfer energy from where it’s made to where it’s stored and used. So, to calculate wind power output or the amount of wind electricity that is expected to be produced from a wind turbine you will need a short list of dependent variables: (Cp) – Turbine efficiency coefficient, maximum of 0.593, (ρ) – Air Density, measured in pounds/cubic foot, (A) – Area of rotor blade, measured in square feet, (k) – k is a constant that equals 0.000133, this coverts the answer into kilowatts, (P) – Power Output, the independent variable we wish to calculate, in kilowatts. A tower supports a wind generator, getting it up into the smooth, strong wind that’s needed to generate meaningful amounts of electricity. (9) The anemometer is a device that measures wind speeds. How Much Energy do Wind Turbines Produce? where z0 is an index that describes the roughness of the surface. It’s high rotating speeds are what spin the turbine generator. In 1919, German physicists Albert Betz discovered that no wind turbine could physically capture more than 59.3% of the kinetic energy of the wind. Make a sample wind turbine/pinwheel to show the students. Discussion Questions; Science. Inside a Hydropower Plant; Solar Power. Wind Resource and Potential. Two sets of percentage values are given, apparently for two different scenarios. They are called this because they use turbine generators to generate the electricity. A wiring diagram is a schematic which uses abstract pictorial symbols to demonstrate all the interconnections of components in a system. Energy flow diagrams can be extended to include other forms of energy, such as light energy, heat energy and sound energy. No Spam. How Solar Power Works Diagram; Solar Energy Home; Wind Power. The map shows different wind speed regions. Wind energy. Wind power may be never-ending, but it's not omnipresent. Day One. Wind isn't for everyone. Even small errors in estimation of wind speed can have large effects on the energy yield, but also lead to poor choices for turbine and site. Wind is produced as a result of giant convection currents in the Earth's atmosphere, which are driven by heat energy from the Sun. Wind Energy Diagram could help you to show share of wind power in total electric power network. Make enough copies of the Wind Energy KWL Chart, the Pinwheel Worksheet and the Pinwheel Template (attached) for each to student to have one. Wind has the potential to generate far more than 1 percent of that electricity. With the above variables, the equation to calculate the wind electrical output of a wind turbine is: Note the relationship of each variable from the equation and how it relates to how a wind turbine works. Pass out the Wind Energy KWL Chart. A 5 megawatt wind turbine could produce around 15 million kilowatts hours of wind electricity in one year, which could provide power to over 1,000 households. (8) The turbine generator is the most essential part of how a wind turbine works. mean wind speed: Only interesting as a headline figure, but does not tell how often high wind speeds occur. GE is leveraging that growth for the benefit of the entire wind industry with an investment of more than $400 million to develop the most powerful offshore wind turbine—an investment that will also drive down the LCOE of offshore wind farms, helping make offshore wind energy more competitive for our customers.
