Wind power has great potential to create renewable energy on a large scale. Already implemented in a number of areas across the United States, some experts estimate that wind power has the potential to supply up to 20 percent of all world power.
Wind power does have its detractors, however. The propeller blades of wind turbines have been accused of increasing bird mortality; an issue that can be avoided with solar power or hydrologic power. Wind turbines have also created conflict in towns where residents argue that the tall structures obstruct the skyline and deflate property values.
Students can build their own wind turbines to get a better idea of how wind power is generated. The KidWind Project outlines instructions on how to construct beginner, intermediate, and advanced turbines.
