Wind Turbines and Their Impact

Spirit Lake Schools in Iowa utilizes two wind turbines to generate energy, saving $120,000 annually. The larger turbine, standing 180 feet tall, contributes power to the grid, making the district an energy exporter. The turbines withstand winds up to 130 mph and shut down in strong winds. Physics teacher Jan Booy highlights the educational benefits, as students learn about energy and track reduced fossil fuel consumption. The initiative not only supports the school's budget but also serves as a practical learning lab, emphasizing sustainability and environmental responsibility.
