Wind turbines

Definition

Wind turbines are devices that convert the kinetic energy of wind into mechanical power, which can then be transformed into electricity. They are essential components of renewable energy systems, especially in regions where wind is abundant, such as the Arctic. Their role in providing sustainable energy sources can help reduce reliance on fossil fuels and minimize environmental impacts.
