A wind turbine is a device that converts kinetic energy or moving energy from the wind into electricity. A group of wind turbines is called a wind farm. On a wind farm, turbines provide power to the electrical grid. These turbines can be found on land (onshore) or at sea (offshore).
Wind turbines are manufactured in a wide range of shapes and sizes, but the most common design is the one with 3-blades mounted on a horizontal axis. Their output ranges from as small as 100 kilowatts, to as big as 12 megawatts. They can be placed in a huge range of locations: on hills, in open landscapes, fixed to the bottom of the sea and we can even have floating turbines in deep waters!
