	[[Wind turbine]]s operate by transforming the [[kinetic energy]] in [[wind]] into [[mechanical power]] which is used to generate electricity by spinning a generator. These turbines can be on land, or can be offshore wind turbines. These turbines have three main components. The first of these are the rotor blades which are shaped like aircraft wings to catch the air, causing the blades to turn. The second component is the nacelle, a set of gears and a generator that transforms the blade rotation into electrical energy. Finally, the tower is the large stand that the blades and nacelle are mounted on.<ref>Energy Center of Wisconsin. (September 2, 2015). ''Parts of a Turbine'' [Online].

	In this case, water held behind a [[hydroelectric dam\|dam]] is released and allowed to fall on a turbine, generating electricity when connected to a [[generator]]. These turbines are essential in the area of [[hydropower]] - the process of obtaining [[power]] from water.

These turbines are essential in the area of [[hydropower]] - the process of obtaining [[power]] from water.

	Generally, the construction of hydroelectric turbines is the same. A row of blades is fitted to some rotating shaft or plate. Water is then passed through the turbine over the blades, causing the inner shaft to rotate. This rotational motion is then transferred to a generator where electricity is generated. There are a variety of different types of turbines that are best used in different situations. Each type of turbine is created to provide maximum output for the situation it is used in. There are many factors that must be investigated to determine which turbine should be used. These factors include [[hydraulic head]], [[~~flow rate~~]], and the cost.<ref>BrightHub Engineering.
