Flowing water is directed on to the blades of a turbine runner, creating a force on the blades. Since the runner is spinning, the force acts through a distance (force acting through a distance is the definition of work). In this way, energy is transferred from the water flow to the turbine. Water turbines are divided into two groups: reaction turbines and impulse turbines. The precise shape of water turbine blades is a function of the supply pressure of water, and the … Web13 jan. 2024 · Tidal stream energy uses turbines to extract energy from moving water in oceans and rivers, with UK waters holding around half of Europe's tidal stream resource.
