Detailed explanation-1: -A turbine is a device that harnesses the kinetic energy of some fluid-such as water, steam, air, or combustion gases-and turns this into the rotational motion of the device itself. Turbines are generally used in electrical generation, engines, and propulsion systems.

Detailed explanation-2: -Large turbines are used to generate electricity. As the name implies, a steam turbine is powered by steam. As hot, gaseous steam flows past the turbine’ spinning blades, steam expands and cools, giving off most of the energy it contains. This steam spins the blades continuously.

Detailed explanation-3: -The wind – even just a gentle breeze – makes the blades spin, creating kinetic energy. The blades rotating in this way then also make the shaft in the nacelle turn and a generator in the nacelle converts this kinetic energy into electrical energy.

Detailed explanation-4: -The workings of a wind turbine are much different, except that instead of using a fossil fuel heat to boil water and generate steam, the wind is used to directly spin the turbine blades to get the generator turning and to get electricity produced.

Detailed explanation-5: -Offshore Wind Turbines Can Float: A number of companies are developing innovative floating offshore wind platforms for use in deep waters. Four kinds of floating platforms are spar-buoy, tension leg platform, semi-submersible, and barge. About 80% of projects plan to use semi-submersible platforms.
