For human development to continue, we ultimately need to find sources of renewable or virtually inexhaustible energy. For the purpose, Turbines play a very important role. Turbine is a rotary engine that uses a continuous stream of fluid (gas or liquid) to turn a shaft that can drive machinery. Different technologies are used by different kind of turbines for various applications.

Improvements in technology continue to make turbines cheaper and more efficient. Turbine technology has been evolving over a long period of time. Further restructuring of the world turbine industry is likely in a persistently challenging market environment.
