Turbines are engines that extract the energy from a liquid or air flow. Turbines are really important for any society in the world because they are the most common kind of technology used for producing electric energy. To be more exact, turbines are rotator engines which spin thanks to the constant flow o water or any other liquid, or also because of the flow of steam. I think that it is very interesting on how the use of a very simple machine could actually be the basis of actual societies.
These turbines are used in almost every source of energy, for example in the wind energy; wind constantly moves the huge turbines located at the top of windmills, these turbines move or power up a generator located in the windmill which is in charge of transforming the movement into energy or in this case electricity. Another example is the geothermal energy, in which hot water and steam (heated by the earth’s core), come out from the land and moves some turbines located inside geothermal plants, these turbines also power up some generators and produce electricity. Hydroelectric energy, nuclear energy, solar energy and even the burning of fossil fuels depend on the turbines for the production of electricity. My point is we could say that the humankind totally depends on the use of turbines for obtaining electric energy. I didn’t know the real importance of these not very complex artifacts in our society until I read some chapters from the book Our Choice from Al Gore.
