Introduction
The idea of using water to power something came in the simplest form with the concept of using of an object to push water through thus creating motion then transferring it into energy. Then taking that energy into turning an object such as corn that could be grounded into meal or wheat turned into flour. As time progressed so did technology we learned quickly that we harness this into electricity with the help of dams. The history of the water turbine first we need to start in Medieval times with the creation of the water wheel which was used to generate energy with the pushing of water with a massive wooden wheel but due to its size prevented it from a being a practicable application, so over roughly a hundred year time span, communities and inventors developed a more mobile water turbine. The word turbine was used by Frenchman Claude Burdin in the 19th century, the term Turbine which is derived from the Latin word of whirling or vortex. Nearing the late 19th century about every water used invention was basically reaction machines; a reaction machine needs to fully contain the water during energy transfer. Now we jump to today’s water turbine they are ninety percent more efficient than older ones.
The Design of a turbine
The Main Components in a turbine are the blades, generator, shaft, rotor and stator. The two types of turbines are impulse and reaction, the most widely used is the reaction when using a reaction turbine it must maintain the water pressure for it to work. An example of a reaction turbine is the Francis turbine, which uses different pressures to move the water through the blades it is the most widely used turbine today. An example of a Impulse is a Pelton wheel its uses spoon like bucket to ca...

Conclusion
In addition, a turbine has history and pro and cons, some see a great benefit some might go for other power alternatives such as wind but it ‘s a great invention and need for many people who now get their electricity from Water power. It is an environmental friendly method that helps reuse are carbon foot print on the environment. A water turbine can be uses for a renewable energy source and are designed to run for decades. They already produce significant amounts of the world's electrical supply. In the end, a Water turbine Engine is a device with blades at one end and electromagnets at the other. A water turbine is there for creating electricity from water movement.
Some are more efficient than others, and some have more pros to them than cons. Wind power for example, generates electricity through huge spinning turbines. These huge turbines have blades that fit on the back of semis. Most wind turbines have three blades and sit atop a steel tubular tower. Their size ranges from about 80-foot-tall turbines that can power a single home, to utility-scale turbines that power hundreds of homes. Today’s wind turbines are like highly developed windmills.
MR: First of all, to get a new energy system, new jobs have to be created; so, economy grows up. Secondly, it is estimated that energy can get cheaper in a 20-year term. Lastly, having clean energy means having a cleaner world, which is positive to ourselves because it makes us healthier (“The Solutions Project”, 2011).
Besides the long known history, the ways electricity is generated through wind turbines are truly simple, too. “Turbines catch the wind's energy using blades which are mounted on a shaft. The shaft is connected, normally via a gearbox, to a generator which produces electricity. The blades and shaft are connected to the

A simple Brayton Cycle Gas Turbine is shown in figure 1. It consists of mainly three components :
Steam turbine is a device used to covert thermal energy (Steam) into mechanical energy, then after converted to Electrical energy. In turbine, casing is the main component as it hoses blades, rotor, nozzles and diaphragms. Steam turbine casings operates at very high temperature and pressure which results in large stress strain distribution. If the contact pressure is not attained then it leads to leakage of steam which further can cause explosion.
With alternate energy sources becoming more and more necessary and desirable, not only does the future hold promise for a cleaner environment, but many companies and entrepreneurs have the potential to make billions of dollars should hydrogen, nuclear, or some other alternative source of energy become implemented worldwide.
In everyday life, there are things that one needs to survive. And sustainability problems arise every day. One such problem is energy loss. The world is using up a lot of energy and new ideas need to be formed to help the rest of the world and the future of the generations that are to follow, to survive. With that the problem is that people use up energy and they do not use it efficiently. Therefore scientists are needed to find ways to deal with the sustainability problem that is arising. That is where wind turbines are used to generate this energy but the actual wind-turbines are very large, loud and they kill birds, thus new designs need to be found in order to help energy usage and to bring the size and structure of the wind turbines to a smaller scale to prevent injuries to nature and the species around it.
Wind turbines can be very useful in bringing energy into your home. They are especially useful when solar panels aren't working. They take the wind speed from oceans, lakes, dugouts, or rivers and turn it into energy. To use the wind turbines most efficiently you should set up a wind power system.
The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
Hydro power is one of many examples of alternative energy source. Hydro power is producing energy by moving
...ination, hydrogen fuel and solar energy (World Economic Forum 2014). These are technologies that closely related to environmental and recourse preservation, which help the society switch to use renewable energy.
Next, hydro-electricity is electricity produced by moving water, flowing past a turbine connected to a generator (“Hydropower”). According to Nationalgeographic.c...
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
Wind turbines are a great source of energy around the world. Wind turbines produce wind energy that can be used to power our homes. Wind turbines convert kinetic energy into mechanical power. Then this mechanical power gets generated into electricity. Wind turbines make energy by the wind turning the large blades, which spin a shaft that is connected to the large blades, which then operates the generator making electricity.
