Generators - How They Make Energy

   Making Energy: How a Generator Works

  Whether you use fossil fuels or an alternative form of energy, one of the key components of the process is usually a generator.

  Without a generator, you cannot produce electrical energy - you can only produce mechanical energy. For example, when flowing water moves a waterwheel, this is mechanical energy. The waterwheel was sometimes used hundred of years ago in mills to directly crush grains by connecting the wheel moved by water through a serious of gears to a mechanism that did the crushing work.

  However, by using a generator, we can create the same amount of power, but store it and send it to homes to use for heat, light, and operating anything that needs to be plugged into the wall.

 
By using the waterwheel example, generators are easy to understand. They work in much the same way with other forms of energy as well.

Everything starts with a turbine of some sort
. In a water wheel, the wheel that is being pushed by the flowing river or waterfall acts as the turbine blades.

  Basically, whatever process you are using, the blades are the parts that spin. The turbine is connected to a shaft, which also spins and causes the rotor to spin as well.

  The rotor is made up of a series of large electromagnets and is found inside a stator, or roll of copper wire. The electrical charge is created by the interaction between the copper wire and magnets. This current can then be sent as electricity to do work in homes.

  Generators work in a similar way when using wind power, except the moving air causes blades to spin, rather than water.

  In other forms of energy, where steam is created, such as geothermal energy, nuclear energy, and ocean thermal energy conversion, the air expands from the heat of the boiling liquid and this moving air turns the turbine.

  This is also how fossil fuels work. The process of using turbines and generators itself does not cause pollution. Rather, it is the by-product from the chemical reaction used to produce the steam that turns the turbine (in this case, burning fossil fuels like oil and coal).

  Therefore, using generators to create electricity with alternative forms of energy is clean and safe for the environment.

  As this process becomes more efficient and cost-effective, using water and wind turbines could become more popular to create energy for the world's power supply.
