Electrical Energy Supply by Different Energy Sources Essay

For electricity to be generated there is a need for a source of energy. Some of these sources will include Wind, liquid water forced to move at high velocity or steam projected at high pressure. The energy harnessed from these sources is used to run large turbine devices which in turn run attached generators that produce electricity that is the extracted and distributed. These sources produce mechanical and kinetic energy that is extracted by massive turbine devices that have blades spinning at great speeds. These blades are connected to the turbine shaft.

The turbine shaft is then connected to the alternator in the generator. The main job of the alternator is to use and absorb the kinetic or otherwise mechanical energy produced by the turbine device to create rotational motion and as a result produce electricity (OXLADE 2011). The rotation of the turbine shaft in turn causes the inner workings of the generator to rotate as well. These inner modules work collectively to cause relative movement between the magnetic and electric fields, which in turn generates electricity. The inner modules will include the stator which is the fixed and motionless module that comprises a set of electrical conductors convoluted in coils over an iron core and the armature which is the poignant module that produces a rotating magnetic field. In the space within the generator above identified as the stator, there are two polar field magnets that create a magnetic field.

These are positioned…
