The diagrams demonstrate how a hydroelectric dam and wave-air generator are used to produce electricity.
Overall
, two methods of generating energy are applied in different locations with various essential equipment and their operations are quite simple.
Having looked at the first given diagram, Linking Words
it is clear that
a hydroelectric dam is installed near the river where water easily flows into and is stored in the reservoir. The process begins when the gate opens to let it in. Linking Words
In addition
, the width and angle of the penstock decide its speed which turns the turbine and spindle. When the spindle rotates in the generator, electricity is generated and Linking Words
then
distributed to power lines. Linking Words
Also
, the water is released into the river which ends the process.
In terms of producing energy by using wave-air generation, it is apparent that the method is applied in the ocean. Two chambers are placed at sea to take advantage of the waves. When waves go into the lower chamber, the air is pushed into the upper chamber that turns turbine and spindle. As it rotates in the generator, electricity is produced. Simultaneously, the air is released from the upper chamber.Linking Words
