The diagrams below show the design for a wind turbine and its location. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagrams depict the features of a

wind

turbine

as well as

the suggested positions for generating

electricity

power

.

Overall

, the technology of the

wind

turbine

comprises five parts, yet, the locations of the

wind

turbines affect the level of

electricity

output. In order to generate

electricity

power

, the

wind

turbine

is installed vertically on the ground or the sea. The

wind

turbine

consists of a tower, generator,

wind

sensor

,

blades

, and a computer. The tower itself is made of steel to support the upper parts of the

turbine

;

however

, the

blades

are made of fibreglass or wood. The

wind

turns the

blades

,

then

the spin will be recorded by the

wind

sensor

.

This

sensor

functions in determining the speed and the direction of the

blades

.

In addition

, when the blade is spinning, the generator will operate to produce

electricity

power

of about 1.5 megawatts. On a separate part, the computer which is installed on the ground next to the

turbine

, stores the information from the

wind

sensor

and modifies the direction and angle of the

blades

. In order to have a greater amount of

electricity

, the

wind

turbine

is recommended to be positioned in a higher location. To illustrate, a domestic

wind

turbine

which is smaller can only produce a minimum amount of energy at 100 kilowatts.

Hence

, it is encouraged to install the

wind

turbine

on top of the mountain so that the

power

of the

electricity

can be maximised, compared to the other areas

such

as on the sea.
