RENEWABLE SOURCES OF

ENERGY

Wind power

Renewable sources of energy

Renewable sources of

energy are the sources

that are never exhausted,

such as geothermal

energy,hydroelectric

energy,solar energy, wind

power etc. They are

friendly to the environment

and very useful to people.

Wind power

Wind is a renewable

source of energy

which can be used in

producing electricity.

The use of wind

power does not

create pollution as do

the power plants.

History of wind powerThis type of power is also called ‘Aeolian power’ because

in ancient Greek mythology Aeolos was the god of wind.

Wind power was first exploited in sailing vessels used by

the ancient Greeks. As wind was blowing in the sails, it

gave the ship the necessary power to move.

Later the people exploited wind power with the creation of windmills which they used to grind wheat and make flour.

During the last 25 years

power generators

have been created,

their design based on

windmills ,but for a

different use ,that is

the production of

electric power. The

use of wind power

generators resulted in

the reduction of

pollution.

AdvantagesFirst, wind power generators

have replaced power

plants which produced

waste and fumes and now

it is them that produce

‘green’ electric power.

Besides it is a renewable

source of energy and it is

inexhaustible.

DisadvantagesOn the other hand wind power generators may kill

or injure the migrating birds. What is more they

cause noise pollution which means that they should be installed far from housing areas.

Finally the construction and maintenance cost is

too high for the amount of energy they produce.

The wind power in my area

In eastern Macedonia and Thrace there are two important wind farms and

one more is going to be built:

1)The wind farm of Psili Rahi was built in 2009. In it there are 12 wind

power generators. It is an important source of energy for the residents

of Drama.

2)The wind farm of Adriani.

3)The offshore wind farm in Lemnos is going to be built soon. It will be the

third biggest wind farm in the world and there will be put 81 wind

power generators which will generate 1,692.3 GWh every year.
