wind rurbine history

Wind energy conversion is a
spellbinding field to study, if
only because its past has
been so checkered and its
exact future is so vague.

But unlike many of these
other industries, wind
energy has been around for
thousands of years and it's
a technology that has been
reinvented many times.

WHERE and WHEN
did Wind Energy start?

500 B.C.
The development of
sail boats led directly
to the development
of the first recorded
wind powered device
in Persia (the Middle
East)…

500 B.C.

Sails were used to
drive a mill stone
for the grinding of
grain. These were
seen first in Persia,
500 BC.


500 B.C.
Some versions
were also used to
pump water for
drinking water and
for simple
irrigation of
agricultural land.

1300 – 1850 A.D.

This type of
windmill design
became familiar
in Europe
between 1300
and 1850 AD.

1300 – 1850 A.D.
The windmill
design is much
more like the
traditional
windmills we see
even today.

1300 – 1850 A.D.

It was designed
particularly for
the large scale
milling of grain.


19 th Century

In the USA wind
powered devices
like the one shown
in the illustration
were developed to
pump water.

19 th Century

These were
especially functional
in bone-dry areas
where deep wells
were essential to
find drinking water

19 th Century

In the 1800s, the
Halladay windmill
was very trendy with
thousands made.

19 th Century

This basic design was
reliable and was
used even up to the
1940s.

19 th Century

A large version of
this design had
rotors (propellers) of
18 meters in length.

20 th Century (USA)

First Use of Wind for
Large-Scale
Generation of
Electricity

20 th Century (USA)

With the development of
electrical power,
scientists and
technologists developed
ways of producing
electricity through the
use of wind generators
(also known as turbines).

20 th Century (USA)

In the 1930s one of the
largest experimental
machines, called the
Palmer-Putman
machine was first used.


20 th Century (USA)

This was capable
of producing 1.25
megawatts of
electricity.

20 th Century (USA)

However, due to the
materials available at the
time, its effectiveness was
reduced to a great extent
and made the machine
hard to maintain.

20 th Century (USA)

It had 50 meter
rotors which were
large compared to
other designs.

20 th Century (Denmark)


Due mainly to the fast rise
in oil prices throughout the
late 1970s and 1980s,

the fact that using fossil
fuels to produce electricity
causes pollution,

which can damage the
environment and cause
global warming,


The development of wind
generators (turbines)…


THE RISE OF MODERN
WIND TURBINES

Modern wind turbine generators
are robust, sophisticated high-tech
machines designed to convert the
power of the wind into electricity.

They generally consist of a rotor
with three blades.

A nacelle, which typically
contains a gear box, generator,
brake, yaw motor, and yaw
drive.

And an
anemometer for measuring
wind speed.

Now, here are some
Modern Wind Turbine
DESIGNS
