Wind turbines convert the kinetic energy of wind into mechanical or electrical energy. Modern wind turbines are much more efficient than older designs, able to generate 250-300 kilowatts compared to older models generating around 30 kilowatts. Wind turbines work by using wind to turn blades which spin a shaft connected to a generator, producing electricity. They are mounted on towers to access stronger winds higher off the ground. While wind energy has advantages like being renewable and producing no emissions, it also has disadvantages like dependence on wind conditions and higher initial costs than some other energy sources.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
2. Wind in action:
When wind strikes an object, it exerts a force in an attempt to move it out
of the way. Some of the winds’ energy is transferred to the object, in this
case the windmill, causing it to move.
Wind Today!!!
Windmills are used for pumping
water from deep underground.
Modern wind turbine is the result of
design and material advances made
during the 1980s and 1990s, which
enabled wind turbines to become
increasingly efficient.
Today, wind turbines are size same
as the traditional European windmill.
It can generate 250 to 300 kilowatts of
power- a nearly tenfold increase in
efficiency.
History of Wind usage:
one of the earliest energy resources.
Recorded in history, first to power boats
and grind grain, later to pump water, press
oil, saw lumber and make paper.
Windmills were mentioned at the
beginning of Islamic civilization (7th century).
Windmills were developed in Persia and
used paddles made of bundled reeds.
Egyptians may have been the first to go up
the Nile river around 4th century B.C,
powered by wind.
Ancient Chinese used vertical axis
windmills to grind grain and pump water.
Windmills were introduced to Europe by
the crusaders around 1300 A.D
*windmills used for pumping water.
3. Wind turbines convert the kinetic energy in the
wind into mechanical power.
This mechanical power can be used for specific
tasks (such as grinding grain or pumping water)
or a generator can convert this mechanical
power into electricity.
A wind turbine works the opposite of a fan.
Instead of using electricity to make wind, like a
fan, wind turbines use wind to make electricity. The
wind turns the blades, which spin a shaft, which
The energy in the wind turns two or three
connects to a generator and makes electricity.
propeller-like blades around a rotor. The rotor
is connected to the main shaft, which spins a
generator to create electricity.
Wind turbines are mounted on a tower to
capture the most energy. At 100 feet (30
meters) or more above ground, they can take
advantage of faster and less turbulent wind.
6. Specific components
Description
Wind turbine
2. Is the rotor. The rotor provides the
blades to rotate.
4. This is brake. It’s very important to
have a brake in a wind turbine, if
something is wrong or it is going to
fast. Then it will brake and stop the
wind turbine. 5. is a low-speed shaft, it
goes into a big cog wheel and this goes
into a smaller cog wheel. The small
cog wheel rotates faster than the big
cog wheel.
7. This is the generator. It’s almost
like a generator in a car.
13. It’s a yaw draw, it makes the wind
turbine rotate in the wind direction.
15. Is the tower. The entrance is
placed in the bottom of the tower
7. How the does a wind turbine works?
Wind turbines operate on a simple principle:
The energy in the wind turns the propeller-like blades
around a rotor. The pitch of the blades makes optimum
use of the wind direction.
The rotor is connected to the main drive shaft, which
spins a generator to create electricity.
Wind turbines are mounted on a tower to capture the
most energy. At 30 metres or more above ground, they
can take advantage of faster and less turbulent wind.
Wind turbines can be used to produce electricity for a
single home or building, or they can be connected to an
electricity grid for more widespread electricity
distribution.
8. Advantages and Disadvantages???
Advantages:
No pollution.
Lowest prices renewable resources
Don’t produce atmospheric
emissions that cause acid rains and
green house effects.
Disadvantages:
Depending on how energetic a wind site is, the wind
farm may or may not be cost competitive.
Wind energy cannot be stored (unless batteries are
used)
Good wind sites are often located in remote locations
Wind resource development may compete with other
uses for the land and those alternative uses may be more
highly valued than electricity generation.
sometimes birds have been killed by flying into the
rotors
10. Onshore advantages
A regular onshore turbine
last for around 20 years
Normally it takes about 2-3
months before the wind
turbine has paid itself back.
This also includes the
energy, which were used to
produce, install, maintain
and remove the wind
turbine.
Cheaper foundation
Cheaper integration with
electrical-grid network
Onshore disadvantages
Wind turbines are noisy
Each one can generate
the same level of noise
as a family car
travelling 70 mph
Some people thinks
that the large towers of
wind turbines destroys
the view of the
landscape
11. Onshore or offshore?
Offshore advantages
Offshore disadvantages
• A offshore wind turbine is • More expensive to built
stronger than a onshore
• More difficult to
turbine. It lasts around
maintain and access
25-30 years, and produces
about 50 % more energy
than a onshore turbine.
• When a strong wind blows,
it produces around 3-5
MW per hour.
• Higher and more constant
wind speed
13. General advantages
• Wind energy is friendly to the surrounding
environment, as no fossil fuels are burnt to
generate electricity from wind energy
• Wind turbines requires less space than
average power stations.
• When combined with solar electricity, this
energy source is great for developed and
developing countries to provide a steady,
reliable supply of electricity
14. General disadvantages
• The main disadvantage regarding wind
power is down to the winds unreliability
factor. In many areas, the winds
strength is not enough to support a wind
turbine
• Wind turbines generally produce allot
less electricity than the average fossil
fuelled power station, which means that
multiple wind turbines are needed to
make an impact.
