▪ Wind energy (or wind power) refers to the process of creating electricity using air
flows that occur naturally in the earth’s atmosphere. Modern wind turbines are used
to capture kinetic energy from the wind and generate electricity.
▪ When the wind blows past a wind turbine, its blades capture the wind’s kinetic
energy and rotate, turning it into mechanical energy. This rotation turns an internal
shaft connected to a gearbox, which increases the speed of rotation by a factor of
100. That spins a generator that produces electricity.
▪ A typical modern turbine will start to generate electricity when wind speeds reach
six to nine miles per hour (mph), known as the cut-in speed. Turbines will shut
down if the wind is blowing too hard (roughly 55 miles an hour) to prevent
equipment damage.
▪ Utility-scale wind
▪ Distributed or small wind
▪ Offshore wind
▪ Utility-scale wind:Wind turbines that range in size from 100 kilowatts to several
megawatts, where the electricity is delivered to the power grid and distributed to
the end user by electric utilities or power system operators.
▪ Distributed or "small" wind: Single small wind turbines below 100 kilowatts that
are used to directly power a home, farm or small business and are not connected to
the grid.
▪ Offshore wind: Wind turbines that are erected in large bodies of water, usually on
the continental shelf. Offshore wind turbines are larger than land-based turbines
and can generate more power.
▪ Windmills generate mechanical energy, but they do not generate electricity. In
contrast, modern wind turbines are highly evolved machines with more than 8,000
parts that harness wind's kinetic energy and convert it into electricity.`
▪ Unlimited, Free, Renewable Resource
▪ Economic Value
▪ Maintenance Cost
▪ Non-polluting Way To Generate Electricity
▪ Harmlessly Generate Electricity From Wind Passing By
▪ Ability To Place Turbines Wherever Necessary
Wind is a natural occurrence and
harvesting the kinetic energy of
wind doesn't affect currents or wind
cycles in any way.
Wind creates jobs. The U.S. wind
sector employed more than 100,000
workers in 2016, and wind turbine
technician is one of the fastestgrowing American jobs of the
decade. According to the Wind
Vision Report, wind has the potential
to support more than 600,000 jobs in
manufacturing,
installation,
maintenance,
and
supporting
services by 2050.
Land-based utility-scale wind is one
of the lowest-priced energy sources
available today, costing between two
and six cents per kilowatt-hour,
depending on the wind resource and
the particular project’s financing.
Because the electricity from wind
farms is sold at a fixed price over a
long period of time (e.g. 20+ years)
and its fuel is free, wind energy
mitigates the price uncertainty that
fuel costs add to traditional sources
of energy.
Wind energy is far more ecofriendly
than the burning of fossil fuels for
electricity. Currently, the United
States, along with other countries,
remains dependent on fossil fuels
imported
from
unstable
and
unreliable nations.
electricity to make wind like a fan
wind turbines use wind to make
electricity. Wind turns the propellerlike blades of a turbine around a
rotor, which spins a generator, which
creates electricity.
After performing research and
finding areas that have adequate
wind, experts may place the
turbines in desired areas.
Wind is actually a form of solar
energy. Winds are caused by the
heating of the atmosphere by the
sun, the rotation of the Earth, and the
Earth's surface irregularities. For as
long as the sun shines and the wind
blows, the energy produced can be
harnessed to send power across the
grid.
▪ High Initial Cost
▪ Technology Immaturity
▪ Aesthetic Impact
▪ Wildlife
▪ Remoteness Of Location
▪ Noise
▪ Safety At Sea
Constructing turbines and wind
facilities is extremely expensive.
High cost of energy can, in part, be
addressed directly with technology
innovations that increase reliability
and energy output and lower system
capital expenses.
Many people are concerned with the
visual effects that wind turbines have
on the beautiful scenery of nature.
They believe that giant wind
turbines distract viewers from the
beautiful surroundings.
Wind turbines may be dangerous to
flying animals. Many birds and bats
have been killed by flying into the
rotors. Experts are now conducting
research to learn more about the
effects that wind turbines have on
marine habitats.
Although this may be an advantage
(placing wind turbines in desolate
areas, far away from people), it may
also be a disadvantage. The cost of
travel and maintenance on the
turbines increases and is time
consuming. Offshore wind turbines
require boats and can be dangerous
to manage.
Some wind turbines tend to generate
a lot of noise which can be
unpleasant.
In the darkness/at night it may be
difficult for incoming boats to see
wind turbines thus leading to
collisions.
