Air in Motion. Wind energy is the transformation of the kinetic energy of the wind into mechanical or electrical energy that can be harnessed for practical use

2. MODERN TECHNOLOGY
New urban rooftop windmills
are new windmills with a
smaller and quieter design.
These windmills are designed
to be more efficient with wind
patterns occurring in cities.
They are able to turn at wind
speeds as low as 8 mph
What is Wind Energy?
Wind energy is the
transformation of the
kinetic energy of the wind
into mechanical or
electrical energy that can
be harnessed for practical
use
4. EARLY HISTORY/INVENTORS & INNOVATORS
The first recording of a windmill came from a Hindu book dating back
to about 400 B.C.E.
Scientists believe that the first windmills created to do work were
created in China 2000 years ago. There is no written history of this
however.
The first recorded windmills that were created to do work are from
seventh-century Persia.
The first historical reference to Chinese windmills was in 1219. This
is significant because during this time windmills were used along the
coast of china for wind power
Some windmills are still intact in Iran
and Afghanistan from the 7th century
These windmills are reverse of the windmills today
however, wind energy went into a chamber to turn
blades, while today the blades are on an external axis
The y are still around today and can grind about a ton
of grain per day
5. ELECTRIFICATION
Until the late nineteenth century windmills
would only produce mechanical power for
their tasks such as grinding grain or pumping
water.
With the creation of electricity, windmill
makers found that windmills could be attached
to a generator and used to create power for
heating and lighting.
The first windmill used to produce electric
energy was created in 1888 by Charles F.
Brush.
These windmills needed to produce 500
revolution per minute in order to power a
generator.

7. Wind is Free, and the power it generates has
been harnessed for centuries
Wind is a completely renewable resource
because it is something that occurs
naturally, once the means are there;
technologically and practically, it can be
harnessed constantly without destructive
effects (emissions and use of resources) to
our abused planet.
Generation and maintenance costs for
turbines have decreased significantly in
recent years
Wind power is well suited to rural areas
PROS OF WIND ENERGY
8. CONS OF WIND
There are many obstacles to optimal use of
Wind Power
Transmission- How to get energy from point A to point B
Technology- Means storage and containment of power
must be developed
Weather- Wind power is highly subjective not only
to location but also to climate, time of year, and
currents/weather patterns
For many problems new tower designs
provide an answer
Noise and view disruption become an issue with
communities near wind farms
Endangered birds can be killed by flying too close
to wind turbines
9. HOW WIND ENERGY AFFECTS US TODAY
As of today wind energy is best fit to be used
as an alternative source of energy but as
costs go down and effectiveness goes up this
could soon change, and wind energy may
become a viable option the leading source
powering the future. Placement is key in using
wind farms and windmills, because if the
money is to be spent to create one, optimal
effectiveness will need to be assured.
