This document discusses wind turbines and wind farms. It begins by explaining what wind is and the basic types of wind turbines, including horizontal axis and vertical axis turbines. It then discusses the major components of modern horizontal axis wind turbines. The document provides information on the top 10 wind power companies worldwide and lists the largest wind power plants, including the Alta Wind Energy Center in California, USA. It also discusses advantages and disadvantages of wind energy, as well as potential wind energy sites in the Philippines, including the Bangui Wind Farm in Ilocos Norte.

2. What is wind?
Wind is simply air in motion. It is
caused by the uneven heating of
the earth’s surface by radiant
energy from the sun.

3. WindTurbine
A wind turbine is a device
that converts kinetic energy from
the wind into mechanical energy.

4. BasicTypes(Turbine)
• Horizontal Axis Wind Turbine
(HAWT)
• Vertical Axis Wind Turbine (VAWT)

5. VerticalAxis WindTurbine
Subtypes:
• Darrieus Wind Turbine
• Giromill
• Savonius Wind Turbine
• Twisted Savonius

10. Wind power plants, or wind farms, are
clusters of wind turbines used to produce
electricity. A wind farm usually has dozens
of wind turbines scattered over a large
area.
Choosing the location of a wind farm is
known as siting a wind farm. The wind
speed and direction must be studied to
determine where to put the turbines. As a
rule, wind speed increases with height, as
well as over open areas with no
windbreaks.

11. TypesofWindFarm
• Onshore Wind Farm
Onshore turbine installations in
hilly or mountainous regions tend to be on
ridgelines generally three kilometers or
more inland from the nearest shoreline.
• Offshore Wind Farm
Offshore wind power refers to
the construction of wind farms in bodies of
water to generate electricity from wind.

Bangui Wind Farm
The town of Bangui in
Ilocos Norte is one of the few
shining examples in the region that
wind power could be used to
provide affordable and clean
energy for a vast chunk of a
province’s population and
industry.
