1.High annual average wind speed:
2. Availability of anemometry data:
3. Wind structure at the proposed site:
4. Altitude of the proposed site:
5. Distance to road or railways:
6. Nearness of site to local centre/users:
7. Nature of ground:
8. Land Cost
9. Availability of labors & Material

4. Introduction to Wind Energy
 Wind energy is actually a
byproduct of the sun. The
sun’s uneven heating of the
atmosphere, the earth’s
irregular surfaces (mountains
and valleys), and the planet's
revolution around the sun all
combine to create wind.
 Since wind is in plentiful
supply, it’s a sustainable
resource for as long as the
sun’s rays heat the planet.
 Wind energy is having
basically Kinetic energy

7. Advantages of WECS
a. It is one of the lowest-cost renewable energy technologies that
exist today.
b. It is available as a domestic source of energy in many countries
worldwide and not restricted to only a few countries, as in the
case of oil.
c. It is energized by naturally flowing wind
d.Thus, it is a clean source of energy. It does not pollute the air
and cause acid rain or greenhouse gases.
d. It can also be built on farms or ranches and hence can provide
the economy in rural areas using only a small fraction of the land.

8. Disadvantages of WECS
a.The main challenge to using wind as a source of power
is that the wind is intermittent and it does not always blow
when electricity is needed.
b. Higher initial investment
c. It may have to compete with other uses for the land,
and those alternative uses may be more highly valued
than electricity generation.
d. It is often that good sites are located in remote locations,
far from cities where electricity is needed.
e. There may be some concerns over the noise generated
by the rotor blades and aesthetic problems that can be
minimized through technological developments or by
correctly siting wind plants
