Potential and Outlook of Wind PowerÂ
Global wind power is now two times over last
three years. Wind power produces 2 percentages of world electricity production.
Survey shows that 13 percentages of world land areas have wind speed more than
6.9 m/s at a height equal to commercial wind turbine height and if we calculate
we came to know that wind power unit can produce forty times  of
world current electricity production.Â
There are some countries those are
consider as leader in wind power production such as mentioned here.
- Denmark
- Germany
- Spain
Also discuss Application of Solar Energy
In current condition,
there are 68000 operational wind turbines.
In case of United
States, in 2006, there are wind turbines those produces power 9000 MW or 25
billion KWh electricity .let’s see the power production in US in 2005
- Coal = 5.2 %
- Nuclear = 20 %
- Natural gas = 16 %
- Hydro power = 7%
- Wind power production + Solar power production  + Geothermal power production+ Biomass power production = 5%
Ten largest wind firms in US
- Alta wind energy center = 1020 MW
- Shepherds flat wind farm=845 MW
- Roscoe wind farm= 781 MW
- Horse hollow wind energy center= 736 MW
- Tehachapi pass wind farm = 705 MW
- Capricorn ridge wind farm=662 MW
- San gorgonian pass wind farm=619 MW
- Fowler ridge wind farm=600 MW
- Sweet water wind farm=585 MW
- Altamont pass wind farm=576 MWÂ
Comparison between wind power versus fossil fuels
A.   Cost
point of view
Here we can see the cost
difference between wind power and fossil fuels
- Wind energy is less expansive as compared to fossil fuel
- In case of fossil fuel, the price of electricity will fluctuate greatly because there is variation in transportation cost and variable mining.
In case of wind power ,cost
of wind is fixed and free.
B.   Emission

C. If we compare wind
energy as compared to other source of electricity production, Wind energy will
provide 30 % more employment as compared to coal plant per unit of energy
generated. Wind energy will provide 66 % more employment as compared to Nuclear
power plant per unit of energy generated.
D.   Wind
energy protects the water resources
E.   Wind
energy does not promote to global warming, while fossil fuel burning lead to
heating of earth and hence lead to global warming.
F.    Wind
power unit also protect land.
G.   Wind
power unit help to avoid the excessive use of fossil fuel and hence it can
reduce the price of fossil fuels ,so we can consider it as social advantage
point.

|
During
erection ,wind power unit requires larger equipment and more consideration of
safety as compared to solar power unit
|
Solar
power unit installation is very easy and not require heavy equipments
|
7
|
Requires
good density and speed of air
|
Requires
good exposure of sunlight
|
8
|
Wind
power unit can produce power day and night 24 hrs where wind is blowing
sufficiently
It’s
does not depend on winter season and rainy season
|
Solar
power can produce only In day time as it requires sunlight.
Performance
of solar power unit will be poor in rainy season and winter season
|

|
Wind
power unit installation is low as compared to solar power unit installation
|
Solar
panels are costly

Wind
power is not suitable for every location as suitable resources will not be
available everywhere
|
Can
be used almost everywhere
