“ The Contribution of Wind Energy in
the Energy Mix of the World”

The fastest growing industry of the world today is
the Wind Energy. It had grown at a compound
rate of 23.6% for last 10 years. No industry in
the history has grown at this rate. Various
agencies have projected the demand by using
various methods.

The wind sector became a global job generator
and has created 6,70,000 jobs worldwide.

The wind sector represented in 2010 a turnover of
40 billion €.

CURRENT OPERATING COSTS

Though Wind Energy is a capital intensive proposition,
you will see from the figure, the operating cost of wind is
lower than any other method. Sometimes people think
that nuclear is cheaper, but that is not the case. On the
contrary, these figures regarding the operating cost of
nuclear system will be much higher than shown here
since the price of uranium also has skyrocketed like the
oil price. While the only steady operating cost is wind
since there is no raw material cost.

The Massachusetts Institute of Technology (MIT) has
predicted that the world electrical energy requirement will
triple by 2050. The current electrical energy installation is
around 3.6 million MW, which will become about 11 million
MW. It is unthinkable to imagine this much quantity being
produced by fossil fuel. What will happen to the green
house gases (including carbon dioxide concentration) is no
more a guess work. It will make the world unsuitable for
life. We can keep these figures lower only by adopting
18th century life style. But this is not possible. If China
and India start consuming per capita electrical energy, as
much as what the US consumes, the figures are
unbelievably large.


The realization through out the world has come that this
Earth does not belongs to the present generation; it belongs
to our children and we have borrowed it from them. It is our
sacred duty that we return the earth in a better shape to our
children than what we have received from our forefathers.

The fossil fuels are finite and we must use them very
judiciously instead of burning them off for generation of
electrical energy. We must preserve them for high value
added petrochemicals and other important materials. The
basic definition of economics tells us “Economics is the
science which deals with ends and scarce means which have
alternate uses”. The fossil fuels are scarce and they have
better alternate uses than burning them off for energy.


Another important thing which normally people do not
realize is that with increase in the population of the
world, the demand for food grains is also increasing.
Consequently the demand for chemical fertilizers is
also increasing. All the chemical fertilizers, through
out the world, are produced by burning fossil fuels. If
we exhaust fossil fuel for energy, how are we going to
meet the increasing food demand for the inflating
population? We will have to resort to natural organic
fertilizers and preserve fossil fuels.
The recent studies carried out by the California Energy
Commission (CEC) mandated with the task of
periodically examining the cost of various electricity
generation technologies have clearly indicated that
most renewable technologies, even solar photovoltaic,
will be able to generate electricity at a lower price than
the nuclear power in 2018.


IOU – Investor-Owned Utility POU – Publicly-Owned Utility

Is the renewable energy capable of meeting
this incredible demand of electrical energy?
Intensive researches are going on in photovoltaic and its related
fields. The prices of PV cells are slowly dropping, but still they are
quite far from commercial viability without governmental supports.
It may become possible to economically produce large scale
electrical energy by PV within 45 years.

The tidal energy has limitations. You need a particular geographic
condition to have a tidal power plant. The only sizeable power
plant working in France is at a place called La Rance. It produces
240 MW for more than 40 years very successfully. It is estimated
that around 200,000 MW can be generated from various places
known to have a conducive situation for tidal energy production
around the world. The Government of Gujarat in India has
embarked upon an ambitious project called “Kalpasar” where 5800
MW of electrical energy will be produced by tidal power.

The study concludes that if only the areas having an annual
average wind velocity grater than 7 m/se are taken into
account, wind worldwide could produce approximately 72
trillion watt hours of electrical energy per year. This is equal
to about 54,000 million tones of oil equivalent. Even if only
20% of this power is captured, it is more than the total
energy requirement of the entire world for all purposes. If
we consider just the electrical energy requirement of the
entire world, this potential is seven times the world needs,
which is 1.6 to 1.8 Trillion Watt hours.

If we take into consideration areas which have got lesser
than 7m/sec wind velocity, and the offshore potential, the
figure will be astronomical.


While looking at the World map for the potential of wind energy, it
is clear that very large land mass of the earth fall under
uneconomical zone, having inadequate wind velocity for economic
electricity production.

Necessity is the mother of invention. People around the world are
working on designs which can produce electricity economically
even in these zones. Some such ideas are discussed here. They
are;

• Air Rotor System – Magenn
• Wind Mills in the Sky (Autogyro) - USA
• Wind Energy Marine Unit (WEMU) Being Developed in Russia
• Ladder Mill (Kiteplanes) - Denmark
• Multi-Rotor Shaft
• Vertical Axis Turbine
• Maglev Wind Turbine
• Linear Motor Frame
• Dual Rotor Design - Korea
• Wind Lens Turbine

Air Rotor System - Magenn


Wind Mills in the Sky
(Autogyro) - USA

Groups working in the US, Netherlands and Canada are readying to set up wind farms 9
kilometers up in the sky. This is where we have the so called jet stream, or corridors of high
velocity winds, which high altitude aircraft make use of while flying eastwards.

Additional aspects needing attention

- To overcome fluctuation in wind power production on daily
as well as seasonal basis, large quantity of electrical energy
storage has become necessity. Considerable success has
been reported.

- It is necessary to make production of small wind turbines in
mass so that the current exorbitant prices can be brought
down to affordable levels If this happens, it is anticipated
that every roof top will have a small wind turbine/PV hybrid
system to meet domestic electrical demands. This is also a
very big portion of electrical consumption.


Recent developments have made it possible to store large
scale, MW hours, electrical energy. This will enable

a) Storing energy in off peak time and supply during
peak demand periods.

b) Smooth load and grid stability control.

c) Frequency and voltage fluctuation control.

d) Grid reinforcement.

In conclusion, the wind energy is
progressing very well and is going
definitely to come to the rescue of
the mankind. In my opinion, this is
the only source, which is in
abundance and can be economically
exploited without disturbing the
balance of nature.
