Wind-Power: The solution to our energy crisis

By -

In the current energy crisis that we are facing today; it is imperative to look for alternate energy resources. Our world’s coal, oil and gas reserves are finite and will eventually be exhausted whether it  is 50 years, a century or a couple of centuries.

Pakistan has tremendous potential to develop hydro –power, but along with scarce monetary resources our Government also lacks a will to take the bold initiatives to get us out of this energy crisis. Solar panels are being used in some parts of the Country but a mega-power project on the basis of solar energy is high in cost and certainly not feasible for a poor country like Pakistan.

Wind Farms Texas/US

Wind power is perhaps the best solution to Pakistan’s problems.

What is wind power?

Wind power generation is the process to harness the kinetic energy of the wind gusts and turn it into useful electrical energy. It is by far less in cost, and if handled properly it could server as the ultimate life-saver for an energy deficient country like Pakistan.

How it is done? A wind turbine is  installed in an area with considerable wind activity (wind turbines usually start generating power at wind speed of greater than 9 mile/hr). The rotors of the turbines are moved with the kinetic energy carried by the wind. The rotors then turn a shaft connected to a turbine and electricity is generated.

The advantages of wind power are numerous. They are considerably less expensive to install than solar panels.  They are Eco-friendly meaning that they burn no fuel and hence emit no harmful gases. A large commercial  wind-turbine can power 1000 houses!!!

Wind turbines can work on individual basis, this is ideal for end-users. For example remote villages or isolated places can use this technique to high effect.

Lying 150 kilometers (94 miles) due south of Pakistan’s financial capital Karachi, Kharochhan is an island of thatched homes where fishermen scrape by on 75 dollars a month and never dreamed of having electricity.

Then a local charity pitched up and installed five wind turbines. Now a fifth of homes — 100 out of around 500 — have been hooked up to the system.

“Each of us saves up to 1,500 rupees (18 dollars) that we would have spent on kerosene. I couldn’t afford to educate my children, but now I’ll put two of my four daughters in school,” Arif said.

“We’re poor with meager resources. Our boys usually become fishermen and our girls illiterate housewives. This money could help us improve our children’  future,” he added. (source)

On a larger scale, wind-farms can be used as a mega project for power generation. Denmark and even our neighbor  India are beautiful examples.

The need is to see the problem as a problem with a solution; we are the ones who will solve our problems not someone from outside. It is high time to initiate alternate energy projects in transparent ways so that monetary assistance from sources like Asian Development Bank, World Bank, Private investors can be obtained.

  1. I recently visited the coastal belt along Karachi. Believe me, the wind there is ideal for harnessing wind energy. And as engineers, why should we wait for someone, especially our govt to take a step? We can become entreprenuers and start doing this initially on a small scale and then expanding later on.

    Btw the Paki govt recently signed a MOU with the Chinese govt for wind and solar farms. Lets see what happens regarding that.

    very well writen article, i agree wid the fact that wind energy can bring great change to solve energy crisis in our country.

  3. To be honest, Pakistan actually does not need alternate energy. We have some 30,000MW capacity of hydro power why look for something expensive,inconsistent ? There is no such crisis of energy in Pakistan, it has been result of mismanagement and absence of long term planning. Build more dams, cant think of any greener and efficient power production process

  4. i agree with faisal too, but i dont think the current govt is much capable of doing such stuff at least nowadays, seeing their own problems…

  5. @faisal

    no doubt pakistan has enought potential in hydro-power sector but it is a much controversial issue. Wind energy is cheaper than building new dams, besides dams require ideal location considering climate, height, topography. Wind energy on the other hand has less requirements, we did a small research on this and we found that more than 60% of pakistan has areas where wind-energy projects can be started on mega scale.

    Whatever the method, it remains the responsibilty of the people and the government to handle and exploit it properly.

  6. @hassan

    can you please tell the source for the fact that 60% of pakistan is faesible for energy generation through wind power.

  7. @hassan

    its not a fact, it was the conclusion of a small private research

    see wind roses for pakistan,or come to my house I will show you the 'research reports'.

  8. @ faisal & all those who agree: I hate to burst your bubble but, dams aint green. Infact, they are an "environmental disaster"!! Shocked, eh? I am doing Environmental engg from IESE, NUST and we have learned that if we have enough land to waste or have absolutely no other alternatives (are too lazy to try wind or bio), only then the constructed dams should be an option.

    Man made water reservoirs are a scar to Earth's already wounded face because they cause:

    a)Fragmentation of river ecosystems

    b)Reservoir sedimentation

    c)Riverline and coastal erosion

  9. dams may be bad for some cases..but no prosperous country has been born without being "damed", they have looked forth to wind, solar etc after they had their surplus electricity generation, even if wind is preferred, who is going to allow its setup>? in balochistan the people there dont allow it as it is their land, elsewhere there are similar problems…

  10. dude, can u think of a set of people who have actually welcomed the government's decision of constructing land on their land? well, would u be happy? Dams/reservoirs require the relocation of large amount of human populations, clearing of forest area, destruction of river ecosystem, which in turn, affects the livelihood of people doing fishing as their sole source of income. Plus, a dam's average lifespan is about 50 yrs (in USA). The largest dam in the world, the Tarbela dam, has a life span of maximum 85 yrs (till 2060). What will we do with such large structures of concrete after it has all silted up?

    Sure we need water reservoirs for the collection and storage of water via rainwater harvesting, but they are not dams. Their hydrolics is entirely different (they do not block a river). Besides, I'd really like to know which country likes to produce "surplus" energy after its needs are already met :p

  11. i didnt meant to go into a big argument, but i guess every thing has its own pros and cons 😛

    as for exporting surplus energy..i think canada is 1st…it exports about 31% of its energy production…

    http://www.itintl.com/canadian-energy-exports.htm

    plus the construction of a dam would mean more opportunities for NUST engineers..:P, but , obviously at the cost of the things you mentioned above

  12. oh, so thats whats its really about 🙂 well, from what I have learned, a number of 32 new dams has been chalked out. Go to http://www.nation.com.pk/pakistan-news-newspaper-…. Thus, u cant really complain :p

    Btw, almost all energy generation units need engineers of all sorts, whether it be the design or the functional phase. Nustains wont go out of business as long as they know how to apply that knowledge & be innovative.
