Minister of Planning and Development Ahsan Iqbal recently informed the parliamentary committee on CPEC that Thar coal would be used for electricity for the next 400 years and that two transmission lines were being installed at Mariari — one to Lahore, and another to Faisalabad, which will be connected to the national grid, benefiting all parts of the country. He also stated that some 11,000 MW of electricity will be added to the national grid by 2018 with the help of the biggest energy investment in the history of Pakistan under CPEC. It will be great news if Pakistan can get rid of power outages in major cities.

But the bad news is that over 8,000 MW of this energy will come from coal — major source of carbon emissions in China itself. What consequences will the coal-fired plants, particularly in central Punjab have, usually enveloped by smog in December? China, which surpassed the US in carbon dioxide emission in 2007 becoming leader in world pollution, is already reeling from the impact of the coal energy. In 2014, for instance, Chinese scientists compared the toxic haze to a “nuclear winter” that “has started slowing down photosynthesis in plants.”

And recently in December 2016, environmental protection officials called on the government to issue red smog alerts for 23 cities in northern China. Beijing officials had already issued a red alert after warnings of a build-up of toxic air pollution during cold weather. An additional nine industrial cities had also been advised to issue the lowest-level orange alert. In fact, images of school children taking exam in an open football stadium enveloped in a dense cloud of noxious pollution, which triggered the smog “red alert” on December 20, went viral on the social media.

Taking cognisance of the choking smog, Chinese officials began taking its environmental problems seriously in the year 2014. They struck a deal with the US to reduce the rate of its carbon emissions by 2030. Statistics from the Chinese National Bureau of Statistics show slight reduction in coal consumption (to 3.7 per cent and 2.9 per cent in 2015 and 2014, respectively). But obviously it has to go a long way because 70 per cent of the China’s electric power comes from burning coal and the consumption is estimated to be nearly as much as rest of the world combined.

The thoughtless rush for coal-fired energy by a politically motivated Pakistani ruling elite is both alarming and questionable. Minister Ahsan Iqbal and other leading lights from Punjab know what havoc the fog and smog play with life in winter. They also know unscrupulous nature of the mighty business cartels behind the energy plants. Those running and approving these cartels — politicians, businessmen and bureaucrats, are least bothered about the environmental hazards of coal energy in a country where bribes cover up violations of law.

Most of these businessmen and their political patrons, with second permanent residences and interests parked in the US, Canada and Europe, seem to ignore the havoc coal energy has played in China. For them the overriding motive of importing mostly second and third generation coal-fired plants appears to be quick hefty windfalls.

And let us not blame China for the cunning attitude of our rulers and businessmen. If we go by what Ahsan Iqbal told the parliamentary committee on January 16, it suggests that Beijing has been sensitive to, and adjusting, the CPEC plans to the demands by K-P and Balochistan. They have been facilitating Pakistani wish list as and when necessary following the discord between Islamabad, Peshawar and Quetta.

Most of Pakistan’s big cities such as Karachi, Faisalabad, Multan, Gujrat, Gujranwala, Peshawar and Quetta are already air-water polluted. With the induction of coal energy, and little hope for adherence to environmental standards, this situation will deteriorate. And responsibility for this disaster in the making will rest on Asif Ali Zardari as well as the Sharif brothers, ably supported by a pliant bureaucracy and avaricious business community.

What ever be the case, Coal has been instrumental in rise of Europe, America and China...numerous technologies now make coal cleaner..one way to get clean energy out of coal is to gassify it..while everyone one is busy bashing coal fired power plant..they tend to forget that coal provides a very important building material ..fly ash...without which we will not have very strong concrete and light weight bricks..coal may be bad..but it is needed in moderation..

Unfortunately they never faced the same environmental threats Pakistan does. Major cities are already largely polluted from motor vehicles from the 1960's.

Will we glassily coal?

Every energy source has its pros and cons. It is up to Pakistan to decide what mix of energy sources it wishes, or is able to, use to alleviate its chronic and growing power shortages. Coal very likely will need to be part of the solution.

We should get gas from iran!

Plants being installed are new generation.. emissions are treated before release..
We are currently running plants on petrol which is far more expensive and unsustainable...

Thar coal has more energy (in coal form) than saudi arabian oil reserves (in form of oil) ... there is absolutely no question that we are going to use coal.... we need to improve technology as we go...

And no one better than china to partner in that... as they have biggest experience in utilizing coal

Coal has killed the environment in China. There is a reason why countries are turning away from it.

Coal can be converted into liquid fuels or gas those can be used for power generation. Gasification is a safe and clean process using coal of any grade and byproducts can be purified.
So arugment of pollution doesnt hold 2 cents value.

Is that what pakistan will be doing?

one will say Chinese coal Power Plants are of old technology. CPEC projects will be of new technology which will decrease negative impact on environment. but here China is canceling "new projects" , some even completed. i am not against using coal neither am i criticizing china. i am just posting a news.



China’s war on coal continues — the country just canceled 104 new coal plants

Because China is such a behemoth, its energy decisions absolutely dwarf anything any other country is doing right now. Case in point: Over the weekend, the Chinese government ordered 13 provinces to cancel 104 coal-fired projects in development, amounting to a whopping 120 gigawatts of capacity in all.

To put that in perspective, the United States has about 305 gigawatts of coal capacitytotal. The projects that China just ordered halted are equal in size to one-third of the US coal fleet. If the provinces follow through, it’s a very, very big deal for efforts to fight climate change.

This move also shouldn’t come as a big surprise. In recent years, China, the world’s largest emitter of carbon dioxide, has been making major efforts to restrain its coal use and shift to cleaner sources of energy. When Donald Trump and other conservatives in the United States complain that China isn’t doing anything about climate change, they simply haven’t been paying attention.

China’s coal use is falling — and this may be a lasting shift
Back in 2013, China was using as much coal as the rest of the world combined, and it looked like coal use would keep growing astronomically forever. Local officials were planning hundreds of new coal plants as demand looked like it would keep soaring for decades.


Except then an odd thing happened. Since 2013, China’s coal consumption has actuallyfallen — due in part to a major economic slowdown but also in part to sluggish output in heavy industries like steel and cement that have traditionally accounted for half the country’s coal use. (The usual caveats about China’s murky energy statistics apply.)

Increasingly, many analysts suspect that this slowdown in coal consumption is a lasting shift — particularly as China transitions away from heavy industry and investment-driven growth and into a modern service-oriented economy that’s far less carbon-intensive. Going forward, China’s economy is expected to be focused more on retail shops and hospitals, less on steel and cement plants. Energy demand will slow.

On top of that, as China’s leaders start to take global warming seriously, the country has been making massive investments in clean energy. As part of the Paris climate deal, China has pledged to get 20 percent of its energy from low-carbon sources by 2030. The government is planning to install an addition 130 gigawatts of wind and solar by 2020 and making big bets on nuclear power. Some analysts suspect this growth in clean energy could be sufficient to satisfy much of the future growth in household electricity demand.


When you add those two trends together, many forecasters think China’s coal growth will either flatline or fall in the years ahead. One recent paper in Nature Geoscience predicted that China’s coal consumption may have already peaked in 2013. And if that’s true, then many of the hundreds of coal projects that China has on the drawing board will be flatly unnecessary.

China is now putting a hard limit on coal capacity — but there’s a catch
So that brings us to the recent cancellations. China currently has around 920 gigawatts of installed coal capacity — and many of those plants are already running at lower-than-expected capacity because of weak demand. But there are also hundreds of new coal plants in various phases of planning around the country that would bring total coal capacity nationwide up to 1,250 gigawatts.

That seems excessive, given recent trends. So in China’s latest five-year plan, Chinese officials put a hard cap on future coal capacity at 1,100 gigawatts. Then last week, they ordered provinces to cancel 104 coal projects in the works that were worth an estimated $30 billion. Of those, 47 projects were already under construction, according to a Greenpeace analysis.

Lauri Myllyvirta, an analyst at Greenpeace who has been following this story closely for years, made a map of the plants targeted for cancellation:

That said, there are a whole bunch of important asterisks here. First, Beijing has only ordered the provinces to cancel the plants. The provincial governments still have to actually comply. (And we’ve seen some provinces defy Beijing on overcapacity cuts before.)

Second, even under the new cap, Chinese coal capacity still has some room to expand going forward — which is why environmental groups like Greenpeace are calling on the government to go even further and cancel the rest of the dozens of new coal projects still in various stages of planning.

Third, while any slowdown in Chinese coal demand is good news for climate change, it’s not great news for climate change. If the world wants to avoid drastic global warming — typically defined as 2°C or more — then it’s not enough for China’s CO2 emissions to simply plateau. They have to fall, very drastically. Doing that will require more than simply canceling any future coal plants. It will mean either retiring existing coal plants and replacing them with cleaner sources (as the United States is currently doing) or retrofitting the plants with carbon capture technology and burying their emissions underground.

Finally, there’s an important political angle here. China’s struggle to curtail coal use is putting thousands and thousands of miners out of work, and if it moves too fast, it risks unrest in key coal-producing regions (something US politicians are familiar with). Last year, Prime Minister Li Keqiang announced the central government would need to set aside $15.3 billion for areas ravaged by unemployment. He also promised that future job growth in other sectors would help absorb losses in the declining coal and steel sectors. But no one knows if China can pull off this tightrope act.

Which is all to say that this week’s big coal plant cancellation is just one (important) chapter in a story that’s going to unfold over many decades, with plenty of twists and reversals still to come.

Nothing is cheaper, dependable and above all more reliable than local reserves be it coal or gas!
Buying gas form Iran cost money...and in this case..hard forex...
 
.
Gas, in its many forms and sources, will also need to be an important part of the solution.
 
.
Is that what pakistan will be doing?
Suna tha Dr. Samarmand Mubarik ne Thar main process shuru kiya tha-- Much money was needed for a water pipeline but he didnt get further finances by GOP and sari mehnat bekar gai. :lol:

No country in world is coal free... may be gulf states with seas of oil... uk us france germany whole europe uses coal to some degree...

We happen to have largest un tapped reserve in world... what shud we fo with thar coal??
