The financing model underpinning the US shale oil industry is fundamentally different from that of large companies producing predominantly in conventional oil. Small and medium-size independent producers, which dominate the US shale industry, generally have much higher leverage with high levels of debt and hedging. Since its inception, the industry has been characterised by negative free cash flow as expectations of rising production and cost improvements led to continuous overspending in the sector. Over the last few months, the industry as a whole has seen a notable improvement in financial conditions, though the picture varies markedly by company, and the overall health of the industry remains fragile.
In order to try to assess as precisely as possible the developments of shale industry throughout the decade, we identified four distinct phases that have characterised the shale industry since 2010 up to now.
2010-14: The start-up phase
In the 2010-14 period, technology developments and high and stable oil prices triggered a massive investment wave in the US shale sector. Investment more than quadrupled, leading to an eightfold increase in shale oil production, from 0.44 million barrels per day (mb/d) to over 3.6 mb/d – the fastest growth in oil production in a single country since the development of Saudi Arabia’s super-giant oilfields in the 1960s.
However, the growth came with a huge bill. The sector as a whole generated cumulative negative free cash flow of over USD 200 billion over those five years. Throughout this phase, companies were forced to rely extensively on external sources of financing, predominantly debt and receipts from the sale of non-core assets, in order to finance their operations. In addition to issuing bonds, companies benefited from the reserve base lending structure – a bank-syndicated revolving credit facility secured by the companies’ oil and gas reserves as collateral. This structure was used heavily by small and medium-sized companies with non-investment credit rating that did not have as easy access to the corporate bond market.
2015‑16: The survival phase
The collapse of prices in the second half of 2014 and throughout 2015 and early 2016 had a major impact on the way the shale industry operates. Companies switched to survival mode, focusing on improving efficiency and cutting costs. The number of firms declaring bankruptcy and filling for Chapter 11 protection, a form of bankruptcy involving reorganisation, skyrocketed to almost 100 in 2015-16.
The fall in prices also changed the way the shale industry was financed. Debt finance dried up as banks were unwilling to lend during a period of market turmoil, with bond yield spreads widening to over 1 000 basis points and the credit rating of the majority of companies being downgraded. Asset sales also dropped by 70% in 2015 as owners were unwilling to part with assets at the much lower prices on offer. While the main buyers of the assets were US independent companies, the market turmoil discouraged bank lending, opening up opportunities for financial firms such as private equity firms, which typically have a higher risk profile. Those firms accounted for around 30% of reported asset deals over 2015-16. Available funding from the reserve base lending structure also declined as the value of proved reserves for collateral shrank with lower oil prices. The net result was that companies were obliged to raise equity to finance their operations – a more expensive option.
Despite the slump in revenues throughout this period, the shale industry actually saw an improvement in free cash flow as a result of huge cuts in capital spending and costs. Between 2014 and 2016, investment fell by 70% and costs by around half. Cost reductions helped to offset the impact of less investment, such that shale oil production declined only modestly in 2016.
2017: The consolidation phase
The recovery of oil prices since mid-2016 following the collective decision by the Organization of the Petroleum Exporting Countries (OPEC) and some non-OPEC producers to cut output led to a revival in confidence in the US shale sector. Further advances in technology, huge efficiency gains and cost reductions, and an upward revision of the shale resource base triggered an increase of 60% in investment in 2017. In the meantime, the shale industry proved that its upstream cost structure had been rebased as it was able to offset inflationary pressures coming from overheating of the supply chain, further reducing the overall costs per barrel produced.
Despite the improvements achieved, however, the shale sector continued to slightly over-spend the cash flow generated from its operations, with 2017 cumulative free cash flow remaining overall negative. Asset sales once again became the main source of financing operations, with most transactions occurring between US independent companies. Asset sales involved mainly acreage rather than whole companies, as companies sought to do relatively small deals as a way of making gains in operational efficiency. The confidence in the shale sector, traditionally dominated by private investors and small and medium-sized companies, received a boost from announcements by large US oil companies of their intention to make substantial investments.
2018: Profitability at last?
Current trends suggest that the shale industry as a whole may finally turn a profit in 2018, although downside risks remain. Thanks to a 60% increase in investment in 2017 and, based on company plans, an estimated 20% increase in 2018, production is projected to grow by a record 1.3 mb/d to over 5.7 mb/d this year. Several companies expect positive free cash flow based on an assumed oil price well below the levels seen so far in 2018 and there are clear indications that bond markets and banks are taking a more positive attitude to the sector, following encouraging financial results for the first quarter. On this basis, this we estimate that the shale sector as a whole is on track to achieve, for the first time in its history, positive free cash flow in 2018. This result is all the more impressive given the context of rising investment.
Structural changes also augur well for the sector. Recent consolidation, such as the recent USD 9.5 billion Concho-RSP Permian merger, and the increased participation of the majors and other international companies could bring significant economies of scale and accelerate technology developments, including through digitalization. Larger companies generally have a more robust financial structure and rely less on external sources of financing, so their shale investment will be less vulnerable to future downswings in oil prices and financial conditions.
The potential risks for shale independent from rising interest rates are currently attracting a lot of attention. The impact of rising interest rates on independent oil and gas companies in the US shale industry may also be small. Most companies are highly leveraged, benefiting from the ample availability of low-cost bond finance. However, given the high depletion rate, the time horizon of shale projects is so low that the discount rate has only a minor impact on the net present value of a given project. Rising interest rates often coincide with tighter lending conditions, which may make it harder for companies to service their debts and refinance their operations. But this risk can be managed through asset sales to less-capital-constrained companies, such as the majors, and increased reliance on equity raising through IPOs and private equity.
A lot of attention has been focused on interest expenses – the cost of repaying debt. The development of shale production has been accompanied by constantly rising interest expenses, which has impeded companies from generating profits sustainably. For the first time, the overall amount of interest expenses paid by shale companies declined in 2017. While US shale companies remain far more leveraged (measured by the net debt/equity ratio) than traditional operators, leverage is falling from its peak in 2015 and the average interest rate paid by shale companies – currently around 6% – has been broadly stable in recent years despite rising interest rates generally since the end of 2015, though they still pay more than conventional oil producers. Improving financial conditions mean that shale companies are able to borrow more cheaply than before.
The US shale industry seems to have reached a turning point with the recent significant improvement in its financial sustainability. But major uncertainties and important downside risks to the future of the shale industry remain:
Above-ground constraints: With production rising very rapidly in certain basins, such as the Permian, timely investment in takeaway capacity and pipeline infrastructure will be vital to the further expansion of the industry. At present, several producers in the Permian Basin are forced to discount their crude oil by more than USD 15 per barrel compared with the price on the Gulf Coast due to a lack of pipeline capacity. No significant pipeline capacity expansion is expected before 2019. The importance of infrastructure applies not only to oil but also to associated gas production, wastewater and other products. In the absence of new pipeline capacity, companies might be forced to curb drilling or ship their production using trucks or rail, which are usually much more expensive.
Further productivity gains: The continued ability of the companies to offset inflationary pressures with improved productivity stemming from technology or improved project execution remains very uncertain. In most active basins, especially the Permian, there are clear signs of overheating and bottlenecks in skilled labour, materials and equipment. In addition to the potential for further technological advances, there may be scope for more efficiency gains, for instance by expanding operations in continuous acreages, improved understanding of the resource base and more accurate spacing of wells.
Grabbing the fruits of the “digital revolution”: Companies are putting more effort into developing and adopting innovative digital technologies and big-data analytics in order to reduce costs, by optimising operations, improving reservoir modelling and enhancing processes.
Competition from other sources of oil: The US shale sector has not been alone in reducing its costs and will need to continue to do so to remain competitive in international markets. Most onshore resources, especially in OPEC countries, cost less to produce than shale oil, while the bulk of new deepwater projects are competitive with the cheapest shale basins. Consequently, the US shale industry is required to keep improving.

CPEC: The not so cool COAL corridor
With energy comes wealth and with wealth comes prosperity! No one can doubt the veracity of this conclusion. But most of the times we forget to scrutinize the “energy” which generates that wealth and societal well-being. For a developing nation state like Pakistan, good infrastructure and plentiful energy are very necessary ingredients to grow and stabilize its economy. A friend in need is a friend indeed. China, the all time friend of Pakistan, showed the act of friendship in April 2015, when President Xi Jinping visited the country to oversee the signing of agreements aimed at building $46 billion (now worth $62 billion) China Pakistan Economic Corridor (CPEC) as a part of his One Belt One Road initiative between Pakistan’s Gwadar Port on Arabian Sea and China’s western region of Xinjiang. This multibillion-dollars project is intended to develop Pakistan’s infrastructure, transportation and very importantly will help the country alleviate chronic energy crisis. The mega project has been declared “a game changer” for Pakistan by its government, but I think that it has been failed in properly analyzing the costs and benefits of the project. There isn’t only a huge monetary cost associated with the economic corridor which Pakistan will bear- as it has to pay back the principal amount of loan with interest, that China is providing her in the name of CPEC, but will also incur hefty environmental cost .
A big portion of total cost of CPEC, nearly $33 billion will be invested in the energy sector of the country. Pakistan’s average demand of electricity (according to the International Energy Agency) is around 19000 MW, while its generation capacity is around 15000 MW, that is, a total energy deficit of 4000 MW. According to IEA’s prediction, by 2025 Pakistan’s per day average electricity demand would reach as high as 45000 MW. To help Pakistan getting out of this serious energy crisis, the multi-billion-dollar economic corridor has numerous power plant projects. Most of the energy which will be generated under CPEC will be from coal fired power plants. $5.6 billion worth of coal power projects are expected to be completed by 2019 in CPEC’s “Early Harvest” projects, but what about the environment?
There are certain compounds (mainly in the form of gas) which trap heat energy in the earth’s atmosphere, keeping the earth’s surface warmer than it would be if they were not present. Such compounds are termed as greenhouse gases. Ability of these compounds to trap heat energy is what causes greenhouse effect. Sun is the main source of heat energy on earth. Greenhouse gases allow sunlight, shortwave radiations, to pass through the atmosphere freely, where some of it gets absorbed by the earth’s surface and the remaining bounces back out towards the space in the form of heat. A portion of this is then trapped by the greenhouse gases present in the atmosphere. It is the shape of these compounds which allow them to trap and then re-emit the heat towards the ground which increases the temperature of the globe. Natural greenhouse effect maintains the temperature of the earth and makes it suitable for the life to exist. It shows that basically these gases have a great role in making the life possible on the earth – without them the average temperature on the earth would be -18 °C! But they become a source of great trouble when their concentration in the atmosphere grows to the level where they cause century-scale rise in temperature of the earth’s climate system, also known as global warming, and as a result of it we observe rise in sea level because of the melting of glaciers and ice caps, extreme weather events like cyclones, droughts and floods, increase in the rate of evaporation which causes extreme rainfalls and snow events around the globe and much more.
You may think what this explanation has to do with Pakistan, CPEC, coal and energy. The biggest problem associated with burning coal is that it releases a number of pollutants and airborne toxins which contribute to climate change and negatively affect human health. Carbon dioxide which is the major output of coal combustion is a forcing greenhouse gas! We call it forcing because it takes many years to leave the atmosphere. Methane also comes in the same category. It is not a by-product of coal combustion but is formed as part of the process of coal formation. Thus it gets released from the coal seam and surrounding disturbed rock strata when coal is mined. China Pakistan Economic Corridor, as I already have mentioned, includes majority of coal-fired power plant projects and with that it also includes project under which 1.57 billion tons of lignite coal will be extracted (3.8 billion tons per annum in first phase as “Early Harvest” stage of the economic corridor) from the allocated area of Block II in Tharparkar.
Sindh Engro Coal Mining Company (SECMC), a joint venture company with the Government of Sindh, Engro Powergen and Affiliates namely, Thal Ltd. (House of Habib), Hub Power Company, Habib Bank Limited, China Machinery Engineering Corporation (CMEC) and State Power International Mendong (SPIM) will be responsible for the extraction of this coal which will be utilized by a mine-mouth power plant (a part of CPEC) having sub-critical power generation technology (emits approx. ≥880g CO2/kWh :Adapted from IEA, Technology Roadmaps, High-efficiency low-emissions coal-fired power generation, 2012) which is being established by Engro Powergen Limited, a Joint Venture Company of Engro Powergen, China Machinery and Engineering Company, Habib Bank Limited and Liberty Mills Limited. Commercial operation date for phase one of both Projects is expected to take place by mid – 2019.
There are total 7 coal-fired power plant projects under “Early Harvest” stage of CPEC. Out of these seven, 2 are currently operational, namely Coal-fired Power Plants at Port Qasim Karachi with generation capacity of 1320 MW and Sahiwal Coal Fired Power Plant with generation capacity of 1320 MW . Both are based on super critical technology which is efficient Up to 42%, emits 800-880g CO2/kWh and consumes 340-380g of coal per kWh. Other then these 2 plants 5 are either under construction or still need approval.
Engro Thar Block II 2×330MW Coal fired Power Plant (already discussed in paragraphs above), TEL 1×330MW Mine Mouth Lignite Fired Power Project at Thar Block-II and ThalNova 1×330MW Mine Mouth Lignite Fired Power Project at Thar Block-II which are collectively classified as Thar Block- II Coal Power Projects is currently under construction. This power station will use sub-critical power generation technology.
Sino Sindh Resources Limited (SSRL) Thar Coal Block-I Mine Mouth Power Plant (under-construction) , with generation capacity of 1320 MW will also have sub-critical power generation technology which is in general efficient up to 38% , emits ≥880g CO2 (Carbon dioxide) per kWh and consumes ≥380g of coal per kWh. These figures are same for all coal-fired power plants which use sub-critical technology. 6.5 million tons of coal per annum will be extracted from Block I of Thar coal mine. Never-ending hunger of coal!
China Power Hub Generation Company 1,320MW Coal-Fired Power Plant in Hub, Balochistan (needs approval of the provincial government of Balochistan) will have super-critical technology installed which is efficient Up to 42%, emits 800-880g CO2/kWh and consumes 340-380g of coal per kWh. Again, these figures are same for all coal-fired power plants based on super critical technology. Thar Mine Mouth Oracle Power Plant, with generation capacity of 1320 MW was elevated to the priority list of projects under the China-Pakistan Economic Corridor (CPEC) in June 2017 but is still in pre-permit development stage.
It is crystal clear that Pakistan’s romance with coal has no place for the environment. Seven priority coal-fired power projects, out of which two are currently operational and very soon all will together be polluting the environment with tons of carbon dioxide being emitted. Furthermore, coal extraction from Thar coal mines block I and II will pump bulk of methane into the atmosphere and altogether both power generation and mining projects will contribute to increased greenhouse effect in Pakistan. It shows that the environmental cost of the economic corridor is much more than its economic gains. Indeed a bitter truth. Most shocking part of the story is that China itself is putting more focus on renewable energy resources for its electricity demands but pushing Pakistan towards a fossil-fuel dominant energy structure. In 2017, China eliminated or suspended 65 gigawatts (GW) of coal-fired capacity which exceeded the national target of 50 gigawatts! The country has vowed to improve its notorious air pollution and upgrade its coal based energy structure by reducing coal consumption and boosting clean energy use.
According to the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5), global greenhouse gas (GHG) emissions have accelerated to an unprecedented level. The report indicates that in 21st century the global average temperature is likely to increase by 0.3°C to 1.7°C for their lowest emissions scenario, and 2.6°C to 4.8°C for business as usual carbon intense emissions. According to the report, to limit the global average temperature by 2°C, global GHG emission must have to be curtailed by 40 to 70 percent. High rate of carbon dioxide and methane emission from coal combustion and mining is posing a greater risk to the climate of Pakistan than ever before. Greenhouse gas inventory of Pakistan for the year 2011-12 show that the total carbon dioxide emission was 369 million tons of carbon dioxide equivalent (MtCO2e) . 45.9% of the total CO2 emission was contributed by energy sector, 44.8% from agriculture and livestock sector, 3.9% by industrial procedures and 2.6% from forestry sector. The situation is alarming! 90.7 % of the total emission bulk comes from energy and agricultural sector.
Now that you know greenhouse gases traps heat energy and when they re-emits it back toward the surface of the earth, results in the increase in average temperature, which we also called greenhouse effect. This effect is very prominent in Pakistan. According to the Asian Development Bank’s 2014 report, namely “Assessing the Cost of Climate Change and Adaptation in South Asia – Manila”, in the last century, warming trend of 0.57°C in the annual mean temperature was observed from 1901 to 2000 in Pakistan. From 1961 to 2007, an increase of 0.47°C, which was more accelerated, observed. According to the 2009 Technical Report by Pakistan Meteorological Department, winters got more affected as the average winter temperature for increased from 0.52°C to 1.12°C (province to province variation) . Highest increase in winter temperature was observed in the province of Balochistan. From 1960 to 2007, the average annual temperature in Pakistan got increased by 0.87°C (max) and 0.48°C (min) . The fact that winter temperature is increasing in all four provinces of Pakistan and that mean annual temperature showed an increasing trend, that is, increased by 0.57°C in 20th century makes it clear that greenhouse effect is very prominent in Pakistan and don’t forget to take into account the accelerated trend of warming, a rise of 0.47°C, from 1961 to 2007. Increasing winter temperature means more summer (warm days).
According to the Global Change Impact Studies Centre’s 2005 Final Technical Report for APN CAPaBLE Project , the annual and seasonal trends in the average annual temperature in different climatic zones of Pakistan from the year 1951 to 2000 are as follows : A) the average annual temperature has been increasing in most parts of the country. B) all the regions show an increasing trend for the pre-monsoon summer months (April-May). C) The Balochistan Plateau is getting hotter in all the seasons.
Increasing temperature affects water cycle in negative ways. A warmer climate means more evaporation from land (soil moisture) and water bodies (rivers, lakes, sea and oceans), thus it results in a rise in moisture holding capacity of the atmosphere, and when a storm passes through a warmer region holding more water, we witness heavy rainfall (an atmosphere with more moisture can produce more intense precipitations events, which is exactly what has been observed). For each degree rise in temperature, the moisture holding capacity of air goes up by 7%. Heavy precipitation doesn’t mean an increase in total rainfall over a season or over a year. This simply indicates a decrease in moderate rainfall, thus an increase in the length of dry periods. Moisture holding capacity of the atmosphere increases with increasing temperature but it doesn’t mean that increased moisture will fall evenly all over the country; rather some zones will see more extreme rainfalls while other areas will see less due to shifting weather patterns and other factors. Most immediate impact of heavy rainfall is the prospect of flooding. According to the statistics mentioned in Asian Development Bank’s 2013 report, namely, “Indus Basin Floods: Mechanism, Impacts and Management. Manila” , the super flood of 2010 in Pakistan, alone resulted in over 1,600 casualties. Furthermore, it inundated an area of 38,600 square kilometers and caused damage worth USD 10 billion! In addition to flooding, intense rainfall also increases the risk of landslides. When above-normal downpour increases the water table and saturates the ground, it results unstable slopes, causing a landslide. According to 2014 “Climate Change and Infrastructure, Urban Systems, and Vulnerabilities: Technical Report for the US Department of Energy in Support of the National Climate Assessment. Island Press”, heavy rainfall-induced landslides in mountainous urban centers have been observed in Pakistan.
Global Change Impact Studies Centre’s 2005 Final Technical Report for APN CAPaBLE Project says that annual precipitation has been increased by 61 mm in Pakistan from 1901 to 2007. Monsoon rains increased by 22.6 mm and winter precipitation got raised by 20.8 mm. The report summarized that annual precipitation has generally been increasing except coastal areas.
With increase in global temperature, it is observed that oceans are expanding (thermal expansion) and glaciers are melting, thus it results in global mean sea level rise. Intergovernmental Panel On Climate Change (IPCC) Fifth Assessment Report (AR5) says that global mean sea level rose to 0.19 meter over the period of 1901-2010. Sea level rise for Pakistan is estimated at 1.1 millimeter per year from 1856 to 2000 along the coast of Karachi (Arabian Sea coast). (Source: The Impact of Sea Level Rise on Pakistan’s Coastal Zones – In a Climate Change Scenario. 2nd International Maritime Conference at Bahria University, Karachi). According to IPCC’s fifth Assessment Report (AR5), mean sea level rise of 0.2 – 0.6 meter will be observed by the end of 21st century. Of course it will affect low-lying coastal areas of Karachi. Inundation of low-lying coastal areas, destruction of mangrove forests and reduction in fish and shrimp productivity (mangroves are breeding grounds for fishes and shrimps).
Let us now see the effects of climate change due to increased greenhouse effect (because of greenhouse gases emission, especially carbon dioxide and methane from coal-fired power plants and coal mining under CPEC respectively) on different sectors of Pakistan. Because of increase in annual mean temperature and precipitation, agriculture sector will be affected the most. Pakistan’s economy is agro-based, and it contributes 21% to the total GDP of the country. According to a report produced by World Wild Fund for Nature (WWF) Pakistan, by 2040, a rise in temperature (0.5°C to 2°C), agricultural productivity will decrease by 8-10 percent.(Source: A. Dehlavi et al. 2015. Climate Change Adaptation in the Indus Ecoregion: A Microeconometric Study of the Determinants, Impacts, and Cost Effectiveness of Adaptation Strategies. Islamabad: World Wide Fund for Nature (WWF) Pakistan). A study has shown that there will be a 6% decrease in wheat yield and 15 to 18% decrease in the yield of basmati rice will be observed across the country (except northern areas) by 2080. (Source: M. M. Iqbal et al. 2009. Climate Change Aspersions on Food Security of Pakistan. Science Vision. 15 (1). Islamabad.)
Due to increased greenhouse effect, increased recession of Hindu Kush- Karakoram- Himalayan (HKH) glaciers is observed. This will affect river flows in Indus River System. As Himalayan glaciers will be melting for next 50 years, water flow will raise in Indus River, but after that, because of no glacier reservoirs, flow will decrease substantially by 30 to 40 percent over the next 50 years. (Source: K. Hewitt. 2005. The Karakoram Anomaly? Glacier Expansion and the ‘Elevation Effect’, Karakoram Himalaya. Inner Asia. Mountain Research and Development: Special Issue – Climate Change in Mountains. 25 (4).). This variation won’t just affect the availability of water in upper and lower Indus but will also hit Pakistan’s overall agricultural sector. Increasing number of floods due to increase in heavy precipitation in the form of rain because of greenhouse effect, results in high sediment inflows in artificial water reservoirs (dams) and therefore reduces storage capacity.
Greenhouse gases emission from coal-fired power plants and coal mines, which are and will increase greenhouse effect (increase temperature) will affect the energy sector as well. Hotter temperatures will increase energy demands (increase in air-conditioning requirements) in summers and as a result more dirty energy from coal will be generated and thus more greenhouse gases emission. Himalayan glaciers are melting because of high annual mean temperature, which will reduce the availability of water for hydropower generation. Floods as a result of heavy precipitation will damage power plant infrastructure. Increased atmospheric temperature increases the temperature of water bodies. Nuclear and coal-fired power plants use water for cooling purpose. Not so cool water won’t be effective for cooling purpose, thus the efficiency of these plants get reduced.
System of transportation also gets affected by greenhouse effect. Heavy precipitation events cause flooding. Because of old infrastructure of road railways and airports extreme weather events affect their quality. Landslides (as discussed before) affect mountainous transportation.
Mining of coal in Thar Block II by SECMC (Sindh Engro Coal Mining Company- as discussed above), is done by open pit mining procedure because the coal is buried inside layers of ground water . Therefore, the water has to be pumped out of the mines and then it has to be stored somewhere. SECMC has planned to build an effluent disposal reservoir (near Gorano village) in which this waste water will be stored for two and a half years (or more). In 2016, people living in this area protested to stop the construction of reservoir. The waste water will contain Total Dissolved Solids (TDS) , the quantity of which is around 5000 ppm, which is much higher than the World Health Organization (WHO) standards, that sets the maximum contaminant level for TDS at 1000 ppm. People of Gorano village are worried about the seepage from this reservoir, that will possibly damage the quality of the underground water which is being used by them for drinking, farming and other daily life purposes. Furthermore, coal mines puncture and drain groundwater reservoirs in its vicinity and thereby depriving communities living around from the precious natural resource – water! Before burning coal, it is washed to clean it from impurities. This wastewater, full of harmful toxins has to be disposed off somewhere. In Pakistan where no one cares about following rules and regulations, this water could end up being disposed in nearby lakes and rivers. On one hand it makes the water undrinkable and on the other, destroys fresh water habitat.
Combustion of coal not only pollutes air with carbon dioxide, but also with other harmful pollutants, which negatively affect human health. Mercury emissions from coal fired power plants damage nervous, digestive and immune system in human beings. 1/70th of a teaspoon of mercury deposited on a 25-acre lake can make fish unsafe to eat. Sulfur dioxide (SO2), which is produced when sulfur in coal reacts with oxygen, when reacts with other molecules in atmosphere it produces acidic particulates. When these particulates are inhaled they can cause asthma and bronchitis. Sulfur dioxide is also responsible for acid rain! These plants also emits nitrous oxides (NOx), which when inhaled can cause irritation of lung tissues and make the inhaler susceptible to chronic respiratory diseases like pneumonia and influenza.
Coal ash, which is the by-product of coal combustion and contains concentrated heavy metals, including many known carcinogenic and neurotoxic chemicals, is either buried underground or stored in open reservoirs. During heavy precipitation event, this highly toxic ash mixes with water that runs off into nearby fresh water bodies and pollutes them.
So what is the ultimate purpose of CPEC? At such hefty environmental cost, all that economic prosperity becomes meaningless. You are digging in the land of Thar for coal and at the same time depriving the communities living there of fresh water! Because of greenhouse effect, Himalayan glaciers are melting which is affecting water flow in Indus river system has been affected, crop yields are reducing, people are dying from extreme weather events like floods, droughts and heat waves, coastal land is inundating due to sea level rise, transport infrastructure is being destroyed by heavy precipitation and people are inhaling polluted air and drinking water full of carcinogenic and neurotoxic pollutants because we want energy form coal! World is progressing. Countries, including China are reducing their fossil fuel energy infrastructure and boosting the use of renewable energy resources. Protecting climate is necessary. For Pakistan burning coal for energy is like firing your own house for some heat! Stop it! Stop burning coal!

IRENA Outlines Importance of Energy Transition in Global Innovation Index
The International Renewable Energy Agency (IRENA) has outlined the innovation priorities needed to accelerate the transition to a sustainable energy system. The Agency authored a chapter of the recently published 2018 Global Innovation Index (GII) report, named Innovation Driving the Energy Transition in which four central policy-level innovation recommendations are outlined as critical to scaling-up renewable energy deployment.
The chapter also charts the development of various renewable technologies, categorising their viability and deployment progress. Applications seen as being ‘on track’ include wind and solar PV power technologies together with electric vehicle development, while areas in need of further innovations to improve their economics and adoption rates include biofuels and solar thermal heat applications, the chapter highlights.
The 11th edition of the World Intellectual Property Organisation’s (WIPO) global innovation index report, themed Energizing the World with Innovation analysed the state of energy sector innovation, identifying areas where further effort is required, and where breakthroughs in fields such as energy production, storage, distribution, consumption, and decarbonisation are taking place. IRENA’s chapter makes the following policy-level recommendations:
- Foster a system wide approach to innovation, beyond research and development
Innovations in technology, together with innovative approaches to enabling infrastructure, business models and system operation, must all be pursued with equal assiduousness, IRENA points out. “Leveraging synergies between innovations across all sectors and components of the energy system, and involving all actors, is crucial for the transition,” said Dolf Gielen, Director of IRENA’s Innovation and Technology Centre.
- Strengthen international cooperation to nurture innovation
Innovation is central to decarbonising the energy sector, and international cooperation is critical to innovation, IRENA points out. To stimulate the breakthroughs necessary to advance the energy transition, existing platforms designed to foster international collaboration should be prioritised at a national level. This allows countries to share ideas, pool resources and capital, and co-develop programmes that support common interests.
- Advance power system integration
The business case for renewable power generation is now unquestionable, with power generation costs now falling well within the fossil fuel cost range. Yet despite the strong business case, achieving the world’s full resource potential requires a significant scaling-up of the share of renewable power in global electricity systems from a quarter today, to around 85 per cent by 2050. This requires efforts to promote systems integration by increasing the flexibility of power systems in supply and demand.
- Support a portfolio of technology options to electrify and decarbonise end-use sectors
The electrification and decarbonisation of end-use sectors such as transportation, heating, cooling and industry lags the renewables momentum for power generation, yet end-use sectors represent close to 60 per cent of energy related CO2 emissions. A combination of electrification, technology breakthroughs, and sector-specific global agreements for decarbonisation, are needed according to IRENA’s recent analysis. Francisco Boshell, Analyst – Renewable Energy Technology, Standards and Markets at IRENA said: “Electrifying energy demand of end-use sectors represents a ‘win-win’ that can reduce emissions whilst supporting the integration of higher shares of renewable power.” IRENA indicates that pursuing electrification can double the share of electricity in final energy use in the coming decades.
10 tips to stay cool in today’s heat
Across the world, extreme weather and prolonged heat waves are setting records. In Europe, the historical heat record – set in Athens 41 years ago – may be broken today if parts of Spain and Portugal creep above 48°C. In Japan, temperatures are still in the mid-30s after Tokyo saw its highest ever recorded temperature of 41°C in late July. And in South Korea as many as 29 people died from heatstroke this week, after temperatures in Seoul hit a 111 year high. Beijing also broke a 50-year record in June.
Understandably, this has driven a demand for cooling. Recent reports in France, which is presently suffering its second heat wave this summer, show that sales of household fans in July increased 125% over last year, while air conditioner (AC) sales jumped nearly 200% compared to 2017. In Montreal, stores ran out of ACs during the prolonged heat wave in July. And in India, AC producers expect that sales this year will reach double-digit growth as rising household incomes – paired with recent high temperatures – lead to greater demand for cooling services.
This growing demand is part of a major global emerging trend: rising need for cooling comfort – and in particular air conditioners. Cooling is now the fastest growing use of energy in buildings, and ACs and electric fans already account for about 10% of all global electricity consumption. This is one of the most critical blind spots in the energy world today – by 2050, cooling demand could more than triple. Our recent report on the Future of Cooling highlights why this is such a dilemma: while greater access to much needed cooling services is a good thing, it could place a major strain on energy systems if we don’t do something about how efficiently we keep cool.
Fortunately, there are many solutions – many of which we can all take today. Here’s a list of ten things we can all do to be cool, efficiently:
Shut your shades and close the blinds. As much as 80% or more of the heat from the sun can be transmitted through your windows. This solar heat gain is a significant factor in the need for cooling in buildings. In the short term, keeping the curtains drawn or the shades shut can make a big difference in how much of the sun’s heat comes indoors. If you’re thinking of replacing your windows, ask for a low-emissivity coating to let the light in but keep the solar heat out.
Use fans and ventilation. The power consumption of a fan is typically between 25 and 150 Watts, compared to a small AC unit that is often between 1 000 and 1 500 Watts. So before turning on that AC, think about using a fan. And when you can, letting a little air in can make a world of difference, especially when cooler nights set in or when there is a good breeze.
Take a second look at your thermostat. Raising the temperature set point on your AC by 1°C can reduce its energy consumption by as much as 10%. Most ACs use a vapour compression cycle, moving heat from the inside to the outside by using energy. Just like us, the more work they do, the more energy they burn. So the next time you go to touch that dial, think about turning it up a notch.
Take a second look at what you’re wearing. Experiences with programmes like Japan’s Cool Biz (which encourages employees to ditch the ties and formal wear in summertime) show that appropriate summer attire can let people stay comfortable at higher indoor temperatures. The next time you think about throwing on a sweater in summer, consider raising the thermostat first.
Maintain your AC. Something as simple as a clogged filter can lower AC performance by 5% to 15%. Neglecting regular maintenance of AC filters, coils and fins (all the pieces that help exchange the heat from the inside to the outside) can lead to poor energy performance. Making sure your AC passes a good bill of health (preferably through a trained technician) can improve its performance and cut down on your energy bill.
Keep an eye out for energy labels. If you’re buying an AC or replacing an existing model, be sure to take a look at the AC energy label (or if you can’t find one, try looking for product information online). Our Future of Cooling report finds that people often buy ACs that are significantly less efficient than what is available on shelves – even when the more efficient ACs are similarly priced. Be cool and take a look at the energy performance label to buy the most efficient choice.
Get a programmable or smart thermostat. A smart thermostat can cut AC energy use by as much as 15% or more. Programmable thermostats can also cut back on energy demand by setting fixed hours for AC operations. Smart thermostats take this a step further by monitoring, predicting and adjusting cooling needs to cut back on energy use when and where it is needed. So keep cool and let your thermostat do the thinking for you.
Part-time, part-space is part of the solution. Research by the IEA Technology Collaboration Programme on Energy in Buildings and Communities found that household electricity use for cooling can be as much as 10 times lower when ACs are only used as and where needed. This can be as simple as turning off the AC when you leave a room. Try turning on your AC to get comfortable before going to bed and then turning it off when you go to sleep. Or get a smart thermostat to monitor and control when your AC goes on.
Watch out for those pesky plug loads. On really hot days, think twice before using your stove, running the washing machine or turning on the dishwasher. Electrical plug loads – ranging from large appliances to computers and hair-dryers – all generate heat when operating. Avoid heat build-up in your home by turning those devices off for the day and reduce your electricity consumption at the same time.
Build it right. The building envelope – the parts of a building that form the primary thermal barrier between interior and exterior – plays a key role in how much energy is required to heat and cool a building. Cool roofs, awnings and insulation can all help cut down on the need for mechanical cooling. Let in the light but keep out the heat with double-glazed, low-e windows. And don’t forget to seal those cracks with proper air sealing. So when renovating or building, make sure to build it right and keep cool for years to come.
