Ethical drugs, unethical practices
by Geewananda Gunawardana, Ph.D.
Ensuring the quality, safety, and efficacy of pharmaceuticals requires a high level of constant vigilance. A good example is the four deaths caused by contaminated eye drops in the USA last May despite the well-regulated and best prepared monitoring of the drug supply by the US Food and Drug Administration. Unfortunately, the consumers in places where regulations as well as their implementations fall short of ideals can fall victims much more frequently: A World health Organization (WHO) report finds that about 10% of the world’s drug supply is either subpar or fake. Global deaths among children alone due to subpar drugs is over 150 thousand annually while the economic cost is estimated to be about US $ 200 billion.
While loss of life is a tragedy, the failure to ensure the quality of medicinal products can have far reaching and long-lasting consequences of much larger magnitude. The emergence of drug resistant infections and parasitic diseases and genetic disorders due to subpar drugs will only come to light in the long run.
To get some idea about the vulnerability of pharmaceuticals, it is important to know the way the regulatory process works. Almost 90% of the new drug development takes place in North America and Europe. The rest is divided among Japan and Israel. India and China, leaders in generic drug manufacture, are only beginning to enter this field through collaboration with American and European pharmaceutical companies. When a drug is invented, the inventor obtains a patent, which is an exclusive right to market it for 20 years. However, a patent only keeps the competition away, and it does not give the authority to market the drug, which must be obtained from the regulatory agency of the respective country.
To get the marketing authority, a vast amount of data must be produced showing efficacy, safety, and manufacturability of the drug. This process takes 10 to 12 years on average and over US $ 1.5 billion in R&D costs. As the development takes up to 8 to 10 years, the actual patent life left when it goes to market is reduced to 10 to 12 years, during which time the company must recoup all the costs and make a profit. A drug marketed under patent is known as a brand name drug. These initial R&D costs make the brand name drugs expensive.
The manufacturer of the brand name drug must follow all the current good manufacturing practices (cGMP) as specified by the regulatory agency of the marketed countries. The International Conference on Harmonisation (ICH) has standardised these guidelines and are followed by the major pharmaceutical manufacturing countries. Adherence to the cGMP regulations assures the identity, strength, quality, and purity of drug products by requiring that manufacturers of medications adequately control manufacturing operations.
The consequences of failing to meet guidance can be harsh. For example, the UK based Glaxo Smith Kline was fined US$ 3 billion in 2012, the highest in history for cGMP violations. The brand name drug manufacturers avoid taking any risks as the stakes are very high. There are some companies that were forced to shut down for failing to follow cGMP. A common problem with brand name drugs is the manufacture of counterfeit drugs sold in small markets despite the best efforts of the patent owner to avoid such piracy. The commitment to quality and the stringent regulatory vigilance makes brand name drugs less susceptible for quality issues.
Once the patent expires, anyone with the right capabilities can manufacture the drug and seek marketing authorisation in selected countries. These drugs are referred to as generic drugs. Since the generic manufacturers do not have to bear the billion-dollar R&D costs, they can afford to lower the price. The competition for market share also drastically reduces the cost of generic drugs, often by over 80% of the original price. The costs can be further reduced by moving the manufacturing into places where the labor and operating costs are lower and occupational safety and environmental regulations are lax or lacking altogether. The affordability and wide availability are the beneficial outcomes of generic drugs. For example, 91% of the drugs prescribed in the USA in 2022 were generic drugs. Except for a rare event, the US drug supply remains safe and reliable, mainly thanks to the diligence of the US Food and Drug Administration.
The bulk of these cost-effective generic drugs are destined for low- and middle-income countries. Unfortunately, that is where the troubles begin. The WHO has formulated international regulatory standards to ensure the safety and efficacy of the drugs in places where ICH guidance is not implemented. They also have a program for pre-qualification of drug manufacturing facilities when requested. While international organisations require WHO prequalification for drug purchases, individual governments can follow their own regulations. Knowing the presence of potential buyers who are willing to forgo cGMP requirements, some manufacturers tend to ignore the need for costly qualification or certification programms. This practice is also encouraged by the premise on the buyers’ side that testing alone can ensure the quality of drugs. However, the truth is that failing to follow cGMP can lead to unintended release of subpar drugs to markets even if the standard testing procedures are followed.
Two processes where this can happen easily are sterilisation and achieving content uniformity. Failure to ensure that every single unit of the drug, be it a pill or a vial of many thousands manufactured, is compliant could result in subpar drugs reaching the market. In the case of uneven sterilisation, microbial contamination can occur as was seen with eye drops. Failure to ensure uniformity can result in drug units containing either higher or lower doses than shown on the label.
Most of the generic drugs are manufactured in Asia. Drug manufacturing is a multistep process conducted in multiple locations under varying levels of regulatory control. A routine drug manufacture can have the following basic steps: procurement of raw materials, synthesis of starting materials and/or intermediates, synthesis of the active pharmaceutical ingredient (API), procurement of excipients, and formulation of the API into the drug product – capsule, tablet, syrup etc. This can vary for biologics such as vaccines and recombinant proteins etc., which make up only about 2% of all drugs used. In either case, at every step, the product must be stored in proper containers under the right conditions as determined based on its stability to prevent degradation and contamination.
Except for biologics, almost all drugs are produced by chemical synthesis. A small portion are either plant or microbial origin. The generic drug manufacturers come up with alternate synthetic routes that are cost effective. This creates a major problem: Any synthetic process generates impurities or side products in addition to the desired product. These impurities could have unknown properties, including toxicity, and must be removed or kept to a minimum using various purification steps. The processes and analytical methods used for this purpose by the brand name manufacturer are optimized to monitor and control any impurities specific to the raw materials, starting materials, and excipients they used. However, if the generic manufacturers introduce any changes, the standard quality control methods may not work, and undesired impurities will end up in the drug causing potential adverse events. Another potential problem, particularly in the warm and humid tropics, is microbial contamination, as happened with eye drops when handling and storage conditions are deviated.
With complicated supply chains, it is very difficult for the drug purchaser to track if all processes used in the manufacture of the drug were conducted under cGMP. Either they do not have the wherewithal or have no impetus altogether as happens when questionable drug procurement methods are followed. There are other ways the purity of drugs can be compromised. All drugs have a limited lifetime as specified by the expiration date. The expiration date is set assuming the storage of the drug under certain conditions and in designated containers. Any deviation, which can happen easily when transported between tropical locations, the drug can degrade reducing the potency or efficacy and introducing impurities. Without proper cGMP, it is not possible to know if such deviations have occurred.
If the drug is degraded, the desired therapeutic effect may not be achieved. In addition to that, in the case of antimicrobial and antiparasitic drugs, the administration of lower doses can lead to the development of drug resistant varieties. Infections caused by resistant organisms can be difficult, and sometimes impossible, to treat. Antimicrobial resistance is an urgent global public health threat that killed around 1.27 million people worldwide in 2019. If not controlled, this could render the current anti-infective drugs virtually useless and makes it one of the world’s most urgent public health problems.
The impurities or contaminants in drugs can have numerous undesired results including death. The deaths of 66 children in Gambia last year caused by taking contaminated cough syrup, imported from India, is just one example. A serious problem is contamination with genotoxic compounds. If not detected promptly, the consequences would not be known for many generations. The genotoxic impurities can be harmful when present in as low as parts per million amounts in the drug. The analytical techniques for detecting such low amounts require specific instruments not readily available in most laboratories. Recently, a whole family of hypertension drugs were found to contain genotoxic impurities and were withdrawn from the US markets.
These are the problems that can arise under normal operating procedures, and fortunately, the ones that can be eliminated if proper cGMP are observed. To worsen things, there are added problems that go beyond manufacture and cGMP. Unscrupulous drug companies and corrupt administrations contribute to the problem by knowingly allowing substandard drugs into healthcare systems with total disregard for life and limb. Pharmaceutical industry is notorious for its “gift” system for buying or prescribing their drugs. In one reported incident, a company sold 45 years’ worth of antibiotics to a developing country when the shelf life of the drug is only 2 years. Unloading drugs that are nearing expiration or not suitable for their own countries into low-income countries is a common practice.
The subpar drug related adverse events are predictable but also preventable. Generic drugs in general are safe and effective as international organizations have provided the means to ensure their safety and efficacy. Every step from the supply of starting materials to the dispensing of the drug to the patient must be controlled according to the guidance to receive the full benefits of drugs and avoid adversities. Sri Lanka has incorporated most of those rules and regulations to their own. However, their complete implementation remains questionable. Purchasing drugs without knowing its complete history is inviting trouble. Neglecting to do so puts future generations at risk in addition to wasting hard-earned foreign exchange.

The Ramadan War
A Strategic Assessment of a Conflict Still Unresolved
The Unites States of America and its ally, Israel attacked Iran on 28 February, or the 10th day of the month of Ramadan. More than a month of intense fighting has passed since, and the Ramadan War has settled into a grinding, attritional struggle that defies early declarations of victory. Despite sustained U.S. and Israeli air and naval bombardment, Iran remains standing, and continues to strike back with a level of resilience that has surprised many observers. The conflict has evolved into a contest of endurance, adaptation, and strategic innovation, with each side attempting to impose costs the other cannot bear.
Iran’s response to the overwhelming airpower of its adversaries has been both simple and devastatingly effective: saturate enemy defences with swarms of inexpensive drones and older ballistic missiles, forcing them to expend costly interceptors and reveal radar positions, and then follow up with salvos of its most advanced precisionguided missiles. This layered approach has inflicted severe physical damage on Israel and has shaken its national morale. The country has endured repeated missile barrages from Iran and rocket fire from Hezbollah, straining its airdefence network and pushing its civilian population to the limits of endurance.
The United States, meanwhile, has been forced to evacuate or reduce operations at several bases in the Gulf region due to persistent Iranian drone and missile attacks. For both the U.S. and Israel, the war has become a test of strategic credibility. For Iran, by contrast, victory is defined not by territorial gains or decisive battlefield outcomes, but by survival, and by continuing to impose costs on its adversaries.
The central strategic objective for the U.S. has now crystallised: reopening the Strait of Hormuz to secure global energy flows. Ironically, the Strait was open before the war began; it is the conflict itself that has rendered it effectively closed. Air and naval power alone cannot achieve this objective. The geography of the Strait, combined with Iran’s layered defences, means that any lasting solution will require ground forces, a reality that carries enormous risks.
U.S. Strategic Options
The United States faces five broad operational options, each with significant drawbacks.
1. Seizing Kharg Island
Kharg Island handles roughly 90% of Iran’s oil exports, making it an attractive target. However, it lies only a short distance from the Iranian mainland, where entrenched Iranian forces maintain dense networks of missile batteries, drones, artillery, and coastal defences. Any attempt to seize Kharg would require first neutralising or capturing the adjacent coastline, a costly amphibious and ground operation.
Even if successful, this would not reopen the Strait of Hormuz. It would merely deprive Iran of export capacity, which is not the primary U.S. objective. At least ostensibly not; there are those who argue that the U.S. simply wants to take over Iran’s petroleum (see below).
2. Forcing the Strait of Hormuz by Naval Power
Sending U.S. naval forces directly through the Strait is theoretically possible but operationally hazardous. Iran has mined all but a narrow channel hugging its own shoreline. That channel is covered by overlapping fields of antiship missiles, drones, artillery, and coastal radar. Clearing the mines would require prolonged operations under fire. Attempting to push through without clearing them would risk catastrophic losses.
3. Capturing Qeshm, Hengam, Larak, and Hormuz Islands
These islands dominate the Iranian side of the Strait and host radar, missile, and drone installations. Capturing them would degrade Iran’s ability to close the Strait, but the islands are heavily fortified, and the surrounding waters are mined. Amphibious assaults against defended islands are among the most difficult military operations. Even success would not guarantee the Strait’s longterm security unless the mainland launch sites were also neutralised.
4. Invading Southern Iraq and Crossing into Khuzestan
This option would involve U.S. forces advancing through southern Iraq, crossing the Shatt alArab waterway, and pushing into Iran’s Khuzestan province — home to most of Iran’s oilfields. The terrain is difficult: marshes, waterways, and narrow approaches. Iranian forces occupy the high ground overlooking the plains.
While this route would allow Saudi armoured forces to participate, it would also expose U.S. and allied logistics to attacks by Iraqi Shia militias, who have already demonstrated their willingness to target U.S. assets. The political and operational risks are immense.
5. Capturing Chabahar and Advancing Along the Coast
The most strategically promising — though still costly — option is seizing the port of Chabahar in southeastern Iran and advancing roughly 660 kilometres along the coast toward Bandar Abbas. This approach offers several advantages:
· Distance from Iran’s core population centres complicates Iranian logistics.
· Chabahar’s deepwater port (16m draught)
would provide a valuable logistics hub.
· U.S. carriers could remain at safer standoff distances
, supporting operations without entering the Strait.
· The coastal route allows naval gunfire and missile support
to assist advancing ground forces.
· Local Baluchi insurgents
could provide intelligence and limited support.
· Capturing Bandar Abbas would
outflank Iran’s island defences and effectively reopen the Strait.
This option is likely to form the backbone of any U.S. ground campaign, potentially supplemented by diversionary attacks by regional partners to stretch Iranian defences.
The Limits of U.S. Superiority
The United States retains overwhelming superiority in naval power and manned airpower. But whether this advantage translates into dominance in unmanned systems or ground combat is far from certain.
The 2003 invasion of Iraq is often cited as a model of U.S. military prowess, but the comparison is misleading. Iraq in 2003 had been crippled by a decade of sanctions. Its forces lacked modern mines, antitank missiles, and effective air defences. Tank crews had little training; some could not hit targets at pointblank range. RPG teams were similarly unprepared. The U.S. enjoyed numerical superiority in the theatre and total control of the air, allowing it to isolate Iraqi units and prevent reinforcement.
Even under those favourable conditions, Iraqi forces managed to delay the U.S. advance. At one point, forward U.S. units nearly ran out of ammunition and supplies, forcing the diversion of forces intended for the assault on Baghdad to secure the lines of communication.
Iran is not Iraq in 2003. Its armed forces and industrial base have adapted to nearly half a century of sanctions. It produces its own drones, missiles, artillery, and armoured vehicles. It has built extensive underground facilities, hardened command posts, and redundant communication networks.
Moreover, the battlefield itself has changed. The RussoUkrainian war demonstrated that deep armoured penetrations – once the hallmark of U.S. doctrine – are now extremely vulnerable to drones, loitering munitions, and precision artillery. The result has been a return to attritional warfare reminiscent of the First World War, with front lines stabilising into trench networks.
Yet, as in the First World War, stalemate has been broken not by massed assaults but by small, highly trained teams infiltrating thinly held lines, identifying targets, and guiding drones and artillery onto enemy positions deep in the rear. Iran has studied these lessons closely.
Mosaic Defence and Transformational Warfare
Iran’s military doctrine has evolved significantly over the past two decades. Its “mosaic defence” decentralises command and control, ensuring that even if senior leadership is targeted, local units can continue operating autonomously. This structure proved resilient during the initial waves of U.S. and Israeli strikes.
Iran has also absorbed lessons from U.S. “shock and awe” operations. The botched U.S. invasion of Grenada in 1983 exposed weaknesses in joint operations, prompting the development of “effectsbased operations,” “rapid dominance” and the broader concept of “transformational warfare.” These doctrines (better known colloquially as “Shock and Awe”), influenced by Liddell Hart and Sun Tzu, emphasised simultaneous strikes on strategic targets to paralyse the enemy’s decisionmaking.
While the U.S. struggled to apply these concepts effectively in Iraq and Iran, Tehran has adapted them for asymmetric use. Its drone and missile campaigns have targeted not only military assets but also economic infrastructure and psychological resilience. Israel’s economy and morale have been severely tested, and the United States finds itself entangled in a conflict that offers no easy exit.
Iran has also pursued a broader strategic objective: undermining the petrodollar system that underpins U.S. financial dominance. By disrupting energy flows and encouraging alternative trading mechanisms, Iran seeks to weaken the economic foundations of U.S. power.
Will the USA Achieve Its War Aims?
The United States’ core objective appears to be securing control over global energy flows by reopening the Strait of Hormuz and limiting China’s access to Middle Eastern oil before it can transition to alternative energy sources. Whether this objective is achievable remains uncertain.
A ground campaign would be long, costly, and politically fraught. Iran’s defences are deep, layered, and adaptive. Its drone and missile capabilities have already demonstrated their ability to impose significant costs on technologically superior adversaries. Regional allies are cautious, and global support for a prolonged conflict is limited.
The United States retains overwhelming military power, but power alone does not guarantee strategic success. Iran’s strategy is simple: survive, adapt, and continue imposing costs. In asymmetric conflicts, survival itself can constitute victory.
In Frank Herbert’s Dune, the protagonist, Paul Muad’dib says “he who can destroy a thing, controls a thing.” This is the essence of Iranian strategy – they have a stranglehold on petroleum supply, and can destroy the world economy. Trump has had to loosen sanctions on both Iran’s and Russia’s oil, simply to prevent economic collapse.
The Ramadan War has already reshaped regional dynamics. Whether it reshapes global power structures will depend on how the next phase unfolds, and whether the United States is willing to pay the price required to achieve its aims.

Nayanandaya:A literary autopsy of Sri Lanka’s Middle Class
“Nayanandaya,” meaning the enchantment of indebtedness, is Surath de Mel’s latest novel. True to his reputation as a maximalist writer, de Mel traverses the labyrinth of middle-class struggles; poverty, unemployment, the quest for education, through a father’s fragile dreams. The novel unfolds around Mahela, his son, his friendships, and the fragile relationships that keep him tethered to life.
“Happiness is not a destination; it is a journey. There are no shortcuts to it. At some point, the path you thought was right will be wrong. You have to make sacrifices for it.”
These words, uttered by the protagonist Mahela to his ten-year-old son, is the silent mantra of every middle-class parent. A common urban middle-class father’s yearning for his child to climb the ladder he himself could not ascend.
A Socio-Political Mirror
Sri Lanka’s middle class remains trapped in paradox. They are educated but underemployed, salaried but indebted, socially respected yet politically invisible. Structural inequalities, economic volatility and populist politics inclusively contribute to keep them “forever middle”.
Through protagonist Mahela, who is sometimes a graphic designer, sometimes a vendor and always a failure Surath de Mel sketches the deficiencies of an education system that does not nurture skills of the students. Sri Lanka boasts about high literacy rates, yet the economy cannot absorb the thousands of graduates produced into meaningful work. Underemployment becomes the inheritance of the middle class. With political connections often the stories can be transformed. De Mel pens it in dark humour to expose these truths:
“Some notorious writer once sneered in a newspaper, ‘Give your ass to the minister, and you’ll earn the right to keep it on a bigger chair.’ Countless people waiting in ministers’ offices, pressing
their backsides to seats, carrying the weight of their own lives.”
Childhood Trauma and Its Echoes
Surath de Mel frequently weaves psychoanalysis into his fiction. In Nayanandaya, he captures the lingering shadows of childhood trauma. Mahela, scarred by a loveless and fractured youth, suffers phobic anxiety and depression, apparently with a personality disorder as an adult. His confession at the psychologist reveals it out:
“Childhood? I didn’t have one. I was fifteen when I was born.”
Here, Mahela marks his true birth not at infancy, but at the death of his parents. This statement itself reveals the childhood trauma the protagonist had gone through and the reader can attribute his subsequent psychological struggles as the cause of it.
From a Lacanian perspective, trauma is not just something that happens to a child; it is a deep break in how the child understands the world, themselves, and others. Some experiences are too painful to be put into words. Lacan calls this the Real — what cannot be fully spoken or explained. This pain does not disappear but returns later in life as anxiety, fear, or obsessive compulsive disorder.
This trauma disturbs the child’s sense of self and their place in society. When language fails to make sense of loss, the mind creates fantasies to survive. These fantasies quietly shape adult desires, relationships, and choices.
In Nayanandaya, childhood trauma of the protagonist does not stay buried — it lives on, shaping the adulthood in unseen ways. In the narrative, Mahela’s struggles are not just personal failures but the result of a past that was never given words.
Tears of Fathers – Forgotten in Sri Lankan Literature
Sri Lankan literature has long been attentive to suffering — especially rural poverty, social injustice, and the silent endurance of women and single mothers. Countless novels, poems, and songs have given voice to maternal sacrifice, female resilience, and women’s oppression.
Yet, within this rich narratives, the quiet grief of the urban middle-class father remains mostly unseen. Rarely does fiction pause to examine the emotional lives of men who shoulder responsibility without language for their pain. These masculine tears are private, swallowed by routinely and masked by humour or silence. Definitely never granted literary space.
In Nayanandaya, Surath de Mel breaks this silence. Through Mahela, he lends voice to these overlooked men — fathers whose love is expressed through sacrifice rather than speech. However, de Mel does not romanticise the tears. Rather he humanises them. He allows their vulnerabilities, anxieties, and quiet despair to surface with honesty and compassion. In doing so, Nayanandaya fills a striking gap in Sri Lankan literature, reminding us that fathers, too, carry invisible wounds.
Literary value
With Nayanandaya, Surath de Mel reaches a new pinnacle in his literary craft. His language is dense yet lyrical, enriched with similes, metaphors, irony, and a full range of literary tools deployed with confidence and control.
One of the novel’s most touching narrative choices is the personification of Mahela’s son’s soft toy, Wonie. Through personified Wonie, de Mel captures the two most touching incidents in the entire novel . This simply reveals the author’s artistic maturity, transforming a simple object into a powerful emotional conduit that anchors the novel’s tenderness amidst its despair.
At a deeper symbolic level, Mahela himself can be read as more than an individual character, but a metaphor for Sri Lanka — a nation struggling under economic hardship, clinging to impractical dreams, witnessing the migration of its people, and drifting towards a slow, painful exhaustion. His personal failures could mirror the broader decay of social and economic structures. This symbolic reading lends Nayanandaya a haunting national resonance.
Today, many write and many publish, but only a few transform language into literature that lingers in the reader’s mind long after the final page. Surath de Mel belongs to that rare few. In a literary landscape crowded with voices, he remains devoted to art rather than popularity or trend. As a scholar of Sinhala language and literature, de Mel writes with intellectual depth, dark humour, and deep human empathy.
In conclusion, Nayanandaya is not merely a story; it is social commentary, psychoanalytic reflection, and tragic poetry woven into richly textured prose. With this novel — a masterful interlacing of love, debt, and fragile dreams — Surath de Mel engraves a distinctly Dostoevskian signature into Sinhala literature.

Domestic Energy Saving
Around 40 percent of the annual energy we use is consumed in domestic activities. Energy is costly, and supply is not unlimited. Unfortunately, we realize the importance of energy – saving only during the time of a crisis.
If you adopt readily affordable energy-saving strategies, you will cut down your living expenditure substantially, relieving the energy burden of the nation. Here are some tips.
Cooking:
Cooking consumes a good portion of domestic energy demand and common practices, and negligence leads to 30 – 40 percent wastage. A simple experiment revealed that the energy expenditure in boiling an egg with the usual unnecessary excess water in an open pan is nearly 50 percent higher than boiling in a closed lid pan with the minimal amount of water. In an open pan, a large quantity of heat is lost via convection currents and expulsion of water vapor, carrying excessive amounts of heat energy (latent heat of vaporisation). Still, most of us boil potatoes for prolonged intervals of time in open receptacles, failing to realise that it is faster and more efficient to boil potatoes or any other food material in a closed pan. About 30 – 40 percent of domestic cooking energy requirements can be cut down by cooking in closed-lid pans. Furthermore, food cooked in closed pans is healthier because of less mixing with air that causes food oxidation. Fat oxidation generates toxic substances. In a closed- lid utensil (not tightly closed), food is covered with a blanket of water vapor at a positive pressure, preventing entry of air and therefore food oxidation.
Overcooking is another bad habit that not only wastes energy but also degrades the nutritional value of food.
Electric kettle:
For making morning or evening tea or preparing tea to serve a visitor. Do not pour an unnecessarily large quantity of water into the electric kettle. Note that the energy needed to make 10 cups of tea is ten times that of one cup.
Electric Ovens:
Avoid the use of electric ovens as far as possible. Remember that foods cooked at higher temperatures are generally unhealthy, and even carcinogens are formed when food is fried at higher temperatures in an oven. If ever you need to bake something in an oven, limit the number of times you open the door. Use smaller ovens adequate for the purpose and not larger ones just for fashion.
Refrigerators:
Refrigerators consume lots of energy. Do not use over-capacity refrigerators just for fashion. Every time you open the fridge, more electricity is used to reset the cooling temperature. Plan your access to the appliance accordingly. Check whether the doors are properly secured and there are no leakages. Keep the fridge in a cooler location, not hit by direct sunlight and away from warmer places in the kitchen. Remember that turning off the fridge frequently will not save energy, instead it draws more energy.
Use of gas burners:
Do not use oversized utensils. Keep the lid closed as far as possible to prevent the escape of heat. Remember that excessive amounts of heat energy are carried away by a large surface-area conducting utensil. Do not open the gas vent to allow the flame to flash outside the vessel. A flame not impinging on the pan would not heat it, and gas is wasted. Ensure that the flame is blue. Frequently check whether gas vents are clogged with rust and carbon. Frequently, cooking material in the pan drops into the gas vents, and salt there corrodes the gas vents. Cleaning and washing would be necessary. Do not prolong cooking, taking time to prepare ingredients and adding them to the pan intermittently. Add ingredients at once and before switching the burner. If the preparation of a dish is prolonged to slow the cooking, use earthenware pots rather than metallic ones. An earthenware pot, being thermally less conducting retain heat.
Firewood for cooking:
Do not attempt to eliminate the use of firewood in cooking. If you are living in a village area, the exclusive use of LPG gas is an unnecessary expenditure. Large smoke-free, efficient oven designs are now available. If you are compelled to use gas, keep the option of firewood ovens, especially for prolonged cooking. Admittedly, there are locations, especially in cities, where the use of firewood is unsuited.
Hot water showers:
Before installing hot water showers, reconsider whether they are really necessary in a hot tropical climate. Go for solar water heaters, although the installation cost is high. Instant water heaters consume much less electricity compared to geysers with water tanks. Now, cheap and safe instant water heaters are available.
Lighting:
Arrange and design your residence to optimise daytime illumination until late evening. If you are constructing a new house, take this issue into account. Use LED lamps, which provide the same illumination for 85 percent less energy. In study rooms and areas that require prolonged illumination, paint the walls white. Angle – poised LED lamps with very low voltage are available. Use them for reading and studies. Routinely clean the surfaces of all lamps. Dust deposition cuts off light.
Air conditioning and ventilation:
Air conditioning consumes prohibitively large quantities of electrical energy. You can avoid air conditioning by optimising ventilation. The principle is to have air entry points (windows) in the house near the ground level and exit points (vents or windows) near the roof. Ground level is cooler, and the region near the roof is warmer. Thus, a cool air current enters the house near the ground level and hot air is drawn by the vents near the roof. The region near the ground can be rendered cooler by planting trees. Architectural designs are available to optimise this effect. You can sense the direction of air motion by holding a thin strip of paper near the windows at the ground and near the roof level. In addition to ceiling fan, install exhaust fans in the upper points of the house to remove hot air and draw cooler air through windows near the ground. Reduce the amount of sunlight hitting the roof by shading with trees. There are techniques for increasing the reflectance of the roof with paints and other designs.
Transportation:
A good portion of your budget is drained by transportation. Irrespective of who you are, use public transport if convenient and available. As much as possible, use the telephone and email to get your things done. If the officers do not comply for no valid reason, complain. Plan your trips to the town to do several things at the same time. Whenever possible, plan to share transport. Buy energy – efficient small vehicles. Routinely examine your vehicle for energy efficiency, i.e. correct tire pressure etc.
Charge electric vehicles off peak hours. Slow charging reduces heat generation in the circuit, reducing energy loss.
Energy is costly and limited in supply. Everything you do consumes energy. Be energy conscious in all your deeds. That attitude will reduce your expenditure, lessen the environmental degradation and financial burden of the nation in importing fuel.
Educating the general public is the most effective way of implementing energy-saving strategies.
