Flying into Kai Tak Airport, Hong Kong

Published

on

Hong Kong was a business centre and a popular intermediate port of call for all western countries for more than 800 years. Ships were anchored there before they ventured up the Pearl River to Canton (now Guangzhou) to conduct their business in commodities such as in tea, porcelain and silk. In return for these Chinese products, the British, to maintain the credit balance, introduced opium, grown in India, and sold it to China. Eventually, when China wanted to prohibit the importation and sale of opium, the British declared war. In 1842, after the end of the so-called first Opium war, China ceded Hong Kong Island to Britain. This was followed after the second Opium War ended. Britain obtained a 99-year lease of the now expanded Kowloon Peninsular and New Territories for a period of 99 years, commencing in 1898.

In 1925, the authorities acquired a strip of flat land for use as a flying club on a property near the Victoria Harbour, which was being reclaimed and developed by a Dr Ho Kai and Mr Au Tak. The airfield was also used by the Royal Air Force (RAF) and then in 1936, the first Imperial Airways aircraft, to land there, was a DH 86A Express (4-engine, biplane) with Cargo and just one passenger. 

During the Japanese occupation in WW 2, the original runway was extended using prisoners of war labour. Cathay Pacific Airways was founded after the war in 1946 with a solitary war surplus DC-3 named ‘Betsy’ with the initial intention of importing wool from Australia. Meanwhile, the population in Hong Kong was growing with refugees fleeing Communist China. To house them all many highrise buildings were constructed. As labour was cheap, luxury and electronic goods began to be also manufactured in abundance in Hong Kong. In 1958, the short runway, at what was now called the Kai Tak aerodrome, was extended to 8,000 ft. and then later extended to accommodate the wide body, big jets, such as the Boeing 747, Douglas DC10 and Lockheed L1011 Tri Stars.

The problem with Kai Tak was that the landing approach to one end of its runway was over the Hong Kong harbour, between high ground in Kowloon and Hong Kong Island, involving a low turn at 550 feet at 2.2 miles. Even for veteran pilots it was exciting, especially in bad weather with high wind and low visibility, to which Hong Kong is often subjected to. Eventually, it became the busiest single-runway, cargo airport in the world, working to its full capacity.

 From the early eighties, Air Lanka, too, had regular flights from Bangkok, Thailand to Hong Kong. During those days someone had built a cement factory in Hong Kong harbour and that used to spew out smoke. As a result, even on days with good weather the visibility was bad. On the hillside of a park called Lok Fu, at the end of the approach of the Instrument Guidance System (IGS), there was a ‘Checker board’ and pilots were expected to fly visually towards it.

Additionally, they had flashing lead in-lights also known as ‘rabbit lights’, mounted in the sea, directing the aircraft on a curved approach path to the landing threshold. Safeguards had to be in place such as two different electrical sources on alternative lights to prevent total failure. Closer to the touch down end, lights with limited beam width (to ensure accurate flying) were mounted on building roof tops as the final approach was low over these buildings. By law, no other flashing lights were allowed in the area. Not even for advertising thereby minimising the chances of pilots making mistakes. The lights were ‘on’ 24/7. There were two settings. High intensity during bad weather and day time and low intensity during night time.

I started flying into Kai Tak as a First Officer in the early eighties in the old Boeing 707 aircraft, which needed a lot of muscle to manually fly that critical approach to the runway, known as ‘Runway 13’. Then we graduated to the Lockheed Tri Stars, which made matters easier with a bigger flight deck with larger windows improving visibility on the final approach descending low level turn in excess of 40 degrees.

Finally, Air Lanka invested in ‘fly by wire’ Airbus A340 aircraft, which needed no muscle at all but the excitement was still the same which necessitated each flight crew member to adjourn to the toilet before the top of descent for a ‘nervous pee’. This happened every time all the time!  One day, soon after Air Lanka acquired the A340, I was required to operate an evening flight to Kai Tak. Due to the A340’s design, our crew had reduced to two (Captain and First Officer) in the flight deck from the previous three (Captain, First Officer and Second Officer/Flight Engineer). It was mainly to reduce the fixed costs of crew salaries. The S/O or F/E had a vital role to play besides operating the panel. He was an extra pair of eyes, when things got busy, vital actions wouldn’t be missed and mistakes not made.

After take-off from Bangkok we were told that a Director of Air Lanka and his wife were on board our flight. This officer and gentleman had a reputation of being a strict disciplinarian, a proud product of the Royal Air Force (RAF) College Cranwell, a former Royal Ceylon Air Force (RCyAF) Officer, and a Flight Instructor of some of my own Flight instructors in the SLAF. Having left the RCyAF, he had flown with the RAF. After retirement from the RAF he joined one of the many civil flying schools at Ratmalana as Chief Flight Instructor.

According to some of his students, although he was a very competent Flight Instructor, he ran a ‘tight ship’ and had a ‘short fuse’. Some students shivered in their boots. A definite ‘no-no’ in modern times. Being a close friend and neighbour of the then ‘Royal Family’ at Horagolla, he was later appointed a Director at Airport and Aviation Ltd Sri Lanka (AASL) and subsequently a Director at Air Lanka. The feedback I received by my own SLAF instructors and relatively junior Air Lanka First Officers who were trained by him, was that he didn’t shake hands and that his social behaviour was highly unpredictable. I had never met him but his reputation went ahead of him. It was an understatement to say that I was a bit apprehensive. I had heard that a few months before, when he was a Director at AASL he had chided one of his ex-colleagues for inviting his (the Director’s) wife to sit in the flight deck for the landing!

Anyway, courtesy demanded that at some point during the flight between Bangkok and Hong Kong, I had to make myself known as the Captain of the flight. What better time than the top of descent into Hong Kong when I would be going to the cabin to fulfil my ‘physiological’ need. After exchanging pleasantries, (I didn’t shake hands though) I invited him to sit in for the approach and landing which was always thrilling. He mentioned that he had flown into Hong Kong before in Bristol Britannia and Vickers VC 10 aircraft and requested that I permit his wife to do so. I was totally taken by surprise, but able to hide my reactions and agreed without hesitation.

The flight was uneventful until the latter part of the descent where we were informed by Hong Kong Control that the expected IGS for Runway 13 was unserviceable and instead they offered us an older, non-precision approach known as a ‘Visual Step Down’. Although neither my First Officer nor I had done such an approach before, we were carrying the necessary maps and charts that would allow us to safely carry out such an exercise. The French, UTA Douglas DC 8 pilots with whom Air Ceylon pilots flew used to say, “If you could read and understand English, then you can fly anywhere”. We could do the same (read and understand). The only problem was that the right turn to the final approach, after Stone Cutters Island, was almost 100 degrees in comparison to the regular IGS Approach which was only 47 degrees to the right. Both turns need to be done manually keeping the runway in sight.

The change of approach also meant a delay to all inbound traffic as adequate traffic separation had to be maintained. Now dusk turned to night. At last we were cleared for our self-briefed approach. Just as we got to the minimum descent altitude (it was a ‘gin’ clear night), we looked out and could see nothing familiar. Upendra, my First Officer, suggested dutifully that we should go-around. Then, it struck me that if I go slightly left I may catch a glimpse of the lead-in lights, which were flashing 24/7 in the harbour. Sure enough the lights were still on. I announced “Lead-in lights in sight” and continued with a sense of relief.

The approach speed of the ‘fly by wire’ A340 aircraft can be ‘selected’ by the pilot or ‘managed’ by the autopilot. On ‘selected’ mode the autopilot maintains any speed selected by the pilot in an airspeed window. On the other hand, the ‘managed speed’ automatically maintains an appropriate speed, depending on the flap setting. For that to happen we had to ‘activate the approach’ programmed through the Flight Management System (FMS) computers beforehand. I kept the autopilot on so that both pilots could search for visual cues to establish where we were. What the autopilot was doing was reflected exactly in our flight instruments. So, the plan was to take the autopilot off and continue to fly manually after visually establishing our position. The standard phraseology was “Autopilot off, speed managed”.

This time when the speed was managed it went up to 250 knots and the engines spooled up! We had forgotten to ‘activate our approach’ in the rush when our workload increased. If a third crew member had been there he would have probably reminded us to programme our FMS Computers well ahead of commencing the approach. Since it was too late to turn our heads in to programme them, I then did the next best thing possible and called for “selected speed and 140 knots” (our target approach speed), which was selected by First Officer Upendra and we proceeded to land. That saved the day and engine power returned to normal, ending up in a good approach and landing in the night. I am sure our lady guest in the Flight Deck was impressed.

Every flight has its own share of ‘Threats and Errors’. By definition Threats are external factors beyond the control of the crew and Errors are mistakes made from within by the crew members themselves either collectively or individually. An error could turn into a threat and vice versa. The task of the crew is to mitigate threats and trap the errors made to make it a safe flight. The International Air Transport Association (IATA) carries out regular Line Orientated Safety Audits (LOSA) on member airlines to ensure that these principles of air safety are met.

The Ramadan War

Published

on

Benjamin Netanyahu, Donald Trump and Mojtaba Khamenei

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

Published

on

“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.

Surath de Mel

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

Published

on

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.
