Non-aquatic birds and return to Thittawella
by Athula Dissanayake
(Continued from last week)
As I sat, small flocks of Indian crested tree swifts would fly to and fro overhead, uttering loud calls, “keek-ko, keek-ko…” as they hunted their insect prey. During the migrant season flocks of Eastern swallows descended on the tank skimming the surface as they flew gracefully, twisting and turning, while hunting insects. In the large trees bordering the tank I would occasionally catch a glimpse of a pair of the rare and magnificent black-backed yellow woodpecker, the largest of its tribe.
A common kingfisher would dart along the shore, uttering its shrill call. It would perch on a small rock that stood in the water and wait, sometimes bobbing its head and jerking its body and tail excitedly. On spotting a fish it would dive headlong into the water and return to the rock empty handed while uttering a loud “cheek, cheek, cheek” to voice its disappointment. After several attempts it would return to the perch with a silvery fish dangling in its bill, thump it on the rock a few times and then swallow it head first.

Its more terrestrial cousin, the white breasted kingfisher revealed its presence by its loud cascading call from a nearby tree. Largest of its kind, the gorgeous stork-billed kingfisher frequented the trees bordering the nearby stream, where it used to fish in the dappled sunlight.
Activity in daytime
In the morning the birds were active while feeding, walking and flying to different parts of the tank. As the morning wore off all activity gradually dwindled and by midday it came to a stop. As the birds rested in the midday heat, everything was still and quiet, and hardly a bird could be seen as it took shelter among the water plants. A gentle breeze stirred a few ripples in the water and swayed the floating lotus leaves. Occasionally a bird would preen or take a bath by splashing in the water.
A sleepy atmosphere prevailed, enhanced by the constant drone of the cicadas. A gentle popping sound would indicate a surfacing fish or a sudden splash would indicate one jumping out of water to avoid an underwater predator. The silence would at times be rudely broken by the loud ringing calls of a pair of serpent eagles soaring in the heavens on thermal currents.
Towards evening the activity became more pronounced and the teals, coots and jacanas came out into the open to feed. The tranquillity was broken by a chorus of calls emanating from aquatic birds resting among reeds and lotuses. The tank was particularly noisy during the breeding season, when it was full of water and the vegetation luxuriant.
Coots and jacanas were the noisiest of the lot. They could be seen running and chasing rivals and engaging in mock fights.. A pair of white breasted waterhens added to the chorus with their loud call “kapparakata puwak puwak” as they prepared to roost in a clump of bushes at the water’s edge.
As the evening gave way to dusk, the chorus gradually died down and silence reigned once more.
A purple heron, silhouetted against the setting sun, flew to its roosting place. Its rise and fall with each beat of the wings, was a most serene sight as we stood on the bund. It was a peaceful scene after most of the birds retired for the night and creatures of darkness gradually and silently took over.
Night herons, with their attractive white and blue-grey plumage and a ruby-red eye, took up their posts by the water’s edge as they prepared for a stint of night fishing. The silence was interrupted by whistling teal as they circled the tank, uttering their shrill calls before flying off into distant paddy fields for their nightly forage. A red-wattled lapwing would announce its annoyance at the presence of a predator by its piercing call “did you do it”.
Breeding season
All the birds looked their best during the breeding season, particularly the males who wore their bright nuptial plumage, such as the jacanas with jet black bellies and long tails, grebes with chestnut in the neck, cotton teals with glossy green on their backs, and pond herons and egrets with long streamers down the neck. A korawaka or white-breasted waterhen swimming among the lily pads, with its brood of fluffy black chicks, offered a most pleasing sight.
Once I saw a male coot climbing the back of a larger female in attempting to mate. Unable to bear the weight of both of them, the floating vegetation gave way and the couple sank in the water. It was quite a hilarious episode. The affair was promptly abandoned as they went about their different ways. However, I saw them making a successful attempt later in the evening.

15 years later
All things change with time. My two cousins grew up and went their different ways. I entered medical college to engage in a busy career and our visits to the Thittawella tank stopped abruptly. Thittawella receded deep into the past. It was 15 years later that I came to reside in Kurunegala again when I was posted there.
At Kurunegala, I found a partner and friend in Dr. R. Thalgahagoda, Consultant Rheumatologist, who was also interested in wildlife. I wasted no time in organizing a trip to Thittawella tank in an evening and soon found myself seated on a rock close to the bund accompanied by him. As I sat there after so many years, all those memories came flooding back, and it was intensely nostalgic. Birds were still there, and I was able to observe them even more closely with the aid of my new equipment, namely a small telescope. It brought out the beauty of the tank birds more vividly. Thus began phase two of my acquaintance with Thittawella tank.
One day Thal and I were seated as usual on the tank bund, relaxed and leisurely watching the abundant bird life around us. Dusk was approaching and a three-quarter moon rising in the sky above the hills in the east. A flock of whistling teal rose from the tank and flew up into the sky. It was the largest flock of whistling teal I have seen so far. They then kept on flying round and round the tank, calling incessantly for several minutes. As the dusk advanced and the moon rose higher, flooding the tank with a mellow silvery light, they kept on circling and whistling what sounded as sweet music to our ears as we watched them enthralled. That is a spectacle I would never forget.
Uncommon birds
With the aid of the telescope, I spotted one day a pair of birds I had missed in my boyhood. They were Indian waterhens or common moorhen walking on the lotus leaves. It was a beautiful bird, black in colour, with a yellow-tipped bill, a bright red shield on the forehead, and yellow legs. A white line ran along the flank, and the under-tail coverts were also white, contrasting with the glossy black of the rest of the plumage. While walking they frequently jerked the tail up. At times they would get into the water and swim like ducks and it was quite interesting observing their antics.
In the dry season, a considerable part of the tank bed is exposed. During such a time one evening we observed a few birds feeding quietly on the muddy surface, close to some bushes. They had a prominent white ring round the eye, which merged into a short strip just behind. The belly was white, the throat a rich chestnut brown and the back olive brown. They were probing the mud with their longish bills, which were slightly curved downwards.
We watched excitedly as we got our first sighting of an uncommon and rarely seen bird, the painted snipe. It was surprising to see such a shy and skulking bird feeding there out in the open, in full view of us for a long period of time. Meeting the unexpected is one of the joys of bird watching. In contrast to the normal pattern of birds, the female of this species is more distinctive and brighter in colour than the drab male. This is in keeping with their reversed role in domestic affairs as the male is encumbered with the duties of incubation and tending the young.
We also saw a solitary snipe, most probably a pintail snipe, walking along the margin of a puddle probing the mud with its long slender bill. It was quite undisturbed by our presence, and this was again unusual for a shy bird.
One evening, when we were seated on the bund of the tank, we were presented with a rare gem. A small quail-sized, rounded bird appeared from the edge of a reed bed and started walking briskly on its greenish yellow legs on the lotus leaves. It jerked the short tail as it went along. The under parts were barred blackish and white (as in most of its other relatives) and the upper parts were a yellowish brown, speckled and streaked with white. It was very actively catching insects as it walked. At times it darted a couple of feet up into the air, in the manner of a flycatcher, and landed back on the lotus leaves.

We watched it in good light at close range for about half an hour before it disappeared among the reeds. We took down all the details of its plumage and were in no doubt regarding its identity, namely a Baillon’s crake. In his Guide to the birds of Ceylon, G M Henry mentions that ” this small crake has been recorded from Sri Lanka only a few occasions in the last hundred years.” So we were absolutely delighted to have seen such a rare bird. As I stated earlier, one of the great joys of bird watching is that the most unexpected bird may be met with at the most unexpected place.
Another rare sighting we had was a Shahin falcon. It was flying above the tank towards Elephant Rock in the distance, where we later saw it on a number of occasions.
Finale
In 1995, I was transferred to Teaching Hospital at Karapitiya in Galle, while Thal was posted to General Hospital, Kandy. Both my cousins, who initially accompanied me to Thittawella tank, took to hotel business. Prasanna, the elder of the two, when working as an executive in a hotel at Kandalama near Dambulla, was in 1999 drowned along with six others, when a boat in which they were on a joy ride on Kandalama tank capsized. Nagitha now runs his own restaurant in Sydney.

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.
