Samadhi Statue, Guard-stones and Moonstones

Published

by ACB Pethiyagoda

This ‘Pilima Vahanse’ is said to belong to the Abeygiriya period of the third or fourth century of Sri Lanka’s history. It is not known in whose period of rule it was sculptured but is thought to be one of four similar statues facing the North, South, East and West – this faces North.

The statue was found in 1888, with the nose damaged, at the very site it is now in. Ravenhart in his “Ceylon – History in Stone” says that the repaired nose is over sharp and overlarge. Perhaps the repair was carried out by an ordinary mason who had no idea of proportions or aesthetics. This is not unusual, as there are many such instances of poor quality repairs in this country of damaged statues, stone carvings and particularly restoration of ancient temple paintings.

The Statue is 7’3″ in height, hewn from a single granite rock and said to have had two jewels for the eyes which are said to have gone missing in around 1914. The veracity of this is in question as the eves are closed with no place for jewels. The canopy over the statue was constructed in 1959/60.

Ananda Coomaraswamy wrote that the statue is “certainly the created work of art in Ceylon and is not surpassed in India”

Jawaharlal Nehru admired it when he first saw the statue in 1931. A year later, when he was in the Dehra Dun, jail a friend in Ceylon sent him a picture which he had with him in his cell and “it became a precious companion” he said.

Benjamin Rawland in his book “Art and Architecture of India” describes the statue as “The perfect embodiment of the idea of Samadhi (which) is conveyed through the very simplicity of conception; the perfect material equilibrium of the figure connotes the perfect mental state of the Sakyamuni through the massive stability of the triangular base formed by the inter locked legs mounted by the erect column body which supports the perfectly impassive mask like face.”

The Samadhi statue is symbolic of the tranquility of mind, with no attraction or repulsion from the world outside to disturb.

Guard-stones

The guard-stone or ‘doratupala/muragala’ at the top of the flight of steps which follow the moonstone leading to the Isurumuniya Rock temple was built by King Devanampiya Tissa in the Golden Age of Anuradhapura. It is one of the eight places (Atamasthana) of Buddhist worship in Anuradhapura.

The figure is of a Naga – a mythical human species closely associated with cobras whose function is to protect Buddhist temples from evil influences and to ensure peace, serenity, piety and prevent theft and sacrilege. Nagas carved on granite as guardians of places of worship built during the Anuradhapura period of Sri Lanka’s history are common. The workmanship is delicate and exquisite but bear a distinct Indian influence. In later times, such as the Polonnaruwa period the carvings are said to be inferior in quality and beauty.

The Nagas on guard stones are richly bejewelled, crowned and adorned with a halo of five or nine cobra hoods. This particular carving carries five such hoods. The chest is bare but the neck, ears, waist and ankles are decked in jewelry with a sword at the waist.

The figure is protected by three arches and in the Naga’s left hand is a vase of flowers while the right hand carries a sprig of flowers with a pot of flowers at its feet – all being symbols of prosperity. At the feet are also two Ganas or dwarfs who are believed to be attendants of Kuvera, the God of Wealth.

Moonstones

The Sinhala for the moonstone is ‘Sandakadapahana’ (sanda-moon, kanda-half, and pahana stone). It is a semi circular slab of hard granite, gneiss or limestone, depending on ready availability and is the first in a flight of steps leading to a Buddhist place of worship. These are richly decorated in concentric semi circular bands of low relief carvings of flowers, creepers, birds and animals. Many scholars regard moonstones as some of the finest examples of the ancient Sinhalese artists, which is the reason for reference to them in the Mahavamsa itself.

The moonstone is also called Irahandagala’; (ira-sun, handa-moon, gala-stone) in Sinhala. The sun comes into the word because from the earliest of times very many cultures of the world venerated the sun as giver of life, fertility and growth. The ancient Sinhala people were no different as the sun was given a predominant place in their poetry, paintings, sculpture, flags, etc.

Its importance is such that their main cultural and social celebration, the Sinhala New Year, around the April 14 each year, is related to positions of the sun. Thus the significant position of the lotus flower in the moonstone emphasizes the importance of the sun to life itself and is symbolized by the flower which blooms with the rising sun and stays open only so long as it shines.

The moonstone is therefore considered to have beneficial magical powers which ensures prosperity when people came in physical contact with it even by merely stepping on it. The moonstone was the first step to the entrance of the then temple of the Sacred Tooth Relic at Anuradhapura and is described as a classic example of the “best of the class of the decorated type of moonstone…..”

The protective wrought iron fence erected round it in recent times, does not unfortunately allow a picture to be taken in bright sunlight without its shadow falling on some part of the subject at most times of the day unless taken from a considerable height, requiring specialized equipment or perhaps under conditions of overcast skies.

The centre panel of this moonstone consists of two rows of lotus petals followed by a row of geese between two rows of a creeper followed by a panel consisting of elephants, horses, lions and bulls. The outermost semi circle depicts flames of fire.

S. Paranavitana in his “Significance of the Sinhalese Moonstone” explained as follows the significance of each carved panel which according to him represents a spiritual stage in a human’s ascent to Nirvana.

“i. the arc of flower petals (palapethi) motif; the fires of worldly existence.

ii. the arc of four beasts – elephant, lion, horse and bull : the four mortal perils birth, disease, decay and death

the arc of undulating scrolls of leaves and flowers forming the liyavel piyaveli motif; desire or craving (tanha)

iii. the arc of swans or geese (hansa): the thoughtful ones who have left their worldly abodes.

the arc containing a second liyavela motif: the heavenly worlds.

iv. the arc of lotus petals turned outwards, the arc of lotus petals turned inwards and seed-cup in the centre forming together half a lotus: Nirvana.”

All moonstones do not follow this decorative arrangements as some have a panel or two more indicating that the ancient sculptors enjoyed a great deal of freedom in the expression of their art. Some are even more than a semi circle in shape while in others the innermost panel with the lotus flower are raised and are at a higher level than the other panels. Some moonstones of the later part of the Polonnaruwa period are devoid of the bull as in those times the influence of Hinduism was significant and stepping on a figure of the bull was considered sacrilegious as the cow is sacred to Hindus.

Paranvitana saw a “deep metaphysical interpretation” in the panels while D.T. Devendra thought the moonstone was a mere decorated doormat. While the choice between the two very divergent views is the reader’s, only the ancient sculptors themselves knew the reason for their labours. Some of them could have been inspired by great religious fervour while others may have carried out the task purely for material rewards. On the other hand it could have even been a mix of both. We would never know for certain.

V. Vitharana in his essay, “The Moonstone and its Fertility Associations” supports Paranavitana’s interpretation and goes further to say that moonstones are so numerous in Sri Lanka that even an approximation of the numbers is difficult to make. With excavations going on more are likely to add to these numbers.

The origin of the moonstone is traced to the time of the Buddha. It is said that the floors of the Pabbarama monastery in Savarthi built by the wealthy devotee, Visakha, were covered entirely with rich and rare cloth before she offered it to the Lord. Another wealthy lady who also wished to offer such a cloth could however not find a place to lay it on.

Ananda Thero seeing the lady’s disappointment advised her to place her offering at the foot of the stairway leading to the building where the Buddha and monks in attendance would step on after their feet were washed at the entrance to the building. This was done and since that time the first step at the entrance to places of Buddhist worship began to be beautified in various ways and in due course with stones decorated with carvings. At first the carvings were very simple and as time went on these became more elaborate resulting in the moonstones seen today.

Hence, the origin of the moonstone was in India and was later introduced to Sri Lanka with the advent of Buddhism. C. Godakumbura in his book ‘Moonstones’ describes a few seen in Andhra, Sanchi, Ajanta and Elora and goes on to say that some of those were partly decorated while others were carved fully but all these had a connection with Buddhist places of worship. Later on even entrances to palaces came to be adorned with moonstones.

Among the hundreds of moonstones available in Sri Lanka, a few of the most outstanding in beauty and technical perfection are said to be the ones described above and those at Mahasena’s pavilion in the Abayagiri area, in the premises of the Sri Maha Bodhi in Anuradhapura and the Vatadage in Polonnaruwa.

The moonstone at the entrance to the Sri Dalada Maligawa in Kandy was of exquisite beauty and perfection but was marred by the LTTE terrorists when they attacked the temple.

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.
