SLIIT should remain non-state and non-profit institution
By Professor R.P. Gunawardane
Sri Lanka Institute of Information Technology (SLIIT), one of the best and most popular non-state higher education institutions in this country, is in the news these days. It was established in 1998, with support from the Mahapola Trust Fund and its current status has been challenged by the Committee on Public Enterprises (COPE) of the Parliament of Sri Lanka.
Mahapola Trust Fund (MTF) was established by the late Minister Lalith Athulathmudali in 1981 to grant scholarships for needy undergraduates in the Sri Lankan university system. The Chairman of the MTF has always been the Chief Justice of the country. Nearly half a million of our deserving undergraduates have so far benefitted from the Mahapola Scholarship Scheme. The MTF is certainly a noble organisation, established for a noble purpose by a great visionary, the late Athulathmudali, who was one of the best politicians, and very intelligent and energetic Minister ever produced by this country.
The SLIIT offers a novel model of non-state and non-profit fee-levying university for Sri Lanka although such institutions are common in the developed world. All top universities in the world, including Harvard, Princeton, MIT, Stanford and all Ivy League universities in the US, and even Oxford, Cambridge and London universities, in the UK, are of this type. Although they receive some funding from the government for specific teaching and research projects, none of them are state controlled.
Almost all the top universities in the world are located in the USA, the UK, Europe, Australia and Canada. None of these countries have University Grants Commissions (UGCs) or equivalents, or Universities Acts to govern higher education institutions. All universities are completely independent and managed by their boards of management without any interference from the government. All appointments including the post of Vice-Chancellors are done independently, by the board of management. It is recognised all over the world that this type of independence is required for a university to carry out its duties and functions effectively, maintaining the highest standards.
History of SLIIT
Sri Lanka Institute of Information Technology (SLIIT) commenced its operations in 1999 as a non-state and non-profit higher education institution to train manpower in the field of Computer Science and particularly in the broad field of Information Technology. The development, with rapid expansion, was possible because of a strong commitment by MTF to provide a loan of Rs. 500 million and a lease of a land encompasing 25 acres in Malabe, owned by the Mahapola Trust Fund. However, only Rs. 373 million was released by MTF as a loan for this purpose.
It started functioning at the Bank of Ceylon Merchant Tower, Colombo 3, now called the Metropolitan Campus of the SLIIT. After almost 22 years of its existence and rapid development, it has now become a fully-fledged higher education institution at national university level with wide national and international recognition.
I served the Board of Management of the SLIIT for nearly four years at the initial stages from 2000. I was nominated to the Board of Management by then Minister of Education and Higher Education Richard Pathirana. I also served as a member of the Board of Governors of MTF in my capacity as the Secretary to the Ministry of Education and Higher Education.
During my tenure, I noticed the tremendous potential the SLIIT had in the higher education sector and the effort, dedication, commitment, perseverance and continuous hard work by a group of academics led by Professor Lalith Gamage to bring this institution to the present level. Whatever the mistakes made in the process of developing this institute, this achievement should be recognised and preserved. This institution should not be destroyed.
The SLIIT is a national asset that must be retained and further developed as a non-state sector institution with a framework for checks and balances with regard to the broad national policy.
Current Status of the Institute
Currently, the SLIIT has two campuses and four regional centres. The main campus with all the laboratory, library, auditorium and all other facilities is located on a 25-acre land in Malabe. Its Metropolitan Campus remains in the BoC Merchant building, Colombo 3. Its Regional Centres are spreading throughout the country in the major cities – Matara, Kandy, Kurunegala and Jaffna. About 12,000 students are enrolled in this institution with about 400 highly qualified academic staff and 200 administrative and supporting staff. It has a large number of links and joint degree programmes with prestigious universities in Australia, the US, the UK and Canada.
SLIIT, being a non-state non-profit institution, is not under the purview of the UGC, and does not have to abide the Universities Act No. 16 of 1978, which has centralised powers and decision making in the UGC. Thus, SLIIT has a tremendous advantage and full freedom to expand and diversify programmes with innovative approaches, without any clearance or approval from any authorities.
This freedom is lacking in the state universities, and as such clearances and approvals have to be obtained from the UGC and other relevant ministries and agencies to commence new programmes. In recent years, the UGC has taken over more powers outside the Universities Act with regard to introduction of new courses and novel projects requiring to obtain prior approval from the UGC. Sometimes, it takes up to one year or more to obtain necessary approvals or clearances. By the time approval is obtained the programme may be outdated or if it is a joint project with foreign university or international organisation, the other party is no longer interested.
This kind of freedom available to the SLIIT should be retained for further development and implementation of novel and innovative programmes. Our national universities do not have the kind of freedom currently available to SLIIT. That is why our universities cannot compete with other similar institutions in Sri Lanka and abroad although the state universities have sufficient expertise but with limited resources.
It is important to note that the SLIIT (1999) achieved the current status only in about 22 years of its existence while our oldest universities, Colombo (1942) and Peradeniya (1952), existed for about 70-80 years. It is remarkable that this institution has become a vibrant national university beating most of our state universities except perhaps a few universities like Peradeniya and Colombo.
SLIIT may be considered a new experiment and novel approach to higher education in Sri Lanka. Thus, this approach should be further explored for the expansion and diversification of higher education sector in Sri Lanka.
Issues and Concerns
SLIIT administration claims that the loan of Rs. 373 million obtained from the Mahapola Trust Fund (MTF) to establish the SLIIT has been fully paid with interest totalling Rs. 408 million. In addition, they also make the annual lease payment of Rs. 25 million for the land in Malabe regularly, as agreed. However, it should be noted that MTF is not a commercial bank or money lending institution and it does not give loans to others. It has not given loans to any other organisation. It is believed that the MTF at the time wanted to make a long-term investment in the field of higher education in line with the philosophy of its founder Lalith Athulathmudali. The intention would have been to generate additional funding to support the scholarship funding for rapidly increasing number of needy undergraduates. Thus, the support for the establishment of the SLIIT is an investment the MTF made for the future.
I consider the severing of SLIIT’s connection to the MTF is a grave and unforgivable mistake done by the SLIIT administration. SLIIT would not have come up to the present position within two decades if not for the original support of the MTF through a loan of a huge sum and a 60-year lease agreement for the land at a prime location in Malabe.
Furthermore, the refusal of the SLIIT management to appear before the COPE Committee is very unfortunate although they may not have to do so legally due to their current status. However, this act by the SLIIT which was created by a noble organisation such as the Mahapola Trust Fund is highly unethical and needs condemnation. It was also a missed opportunity for the SLIIT management to explain their side of the story to the COPE members in order to get some concessions.
Although they developed innovative and popular academic programmes, rapidly attracting a large number of students, there were a number of unresolved and troubling issues, within the Institute. Some of them are:
1. Insufficient emphasis on high quality research and lack of an initiative to develop a much-needed research culture in the institute are clearly seen.
2. In the past, there were some news reports pertaining to irregularities in the financial administration of the institute by some higher officials. The veracity of these complains cannot be ascertained until an investigation is done. It was reported that there was no properly qualified and experienced accountant or Bursar to handle financial matters, and there has been no internal audit for a long period of time.
Way Forward
It is essential that the SLIIT should not be taken over by the government. If it does, it will certainly do much more harm than good to the higher education sector. First of all, its connection to the Mahapola Trust Fund, which may be considered as the mother institution, must be fully restored. It is also necessary to reconstitute a fully independent Board of Management, consisting of highly qualified and eminent professionals with no history of any misdeeds. It also should include one representation of the Mahapola Trust Fund as well. This institution should continue to run as a non-state and non-profit higher education institution with the fee-levying status. Appointments at all the levels should be made by the Board of Management without any external or government involvement.
The matters raised above and any audit reports should be investigated thoroughly and appropriate action be taken in order to improve the image of the institution. As stated in the original agreement of the SLIIT with the MTF, and also as a gesture of goodwill, the SLIIT should pay 20% of its profit annually to the MTF to strengthen the Mahapola Scholarship Scheme. This should be done even if the MTF’s ownership of the Institute is not legally established. This is in addition to the annual lease payment to the Mahapola Trust Fund for its use of 25-acre land at Malabe, where its main campus is located.
Furthermore, SLIIT should establish a scholarship scheme by contributing sufficient funds to provide partial scholarships to needy students covering at least 10% of the total student population in the Institute. This aspect is extremely important for the survival of a non-state fee-levying institution in a country where state universities provide free education.
Restructuring the institute may also be required, avoiding unnecessary and irrelevant structures, units and subject areas and strengthening the teaching, research and consultancy functions in the core area of information technology. It is vital that the non-state and non-profit status of the SLIIT should be retained in order for this institution to develop rapidly to become one of the most prestigious higher education institutions in Asia, attracting a considerable number of foreign students. In this attempt, it would be the best for the SLIIT if Professor Lalith Gamage, the live-wire of this institution, who is mainly responsible for its tremendous success, should continue as the Vice-Chancellor/CEO for a longer period to see the best results.

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.
