Plantation sector and economy

Published

By Dr. C. S. Weeraratna (csweera@sltnet.lk)

Sri Lanka is facing an unprecedented crisis mainly due to economic mismanagement and corruption in the various development sectors. During the last few weeks, at various discussions related to the country’s economy, the need to take effective action on the present economic situation in the country has been highlighted. President Ranil Wickremesinghe stressed the need for all sections of the government to act unitedly to take the nation towards stability by the end of the year. But there appear to be no plans to get the country out of the doldrums.

The need to increase our export earnings to meet the severe financial crisis we are facing today has been emphasised by many but there appears to be no plan to achieve that objective.

Increase export earnings

Increasing exports is of paramount importance to improve the present Foreign Exchange (FE) crisis. A major source of FE is the plantation sector. Around 800,000 ha in the country are cultivated with plantation crops tea, rubber, coconut etc. and this sector, in the last few years earned nearly Rs. 360 billion annually. However, as indicated in table 1, production of these major export crops do not show any substantial increase during the last six years.

As shown in Table 1, tea production has been fluctuating around 300 million kg per year during the last five years, in spite of several institutions assigned to the tea sector. The average tea yields are considerably lower than the potential yields. In the smallholder tea sector the average yield is around 1800 kg/ha and in the estate sector it is about 1200 kg/ha. In 2020 tea earned Rs. 230 billion in FE. Better management practices in the short term would increase the quantity and quality of the tea produced making it possible to increase FE earnings substantially from the current Rs. 230 billion.

Rubber is another important export crop. In 2017 it earned nearly Rs. 6 billion in foreign exchange but has decreased during the following three years. Based on Central Bank annual reports, the total rubber production in 2016 was 79.1 million Kg and by 2021 it has plummeted to 76.9 million kg. The corresponding average yields are 819 kg/ha and 679 kg/ ha respectively. These figures indicate that the Sri Lankan rubber sector is ailing in spite of several institutions such as Rubber Development Dep. and Rubber Research Inst. assigned to promote rubber production in the country. With the current high rubber prices it would be possible to earn more FE by increasing rubber production by better management practices which would produce results in the short term. During the last few years the rubber sector has been affected by many factors one of which is ineffective management.

Coconut production too has declined during the last five years as shown in Table 1. The total extent under coconut in Sri Lanka is around 400,000 ha and about 325,000 ha are small holdings. Annual production of coconut has been fluctuating around 3,000 million nuts, If the production of the existing coconut lands is increased by 1000 nuts/ha/year by better management, and applying organic and inorganic fertilisers the total production can be increased by a substantial number within a year which will increase the export income from coconut.

Sugar production in the country has not increased by any appreciable amounts during the last few years as sown in Table 1 in spite of three sugar companies, Pelwatta, Sevanagala and Hingurana and the Sugarcane Research Institute. Kanthale sugar factory remains closed over a long period, while a plan to cultivate sugarcane in Bibile remains shelved. There are crops such as coconut, kitul and palmyrah which can be used to manufacture sugar based substances such as jaggery and treacle, but there appears to be no effective strategy to promote the production of sugar and sugar based substances in the country

Sri Lanka, a country begging for dollar loans to import medicine, fuel etc, which are critically important, need to have an effective plan on exports. A large number of crops other than tea, rubber and coconut cultivated in Sri Lanka have a high potential as export crops. There are 24 agro ecological zones, each characterized by specific climate and soils. This makes it possible the cultivation of different types of crops such as spice crops, tuberous crops, horticultural (fruit crops) and floricultural crops, medicinal herbs etc.

In view of the present deteriorating economic situation on the country, strategies need to be implemented to increase production from the plantation sector and hence FE earnings. There are many state sector organizations such as Tea Board, Rubber Development Dep, Coconut Cultivation Board etc. to implement such strategies.

A number of issues can be attributed to the present unsatisfactory state in the plantation sector. Among these are (a) Increasing cost of production ( b) Old machinery (c) Land degradation (d) Old age of crops (e) Low value addition (f) Inadequate diversification and intercropping and (g) Insufficient marketing strategies

Land Degradation:

One of the important contributory factors for the decline in the productivity of the plantation sector is Land Degradation. Soil erosion, soil compaction, and nutrition depletion, cause productivity of land to decline, making crop production less profitable. In view of the importance of land degradation, the Ministry of Environment, in 2005, established an expert committee on Land Degradation. This committee comprised a number of experts in the field of land management and the main role of the committee was to advice the Ministry of Environment, on issues related to controlling land degradation. This committee has not met since Feb. 2013.

At the first national symposium on Land Degradation held in 2010 , organized by the Ministry of Environment and the expert committee on Land Degradation, the participants, who were representing many land-related institutions in the country, revealed that a substantial amount of soil/ha/year is lost due to soil erosion. They were of the view that urgent action such as implementation of proper land use planning and the soil conservation and environment act etc. need to be taken by the relevant organisations to control land degradation.

There are many ministries, departments and other institutions which are expected to take appropriate measures to control land degradation. During the last few years a large number of seminars, workshop s have been held on this topic. In spite of all these, land degradation continues to take place evident by the common occurrence of landslides, depleted top soil, siltation of tanks and reservoirs, decline in crop yields, etc. The Ministry of Environment (ME) needs to activate the already established Committee on Land Degradation which would make appropriate recommendations to reduce land degradation to be implemented by ME. A land use policy has been formulated but is not effectively implemented to reduce land degradation which has serious repercussions on the productivity. The Land use policy need to be implemented as an integrated programme in increasing the productivity of the plantation sector.

Diversification:

Productivity of many estates under plantation crops is at a low level. Diversification of such unproductive lands is essential. A survey need to be done to identify these unproductive lands which need to be diversified.

Such lands may be put under pasture and have cattle which will reduce our expenditure on milk imports. it will also reduce degradation of the lands resulting in less silting of the reservoirs. There are many other crops such as spice crops, floricultural and horticultural crops etc. which could be cultivated in the unproductive lands. Among the horticultural crops, cashew has a considerable potential in increasing exports. These crops would give better returns to the cultivators. Hence, an in-depth study needs to be carried out as early as possible to determine appropriate land use in the unproductive holdings/estates giving due consideration to factors such as climate, topography, availability of labour etc. Those lands which are not going to be diversified need to be managed better. In this regard, infilling, cultivation of better clones and their effective management including better fertiliser and pest management practices, , increased rate of replanting, reducing soil degradation and conservation practices are essential.

Deterioration of the plantation sector will exacerbate the financial and social problems we are facing.. The annual trade deficit which stands at around Rs. 1,800 billion and unemployment among the rural plantation community will get worse. In view of these critical issues faced by the Plantation Sector it is necessary that the relevant authorities lead by the Ministry of Plantation Industries develop a holistic national plan to resurrect the plantation industry .

It is also important that the respective ministers get the service of scientists in managing the relevant scientific organisations under them.. For example, during the last few years the Rubber sector which plays a very important role in the economy of the country was headed by personnel who have little or no experience in the rubber sector.. A few years ago an “expert” was appointed to the ministry of Plantation Crops who came out with an unrealistic Rubber Master Plan which would cost the country Rs. 75 billion. Such appointments surely will not enable the respective institutions to contribute positively to the areas which they are expected to develop.

Promoting agro-industries will have a considerable positive impact on increasing exports. There is an urgent need to develop agro-industries in Sri Lanka, which will have a tremendous impact on unemployment and rural poverty. A large number of crops cultivated in Sri Lanka, including rice have considerable potential in various agro-industries. However only rubber, coconut and a few fruit crops are used in industries. Crops such as cassava, horticultural and floricultural crops, medicinal herbs, cane, bamboo, sunflower, castor , ayurvedic herbs, etc. have a considerable industrial potential but are not cultivated. cardamoms, nutmeg, mace and vanilla which grow in abundance mainly in the wet and intermediate zone,. In 2020 county earned nearly Rs.60 billion by exporting spice crops.

Spice crops have a high potential to increase FE earnings. Cinnamon is the most important spice commodity among the spice sector. The production of cinnamon has been fluctuating around 20,000 t per year during the last few years. Pepper is the second important commodity among spices .It is grown in the wet and intermediate zones mostly as a mixed crop. The Sri Lankan Pepper has higher piperine content which gives it a superior quality and pungency. Annual production of pepper too has remained stagnant at around 20,000 kg. Other spices such as cloves, cardamom, nutmeg and mace have the potential to earn a substantial amount of FE. With the increase of international demand for natural products, and the island’s focus on enhancing and evolving its value added range, spices and the essential oils extracted from these crops will continue to earn more FE.

Dehydrated food is another agricultural product which has a potential to earn much wanted FE. During some months there is a glut of fruits and exporting dehydrated/canned fruits would bring in an appreciable amount of FE. Private sector can be involved in such projects for which appropriate technical assistance need to be given by the relevant public organizations

Although hundreds of research projects related to plantation crops are carried out by the Faculties of Agriculture , Research Institutes etc. there appears to be no organized system to utilise the research findings in our efforts to increase productivity in the plantation sector. There is very little liaison/interaction among the relevant institutions, and the research carried out in the country appears to have no appreciable positive impact on the plantation sector in the country. .In a developing country such as Sri Lanka, a primary objective of scientific research must be to utilize locally available resources. Research priorities, need to be based on the needs and problems in the production sectors.

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.
