Mess in energy sector
By Eng. Parakrama Jayasinghe
parajayasinghe@gmail.com
Over the years, I have published articles, originally addressing particular segments of the energy sector, in the hope of some sanity emerging in the sector in the broader interest of the consumers and Sri Lanka in general. But, of late, I have tried to focus on the entire sector, which is vital to the national interest by the very nature of the Sri Lankan energy scene and its ramifications that are unfolding. A major flaw in the thinking and actions of the energy authorities is their inability to understand that the Energy Sector is not limited to Electricity, but spans a much wider scope. Focusing on individual segments is a recipe for disaster, which has been proven more than once and are staring in our faces right now.
A few of these articles are listed below, which is only a small fraction of all I have published:
CEB wants to be a follower of old technology – August 2018
Losses due to blockage of RE Projects
– February 2020
The Origin and Way out of the Energy Crisis
– April 2019
The Sri Lankan Energy Sector – A Mill Stone –
August 2023
The focus on particular aspects individually, which is the present practice, is not logical for a visionary and sustainable development and maintenance of this vital sector of the economy. The responsibility of the two major sectors of Electricity and Petroleum being under a single Minister has not yielded the desired outcome.
I feel obliged to provide some justification for the events that led to my conclusion and the validity of my title for this article, to pre-empt the loud objections that are bound to be levelled against me, by those whose noses would burn in recognizing their culpability of taking Sri Lanka to this abyss.
A cost reflective electricity tariff?
The massive hike in consumer tariff in February 2023 was the most socially-insensitive proposal. Fortunately, it was corrected somewhat in the July revision. But everyone is apprehensive about what will happen in January 2024. This massive hike, touted as a cost-reflective tariff, obviously at the behest of the IMF, was supposed to be an essential adjustment to make CEB financially independent of the annual rescue moves by the Treasury (read rescue by the consumers, who have been carrying this burden indirectly year after year). But did this happen?
We see news reports on the CEB demanding further tariff hikes immediately, purportedly to avert losses for the current year, too, amounting to 50 Billion rupees or more. So, who will be held responsible and accountable for this highway robbery?
The answer is obvious, judging by the past practices. Who should be held responsible for running up a financial deficit of near a trillion rupees over the past decade, all of which were passed on to the public with no one held accountable or made to feel any slightest pain of their own?
Continued dependence on Emergency Power
One may think the need for dependence on expensive emergency power occurs only in case of emergencies. But whoever heard of adding emergency power as a component of future energy plans? What price the least-cost option being the primary principle of the 20-year-long-term generation plan? If that is the only solution that can be offered by the planners or the designers, they lack competence to continue to serve in such positions. Even more damaging is the fact that those who are supposed to govern the sector, both at the CEB and at the Ministry, accept such retrogressive and damaging solutions to meet the national electricity demand, which is predicted many years in advance. A substantial amount of emergency power, at highly enhanced cost, has been approved by the Cabinet and even by the PUCSL for the year 2024 already. Obviously, no one is demanding nor the CEB is offering any viable alternative. The easy solution has been to pass the burden of the added cost on to the public, as has been done for years in the past. Uninterrupted supply of electricity 24/7 irrespective of cost?
The unprecedented power crisis in early 2022 made Sri Lankans realise the dangers of over dependence on imported resources for energy. The two major streams of energy demand ground to a halt for want of foreign exchange to pay for imports. In parallel, even the kitchen fires went out due to lack of LPG. Everyone had to accept the many hours of power cuts and long queues for fuel. The efforts of the government to mitigate the crisis must be appreciated. But the consumers are burdened with tariff hikes as the price.
However, the role of any responsible government and those in authority on the entire energy sector, regardless of which Ministry they serve under, should be much more visionary and proactive, at least to minimize this danger in the short term and then eliminate it entirely in the medium term.
The developments in the energy sector, worldwide, and the much-delayed recognition of the bounty that mother nature has bestowed on Sri Lanka, should have been the greatest incentive for this process to be expedited. The fact that on some days Sri Lanka was powered with zero dependence on oil-based generation and much-reduced use of coal as well as the drain on exchange for import of transport fuels saw a significant reduction was the best driver for a government with the longer term interests of the country at heart to initiate and follow that path. The people would have come to terms with a two-and-a-half-hour power cut and the rationing of fuel longer if they had been convinced that there was plan to achieve energy security. (See figure 1)
However, the Ministry of Power and Energy, or the state institutions under it, does not seem to have recognised this as their responsibility or has chosen to ignore it entirely. Instead, its actions appear to be driven purely by a political agenda. The present practice of ensuring an uninterrupted electricity supply by using the most expensive option of oil-based power, and removing all controls on supply of transport fuels with no consideration of costs, both in rupees and even more prodigal expenditure of dollars that we don’t have, is deplorable.
The public is to face a heavier burden, going by the media reports appearing, which predicts a loss of over Rs 50 Billion for the CEB, in 2023, in spite of the massive hike in consumer tariff. The increase in the country’s foreign debt due to this kind of expenditure is not yet known.
Is Sri Lanka helpless?
In spite of the many problems and difficulties, one area where Sri Lanka has been endowed with ample resources is energy. While issues of costs and lack of funds and technologies prevented harnessing this bounty in the past, the circumstances have changed in our favour during the past decade or so. While some enterprising individuals and companies came to the forefront and practically demonstrated this viability, several state organisations with monopoly rights and the lack of governance by the Ministries and the government have landed Sri Lanka’s energy sector in the present sorry state. It is being claimed in some quarters that Sri Lanka cannot raise the funds for renewable energy projects and does not have the technical capability to develop them. But this is an untruth aimed at bringing in foreign entities to the sector. Even a 100 MW solar plant consists of about 175,000 of individual solar panels, a pair of panels with capacity 1 kW being viable as a unit. There is absolutely no reason to lump them together to capacities over say 10 MW just to shut out the local entrepreneurs and technology companies and add the long transmission lines as an added infrastructure requiring more investments by the state. In case of wind power, the unit size has grown up to about 5.0 MW only. The success of the Suryabala Sangramaya, which has already led to the development of over 700 MW of solar energy to the grid is a case in point. That source alone could provide 5,000 MW of generation capacity and 7,000 GWh of energy to the national grid, if the CEB takes it upon themselves to champion it rather than finding excuses to deter the potential “prosumers”. ([RJ4])
There is a need to attract foreign investments and tap the many green funds already available. But these must be done on our terms. Any attempt to pay dollars for the supply of electricity for our consumption cannot be accepted under any circumstances.
Are we to buy our solar energy with dollars?
It is feared that this is what may have been agreed with the Indian investor for the project in Mannar and Purnaryn, the agreements on it being totally in violation of the provisions of the Electricity Act. But all state officials are bending over backwards to help this company; they are even obstructing the processing of projects nearby by local developers.
(Sri Lankan energy sector as millstone around nation’s neck
https://island.lk/sri-lankan-energy-sector-as-millstone-around-nations-neck/)
These resources are sufficient to meet our renewable energy needs forever and earn foreign exchange. The much-talked about power link to India is technically and financially viable, provided it is designed and executed to meet Sri Lanka’s interests and not as part of the ongoing privatization programme. The government’s move to hand over large tracts of lands to foreigners cannot be accepted under any circumstances.
Under these bleak conditions the award of the 100 MW solar project in Siyambalanduwa to two local companies provides a ray of hope. As we proposed some time ago, it should have been a 4 x 25 MW system, which could have been funded locally.
It is time Sri Lankans insisted that the energy sector remain an indigenous industry geared to develop its own indigenous renewable resources so as to ensure long-term national energy security and also to be a major driver of economic growth. Our capability to do so has already been proven. (See Figure 2)
It is the duty of all chambers of commerce and industrial associations and most importantly for the media to highlight this without delay, before our resources are handed over to foreigners just for the benefit of the few individuals or companies.
The recent court ruling on the Solar Project in Vavuniya exposes the mismanagement and misuse of powers by the two state institutions mandated to develop the sector, rather than obstructing it. The company concerned deserves praise for its perseverance and eventual success of the legal battle.
One may also recall that the CEB has blocked the development of all renewable energy projects from 2016, citing a lacuna in the Electricity Act of 2009, amended in 2013. This did not deter them from allowing the Indian company to develop 500 MW wind and solar without any tender procedures.
Let us hope that the above judgement and some favourable changes seen in the management hierarchy of the CEB would lead to the much-desired paradigm shift in the mindset and actions of those mandated to serve the country and not individual interests.
Conclusion
We have ample indigenous renewable energy resources to meet all our energy needs, and surplus can be used to earn foreign exchange.
At a recent public lecture, the newly appointed General Manager of CEB, presented the essential elements that should be observed in a proper Energy Market…
Freedom of Choice
Economic Efficiency
Social Equity
Transparency
We hope that he will have the courage and strength to ensure that these principles are adopted in the CEB that he now heads.
I have confined my comments to the electricity sector. The bigger culprit, which is the transport energy, needs a separate analysis. Meanwhile, the readers are requested to refer my previous below.

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.
