Thilo Hoffmann’s contribution towards improving and creating protected areas
Excerpted from the authorized biography of Thilo Hoffmann by Douglas. B. Ranasinghe
Set out below is an account of Thilo Hoffmann’s other work in nature conservation site by site. Further details about his involvement in some of these sites and yet others are found elsewhere in this book.
1) Wilpattu National Park
When the important Western section of Wilpattu had only the status of Sanctuary, and it was even proposed that there should be a public road across it, Thilo intervened on behalf of the WNPS and persuaded the government to make it part of the Wilpattu National Park.
The two Intermediate Zones to the South and East were incorporated in the Park at his suggestion. It was an important consolidation, as the Wilpattu East IZ occupied a major portion of the present Park.
He proposed, as also described in the last Chapter, a further extension to the Park as a Marine Sanctuary. This proposal, too, was supported by ample documentation prepared by him.In recognition of Hoffmann’s contribution to the cause of conservation of nature and wildlife in Sri Lanka, the Talawila bungalow at Wilpattu was named after him by the Ministry of State in 1985. On this occasion two conservationists were honoured in this manner, the other being Dr. RL Spittel.
2) The South-East Complex
On Hoffmann’s suggestion all the Intermediate Zones in the country were incorporated into National Parks. Thus the land in the Yala complex with that status was made part of the Yala, now Ruhunu, National Park. He also proposed extending the Park into the ocean to include the Basses ridge and reefs.
As the President of WNPS Thilo was pleased when the Society was invited on two occasions to participate in discussions at the Ministry of Irrigation, Power and Highways on the Heda Oya Project and the development of the Lower Uva area. He pointed out that, if implemented, the projects would have a very considerable impact on exiting and proposed conservation areas, notably the entire Yala complex, the Lahugala-Kitulana Sanctuary and also the very important Bundala Sanctuary, the two last named now National Park.
In 1977 Thilo gave his view on this project in an article to Loris under the title ‘Major Threat to the Oldest Wildlife Reserve’. He brought to the notice of technocrats and administrators that National Parks and other National Reserves are areas sacrosanct by definition and law, which cannot be altered and changed at will, that it is only the National State Assembly which can decree and approve boundary alterations in these.
Further, he strongly argued that buffer zones of natural forest or of plantation forest should be established and maintained in lieu of Intermediate Zones when the latter were incorporated in the National Parks. His opposition to the construction of hotels on the Yala coast is also set out together with his comments on visitor pressure at the Ruhunu National Parkrk’, below.
The Lahugala-Kitulana National Park of 1,550 hectares was declared on October 31, 1980 especially for the protection of elephants, and the Bundala National Park of 6,216 hectares was declared on October 15, 1990 mainly for waterbirds. The earlier planned development projects were abandoned.The Bundala National Park was named Sri Lanka’s first Ramsar Site in 1991. Thilo’s role in this, and the declaration of other Ramsar Sites, is also recorded in this book.
The Gal Oya National Park, of 25,900 hectares, was established on December 12, 1954 by the Gal Oya Development Board for the protection of the new reservoir, the Senanayake Samudraya, and was handed over to the Department of Wildlife in 1965. It lies in the dry zone low country, and is part of the Uva Province. The basic concept of the Park was to provide at least a small, fully protected catchment and protective area for the reservoir – whose total catchment is much larger.
Thilo made several visits, and reported to the authorities on shortcomings and the improvements that could be made. In April 1973 – just after climbing Ritigala Peak and despite a painful back injury, a slipped disc – Thilo spent four days in this National Park, sleeping in the open and walking long distances in the company of several officers of the Wildlife Department, in order to obtain a clear picture of the conditions in the Park at that time.
It contains the greatest extents of talawas with mana grass and the fire resistant aralu, bulu, nelli and gammalu (Pterocarpus marsupium) trees and madu. Hoffmann published a summary of the report on this visit in Loris, titled ‘The Gal-Oya National Park. His ideas, in brief, were:
1. This is the most beautiful and attractive National Park. The combination of its wildlife, notably elephants and birds, the special flora and the impressive landscape makes it ideal for visitors, including foreign tourists. The potential of the Park was great and basic access relatively easy with almost daily flights to and from Ampara. Opening it for visitors should be the first priority of the Department.
2. The boundaries of the Park should be altered with the inclusion of a few square miles of additional land, notably along the Western flank. The most important corrections suggested were those concerning the inclusion of the ‘Nilgala wedge’, the Pallang Oya Reservoir (now called Jayanthi Wewa), and all uninhabited land west of the Namal Oya and the reservoir of that name and/or the road from Iginiyagala to Mullegama.
3. For tourist and visitor development:
a) Have several boats because a trip on the waters of Senanayake Samudraya is an unforgettable experience and the best way to see elephants.
b) Establish one major viewing track and a few jeep tracks. The major track could be from Mullegama via Bubula and Henebedda to Makara where the Gal Oya River enters the lake through a picturesque boulder-strewn gorge.
c) A bungalow and a camping site at Makara.
These suggestions were made nearly 40 years ago and are still valid.
Some time later a foreign company proposed to take over the Gal Oya National Park and develop it as a tourist project. Thilo opposed this project because he feels that in a National Park only full government control, which is subject to public scrutiny, can guarantee the proper maintenance of correct conservation practices. Further, the Fauna and Flora Protection Ordinance does not allow the alienation of land under its purview, or commercial activities such as private tourist camps in National Parks.
This principled stand caused Thilo further worry in his dealings with the WWF, and added to his troubles in the matter of the presidency of the WNPS. The reasons were that a member of the WNPS Committee was the designated Manager of the private Gal Oya project, and the foreign company had close ties to the WWF.
Thilo and the WNPS had upheld the same position in the battle against a chain of hotels along the coast in the Yala National Park, and in the construction of the Society’s own bungalows, which are all outside National Parks.
4) Udawalawe National Park
After years of agitation by the WNPS, the Udawalawe National Park was declared by the Government in June 1972, when Mr S. D. Saparamadu was Director of the Department of Wildlife Conservation. Like Gal Oya it was mainly meant as a protection for the reservoir.
The new ‘Park’ was in desolate condition. It was crisscrossed by tracks for the extraction of timber and large-scale cultivation. Large numbers of people worked in felling camps, and many capitalist landholdings had been cleared. Bananas, chillies, tobacco, tomatoes and other crops were grown, with paid labour living in wadiyas on the land. Much of the forest had been cleared, and wild animals exterminated in these areas. The Park was a hive of illegal human activity.
There were also extensive teak plantations, and the State Timber Corporation was busy removing all the usable timber trees from the area.One month after the declaration Hoffmann visited the new Park, mostly on foot, during several days, and wrote a detailed report, which was later published in Loris, titled ‘The New Uda Walawe National Park’. A copy with a request for action was handed over to Mr Saparamadu as Director of the Wildlife Department. It is the only detailed account and description of the state of all parts of the Park at that time, and contains a number of specific recommendations for improvement.
During that visit the newly appointed Park Warden had stated: “It was a mistake to declare this Park.” He felt that it was beyond redemption, as did his mentor and friend, the earlier Director. Thilo comments:
“Contrary to what S. D. Saparamadu writes in his book Sri Lanka: A Wildlife Interlude (2006), the Wildlife and Nature Protection Society welcomed the establishment of the new Park for which it had lobbied over the years. This is recorded in the WNPS annual reports and Loris as they had foreseen its great potential.
The Society, however, was not happy when after the declaration nothing happened with regard to the desperate situation of the Park, despite the appointment of a few staff without the means to assert the Department’s authority over it. When Director Saparamadu retired a few years later, in early 1975, the Park was in the same desolate state.
Subsequent Directors did what was required, and the Park was properly opened for the public in 1980. It was also somewhat enlarged, and now comprises 30,821 hectares. It has amply fulfilled the high expectations which Thilo and the WNPS had of it. Thilo says:
“Saparamadu’s book contains many more distortions, manipulations of facts and downright untruths. There is hardly a chapter in which he does not disparagingly refer to “the wildlife establishment”, by which he means the WNPS, described as “western educated, English speaking and mostly Christian”. He and – in some ways – his predecessor were the extreme cases of supercilious bureaucrats with minds battened down against anything and anyone outside their own establishment. Arrogant confrontation and denial instead of friendly collaboration was the rule.”
In Thilo’s report to Loris in 1972 – written after his visit – he noted the matters set out below:
1. In the eastern sector, there were at least four timber wadiyas. The area had been systematically logged since the 1950s. As a result there were no large trees to be seen anywhere.
2. Large tracts of abandoned chenas were overgrown with Lantana and eupatorium, the latter recently introduced from abroad: New land was being cleared for cultivation.
3. The Forest Department had established 3,500 acres of teak plantations in the Park. 500 acres were newly earmarked for a three-year chena control system.
4. Inside the eastern sector there are two ancient villages, Sinuggala with four families and Nebodawewa with two families.
5. Few animals were observed. A leopard was seen, a very rare occurrence here. The presence of elephants was noted. It was recorded that there was a potential carrying capacity of about 150 elephants. Though not a single spotted deer was seen, dry deer skins were observed in timber wadiyas.
6. Logs were being loaded into lorries using tame elephants.
7. The situation in the western sector of the Park (west of the Walawe River) was very similar with chenas and settlements. The latter would have to be excised, but the higher lying part, north of Kuda Oya, was ecologically very valuable because of its special character, containing talawa.
The report (in 1972) ended with the following sentence: “The new Uda Walawe National Park has a future and is worth a special effort; no more time must, however, be wasted.”

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.
