Clean energy without foreign exchange
[This article is dedicated to the late Dr. Janaka Ratnasiri who tirelessly worked hard to make the country move away from fossil fuels.]
According to a news report published in The Island (17 July 2021), the CEB Engineers Union had stated that the government’s target for increasing to 70% the electricity from renewable energy to the national grid is not practical. Apparently, even if it were practical, the CEB does not have computerised infrastructure for managing the variable switching-in and switching-out, needed for integrating “non-firm” energy sources like wind and solar into the grid.
The CEB can say, if we only had that “excess capacity” then blackouts wouldn’t happen! But this is irrelevant, given Dr. Siyambalapitiya’s admission (The Island 19-08-20) that “the system” cannot even handle a 0.5% power fluctuation from “unmonitored” sources like “solar and wind”.
Engineer S. Kumarawadu, the President of the CEB Engineers Union, claims that transmission lines have to be upgraded to meet targets. That should have been a part of the long-term plan anyway. One hopes that the CEB union is more reliable than the GMOA, where Dr. Padeniya has been making statements from cloud cuckooland itself (see https://www.youtube.com/watch?v=rGe6ld2q1vs).
The views of the CEB Engineers Union are very relevant to the country’s energy planning. However, it also has gross vested interests. What the power sector in Sri Lanka does NOT have, is an independent Research and Development (R&D) arm, similar to the Tea Research Institute, Coconut Research Institute, etc., available for agriculture. It is the vital research done by the rice research institutes in developing high-yielding seeds that kept up with the population explosion and fed the country. They faced political bulls running amok in the agricultural china shop, advocating a return to traditional seeds, traditional manure, and the use of occult practices like “kem”, while advocating getting rid of “all chemicals”.
As they are not guided by an R&D arm, the engineer managers choose conventional turn-key solutions that they know of. The CEB is an “unthinking beast” that does not run research projects or pilot plants and patent new ideas. Its “Long Term Generation Planning” (LTGP) Branch makes a no-brainer expansion plan every year.
The CEB’s LTGP 2015-2034 is still excessively tied to fossil fuels. This is not surprising, as it does not have the capacity to integrate new technologies, or even run a proper simulation of its own system, its power failures and blackouts. It has gone to Canadian, European or Japanese organisations to do simulations that should have been “in house” jobs. Its “research” is at best a tender board tango done with wheeler-dealing politicians. The CEB ends up blaming politicians who canceled “well-laid” LTG plans, while the politicians blame an uncooperative “CEB mafia”!
Consider the claim (see The Island, 17th July) that supplying 70% of the needed power using renewable sources is not practical. This is contradicted by other information sourced to the CEB itself. A news report (23-12-2019, The Island) claimed that when there were heavy rains, 70% of the power needed came from hydroelectricity. Similarly, on 10th August 2020 the CEB reported that over 50% of the power came from hydro as there had been adequate rains.
Some 40 GWh is needed at present. Hydroelectricity provides about 20 GWh of this, while coal provides some 18 GWh. As mentioned above when there is sufficient rain, 70% of the needed electricity comes from hydro! That is, some 28 GWh can be harvested if the water levels are preserved over the two monsoons. So, this increased the the hydro-electric output by some 40%. This figure is consistent with high hydro-electric outputs in the rainy seasons.
When the reservoirs are full, the evaporation is also extreme. King Parakramabahu wanted to use every drop of water reaching the ocean but did not consider evaporation. In my writings during the past two decades, I have pointed out the need to stop the over 30-40% evaporation losses happening day and night, due to the wind and the prevailing heat. These worsen with global warming. During heavy rains the water spills over and gets wasted. Additional storage to save spill water by restructuring reservoir dams, and using locally made floats to cover parts of the surface to cut evaporation can boost the hydro-electricity output over 30-40%.
So far, just by protecting the water from evaporation and spillage, we gain perhaps a 30% boost in hydro-power without using any solar panels. Floats can be added WITHOUT foreign exchange. If solar panels and wind turbines are added around these reservoirs, even more energy is harvested. Do your own calculations to see what you get! For answers, see my earlier articles, e.g., The Island of 15.07.2020, or 31-08-20: https://island.lk/sri-lankas-power-supply-blackouts-and-how-to-prevent-them/). Hence you don’t need any fossil fuel in the end.
Evaporation control will become extremely acute with increased global warming. Otherwise, even the 20GWh currently supplied by Hydro will dwindle down due to extended droughts. However, once the systems are set up to prevent evaporation, the gained 30-40% increase in hydroelectricity is produced by a gain in head water in the reservoir. NO STORAGE BATTERIES ARE NEEDED. This is “firm energy” and remains compatible with the utterly outdated grid stabilization schemes still used by the CEB.
So, preventing evaporation will rapidly increase the island’s power capacity by, say, 30% . Given some 22 major hydroelectric reservoirs with a surface area of about 1000 ha each, if 50% of the surface be covered using floats, 11,000 ha (110 sq km) are protected. It can be shown that the environmental impact is positive. The water quality is improved due to reduced algae growth. The annual hydro-power of about 6000 GWh will rise to 8000 GWh when evaporation is cut. This is the cheapest and cleanest possible electricity!
Typically, sunlight can annually produce about 100-200 GWh per sq. km (100 ha) under Sri Lanka’s conditions. If solar panels are also placed on the floaters deployed to cut evaporation, then 1000-2000 GWh per annum of solar energy can be harvested, with no hassle or delays in acquiring land rights. Any excess daytime energy can be saved by retaining the corresponding amount of hydro-head in the reservoirs, without sending the reservoir water down into the turbines. That is, solar electricity has been stored without batteries and converted to firm power!
Furthermore, evaporation shields, equipped with solar panels are a one-time capital investment, and there is no need for continued importation of LNG, coal or oil as envisaged in the conventional expansion plan of the CEB that takes no account of global warming. The type of costly infrastructure development needed for LNG is not needed for the simple approach of cutting down evaporation, as the first conservation step that will boost Sri Lanka’s clean power capacity. And yet, in the LTGP 2020-2039, the CEB has only paid lip service to government policy on fuel diversification by adding LNG-based generating capacity, whereas LNG is an expensive fossil fuel that should have been avoided! Why is LNG energy being falsely referred to as “clean energy” in CEB documents?
However, unconventional solutions should NOT be implemented without running pilot projects. Such projects must be run by a yet to be established Power Research Institute, which should have been established at least in the days of the accelerated Mahaweli project. A first floating solar project has been proposed near the Parliament, on the Diyawanna Lake. But this is largely a no-brainer as the Diyawanna lake is not connected to a turbine, and no gain in evaporation is achieved. No natural mechanism of energy storage, as saved water is available and one has to resort to batteries.
Some unconventional solutions that have been proposed (without any trials or pilot projects) include the use of urban garbage as an energy source, while ignoring the now well established biomass approaches that use fast-growing Giricidia or Castor to produce dendro energy. Several 10MW dendro plants already exist, and establishing 20 more within the next 2-3 years, to add 200MWs of capacity is straightforward.
Attempts to use urban garbage in settings similar to Sri Lanka, e.g., India, has led to failure in actual operations. Only a total of 138 MW has been installed in India by 2019 although its garbage output is massive. The extreme wetness of the garbage, inadequate separation of wet garbage from dry garbage, and the difficulties of plant operation for methane production, incineration and pyrolysis, and disposal of toxic ash have become serious problems. This is, in my view, an unsuitable approach for Sri Lanka, although suitable for a research and development (R&D) pilot project, since Colombo alone produces 2-5 thousand tons of urban garbage per day. Sri Lanka should develop dendro power while leaving “garbage to energy” conversion as an R&D project.

A tariff deal with the US? Make haste slowly
by Gomi Senadhira
Sri Lanka’s former ambassador to the United States Mahinda Samarasinghe is back in Sri Lanka lobbying for speedier finalisation of a new tariff deal with the United States. According to news reports, delivering the keynote address at the Sri Lanka Institute of Directors’ Annual Meeting last week, he stated, “I have recommended very strongly to the government that we need to conclude the agreement so that we can lock in the very favourable tariff rate that Sri Lanka has got up to now“.
I do not understand why the former ambassador is urging the government to expedite the finalisation of a new tariff deal or what is “the very favourable tariff rate” he refers to in his speech. However, given the ongoing terrible tariff turbulence in the United States and the fragile economic situation in Sri Lanka, I believe, this is not the right time to rush into finalising any trade agreement with the United States. I am also of the opinion that at this juncture Sri Lanka should maintain strategic patience and explore all available options.
Lessons from the countries that rushed for trade deals
To better comprehend this, let’s look at experiences of the countries that rushed to conclude tariff deals with the United States after President Donald Trump declared his “reciprocal tariffs” under the International Emergency Economic Powers Act (IEEPA) in April 2025. As Samarasinghe stated in his keynote, “The bottom line on all these negotiations was that every country that finally agreed to sign the agreement had to give either complete duty-free access for American exports into those markets, or near complete duty-free access.” In exchange for these tariff concessions and other market access commitments these countries managed to get the newly introduced country specific “reciprocal tariffs” reduced.
However, in February 2026, the Supreme Court of the United States (SCOTUS) struck down these “reciprocal tariffs” under the IEEPA. With that, the market access gains these countries received in exchange for complete duty-free access for American exports into their markets evaporated under U.S. domestic law. By moving too fast to conclude bilateral tariff agreements with the United States these countries are now bound to strict obligations whereas the benefits they bargained from the U.S. administration are not worth the paper those were written on.
Sri Lanka’s experience
In April 2025, President Trump declared his “reciprocal tariffs” and labelled Sri Lanka as the worst offender, imposing one of the highest additional duties at 44%. Since then, Ambassador Samarasinghe and other negotiators have managed to negotiate this down to 20%. I do not know what the deal was through which Sri Lanka managed to reduce the 44% tariff to 20% or what we gave in return for this “concession.” However, what we received in return has absolutely no value after the decision by the SCOTUS.
Current state of US tariffs
After the decision by SCOTUS, the U.S. administration introduced a temporary 10% additional tariff on all countries for 150 days. At the end of that period, this 10% tariff was replaced by a new “forced labor tariff ” of 10% to 12.5% on all trading partners under Section 301 of U.S. trade law. Twenty-five U.S. states and several small businesses have already filed lawsuits against these tariffs in U.S. courts. This new “forced labour tariff ” on Sri Lanka was first fixed at 12.5%. Later, after President Anura Kumara Dissanayake issued a gazette notice prohibiting the importation of goods produced using forced labour, it was reduced to 10%. That means Sri Lanka has already made a substantial commitment to receive this “tariff concession,” and I presume our negotiators understand the implications of this commitment.
Make haste slowly
After President Trump imposed 44% “reciprocal tariffs” on Sri Lanka, through an article published in The Island on 25th April 2026 (), I urged the government to engage immediately with the US administration on these tariffs. However, I also emphasised that the best way to move forward was to make haste slowly.
Two millennia ago, Augustus Caesar, the first emperor of Rome, frequently used the phrase, “make haste slowly”, because he detested rashness and haste in his military commanders. It was the recurring guiding maxim that he emphasised throughout his 40-year imperial rule. After 2000 years, this classical oxymoron remains a definitive golden rule for professional trade negotiators. More importantly it is the exact blueprint required when navigating turbulence in trade negotiations with the Trump administration.
The endgame – The most dangerous moment in trade negotiation
Samarasinghe has also stated the agreement is 90% complete. Any experienced trade negotiator should know that the final 10% contains high-stakes provisions and is the most dangerous moment in a trade negotiation. A single misplaced comma or ambiguous product description in a tariff schedule can cost millions through unintended loopholes. Rushing this last stretch to secure a deal can permanently expose Sri Lanka to sudden shifts in American trade policy, heavy compliance costs, or strict enforcement under Section 301 regarding supply-chain labour standards. Hence, this is the time for strategic patience.

Buddhist law and constitutional amendments
Upon reading the article titled “Prof. Pieris says Buddha Dhamma recognized as source of law under Constitution” (Island, September 12, 2026), the classical Sinhala idiom “Yanne Koheda? Malle Pol” immediately comes to mind. The expression, translating literally to answering “I have coconuts in my bag” when asked “Where are you going?”, underscores a complete disconnect in logic. Because it is uncertain whether the article accurately represents the professor’s precise words, the following critique addresses the contents of the report rather than the speaker himself.
The central premise of the report concerns a statement delivered by the Chief Justice regarding a petition filed against the 22nd Amendment to the Constitution. According to the report, the Chief Justice’s observation that the determination would be made strictly on the basis of established law rather than Buddhist teachings was characterised as a “cavalier dismissal” of the Buddha Dhamma. This assertion carries a host of unexamined assumptions. Had the writer specified precisely which tenets of the Buddha Dhamma were violated, a direct legal or philosophical evaluation could take place. However, no specific Buddhist tenet or law was identified as having been transgressed, and for good reason: no such statutory legal framework exists within the Buddha’s teachings.
To understand the flaw in this argument, one must examine the constitutional context alongside the canonical meaning of the terms involved. Article 9 of the 1978 Constitution of Sri Lanka mandates that the Republic shall give Buddhism the foremost place and that it shall be the duty of the State to protect and foster the Buddha Sasana, while guaranteeing the fundamental rights of all religions under Articles 10 and 14(1)(e).
While “Buddhism” and “Buddha Dhamma” are frequently used as interchangeable terms in casual dialogue, they represent distinct concepts. “Buddhism” is an umbrella term coined by 19th-century Western scholars to classify the global institutionalised religion, incorporating its diverse sects, cultural traditions, rituals, and socio-political histories. Conversely, Sasana is the ancient term designating the structural framework established by the Buddha to preserve and transmit his teachings, comprising the monastic order (Sangha) and its supporting institutions.
In classical Theravada commentarial literature, the Sasana operates as a functional three-tiered structure. It encompasses Pariyatti Sasana, the preservation and study of sacred texts; Paṭipatti Sasana, the practical execution of the doctrine through ethical conduct and meditation; and Paṭivedha Sasana, the direct experiential realization of ultimate truth, or enlightenment. This structural breakdown raises fundamental questions about state capacity. While a state can readily support Pariyatti Sasana through academic institutions, textual preservation, and educational funding, it cannot legislate or enforce Paṭipatti or Paṭivedha. Practical engagement and spiritual realisation are inherently internal, first-person experiences. Expecting the state to codify or guarantee enlightenment is a conceptual impossibility.
Furthermore, the Buddha Dhamma refers specifically to the unconditioned truths of existence and the teachings imparted to realize them, including the Four Noble Truths, the Eightfold Path, and Dependent Origination. As the late Venerable Professor Kotagama Wachissara Thera observed, there is no rigid ideologue or “ism” in the core Dhamma. The teachings do not constitute a system of divine commandments or a legal statute enforced through reward and punishment. Rather, Buddhist ethics function as self-directed guidelines for psychological clarity and moral inquiry. Even the Vinaya Pitaka, which contains explicit rules of conduct, functions as an internal monastic code rather than a civil or criminal law intended for the laity.
Throughout the Pali Canon, guidance regarding governance focuses on the moral character of leadership and the social duties of statecraft rather than rigid legal codification. In discourses such as the Cakkavatti Sihanada Sutta (DN 26), the Buddha observes that social instability and crime cannot be eliminated solely through punitive measures, emphasising instead that states must provide economic opportunities, fair wages, and resource distribution to maintain societal balance. Crucially, in the Maha Parinibbana Sutta (DN 16), the Buddha explicitly highlights the importance of respecting established laws and traditions rather than enacting arbitrary regulations.
The natural laws articulated in the Dhamma, such as the law of cause and effect or the three characteristics of existence, govern all phenomena universally, regardless of legal statutes or personal belief. They are not human laws to be applied or suspended by a court of law. Therefore, characterizing the Chief Justice’s adherence to constitutional jurisprudence over religious doctrine as a “cavalier dismissal” lacks logical and textual foundation. Framing the judiciary’s adherence to legal precedent as an attack on the Dhamma distracts from fundamental constitutional principles and risks misguiding the public for political ends.

Elementary, Dr. Watson!
by Usvatte
My friend, Sena Thoradeniya, has summoned up energy to raise two questions about my observations in your newspaper on 14 September, 2026. They both referred to comments I made about President Dissanayake and Prime Minister Amarasuriya.
I observed that President Dissanayake, having graduated in physics at Kelaniya, would be familiar with elementary calculus: differentiation and integration. It is a misapprehension to believe that one needs any knowledge of theoretical physics to be familiar with elementary calculus. Nor is it necessary that one needs to have published research for the same purpose. Those were the first lessons in calculus that our Mathematics Master and Principal, Mr. D. A. Devendra taught five of us in the first term 1952 at Hikkaduva Central School. Of the five, two still live and recall those lessons vividly. Dissanayake would surely have learnt them at his school in Anuradhapura. At Kelaniya his teachers probably included Dr. H. Somadasa, two years my junior at Hikkaduva, with a Ph.D. in number theory at Aberytswyth, Wales and Professor (physics) Charles Dahanayke, a renowned teacher of physics and my neighbour in Colombo. Dissanayake is unlikely to have been admitted to Physics at Kelaniya unless he had scored well in mathematics and physics with other subjects. Those elements of calculus have been learnt by millions of young men (and later women) since Isaac Newton and Gottfried Leibnitz. That Dissanayake from a school in Anuradhapura scored high enough to gain admission to Kelaniya to study physics is commendation enough for his intellectual capacity.
All of us know, some personally, the barriers to learning in places like Anuradhapura and Kuliyapitiya, compared to the facilities in Colombo, Galle. Jaffna and Kandy. I used that information to press the point that he was, in learning, entirely different from his predecessors and present competitors. One does not need to research in theoretical physics to know something as simple as the first lesson in calculus. Dirac made his momentous discovery sometime in the 1930s and by 1950 it must have been solidly in the teaching material in schools and universities. Dissanayake graduated in 1995 and, at least, must have heard of Dirac and the ‘God Particle’.
Paul Dirac was a legendary figure among graduate students when I was at Cambridge. He had written the shortest Fellowship and Ph.D. theses. He had had an interesting relationship with his father who was a French speaking Swiss and had insisted that he speaks French at table. Amrtya Sen, who was in 1965 a young Fellow of Trinity College and a teacher in the Economics and Politics Faculty at that time, had also written very short theses and not several volumes as many do.
I read about Higgs Boson in a wonderful book Inward Bound written by physicist Abraham Pais and, in The Science Times (Tuesdays) edited by Gina Kolata of the New York Times, and occasionally in Nature and other popular writings.
I was on the editorial board of Samskrti for some time. Amaradasa Virasinghe and Gananath Obeysekera had started that literary review in 1953 when I was in school and many of us read it avidly. Together with Susil Sirivardana, we decided to expand the scope of the journal to include social studies and science, which effort Sena knew well. The probable readership had increased manifold. In order to help prospective writers to pick up themes to write on, we held a popular lecture, one Saturday a month. I invited Dr. Harini Amarasuriya, then teaching at the Open University, Nawala, to speak to us on the scope and nature of sociology. She made a short fine introduction. That is where I learnt of August Compte. She was invited to a Seminar in Britain on the sociology of education, where I had strayed into from 1971. I did not read her paper, although she had promised to let me have it. I had good reason to respect her scholarship. It would be shocking had she not read Le`vy-Strauss. Many besides anthropologists read Le`vy-Strauss.
Sena stressed the obvious when he said that in public speeches made by these two politicians, there was no evidence of their expertise in physics and sociology. It would have been completely out of place to speak about elementary particles to a crowd in Beruvala or Anuradhapura. But one’s education, in subtle ways, informs the material and the ways that the material is presented in public speeches. Simply listen to Members of Parliament speak and you can guess roughly the level of education each had achieved: grade 2 in primary school or Quondam Professor of Law at Oxford.
I am sorry that Sena identified ‘an exaggerated parade of claims and sheer implausible boasts’ in what I wrote. It is entirely plausible, indeed certain, that an undergraduate in the Department of Physics in any university would be familiar with differentiation and integration.
An unprejudiced reading of my text will demonstrate that it contained no such claims and boasts. Mine was a pretty simple statement of the nature of differences between the present lot in government and the lots that were in power earlier. I related those differences to help understand the line up for and against the 22nd Amendment to the Constitution. and not to build false images of any politician, man or woman. I am too old to set out, even in the formidable company of Sena, on the ‘long march’ to Mao.
