Clean energy without foreign exchange

Published

on

[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.

Why so unbuddhist?

Published

on

Hardly a week goes by, when someone in this country does not preach to us about the great, long lasting and noble nature of the culture of the Sinhala Buddhist people. Some Sundays, it is a Catholic priest that sings the virtues of Buddhist culture. Some eminent university professor, not necessarily Buddhist, almost weekly in this newspaper, extols the superiority of Buddhist values in our society. Some 70 percent of the population in this society, at Census, claim that they are Buddhist in religion. They are all capped by that loud statement in dhammacakka pavattana sutta, commonly believed to have been spoken by the Buddha to his five colleagues, when all of them were seeking release from unsatisfactory state of being:

‘….jati pi dukkha jara pi dukkha maranam pi dukkham yam pi…. sankittena…. ‘

If birth (‘jati’) is a matter of sorrow, why celebrate birth? Not just about 2,600 years ago but today, in distant port city Colombo? Why gaba perahara to celebrate conception? Why do bhikkhu, most prominent in this community, celebrate their 75th birthday on a grand scale? A commentator reported that the Buddha said (…ayam antima jati natthi idani punabbhavo – this is my last birth and there shall be no rebirth). They should rather contemplate on jati pi dukkha and anicca (subject to change) and seek nibbana, as they invariably admonish their listeners (savaka) to do several times a week. (Incidentally, Buddhists acquire knowledge by listening to bhanaka. Hence savaka and bhanaka.) The incongruity of bhikkhu who preach jati pi duklkha and then go to celebrate their 65th birthday is thunderous.

For all this, we are one of the most violent societies in the world: during the first 15 days of this year (2026), there has been more one murder a day, and just yesterday (13 February) a youngish lawyer and his wife were gunned down as they shopped in the neighbourhood of the Headquarters of the army. In 2022, the government of this country declared to the rest of the world that it could not pay back debt it owed to the rest of the world, mostly because those that governed us plundered the wealth of the governed. For more than two decades now, it has been a public secret that politicians, bureaucrats, policemen and school teachers, in varying degrees of culpability, plunder the wealth of people in this country. We have that information on the authority of a former President of the Republic. Politicians who held the highest level of responsibility in government, all Buddhist, not only plundered the wealth of its citizens but also transferred that wealth overseas for exclusive use by themselves and their progeny and the temporary use of the host nation. So much for the admonition, ‘raja bhavatu dhammiko’ (may the king-rulers- be righteous). It is not uncommon for politicians anywhere to lie occasionally but ours speak the truth only more parsimoniously than they spend the wealth they plundered from the public. The language spoken in parliament is so foul (parusa vaca) that galleries are closed to the public lest school children adopt that ‘unparliamentary’ language, ironically spoken in parliament. If someone parses the spoken and written word in our society, there is every likelihood that he would find that rumour (pisuna vaca) is the currency of the realm. Radio, television and electronic media have only created massive markets for lies (musa vada), rumour (pisuna vaca), foul language (parusa vaca) and idle chatter (samppampalapa). To assure yourself that this is true, listen, if you can bear with it, newscasts on television, sit in the gallery of Parliament or even read some latterday novels. There generally was much beauty in what Wickremasinghe, Munidasa, Tennakone, G. B. Senanayake, Sarachchandra and Amarasekara wrote. All that beauty has been buried with them. A vile pidgin thrives.

Although the fatuous chatter of politicians about financial and educational hubs in this country have wafted away leaving a foul smell, it has not taken long for this society to graduate into a narcotics hub. In 1975, there was the occasional ganja user and he was a marginal figure who in the evenings, faded into the dusk. Fifty years later, narcotics users are kingpins of crime, financiers and close friends of leading politicians and otherwise shakers and movers. Distilleries are among the most profitable enterprises and leading tax payers and defaulters in the country (Tax default 8 billion rupees as of 2026). There was at least one distillery owner who was a leading politician and a powerful minister in a long ruling government. Politicians in public office recruited and maintained the loyalty to the party by issuing recruits lucrative bar licences. Alcoholic drinks (sura pana) are a libation offered freely to gods that hold sway over voters. There are innuendos that strong men, not wholly lay, are not immune from seeking pleasures in alcohol. It is well known that many celibate religious leaders wallow in comfort on intricately carved ebony or satin wood furniture, on uccasayana, mahasayana, wearing robes made of comforting silk. They do not quite observe the precept to avoid seeking excessive pleasures (kamasukhallikanuyogo). These simple rules of ethical behaviour laid down in panca sila are so commonly denied in the everyday life of Buddhists in this country, that one wonders what guides them in that arduous journey, in samsara. I heard on TV a senior bhikkhu say that bhikkhu sangha strives to raise persons disciplined by panca sila. Evidently, they have failed.

So, it transpires that there is one Buddhism in the books and another in practice. Inquiries into the Buddhist writings are mainly the work of historians and into religion in practice, the work of sociologists and anthropologists. Many books have been written and many, many more speeches (bana) delivered on the religion in the books. However, very, very little is known about the religion daily practised. Yes, there are a few books and papers written in English by cultural anthropologists. Perhaps we know more about yakku natanava, yakun natanava than we know about Buddhism is practised in this country. There was an event in Colombo where some archaeological findings, identified as dhatu (relics), were exhibited. Festivals of that nature and on a grander scale are a monthly regular feature of popular Buddhism. How do they fit in with the religion in the books? Or does that not matter? Never the twain shall meet.

Hippocratic oath and GMOA

Published

on

Almost all government members of the GMOA (the Government Medical Officers’ Association). Before joining the GMOA Doctors must obtain registration with Sri Lanka Medical Council (SLMC) to practice medicine. This registration is obtained after completing the medical studies in Sri Lanka and completing internship.

The SLMC conducts an Examination for Registration to Practise Medicine in Sri Lanka (ERPM) – (Formerly Act 16 in conjunction with the University Grants Commission (UGC), which the foreign graduates must pass. Then only they can obtain registration with SLMC.

When obtaining registration there are a few steps to follow on the as stated in the “

GUIDELINES ON ETHICAL CONDUCT FOR MEDICAL & DENTAL PRACTITIONERS REGISTERED WITH THE SRI LANKA MEDICAL COUNCIL” This was approved in July 2009, and I believe is current at the time of writing this note. To practice medicine, one must obtain registration with the SLMC and complete the oath formality. For those interested in reading it on the web, the reference is as follows.

 https://slmc.gov.lk/images/PDF_Main_Site/EthicalConduct2021-12.pdf

I checked this document to find the Hippocratic Oath details. They are noted on page 5. The pages 6 & 7 provide the draft oath form that every Doctor must complete with his/her details. Oath must be administered by

the Registrar/Asst. Registrar/President/ Vice President or Designated Member of the Sri Lanka Medical Council and signed by the Doctor.

Now I wish to quote the details of the oath.

I solemnly pledge myself to dedicate my life to the service of humanity;

The health of my patient will be my primary consideration and I will not use my profession for exploitation and abuse of my patient;

I will practice my profession with conscience, dignity, integrity and honesty;

I will respect the secrets which are confided in me, even after the patient has died;

I will give to my teachers the respect and gratitude, which is their due;

I will maintain by all the means in my power, the honour and noble traditions of the medical profession;

I will not permit considerations of religion, nationality, race, party politics, caste or social standing to intervene between my duty and my patient;

I wish to ask the GMOA officials, when they engage in strike action, whether they still comply with the oath or violate any part of the oath that even they themselves have taken when they obtained registration from the SLMC to practise medicine.

Where nature dared judges hid

Published

on

Dr. Lesego the Surgical Registrar from Lesotho who did the on-call shift with me that night in the sleepy London hospital said a lot more than what I wrote last time. I did not want to weaken the thrust of the last narrative which was a bellyful for the legal fraternity of south east Asia and Africa.

Lesego begins, voice steady and reflective, “You know… he said, in my father’s case, the land next to Maseru mayor’s sunflower oil mill was prime land. The mayor wanted it. My father refused to sell. That refusal set the stage for everything that followed.

Two families lived there under my dad’s kindness. First was a middle-aged man, whose descendants still remain. The other was an old destitute woman. My father gave her timber, wattle, cement, Cadjan, everything free, to build her hut. She lived peacefully for two years. Then having reconciled with her once estranged daughter wanted to leave.

She came to my father asking for money for the house. He said: ‘I gave you everything free. You lived there for two years completely free and benefitting from the produce too. And now you ask for money? Not a cent.’ In hindsight, that refusal was harsh. It opened the door for plunderers. The old lady ‘sold’ the hut to Pule, the mayor’s decoy. Soon, Pule and his fellow compatriots, were to chase my father away while he was supervising the harvesting of sunflowers.

My father went to court in September 1962, naming Thasoema, the mayor, his Chief clerk, and the trespassers as respondents. The injunction faltered for want of an affidavit, and under a degree of compulsion by the judge and the attending lawyers, my father agreed to an interim settlement of giving away the aggressors total possession with the proviso that they would pay the damages once the court culminates the case in his favour. This was the only practical alternative to sharing the possession with the adversaries.

From the very beginning, the dismissals and flimsy rulings bore the fingerprints of extra‑judicial mayoral influence. Judges leaned on technicalities, not justice. They hid behind minutiae.

Then nature intervened. Thasoema, the mayor, hale and hearty, died suddenly of what looked like choking on coconut sap which later turned out to be a heart attack. His son Teboho inherited the case. Months later, the Chief clerk also died of a massive heart attack, and his son took his place. Even Teboho, the mayor’s young son of 30 years died, during a routine appendectomy, when the breathing tube was wrongly placed in his gullet.

About fifteen years into the case, another blow fell. A 45‑year‑old judge, who had ruled that ‘prescription was obvious at a glance, while adverse possession was being contested in court all the time, died within weeks of his judgment, struck down by a massive heart attack.

After that, the case dragged on for decades, yo‑yoing between district and appeal courts. Judges no longer died untimely deaths, but the rulings continued to twist and delay. My father’s deeds were clear: the land bought by his brother in 1933, sold to him in 1936, uninterrupted possession for 26 years. Yet the courts delayed, twisted, and denied.

Finally, in 2006, the District Court ruled in his favour embodying every detail why it was delivering such a judgement. It was a comprehensive judgement which covered all areas in question. In 2015, the Appeal Court confirmed it, his job being easy because of the depth the DC judge had gone in to. But in October 2024, the Supreme Court gave an outrageously insane judgment against him. How? I do not know. I hope the judge is in good health, my friend said sarcastically.

Lesego paused, his voice heavy with irony “Where nature dared, judges hid. And that is the truth of my father’s case.”
