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.

‘There are no private universities in Sri Lanka’ – some considerations for higher education reform
Academics involved in education policy like to say that there is no such thing as a private university in Sri Lanka. The only ‘universities’ in the country are state universities; anything else offering degrees is a private higher education institution (HEI). This position is technically accurate. Yet, in the discourse and imagination of the public, private universities are very real – people teach in them, students register in them, families pay fees, and such degree holders enter job markets in Sri Lanka and outside.
For decades, activists concerned for public higher education have ignored or resisted looking at private HEIs, as if such scrutiny would taint them. Others have worked in both types of institutions, carrying practices from each to the other. The apex body governing state universities, the UGC, has, meanwhile, ignored the concept of conflict of interest and appointed individuals in private higher education in committees and leadership positions. It is unsurprising then that some of the ideologies informing private higher education appear in reform agendas in the state sector.
This is a good time then to consider the varying types of private HEIs around us, and to take a look at some of the issues within them in the hope that higher education reform agendas will include private, as well as state higher education.
What is a ‘private university’?
First, some clarifications. In the public imaginary, a ‘private university’ is typically an institution that provides a foreign or local degree for which the student makes a payment. But this broad classification encompasses a host of diverse institutions and types of degrees which I detail below.
The Non-State Higher Education Division (NSHE) of the Ministry of Education has recognised 295 degrees by 32 institutions. Most of these are private companies and include a handful of established, well-known private HEIs that are ‘university like’. The degrees are local degrees conferred by the institutions accredited by the NSHE Division. While private HEIs conferring local degrees must be accredited by the NSHE Division, there appears to be no legal consequence for not doing so. In addition, there are several permutations of the private degree that miss the net of this Division and the Standing Committee on Accreditation and Quality Assurance (SCAQA) that assists this Division.
For one, degrees conferred by foreign universities offered, via these same private HEIs, are not vetted by the NSHE Division. Secondly, there is a growing plethora of private HEIs which have either no physical presence locally or only a dubious presence. The University Grants Commission has notified the public, through their website, that foreign universities listed in the Commonwealth Universities Yearbook and the World Higher Education Database are recognised, but refrained from giving any other details – which degrees? Offered by what modes? These details are not known. Some of the foreign universities in the lists may be legitimate entities in their own land but the degrees conferred locally, in their name, may not adhere to curriculum or teaching specifications of the NSHE Division or the UGC.
Another troubling phenomenon is the ‘top up degree’, which appears to work on the same principle as that of a pre-paid mobile connection: if I have a Diploma or an HND of a sort, I am eligible to complete a course of study which provides me with a degree, usually from a foreign university. The idea that someone who does not initially qualify for a degree programme should be able to work their way towards one is a progressive notion. This is the concept that open and distance learning (ODL) was based on initially, but which is now sadly exploited. ODL models are expected to provide opportunity for learning for those who may be excluded from traditional learning institutions. In Sri Lanka, however, we have seen ODL become a marketplace offering easy to obtain, for-fee qualifications by institutions with little commitment to superior teaching and learning.
Finally, a perusal of the many types of private HEIs and their varied degrees bring to mind another question – how should the private degrees, provided by state institutions (that are not educational institutions), be regulated? Who should do so?
All of these create a host of problems for the public – for hopeful students and parents and trusting employers. For the higher education sector, recruitment of academic staff, too, has become difficult due to this plethora of ambiguous higher education qualifications, as I discussed in a previous Kuppi article (‘Recruiting academics to state universities’).
Some issues in private HEIs – a bellwether for change in state universities
In this second part of this article, I will discuss some aspects of work in private HEIs – albeit the more established institutions – given that such issues may appear in reform agendas in future.
Across state universities, all permanent staff of a specific category are paid according to the same criteria. The picture is not so clear when it comes to private HEIs since they are different entities legally, typically companies. Private HEIs have salary scales and financial incentives that are different to each other. The more established private HEIs reportedly have attractive renumeration packages, possibly a reason for academics of state universities migrating eagerly to such institutions during sabbatical years and on retirement. This may not of course be the case with other less established, or improperly registered HEIs of which we know little. Academic staff of these more accepted private HEIs seem to value the high financial remuneration they receive (in comparison to state universities) as something that makes their work rewarding.
Attractive remuneration is important to sustain the good life and is at times seen as the institution’s way of encouraging good work. Yet, this has implications for the future of the institution: to continue to deliver on promised financial packages, institutions must continue to have large profit margins. One strategy has been to enroll multiple cohorts of students per year, even up to three or four intakes per year. This can result in exploitative work conditions, since staff must cater to all these cohorts in that same year. If there is inadequate staff, employees are further burdened. On the other hand, if there is a sudden drop in enrolments (degrees can go out of fashion) unexpected layoffs occur. Similar to other sectors that employ short-term contract staff – including state universities – in private HEIs, too, individual teachers, who are on short term contracts that need regular renewal, can feel pressured to work under difficult or exploitative conditions.
At the same time, even in the more established private HEIs, work norms differ from those of state universities in that they include promotional work that keeps the institution’s name in the eye of the public. The Marketing (or similarly named) unit comes up in conversations as one of the most important departments. It appears to weigh in on decision-making related to the number of staff, the amount of re-sits per exams, and other pedagogically important matters. This is a worrying example of how financial rationales interfere with pedagogically or academically sound processes, resulting in problematic results in the classroom. On the plus side, junior colleagues, who had experience in both state and private HEIs, also felt that they faced less harassment in private HEIs – primarily due to the private HEIs ability to take swift action in reported cases of harassment. This is a real indictment on state institutions and their reluctance to address chronic issues of harassment in our universities.
Yet, while we hear much about problems in state universities, we hardly hear of problems that staff in private HEIs face. One rationale for a lack of public expressions by staff is that expressions of discontent might lead to trouble given the importance of reputation for private HEIs. The worry about reputational damage is a growing concern in state universities, too, as evidenced by social media policies and internal conversations on reputational damage, consequent to negative publicity. Institutional worries of reputational damage are harmful in the long run since these impact not only freedom of expression by student and staff, but also research that is possible in and about the education sector.
Some thoughts at the end…
A close look at the private higher education sector is important given its strong presence in the country. Impending reform needs to regulate this diverse array of higher education offerings in the private sector, as well as the state institutions that offer privately-funded options of higher education (a topic for a separate Kuppi on its own). It is time we carefully considered how to build a whole system of higher education out of this broken mess.
