Electricity Consumption: Our responsibility
The November flooding in Thailand with a death toll of more than 500 has been described as one of the most damaging natural disasters in Thai history. Although climate change scientists are still unsure of whether there is a direct link between these floods and climate change, there is a general consensus that recent climate changes are likely to be a result of global warming, i.e., greenhouse gas emission.

According to the International Energy Agency, the biggest contributor to high levels of CO2 emissions is the energy industry, which accounts for 41 percent of emissions, followed by the transport industry (23 percent) and the manufacturing industry (20 percent) in 2009. In Malaysia, a UTM study in 2010 projected CO2 emissions in the country would reach 285.73 million tonnes (from 187 million tonnes in 2006) with 43.4 percent coming from the power industry. Although Malaysia does experience some occasional flooding on a small scale, there is no evidence to suggest that the volume of CO2 emissions in the country is the main cause.

Nevertheless, in light of the global emission of CO2, Malaysia made a commitment at the climate summit in Copenhagen in 2009 to reduce its CO2 emissions by 40 percent of its 2005 levels by 2020, subject to assistance from developed countries. It may seem impossible to reconcile such an ambitious reduction target whilst entertaining aspirations of becoming a developed nation within the same period, but it really should not be. What this goal does require is a clear understanding that the responsibility to achieve this balance between development and being environmentally friendly rests on both the industries and the consumer. The energy industry has to secure a viable, sustainable and affordable power supply without sacrificing the Earth's resources. And to achieve this, it could use incentives from the government and technical and financial assistance from developed countries to maximise its increased use of renewable energy sources as well as clean technology. Consumers on the other hand, have to play a role in moderating their demand for electricity through managing how they use this precious commodity.

According to the Ministry of Energy, Green Technology and Water (KETTHA), peak demand for electricity in Peninsular Malaysia reached 15,476 Megawatts in May 2011, a 2.7 percent increase from the previous year. Based on the current projection, the peak demand is expected to reach 21 Gigawatts (GW) in 2020 and 25 GW by 2030.

The energy industry currently relies on finite resources such as fossil fuels to generate power for electricity. Although the impact of CO2 emissions on the environment is undeniable, Malaysia still has more than 60 percent of its land covered with rainforest, whereas most developed countries have less than 30 percent. The issue of CO2 should not be overly emphasised because the country's rainforest could probably absorb more CO2 than is currently produced.

In the long run, the energy industry needs to find alternatives to depleting fossil fuels.

In Malaysia, the government has initiated a holistic review of the energy industry with a view of making it sustainable, reliable and efficient.

One of the areas that has always been considered is now part of the effort towards enhancing the use of renewable energy. Wind, solar, and hydro power stations all operate with close to zero CO2 emissions and will not only assist with alleviating the fuel supply problem but will also reduce climate change problems. However, these alternatives are not so quite dependable or feasible since the cost of producing electricity in this manner is significantly higher than using fossil fuels.

The recent introduction of feed-in tariff (FIT) system, which imposes a 1 percent tariff on those who consumes above 300 kilowatt hours (kwh), to fund the development of renewable energy managed by the Sustainable Energy Development (SEDA) under KeTTHA is a resounding success, especially for solar photovoltaic technology. However it needs a subsidy of a 1 percent levy or more.   

Among the sources of renewable energy currently available in Malaysia are hydropower, solar, biomass from rice husks, palm oil waste (bio fuel) and municipal waste. These are alternative energy sources we can consider for the future. However, all of them are not viable on their own and need subsidies to ensure financial feasibility.

Thus we are left with the cheaper energy source: fossil fuel. However , we can save the Earth by reducing the consumption of electricity and by realising cheap electricity should be cherished. Curbing CO2 emissions is not the responsibility of solely the government or the energy industry because it is not the generation of electricity that contributes to greenhouse gas emissions. Rather, the people who consume electricity are also contributing to emissions.

All consumers - industrial, commercial and residential - need to embrace this green challenge.

The argument that "it won't affect me" is not valid. We live in an age of globalisation where everything is interconnected. So when the price of chillies from Thailand increases, consumers in Malaysia feel the heat. When your factory cannot operate because of the lack of availability of parts due to flooding in the country making those parts, you feel the impact. The selfish suggestion to leave it to others to save the environment is an unrealistic proposition.

Moving towards renewable energy should not be seen as an all encompassing solution to energy problems. It is merely a substitute for fossil fuels that contribute towards CO2 reduction. The bigger culprit is still electricity consumption. It defeats the purpose of the mission if electricity created with clean technology continues to be consumed imprudently.

The Water and Energy Consumer Association of Malaysia believes that consumers can develop responsible energy consumption habits and stop wasting electricity simply because it is cheap or affordable. Using the remote control to flick through channels is fine, but most people tend to switch television and stereo sets off with remote control, leaving them on standby overnight. Even appliances left on standby consume some energy, and this can be saved right away. Lights should not be left on when nobody is in the room. Business should encourage employees to save electricity by switching the lights off when a room is empty and by switching of individual computer consoles when they finish work.

Energy efficient appliances use less energy and save money, which is why the government has developed programmes like the Sustainability Achieved via Energy Efficiency or Save through which rebate vouchers are provided for the purchase of energy efficient refrigerators and air conditioners. Energy-saving bulbs not only save energy but also last longer than regular light bulbs. Next to refrigerators, tumble dryers consume the most amount of electricity. Using tumble dryers in a country with six hours of sunlight a day is ludicrous when in the west, as soon as a glimmer of sunshine is seen, people cannot wait to hang their clothes outside to dry in the sun.

Leading the change for businesses and individuals to follow suit, all government offices have been instructed to set their air conditioning thermostats at 24 degree Celsius because this is considered an appropriate temperature for the local climate. With this in mind, people in offices and homes should take the hint and stop functioning in freezing temperatures. If you need to sleep under a duvet in tropical Malaysia, then your air-conditioner is set too low. Wouldn't it be cheaper to switch on the air-conditioner for a short time to cool down the room and then use the ceiling fan to maintain the temperature?

Our electricity tariffs have been kept too artificially low for too long through heavy subsidies. Even with the recent tariff increase, Malaysia's tariffs are lower than most Asean countries except Indonesia. The time has come for consumers to take some responsibility in saving the Earth. Wasting electricity is a habit we need to remove from the Malaysian mindset. Children need to be made aware of the importance of saving electricity through early education in school. Until each of us adopts measures to reduce our demand for electricity, we can consider ourselves partly responsible for the next climate-related  disaster that occurs.

If you reduce your consumption by one megawatt hour, you can save 0.7 tonnes of CO2, so why not start today and develop the habit of saving electricity?

Cool Roof Reflections
Buildings Can Gain Many Benefits from Cool Metal Roofing

Whether for new construction or existing applications, cool roofs are one of the most adaptive energy-efficiency strategies you can incorporate into buildings. They are beneficial in a variety of climates and building types, can be combined with other environmental measures, and are available in virtually all product types, allowing for innovation and design creativity.

With thousands of color, texture, and profile options available, cool roofing is a particularly viable option for metal roofing. While cool roofs have been used as a passive cooling strategy around the world for thousands of years, new technologies constantly are being researched and developed.

Cool roofs have the potential to save 10 to 30 percent of a building’s cooling energy and may provide additional environmental and health benefits. However, these can only be achieved if the roof is properly selected and installed. We will help decode the science and terminology of cool roofing for you. The guidelines and resources outlined here will help you design and specify the most efficient and effective cool roof.

WHAT MAKES A COOL ROOF?

The most energy-efficient roof will reflect as much solar radiation as possible, while re-radiating as much absorbed heat as quickly as possible. The “coolness” of a roof is determined by two universal surface properties.

The fraction of solar energy that is reflected by a material is called the solar reflectance, and is reported as a value between zero and 1. The relative ability of a roof surface to reradiate any absorbed heat is called its thermal emittance, which also is reported as a value between zero and 1. Look for the highest possible values for both properties, though most materials, excluding bare shiny metals, will have a relatively high thermal emittance. (See Figure 1.)


Figure 1. Solar reflectance and thermal emittance values are used to measure the effectiveness of a cool roof.

Another metric often used is the solar reflectance index, or SRI. The SRI of a product is a calculation combining solar reflectance and thermal emittance into one simplified value that is typically between zero and 100, with poor products rating in the negatives, and the coolest products rating above 100.

The solar reflectance, thermal emittance, and SRI values are the key to choosing the most energy-efficient roofing material for a project. They also are important because many building codes and voluntary programs, such as Malaysia's Green Building Index (GBI) or U.S. Green Building Council’s LEED rating system, require that new or retrofit projects include cool roofing with minimum solar reflectance, thermal emittance, and SRI values.

Pre-painted steel manufacturers and downstream roofing-product manufacturers work with accredited laboratories and rating systems to measure and report these values to the public. Most manufacturers will have their products tested for initial values. Many also will have their samples sent to a test farm where they will be installed on racks outdoors for three years before being testing for aged values in order to get a better sense of how the product will perform over its lifetime. The initial and aged solar reflectance, thermal emittance, and SRI can often be found on manufacturers’ websites or product spec sheets, although the most reliable source is a third-party rating system.

WHY CHOOSE A COOL ROOF?

When chosen and installed properly, cool roofs provide a range of benefits. One of the most environmentally promising benefits of cool roofs is their ability to help mitigate the urban heat-island effect, a phenomenon that increases urban temperatures over surrounding rural areas due to a concentration of dark, manmade materials that readily absorb and store solar energy for prolonged periods of time. Cool roofs help improve urban conditions by the following:

  • Immediately reflecting solar radiation back into the atmosphere before it can be absorbed and degraded to heat.

  • Indirectly reducing the use of air conditioning by lowering ambient air temperature.

  • Improving grid stability by increasing peak energy savings at the hottest times of the year.

  • Improving air quality and reducing heat- and smog-related illnesses such as asthma and heat stroke by lowering the ambient temperature.

In a 2010 report, “Global Cooling: Policies to Cool the World and Offset Global Warming from CO2 Using Reflective Roofs and Pavements,” the Lawrence Berkeley National Laboratory in Berkeley, Calif., speculated that worldwide implementation of reflected roofing in urban areas can produce a global cooling effect equivalent to offsetting 24 gigatons of CO2 over a 20-year use of those roofs. That is equivalent to taking 300 million cars off the road and amounts to $600 billion in energy savings.

There are many immediate, building-scale benefits owners and designers can expect by specifying a cool roof. These include the following:

  • Improved occupant comfort because of lower building temperatures directly below the roof, especially on unconditioned spaces such as warehouses and attics.

  • Energy savings from reduced cooling energy loads.

  • Longer air-conditioning unit life due to decreased use.

  • Increased roof durability due to reduced thermal flux.

Cool roofs often complement other green-building strategies such as solar photovoltaic panels. In fact, cool roofs can actually increase the efficiency of PV panels by maintaining a cooler, more optimal performance temperature underneath rooftop photovoltaic arrays. Cool metal roofing also is ideal for water-harvesting projects. In a study completed in January 2011 by the Cockrell School of Engineering at the University of Texas at Austin, researchers found that metal roofing produced one of the highest levels of harvested water quality for indoor use.

Metal-roofing manufacturers long ago developed cool-colored coatings with light-reflecting pigments that increase solar reflectance by reflecting light in the near infrared spectrum, which is where half of the sun’s energy resides. These cool color products are more reflective than their standard counterparts, with a reflectance of, for example, 0.4 versus 0.09. There may be a slight price premium on these products, so designers may also choose to use a lighter-colored standard product. New technologies are continually emerging, such as directionally reflective products. These stepped metal panels have a white or light-colored coating on the horizontal surfaces and a colored surface on the vertical surfaces. The roof appears white from the sun’s angle above and colored from the street level. Again, the energy efficiency of a roof depends on its solar reflectance and thermal emittance, not merely by its labelling as a cool product.
