Combined Heat and Power Systems

Combined Heat and Power (CHP), or Cogeneration, is the sequential or simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) in a single, integrated system. In conventional electricity generation systems, about 35% of the energy potential contained in the fuel is converted on average into electricity, whilst the rest is lost as waste heat. CHP systems uses both electricity and heat and therefore can achieve an efficiency of up to 90%, giving energy savings between 15-40% when compared with the separate production of electricity from conventional power stations and of heat from boilers. CHP systems consist of … Continue reading

Sustainability in the Middle East: Complications and Opportunities

The Middle East region is facing a unique set of natural, operational, political, economic and social challenges in efforts to adopt sustainability. The rapid development and increasing population in these countries have led to an increased consumption of fossil fuels, water, and other non-renewable natural resources, taking a toll on the environment. Though the Middle East countries have significantly contributed to the carbon emissions, over the past decade they have taken positive steps towards addressing the core environmental issues and improving sustainability situation in their respective countries. This article aims at sharing the common challenges and opportunities faced by the … Continue reading

Sustainability Reporting in the Middle East

The concept of sustainability centers on a balance of society, economy and environment for current and future health. Responsible resource management in all three areas ensures that future generations will have the resources they need to survive and thrive. One way that companies can consider sustainability and social responsibility is by focusing on the triple bottom line, which is an expanded baseline for measuring financial, social and environmental performance. It is also referred to as “People, Planet and Profit.” The advantages enjoyed by an organisation that implements sustainable management include higher efficiency and competitiveness, increased financial returns and reduced risk for shareholders, attraction … Continue reading

Managing Water-Energy Nexus For Better Tomorrow

Water is an essential part of human existence, green source of energy production and input for thermal power generation. The world’s 7 billion people are dependent on just 3% (called freshwater) of the total volume of water on earth. The MENA region is home to 6.3 percent of world’s population but has access to measly 1.4 percent of the world’s renewable fresh water. Due to burgeoning population and rapid economic growth, the per capita water availability is expected to reduce to alarming proportions in the coming decades. The demand for water is expected to increase significantly in future, which is also … Continue reading

Towards New Partnerships in Water Management

Market-exchange economy and territory-bound nation state were not designed to accommodate a communication revolution that can envelop the globe and connect everyone and everything on the planet simultaneously. The result is that we are witnessing the birth of a new economic system and new governing institutions that are as different from market capitalism and the modern territorial state as the latter were from the feudal economy and dynastic rule of an era ago. Markets, in effect, are linear, discrete and discontinuous modes of operation. The new communications technologies and partnerships, by contrast, are cybernetic, not linear. The operational assumptions that … Continue reading

خواص الأبنية الخضراء

المبني الأخضر هو المبنى الذي يراعي الاعتبارات البيئية في كل مرحلة من مراحل البناء، وهي التصميم، التنفيذ، التشغيل والصيانة، والاعتبارات الرئيسية التي تراعى هي تصميم الفراغات وكفاءة الطاقة والمياه، وكفاءة استخدام الموارد، وجودة البيئة الداخلية للمبنى، وأثر المبنى ككل على البيئة.الفرق الرئيسي بين المباني الخضراء والمباني التقليدية هو مفهوم التكامل، حيث يقوم فريق متعدد التخصصات من المتخصصين في البناء بالعمل معا منذ مرحلة ما قبل التصميم الي مرحلة ما بعد السكن لتحسين خواص الاستدامة البيئية للمبنى وتحسين الأداء والتوفير في التكاليف. المباني الخضراء توفر العديد من المزايا للعديد من الجهات المعنية بصناعة البناء، بما في ذلك سكان المباني والمجتمع ككل.المباني … Continue reading

Peak Oil: Perspectives for Saudi Arabia

The term ‘peak oil’ is ominous to the Middle East, as most of the countries in the region are heavily dependent on oil and natural gas for industrial, economic and social development. Petroleum is considered one of the world’s most important sources of energy generation, after uranium, of course. Many other substances have been tested in order to be used as alternatives to petroleum, but none have hitherto been successful. Scientific research illustrates how the world is facing catastrophe if it doesn’t find an alternative to oil, as it is currently impossible for the global economy to grow without sufficient amounts … Continue reading

Renewable Energy in the Middle East

The Middle East energy sector has played and will continue to play an important role in the regional as well as global economy. The oil and gas sector is the largest economic sector in the region. In addition to satisfying energy needs for economic and social development, it is the source of oil and gas export revenues contributing to economic development. Regional countries are heavily dependent on oil and gas to meet their domestic energy demand. Oil contributes more than half of the total energy demand in the Middle East while the rest is contributed by natural gas. Widespread use … Continue reading

Vanishing Aquifers in MENA

Aquifers are of tremendous importance for the MENA as world’s most water-stressed countries are located in the region, including Kuwait, Qatar, UAE, Palestine, Saudi Arabia, Oman, Iran, Lebanon and Yemen. However, aquifers in MENA are coming under increasing strain and are in real danger of extinction. Eight aquifers systems, including those in MENA, are categorized as ‘over stressed’ aquifers with hardly any natural recharge to offset the water consumed. Aquifers in MENA Aquifers stretched beneath Saudi Arabia and Yemen ranks first among ‘overstressed’ aquifers followed by Indus Basin of northwestern India-Pakistan and then by Murzuk-Djado Basin in North Africa. The Nubian Sandstone Aquifer in … Continue reading

Say ‘No’ to Disposables

The waste quantities in all parts of the world are increasing many folds. In the past three decades, the waste quantities have almost been doubled. The per capita waste generation is alarmingly high especially in GCC countries. The municipal and governmental authorities have to spend huge resources in collection, storage, transportation, treatment and disposal of these wastes. With limited recycling facilities and absence of reusing culture, more quantities of the waste is now to be managed. Major part of our municipal waste is still heading towards our landfill sites where it is being dumped, compacted and covered. The landfills are … Continue reading
