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

Climate Change Awareness in Jordan: An Overview

Climate change has become a global concern in recent decades and Jordan is no exception. According to IPPC, scientific evidences show that the earth experienced an average warming of around 0.7°C during the 20th century, and are projected to warm by up to 4°C by the end of the 21st century. Scientific studies reveal an increase in annual minimum air temperatures in Jordan since 1970s. The increase of mean temperature indicates a slight regional climate change, while decreasing temperature range proves that the earth is trapping terrestrial infrared radiation responsible for climate change. Besides, researchers predict further increase in the mean annual … Continue reading

Green Resolutions for the New Year

This year, in addition to our personal goals, let us make another New Year resolution: to make this year the year we really ‘go green’. Supporting environmental initiatives should be one of our main priorities and needs to be reflected through our green resolutions and commitment to safeguard it against all forms of pollution and to protect our fragile and finite resources. Depending on our age, work, location etc., our priorities may be different but our actions should be in unison towards environmental protection. We need to understand that we have very recklessly plundered the global resources in a short … Continue reading

Energy Efficiency Initiatives at the Hashemite University

The Hashemite University environmental sustainability policy is focused on achieving sufficiency and sustainability through energy reduction practices, along with energy efficient approaches, building techniques, and electromechanical devices. These measures were employed in all of the new building expansion on campus (with more than 70,000 m2) of newly added building area. These practices are divided into categories: passive and active. Passive Measures Passive energy efficiency measures focus on harnessing the natural resources in the campus area to create comfortable conditions for the campus users, especially indoors, including the following techniques used throughout the campus: Building envelope and materials: The choice of building … Continue reading

The Unending Benefits of Recycling

Recycling is the process in which used or abandoned materials from our everyday waste is converted into new products. Items that can be recycled include; glass, paper, plastics and various metals.  The process of recycling involves waste segregation after collection, processing the recyclable waste and finally manufacturing products from the waste thus processed. Why Do We Need Recycling? Manufacturing products involves obtaining raw materials from various sources. Raw materials may be from forests or mines. They are then transported to the place of manufacture usually by land or sea, which is an energy consuming process. Procurement of raw materials and their … 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

Power of Cities to Shape a Greener Future

The current rate of urbanization is one of the global megatrends, which will manifest itself in many of the challenges faced in the upcoming decades. UN reports estimate that nearly 70% of the world’s population will be urban by 2050. The way in which cities deal with this rapid rate of urbanization will determine whether international objectives such as Sustainable Development Goal 11, aimed at making cities and human settlements inclusive, safe, resilient, and sustainable, will be achieved. Urbanization has further impacts on many more of the goals defined in the UN 2030 Agenda on Sustainable Development. Achieving these goals … 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

Making a Switch to Circular Economy

All forms of wealth and security, including climate stability, biodiversity, resource availability, soil fertility, air and water purity and health, are depleted by the systemic error of running a linear economy. Linear economics consumes the basis for future growth so what is now growing fastest is unproductive activity, inactivity and instabilities. The credit crunch marks the withdrawal of faith in growth-as-usual and any reliable revival of growth and prosperity requires a switch of vision. Circular Economics The future for growth is circular economics where more economic activity would mean a faster pace of change away from waste-making and towards looking … Continue reading

Green SMEs in Middle East: Obstacles and Challenges

With ‘green’ being the buzzword across all industries, greening of the business sector and development of green skills has assumed greater importance all over the world, and Middle East is no exception. Small and medium-sized enterprises (SMEs) operating in eco-design, green architecture, renewable energy, energy efficiency and sustainability are spearheading the transition to green economy across a wide range of industries. Green SME sector in the Middle East has been growing steadily, albeit at a slower pace than anticipated. Regulations One of the major obstacles in the progress of green SMEs in the Middle East the has been poorly-designed regulation. According … Continue reading

Solar Energy Prospects in Tunisia

Tunisia is an energy-dependent country with modest oil and gas reserves. Around 97 percent of the total energy is produced by natural gas and oil, while renewables contribute merely 3% of the energy mix. The installed electricity capacity at the end of 2015 was 5,695 MW which is expected to sharply increase to 7,500 MW by 2021 to meet the rising power demands of the industrial and domestic sectors. Needless to say, Tunisia is building additional conventional power plants and developing its solar and wind capacities to sustain economic development. Wind Energy in Tunisia Wind power represents the main source of renewable energy in … Continue reading
