الذروة النفطية…..بين النظرية و الواقع

  يعد النفط اليوم من أهم مصادر توليد الطاقة في العالم، بالطبع بعد اليورانيوم، وقد تم وضع الكثير من المواد تحت التجربة لتكون بديلآ للنفط و لكن لم تتك بالنجاح إلى يومنا هذا.و السبب الرئيس لذلك هو فقدانها الكثافة التي يتمتع بها النفط، فضلا عن أنها لا تحقق معدلات العائد التي يحققها الإستثمار في إستكشاف وإنتاج النفط،. وهناك أيضآ أبحاث علمية تشير إلى أن العالم مقدم على كارثة إذا لم يتوصل لمصدر بديل له، حيث لا يمكن للإقتصاد العالمي أن ينمو حاليآ بدون وجود كميات كافية من الطاقة تتماشى مع إحتياجات هذا النمو. وتتزايد النقاشات اليوم أكثر من أي وقت مضى … Continue reading

Significance of Domestic Water Conservation

The Middle East region is plagued by water scarcity and water management issues. Despite heavy investment in the water sector, water management remains a serious economic and environmental issue throughout the region. Overconsumption of water is a serious issue as per capita use of water in most of the Middle Eastern countries is several times more water than the global average. For example, on an average each UAE and Saudi Arabian resident consume 550 liters and 250 liters of water per day respectively. On the other hand, per capita water consumption in United Kingdom and Germany is 150 liters and … Continue reading

Smart Grid – Key to Managing Energy Demand in Saudi Arabia

Electricity consumption in the Kingdom of Saudi Arabia has been climbing steadily for the past few decades. Saudi electricity market is growing at an accelerating rate due to higher consumption rates in the private, commercial and industrial sectors. Current domestic energy consuming behaviors pose inescapable fatal consequences that affect both the Kingdom’s production and export levels. Therefore, an urgent action is needed to curb the increasing electricity demand and promote energy conservation in the country. Smart grid is a dynamic solution which can bridge the gap between the current supply and increasing demand in Saudi Arabia. What is Smart Grid? A … Continue reading

Environmental Research in Arab World: Perspectives

The Arab world is facing many environmental pressures ranging from challenges in resource management and water scarcity to air pollution and climate change, which all require serious scientific research. Arab nations contribute 1.7 percent of the total value of budgets embarked for environmental research worldwide. Leaders in Environmental Research Egypt, Saudi Arabia, Morocco and Tunisia are the most active research countries in general science and environmental research. Scientific research has increased in the last ten years, with Egypt leading the Arab world, followed by Saudi Arabia for both the number and rate of publications produced. Egypt has contributed at least … Continue reading

My Little Paper Recycling Project

Paper industry is considered as one of the world’s largest consumers of fossil fuels and biggest industrial polluter. The industry is criticized by environmental groups for being responsible for massive deforestation around the world. With the use of modern technology such as the printing press and the highly mechanised harvesting of wood, paper has become a cheap commodity. This has led to a high level of consumption and waste. Worldwide consumption of paper has risen by 400% in the past 40 years, with 35% of harvested trees being used for paper manufacture.  Paper wastes constitute as much as one-fourth of the solid … Continue reading

Waste Management in Jeddah

Jeddah, a major commercial hub in the Middle East, is the second largest city in Saudi Arabia. Solid waste management is a big problem in Jeddah as the city’s population is increasing at a rapid pace and has now touched 3.5 million. More than 5,000 tons of solid waste is produced every day and Jeddah municipal authorities are finding it increasingly hard to cope with the problem of urban waste. The management of solid waste in Jeddah begins with collection of wastes from bins scattered across residential and commercial areas. Wastes is collected and sent to transfer stations from where it … Continue reading

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

Waste Management Perspectives for Saudi Arabia

Solid waste management is a big challenge for the government and local authorities in the Kingdom of Saudi Arabia. The country generates more than 15 million tons of municipal waste each year with vast majority diverted to landfills and dumpsites. Recycling, reuse and energy recovery is still at an early stage, although they are getting increased attention. Recycling rate ranges from 10-15%, mainly due to the existence of the informal sector which extracts recyclables from municipal waste stream. Waste management issues in the Kingdom can be resolved by creating a healthy general environment specifically targeting the waste sector which may … Continue reading

Towards a Green Hajj

Despite the spiritual perfection of the rites of the Hajj pilgrimage, there are some deep issues with its practical implementation. In a journey where one is meant to recalibrate one’s consciousness of the one true Creator, it seems paradoxical that such an excursion should lead to environmental harm (or destruction). Why is it then that I walk the street of the Haram (sacred land) and find them littered with boxes of chicken and rice, strewn on the curb in front of beggars who offer to pray for you in exchange of spare change? A Deluge of Waste In 7:31, the … Continue reading
