The Concept of Energy Management

By | | , ,
26 Comments

Energy management is the best solution for direct and immediate reduction of energy consumption for businesses and households. For the last few decades we have been exploring various alternatives to conventional sources of energy like solar, wind and biomass energy. However, due attention must also be given to best utilization of energy, improvement in energy efficiencies and optimum management of energy resources. Infact, energy management deals with already existing sources and actual consumption. It includes planning and operation of energy-related production and consumption units. The main objectives of energy management are resource conservation, environment protection and cost savings. The central … Continue reading →

District Cooling in the Middle East: Potential and Challenges

By | | , ,
2 Comments

District cooling produces chilled water in a centralized location for distribution to buildings like offices and factories through a network of insulated underground pipes. The chilled water travels to different buildings, where the water circulates through refrigeration coils or uses absorption technology to enter the air-conditioning system. During winter, the source for the cooling can often be seawater, so it is a cheaper resource than using electricity to run compressors for cooling. What is District Cooling District cooling provides effective control over internal temperature of a building, requires less maintenance than a standalone air-conditioning system, consumes lesser space and reduces … Continue reading →

Energy Efficiency Perspectives for UAE

By | | , ,
2 Comments

With Abu Dhabi alone on track to generate more than 10,000 megawatts of electricity for the first time, discussion about improving energy efficiency in the United Arab Emirates is taking on a more critical tone. Daytime energy use in the hot summer months is still experiencing rampant year-on-year growth, with peak demand this year growing by 12 per cent. Lying at the heart of these consumption levels is the need for air conditioning, which accounts for about half of total electricity demand. Business and Government Action At the commercial level, considerable steps are being taken to reduce the Emirate’s carbon … Continue reading →

Desertec: What Went Wrong?

By | | , ,
9 Comments

A plan to power Europe from solar power plants in Sahara desert, popularly known as Desertec, seems to have stalled, but several large North African solar projects are still going ahead despite local concerns. Where did the Desertec project go wrong, and can desert solar power yet play a role in a democratic and sustainable future? If you use social media, you may well have seen a graphic going around, showing a tiny square in the Sahara desert with the caption: ‘This much solar power in the Sahara would provide enough energy for the whole world!’ Can this really be true? It is … Continue reading →

Waste-to-Energy Pathways

By | | , ,
15 Comments

Waste-to-energy is the use of modern combustion and biological technologies to recover energy from urban wastes. The conversion of waste material to energy can proceed along three major pathways – thermochemical, biochemical and physicochemical. Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are rich in organic matter. 1. Thermochemical Conversion of Waste The three principal methods of thermochemical conversion of MSW are combustion (in excess air), gasification (in reduced air), and pyrolysis (in … Continue reading →

Saudi Arabia is the largest construction market in the Middle East, with large development projects under way and many more in the planning stage. The cement industry in Saudi Arabia is evolving rapidly and annual clinker production was 75 million tonnes in 2018. The cement industry is one of the highest energy-intensive industries in the world, with fuel and energy costs typically representing 30-40% of total production costs. On an average, the specific electrical energy consumption typically ranges between 90 and 130 kWh per tonne of cement. Keeping in view the huge energy demand of the cement industry, the Saudi … Continue reading →

Municipal solid waste is a poor-quality fuel and its pre-processing is necessary to convert it into fuel pellets to improve its consistency, storage properties, handling characteristics, combustion behaviour and calorific value. Technological improvements are taking place in the realms of advanced source separation of MSW, resource recovery and production of MSW fuel pellets in both existing and new plants for this purpose. There has been an increase in global interest in the preparation of MSW fuel pellets or Refuse Derived Fuel (or RDF) so let us take a close look at this interesting alternative fuel.
