Sheraton Hotels looks to SA Company for solar power

[img:Shera_0.jpg| ]24 May 2012 - A member of the Sustainable Energy Society of Southern Africa (Sessa), Pacific Solar Technologies has provided the collectors for an ambitious solar water heating project in China. According to the company’s Sarel Joubert, some 330 m2 of non-pressurised solar collectors were installed for the Sheraton Hotel in Jinan, the capital of Shandong province in Eastern China, to bring the total area to 660 m2.

Depleting crude oil reserves drive natural gas industry

[img:Gas.thumbnail.jpg| ]24 May 2012 - With the reserve-production ratios of developed nations such as the United States and Canada reaching alarming levels, and Middle Eastern resources depleting rapidly, there is widespread concern over crude oil future fuel replacement, according to a new report by natural resources research group GBI.

The report shows that while natural gas was not considered a utility in crude oil production’s glory days, the depletion of conventional crude oil reserves and regulatory emissions charges have started shifting consumption towards cleaner and more plentiful natural gas. This will therefore create a steady increase in gas demand.

The case for smart metering in Africa

]24 May 2012 - Smart Metering (SM), is an important tool in the management and improvement of energy efficiency on a global scale. New metering technologies have been introduced all over the world to deal with energy (electricity, gas and heat) shortages, meter reading problems, revenue protection processes, customer service improvement and a host of other business-related issues.  Coupled to this, many governments and energy regulatory bodies are introducing legislation to enforce the deployment of SM systems. This is a complex and technically demanding process involving role-players from various backgrounds, such as engineering, finance, legislation, customer care and political intervention.

World’s biggest platinum producer pushes fuel cell technology

[img:SusanShabangu_0.jpg| ]23 May 2012 - During May 2012, South African platinum mining group Anglo American Platinum launched a platinum-based fuel cell powered mine locomotive prototype. The project was delivered in collaboration with Vehicle Projects, Trident South Africa, and Battery Electric, and will see this partnership construct five fuel cell locomotives which will be tested for underground use at one of Anglo American Platinum’s mines.

External sun diffusers reduce energy usage

[img:sun%20diffusers_0_0.JPG| ]23 May 2012 - The Energy Efficiency Manual, written by D. R. Wulfinghoff in 1999, refers to the potential reduction in cooling load using external sun diffusers. His studies show that by installing external sun diffusers, companies can achieve a savings potential of about 70% to 95% of the cooling load. Since effective external shading blocks mostly direct sunlight, while at the same time admitting indirect light, this typically reduces solar heat input by 80% to 90%. In turn, this decreases the dependence on air conditioning to cool internal environments, which as a consequence results in both decreased operational costs and environmental impact.
