This issue has emerged with a strong energy theme, not only because of our newly named ‘Power, energy and energy management feature', but also in the Pumping and Transport features. I have been throwing words around to succinctly express future-energy scenario. A limited energy era? A constrained electricity era? A time of expensive electricity? The phrase ‘a carbon constrained world' is now widely used but the ‘power constrained world' is perhaps just as relevant. The application by Eskom for a US$3,75-billion project loan from the World Bank clearly highlights the financial constraint side of our energy future.
In defending this proposed loan, Barbara Hogan points out that the loan has three components: a large, US$3,05 chunk for Medupi, a smallish chunk (6,9%) for renewable, and a bigger, smallish chunk (13%) for energy efficiency and power plant efficiency improvements.

Pump systems, pipes and valves In our pumping feature, we talk to Larry Bachus about pump efficiency and how to properly manage pumps in order to achieve substantial efficiency gains. We also publish the paper by Willem van der Westhuizen and Tony Cattaert of Eskom about the selection and optimisation of drive options for the condensate extraction and boiler feed pumps for Medupi and Kusile. Demand and supply side energy management Our Energy feature covers the launch of Hatch Energy Africa and discusses the perspectives of our energy future, including thermal energy, nuclear and renewable. Also, DCD and Westinghouse talk to us about nuclear energy and the new MoU signed to reintroduce nuclear manufacturing to SA. Modern transport and vehicle solutions On the transport side we feature the new generation, four-cylinder, twin-turbo diesel engine from Mercedes-Benz, and in the Innovative spot, we feature the Joule electric vehicle, the South African designed EV launched as a pre production vehicle at Geneva and to be manufactured in Port Elizabeth.
