The dependence of power consumption of pneumatic conveying systems upon bulk material properties, pipeline bore and routing, and mode of flow

In this paper the dependence of the power consumption of pneumatic conveyors upon conveyed materials, pipeline route and bore, and mode of flow has been examined. The findings are that, with different materials and modes of flow, not only is the amount of power consumed very different but it varies in different ways with pipe bore and routing. Additionally it has been found that, for any given conveying system, the choice of air mover also has a strong influence on the power requirement.

Memorandum submitted by the University of Greenwich: are the consumer price increases for electricity imposed in January 2008 justified?

This paper examines whether increases to published wholesale prices justify the retail electricity price increases imposed on residential consumers in January 2008. The study is based on analysis of two questions: Is the reported wholesale price a reliable indicator of the cost electricity retailers are paying to buy power; and is the corporate structure of the British electricity sector competitive?

Global experience with electricity liberalisation

This paper examines global experiences with electricity liberalisation relevant to the new legislation on electricity passed by the Indonesian parliament in September 2009. It covers experiences in the UK, EU, USA and ten major developing economies. Finally, the paper comments on a number of the issues emerging from this survey, in particular the reliance on public finance for extensions to electricity networks, the advantages of public finance for cheaper capital and for developing renewables, and the comparative evidence on efficiency.
