The processes within simplified laboratory cylindrical beds of specially reconstituted oil sand during oil recovery are described. The beds contained a small diameter cylindrical axial passage of high permeability representing a fracture where hot vitiated air of known composition was fed...

With more than half the world's population living in urban areas, cities have become a major source of local and global atmospheric pollution. Originally developed in the 1990s to decrease local pollution, Local Emission Trading Schemes (ETSs) are now emerging as a promising cost-efficient...

The paper presents some aggregated technological, economic and environmental indicators of a national energy efficiency programme for Bulgaria. The programme, elaborated by a large inter-disciplinary team and approved by all ministries, covers macroeconomic and branch dynamics, industry,...

In November 2002, the Chinese government declared that, in the next two decades, China would concentrate on building a XiaoKang Shehui, or well-off society. Naturally, we would doubt whether China's GDP could still quadruple while its energy use only doubled in the next two decades, similar to...

This paper presents an analysis of the prospects for nuclear energy development in the Eastern European countries of Belarus and Ukraine and in the Caucasian countries of Armenia, Azerbaijan and Georgia. The main focus is on Ukraine, but some reference is made to the prospects for energy...

This paper discusses whether recent energy trends are compatible with the requirements of sustainable development. For this purpose, using decomposition analysis, we derive a few long-term sustainability conditions for the energy system and examine whether they are satisfied on the basis of the...

The analysis of US foreign energy policy should be in the context of a 'grand strategy' choice between 'global hegemonism' and 'cooperative realism'. The latter is more viable in addressing a series of global systemic crises. The first of these crises is in the global security system itself as...

Global warming is a universal problem nowadays. The recent United Nations Climate Change Conference in Copenhagen was partially successful because all participating countries realised the damages caused by greenhouse gas (GHG) emissions and promise to mitigate in the future course of time. India...

The Swiss Association of Producers and Distributors of Electricity (VSE) identified a number of possible supply mix options to meet the future electricity demand in Switzerland. In this context, PSI, in co-operation with ETHZ, analysed environmental inventories for the selected electricity...
