Energy shift: decline of easy oil and restructuring of geo-politics

Oliver R. INDERWILDI,David A. KING

Frontiers in Energy 2016, Volume 10, Issue 3,   Pages 260-267 doi: 10.1007/s11708-016-0416-8

Abstract: This paper critically assesses the geopolitical and geo-economic impact of novel fuel resources on both resource exporters and importers. Presently, very strong political and economic forces drive the utilisation of domestic, unconventional oil and gas recovery in the West as these enhance energy security and ease balance of payment issues. The additional capacity generated by this trend has, supported by other effects such as Saudi Arabia’s decision to maintain current production, triggered a significant reduction of oil prices. Consequently, it is now oil exporters that struggle with the balance of payment issues and often these countries base their fiscal budget completely on fossil fuel revenues. In fact, these unconventional resources help turn the tide while oil exporters are now politically significantly weakened due to the increased energy sufficiency of the West. The catch is that the extraction of unconventional types of oil has many environmental implications. So, internalising the environmental externalities have to be considered. This paper, therefore, assesses, next to geopolitics and geo-economics, the environmental implications of this trend.

Discussion on Long-Life Security Strategies for Railway Track Engineering

Wang Ping,Chen Rong and An Boyang

Strategic Study of CAE 2017, Volume 19, Issue 6,   Pages 66-71 doi: 10.15302/J-SSCAE-2017.06.010

Abstract:

Although significant progress in the development of rail transportation infrastructure has been achieved in China, operational safety management and efficient maintenance still has numerous complicated problems to be solved, especially relating to insufficient service life. Therefore, it is particularly urgent to organize and implement a long-life security plan for railway track engineering. This paper first reviews recent achievements in the field of railway track engineering in China, and then introduces advancements in this field in developed countries. Compared to developed countries, current research into long-life safety in the field of railway track engineering in China has much room for improvement; there is the absence of a top-level design, a lack of systematic research work, and insufficient depth and breadth of research. This paper concludes by providing suggestions in terms of theoretical research, talent cultivation, intelligent information management, and performance improvement and recovery.
