Energy Policy

Energy is a critical component of achieving sustainable development. In addition to the three aspects of promoting access, renewables, and efficiency, the dimension of resilience in energy systems should also considered. The implementation of resilient energy systems requires a quantitative understanding of the socio-economic practices underlying such systems. Specifically, in line with the increasing globalization of trade, there remains a critical knowledge gap on the link between embodied energy in the production and consumption of traded goods. To bridge this knowledge gap, we investigate the resilience of global energy systems through an examination of a diversity measure of global embodied electricity trade based on multi-regional input-output (MRIO) networks. The significance of this research lies in its ability to utilize high resolution MRIO data sets in assessing the resilience of national energy systems. This research indicates that secure and responsible consumption requires the diversification of not only energy generation but also energy imports. This research will lay the ground for further research in the governance of resilience in global energy networks. © 2015 Elsevier Ltd. Source

This study examines, with a focus on regional environmental states in China, whether regional latecomers suffer the domestically created pollution haven effect through the interjurisdictional competition for polluted industries within China, or enjoy the spillover effect of nationwide progress in environmental management and technology, using the analytical framework of the environmental Kuznets curve. The study found that the regional latecomer's advantage was verified in the case of wastewater, while its disadvantage was identified in waste gas and solid waste. We speculate that the contrasting result on regional latecomer's effects between wastewater, waste gas, and solid waste comes from the difference in policy performances: the well-designed water pollution control may have regional latecomer's enjoy the spillover effect of nationwide progress, while the ineffective control of air and solid waste pollution may cause a pollution haven effect through the interjurisdictional competition for polluted industries on regional latecomers. © 2010 Cambridge University Press.

Smart meters, in conjunction with time-of-use (TOU) pricing, can facilitate an improvement in energy efficiency by providing consumers with enhanced information about electricity consumption and costs, and thereby encourage a shift away from consumption during peak hours. In 2009-10, the Irish Commission for Energy Regulation co-ordinated a randomised controlled trial in the Irish residential electricity market. Smart meters were introduced in approximately 5,000 households, divided into control and treatment groups, with treatment groups exposed to a variety of TOU tariffs and information stimuli. This paper analyses the response of Irish households at different times of the day to the introduction of TOU tariffs and information stimuli. We find that these measures have a significant effect in reducing electricity consumption in Ireland, particularly during peak hours. However, while households reduce peak demand significantlyafter the introduction of TOU tariffs and associated information, there is little incremental response to increasing differentials between peak and off-peakprices. © 2014 by the IAEE.
