Article 0 Reads 0 Citations Estimating Residential Electricity Consumption in Nigeria to Support Energy Transitions Published: 05 May 2018
Sustainability, doi: 10.3390/su10051440
Considering the challenge of accessing reliable household metering data in Nigeria, how can electricity consumption levels be determined? And how do disparities in electricity consumption patterns across the country affect the pursuit of sustainability, universal access and energy transition objectives? This study combined household-reported data on ownership of electrical appliances and energy expenditure with online sales records of household appliances to estimate current and future residential electricity demand in Nigeria, as well as the required generation capacity to achieve 100% electricity access, under various scenarios. Median residential electricity consumption was estimated at 18–27 kWh per capita but these estimates vary between the geographical zones with the North East and South West representing extremes. Under a universal access scenario, the future electricity supply system would be expected to have installed generation capacity sufficient to meet the estimated residential demand of 85 TWh. To further understand the required infrastructure investment as a whole and the approaches that might be preferred in rural versus urban areas, the disaggregated, zone-by-zone and urban/rural data may offer more insight than a whole-of-country approach. The data obtained is useful for identifying specific transitions at the sub-national level that can minimize the required investment while maximizing households’ energy access.
Article 0 Reads 0 Citations Provincial Carbon Emissions Reduction Allocation Plan in China Based on Consumption Perspective Published: 26 April 2018
Sustainability, doi: 10.3390/su10051342
China is a country with substantial differences in economic development, energy consumption mix, resources, and technologies, as well as the development path at the provincial level. Therefore, China’s provinces have different potential and degrees of difficulty to carry out carbon emission reduction (CER) requirements. In addition, interprovincial trade, with a large amount of embodied carbon emissions, has become the fastest growing driver of China’s total carbon emissions. A reasonable CER allocation plan is, therefore, crucial for realizing the commitment that China announced in the Paris Agreement. How to determine a fair way to allocate provincial CER duties has become a significant challenge for both policy-makers and researchers. In this paper, ecological network analysis (ENA), combined with a multi-regional input-output model (MRIO), is adopted to build an ecological network of embodied emissions across 30 provinces. Then, by using flow analysis and utility analysis based on the ENA model, the specific relationships among different provinces were determined, and the amount of responsibility that a certain province should take quantified, with respect to the embodied carbon emission (ECE) flows from interprovincial trade. As a result, we suggest a new CER allocation plan, based on the detailed data of interprovincial relationships and ECE flows.
Article 0 Reads 0 Citations Energy dependence with an Asian twist? Examining international energy relations in Southeast Asia Published: 01 November 2016
Energy Research & Social Science, doi: 10.1016/j.erss.2016.07.003
This study explores the international dimension of energy security, particularly interstate dependent relations. By developing an assessment method based on the reciprocal dependent nature of international energy interactions and the causal relations of individual energy indicators, the proposed index is applied to examine interstate energy dependence and determine whether the dependence should be considered positive, negative or mutual. Using nine Southeast Asian countries as case studies and including other relevant players involved in the dependent dynamics, the findings show interdependence in international energy relations and indicate how specific characteristics of the interactions lead to different aspects of dependent relations: external supply dependence, external demand dependence, and economic interdependence. Based on dependence levels measured by the index, symmetric and asymmetric energy dependence of the selected nine cases has been analyzed and compared, in which the results not only delineate variations of dependency status but also reflect different aspects of energy dependence in each energy product. The index has also been applied to describe bilateral energy interactions between selected countries, demonstrating how asymmetric energy dependency relations are formed and why energy import dependence is not always negative.

Article 0 Reads 1 Citation Geography, urbanization and lock-in – considerations for sustainable transitions to decentralized energy systems Published: 01 August 2016
Journal of Cleaner Production, doi: 10.1016/j.jclepro.2015.12.092
The importance of moving towards sustainable energy systems is critical to achieving societal sustainability. Transitions theory is a useful approach to look at the potential and limitations of systemic transitions, and has been applied in a number of alternative contexts. In the current study, we examine transitions theory and its implications for the progress of decentralized energy systems in Japan in the period after the Fukushima accident of 2011. Empirical data from a targeted nation-wide survey is used to examine the progress and change in consumer preference and behavior since the disaster, as possible evidence for the potential transition paths likely to be occurring. Importantly, this study utilizes data that examines a spectrum of urban-rural and disaster-non-disaster areas in order to explore whether any differences in response patterns were present. Results indicate that although the desire of stakeholders has been to change the energy system, there are barriers to transformation. Variation between rural and urban sites and between disaster-affected and unaffected areas was examined, indicating that (at least under the chosen classification) there was surprisingly little difference. The results have implications for understanding transitions at a much broader level, and imply that, if the empirical data is a useful indicator, Japan is within a locked-in or reorganization transition. In order to move to a more radical conversion type change a new approach is likely to be required to nurture niche innovations effectively.
