“…It must be noted that the intracity transport energy intensity in Kawasaki and Tokyo has increased from 2010 to 2015 although the modal split has not changed much. This might be because the fossil fuel contributes to the greater share in electricity mix after the Fukushima nuclear accident [61] and this causes the increase in the transport energy intensity of electric train. Therefore, the main cause of the decrease in regression coefficient with time in 1987-2015 presented in Table 3 would be because the intracity transport energy intensity of each city continuously increased under the case of low population density while it slightly increased under the case of medium population density and remained almost the same in the case of high population density.…”

Interests in evaluating lifecycle energy use in urban transport have been growing as a research topic. Various studies have evaluated the relationship between the intracity transport energy use and population density and commonly identified its negative correlation. However, a diachronic transition in an individual city has yet to be fully analyzed. As such, this study employed transport energy intensity widely used for evaluating transport energy efficiency and obtained the transport energy intensity for each transportation means including walk, bicycle, automobile (conventional vehicles, electric vehicles, hybrid vehicles, and fuel cell vehicles), bus and electric train by considering the lifecycle energy consumption. Then, the intracity lifecycle transport energy intensity of 38 cities in Japan in 1987–2015 was computed, assuming that the cause of diachronic transition of intracity transport energy efficiency is the modal shifting and electricity mix change. As a result, the greater level of population density was associated with the lower intracity transport energy intensity in Japanese cities. The negative slope of its regression line increased over time since the intracity lifecycle transport energy intensity in cities with low population density continuously increased without any significant change of population density. Finally, this study discussed the strategic implications particularly in regional areas to improve the intracity lifecycle transport energy efficiency.

“…However, system modeling of the electrical system at the national scale by employing System Dynamics has already been validated through the comparison of the real grid in Japan [24]. This earlier research paper also conducted the parametric analysis using the real capacity of the energy source.…”

Given that a continuous power supply is fundamental to the economy and human well-being, development of a self-sustained electrical system that can withstand sudden disturbances by employing both renewable energy and storage technology is of significant importance. Most of the existing reliability approaches hardly represent a particular method of analyzing system adapting ability to remain self-sufficient in the short-term after the occurrence of sudden disruptions. In addition, existing reliability indexes are developed based on past experience, hardly covering the prediction of disruption risks. As such, a new electricity reliability quantification approach dedicated for sudden disruptions was established and the newly proposed electricity reliability prediction index was evaluated. The developed index was applied to determine optimal capacity sizing in the context of energy security. The availability of such electricity reliability predictions will allow the facility engineer to make wiser decisions to maintain a continuous power supply even after the occurrence of sudden disturbances. The developed algorithm can be readily implemented in any electrical system network including microgrid and rural electrification.

“…Sin embargo, el riesgo no es inexistente. Un accidente nuclear puede poner en riesgo el suministro de energía, lo que podría evitarse mediante la redundancia de instalaciones y la diversificación (Kosai & Unesaki, 2017), aunque encarecería la generación de energía. Más gravemente que el abastecimiento, podría resultar afectada la salud de los seres vivos en amplios rangos de distancias respecto al lugar del accidente y en varias generaciones (Lyman, 2011).…”

La energía nuclear es considerada una fuente energética útil y problemática al mismo tiempo. Su utilización ofrece ventajas e inconvenientes que deben ser analizados para comprender el dilema económico, político y social al que se enfrenta una sociedad cuando toma la decisión de configurar su perfil energético. El análisis se plantea desde una perspectiva hispano-sueca, en tanto que España y Suecia son dos ejemplos de las respuestas que una sociedad puede dar ante el mencionado dilema nuclear.
