“…Simulation and optimization are also used, primarily to assess the potential impacts of a policy change. Notable examples include the effect of urban form on energy use for water systems [225], predicting greenhouse-gas emissions for a Japanese city [226,227], and the impact of transportation system changes [228][229][230][231][232].…”

“…This creates a challenge for the modeller, who must assess the quality of the available data source and determine whether or not it is sufficient to answer their research question. In developing countries in particular, acquiring any urban energy statistics can be difficult although there were some exceptions within the data set including the energy consumption of bakeries in Nigeria [282], gasoline consumption in Mexico [231], and industrial combustion in Brazil [211]. Improving the availability of data on developed country cities is particularly important because the UN and IEA forecast that, in the coming decades, urban population and energy service demand will grow most quickly in these regions.…”

Energy use in cities has attracted significant research in recent years. However such a broad topic inevitably results in number of alternative interpretations of the problem domain and the modelling tools used in its study. This paper seeks to pull together these strands by proposing a theoretical definition of an urban energy system model and then evaluating the state of current practice. Drawing on a review of 219 papers, five key areas of practice were identified -technology design, building design, urban climate, systems design, and policy assessment -each with distinct and incomplete interpretations of the problem domain. We also highlight a sixth field, land use and transportation modelling, which has direct relevance to the use of energy in cities but has been somewhat overlooked by the literature to date.Despite their diversity, these approaches to urban energy system modelling share four common challenges in understanding model complexity, data quality and uncertainty, model integration, and policy relevance. We then examine the opportunities for improving current practice in urban energy systems * Corresponding author Email addresses: j.keirstead@imperial.ac.uk (James Keirstead), m.jennings09@imperial.ac.uk (Mark Jennings), a.sivakumar@imperial.ac.uk (Aruna Sivakumar) Preprint submitted to Renewable and Sustainable Energy ReviewsOctober 5, 2011modelling, focusing on the potential of sensitivity analysis and cloud computing, data collection and integration techniques, and the use of activity-based modelling as an integrating framework. The results indicate that there is significant potential for urban energy systems modelling to move beyond single disciplinary approaches towards a sophisticated integrated perspective that more fully captures the theoretical intricacy of urban energy systems.

“…The main objective of the research is determining the economic benefit in the vehicles used in two sugar mills for the transportation of operational, technical, and administrative personnel. An economic and environmental benefit is expected as a result of this research (Garcia, Manzini & Islas, 2010;Hoekman, 2009;Andress, Nguyen & Das, 2011;Demirbas, 2008;Agudelo, Muñoz & Trujillo, 2000).…”

Análisis financiero del etanol como combustible principal en dos ingenios azucareros en Colombia AbstrActIntroduction. On this paper, the results of studying the economic benefit obtained by using vehicles -fueled with different ethanol concentrations-for the transportation of the operative, technical, and administrative personnel in two sugar mills, are presented. Data from the production costs of two sugar mills in Colombia were used in the study. Objetive. To determine the economic benefit of using

“…Costa y Sodré [21] investigaron etanol hidratado como único comburente y una mezcla E22 en un MCI-EP con una cilindrada de 1.000 cm 3 , de inyección directa, refrigerado por agua, variando la relación de compresión de 10:1 a 12:1 para diferentes rpm. Encontraron que el torque, BMEP y la potencia neta de salida son mayores al utilizar la relación de compresión de 12:1, para ambos combustibles especialmente a altas velocidades.…”

En este artículo se presenta una revisión bibliográfica acerca del uso de etanol como combustible en motores de combustión interna de encendido provocado (MCI-EP). Este empieza por una breve descripción de las diversas formas de producción y principales productores en el mundo de etanol, para posteriormente profundizar en el desempeño, combustión y las emisiones en MCIEP al operar con diferentes mezclas de etanol y gasolina convencional. Los resultados obtenidos por los diferentes autores de los parámetros de desempeño, combustión y emisiones, como potencia, torque, presión media efectiva al freno (BME), eficiencia térmica, tasa de liberación de calor, eficiencia de combustión, presión en la cámara de combustión y emisiones reguladas (NOx, THC, CO, CO2 y MP), muestran que el etanol es un excelente comburente para utilizarse en mezcla con gasolina, especialmente en relaciones superiores al 20 % en volumen (E20); debido a que se produce un mejor proceso de combustión causado por el aumento en la cantidad de oxígeno, y se logran así mejoras en los parámetros de desempeño y emisiones del MCI, tales como incrementos en la potencia y la eficiencia térmica y disminución de las emisiones de CO y THC. Sin embargo, se generan aumentos en algunas emisiones contaminantes, como el CO2 y los NOx causados por el exceso de oxígeno en la combustión y el incremento de la temperatura de los gases de escape.
