Operational costs of A 13,000 solar home systems rural electrification programme

This paper presents an assessment and evaluation of the costs of operation and maintenance (O&M) in a real PV rural electrification (PVRE) programme, with the aim of characterizing its costs structure. Based on the extracted data of the 5-years operational costs of a private operator, the programme has been analyzed to take out the most relevant costs involved in the O&M phase as well as the comparative appraisal between the 3 main activities: installation, O&M and management. Through this study we try to answer to the new challenge of decentralized rural electrification based on larger programmes (with tens of thousands of SHSs) and longer maintenance and operation periods (at least 10 years).

LED bulbs technical specification and testing procedure for solar home systems

The definition of technical specifications and the corresponding laboratory procedures are necessary steps in order to assure the quality of the devices prior to be installed in Solar Home Systems (SHS). To clarify and unify criteria a European project supported the development of the Universal Technical Standard for Solar Home Systems (UTSfSHS). Its principles were to generate simple and affordable technical requirements to be optimized in order to facilitate the implementation of tests with basic and simple laboratory tools even on the same SHS electrification program countries. These requirements cover the main aspects of this type of installations and its lighting chapter was developed based on the most used technology at that time: fluorescent tubes and CFLs. However, with the consolidation of the new LED solid state lighting devices, particular attention is being given to this matter and new procedures are required. In this work we develop a complete set of technical specifications and test procedures that have been designed within the frame of the UTSfSHS, based on an intense review of the scientific and technical publications related to LED lighting and their practical application. They apply to lamp reliability, performance and safety under normal, extreme and abnormal operating conditions as a simple but complete quality meter tool for any LED bulb.

Evaluación del dispositivo Raspberry Pi como elemento de despliegue de servicios en el marco de las Smart Grids

La tendencia actual de las redes de telecomunicaciones conduce a pensar en un futuro basado en el concepto emergente de las Smart Cities¸ que tienen como objetivo el desarrollo urbano basado en un modelo de sostenibilidad que responda a las necesidades crecientes de las ciudades. Dentro de las Smart Cities podemos incluir el concepto de Smart Grid, el cual está referido a sistemas de administración y producción de energía eficientes, que permitan un sistema energético sostenible, y que den cabida a las fuentes de energía renovables. Sistemas de este tipo se muestran a los usuarios como un conjunto de servicios con los que interactuar sin ser tan sólo un mero cliente, sino un agente más del entorno energético. Por otro lado, los sistemas de software distribuidos son cada vez más comunes en una infraestructura de telecomunicaciones cada vez más extensa y con más capacidades. Dentro de este ámbito tecnológico, las arquitecturas orientadas a servicios han crecido exponencialmente sobre todo en el sector empresarial. Con sistemas basados en estas arquitecturas, se pueden ofrecer a empresas y usuarios sistemas software basados en el concepto de servicio. Con la progresión del hardware actual, la miniaturización de los equipos es cada vez mayor, sin renunciar por ello a la potencia que podemos encontrar en sistemas de mayor tamaño. Un ejemplo es el dispositivo Raspberry Pi, que contiene un ordenador plenamente funcional contenido en el tamaño de una cajetilla de tabaco, y con un coste muy reducido. En este proyecto se pretenden aunar los tres conceptos expuestos. De esta forma, se busca utilizar el dispositivo Raspberry Pi como elemento de despliegue integrado en una arquitectura de Smart Grid orientada a servicios. En los trabajos realizados se ha utilizado la propuesta definida por el proyecto de I+D europeo e-GOTHAM, con cuya infraestructura se ha tenido ocasión de realizar diferentes pruebas de las descritas en esta memoria. Aunque esta arquitectura está orientada a la creación de una Smart Grid, lo experimentado en este PFG podría encajar en otro tipo de aplicaciones. Dentro del estudio sobre las soluciones software actuales, se ha trabajado en la evaluación de la posibilidad de instalar un Enterprise Service Bus en el Raspberry Pi y en la optimización de la citada instalación. Una vez conseguida una instalación operativa, se ha desarrollado un controlador de un dispositivo físico (sensor/actuador), denominado Dispositivo Lógico, a modo de prueba de la viabilidad del uso del Raspberry Pi para actuar como elemento en el que instalar aplicaciones en entornos de Smart Grid o Smart Home. El éxito logrado con esta experimentación refuerza la idea de considerar al Raspberry Pi, como un importante elemento a tener en cuenta para el despliegue de servicios de Smart Cities o incluso en otros ámbitos tecnológicos. ABSTRACT. The current trend of telecommunication networks lead to think in a future based on the emerging concept of Smart Cities, whose objective is to ensure the urban development based on a sustainable model to respond the new necessities of the cities. Within the Smart cites we can include the concept of Smart Grid, which is based on management systems and efficient energy production, allowing a sustainable energy producing system, and that includes renewable energy sources. Systems of this type are shown to users as a set of services that allow users to interact with the system not only as a single customer, but also as other energy environment agent. Furthermore, distributed software systems are increasingly common in a telecommunications infrastructure more extensive and with more capabilities. Within this area of technology, service-oriented architectures have grown exponentially especially in the business sector. With systems based on these architectures, can be offered to businesses and users software systems based on the concept of service. With the progression of the actual hardware, the miniaturization of computers is increasing, without sacrificing the power of larger systems. An example is the Raspberry Pi, which contains a fully functional computer contained in the size of a pack of cigarettes, and with a very low cost. This PFG (Proyecto Fin de Grado) tries to combine the three concepts presented. Thus, it is intended to use the Raspberry Pi device as a deployment element integrated into a service oriented Smart Grid architecture. In this PFG, the one proposed in the European R&D e-GOTHAM project has been observed. In addition several tests described herein have been carried out using the infrastructure of that project. Although this architecture is oriented to the creation of a Smart Grid, the experiences reported in this document could fit into other applications. Within the study on current software solutions, it have been working on assessing the possibility of installing an Enterprise Service Bus in the Raspberry Pi and optimizing that facility. Having achieved an operating installation, it has been developed a driver for a physical device (sensor / actuator), called logical device, for testing the feasibility of using the Raspberry Pi to act as an element in which to install applications in Smart Grid and Smart Home Environments. The success of this experiment reinforces the idea of considering the Raspberry Pi as an important element to take into account in the deployment of Smart Cities services or even in other technological fields.

Methodology for estimating building integrated photovoltaics electricity production under shadowing conditions and case study

Building integrated photovoltaic (BIPV) systems are a relevant application of photovoltaics. In countries belonging to the International Energy Agency countries, 24% of total installed PV power corresponds to BIPV systems. Electricity losses caused by shadows over the PV generator have a significant impact on the performance of BIPV systems, being the major source of electricity losses. This paper presents a methodology to estimate electricity produced by BIPV systems which incorporates a model for shading losses. The proposed methodology has been validated on a one year study with real data from two similar PV systems placed on the south façade of a building belonging to the Technical University of Madrid. This study has covered all weather conditions: clear, partially overcast and fully overcast sky. Results of this study are shown at different time scales, resulting that the errors committed by the best performing model are below 1% and 3% in annual and daily electricity estimation. The use of models which account for the reduced performance at low irradiance levels also improves the estimation of generated electricity.

Sistema autónomo para carga de baterías mediante una instalación fotovoltaica con aplicación directa al vehículo eléctrico y usos

La situación energética actual es insostenible y como consecuencia se plantea un escenario próximo orientado a conseguir un futuro energético sostenible que permita el desarrollo económico y el bienestar social. La situación ambiental actual está afectada directamente por la combustión de combustibles fósiles que en 2013 constituyeron el 81% de la energía primaria utilizada por el ser humano y son la principal fuente antropogénica de gases de efecto invernadero. Los informes del IPCC1, ponen de manifiesto que el cambio climático se ha consolidado durante los últimos años y en la conferencia de la ONU sobre cambio climático de París que se celebrará a finales de 2015, se pretende que los gobiernos suscriban un acuerdo universal para limitar las emisiones de gases de efecto invernadero y evitar que el incremento de la temperatura media global supere los 2°C. Por otra parte, en el interior de las ciudades es especialmente preocupante, por su efecto directo sobre la salud humana, el impacto ambiental producido por las emisiones de NOx que generan el transporte de personas y mercancías. El sector del transporte fue responsable en 2012 del 27,9% del consumo final de energía. Una vez expuesto el escenario energético y ambiental actual, en esta tesis, se analiza la eficiencia de un sistema autónomo fotovoltaico para la carga de baterías de vehículos eléctricos y el uso del mismo con otras cargas, con el objetivo de aprovechar al máximo la energía eléctrica generada y contribuir a la utilización de energía limpia que no produzca impacto ambiental. Como primer paso para el desarrollo de la tesis se hizo un estudio de trabajos previos comenzando por las primeras aplicaciones de la energía fotovoltaica en los vehículos solares para después pasar a trabajos más recientes enfocados al suministro de energía a los vehículos eléctricos. También se hizo este estudio sobre las metodologías de simulación en los sistemas fotovoltaicos y en el modelado de distintos componentes. Posteriormente se eligieron, dentro de la amplia oferta existente en el mercado, los componentes con características técnicas más adecuadas para este tipo de instalaciones y para las necesidades que se pretenden cubrir. A partir de los parámetros técnicos de los componentes elegidos para configurar la instalación autónoma y utilizando modelos contrastados de distintos componentes, se ha desarrollado un modelo de simulación en ordenador del sistema completo con el que se han hecho simulaciones con distintos modos de demanda de energía eléctrica, según los modos de carga disponibles en el vehículo eléctrico para corriente alterna monofásica de 230 V. También se han simulado distintos tamaños del generador fotovoltaico y del sistema de acumulación de energía eléctrica para poder determinar la influencia de estos parámetros en los balances energéticos del sistema. Utilizando recursos propios el doctorando ha realizado la instalación real de un sistema fotovoltaico que incluye sistema de acumulación e inversor en un edificio de su propiedad. Para la realización de la tesis, La Fundación de Fomento e Innovación Industrial (F2I2) ha facilitado al doctorando un dispositivo que permite realizar la alimentación del vehículo eléctrico en modo 2 (este modo emplea un adaptador que incorpora dispositivos de seguridad y se comunica con el vehículo permitiendo ajustar la velocidad de recarga) y que ha sido necesario para los trabajos desarrollados. Se ha utilizado la red eléctrica como sistema de apoyo de la instalación fotovoltaica para permitir la recarga en el modo 2 que requiere más potencia que la proporcionada por el sistema fotovoltaico instalado. Se han analizado mediante simulación distintos regímenes de carga que se han estudiado experimentalmente en la instalación realizada, a la vez que se han hecho ensayos que se han reproducido mediante simulación con los mismos valores de radiación solar y temperatura con objeto de contrastar el modelo. Se han comparado los resultados experimentales con los obtenidos mediante simulación con objeto de caracterizar el comportamiento del sistema de acumulación (energía eléctrica suministrada y tensión de salida en las baterías) y del generador fotovoltaico (energía eléctrica fotovoltaica suministrada). Por último, se ha realizado un estudio económico de la instalación autónoma fotovoltaica ejecutada y simulada. En el mismo se ha planteado la utilización de fondos propios (como realmente se ha llevado a cabo) y la utilización de financiación, para determinar dos posibles escenarios que pudieran ser de utilidad a un propietario de vehículo eléctrico. Se han comparado los resultados obtenidos en los dos escenarios propuestos del estudio económico del sistema, en cuanto a los parámetros de tiempo de retorno de la inversión, valor actual neto de la inversión y tasa interna de retorno de la misma. Las conclusiones técnicas obtenidas, permiten la utilización del sistema con los modos de carga ensayados y otro tipo de cargas que aprovechen la generación eléctrica del sistema. Las baterías ofrecen mejor comportamiento cuando el aporte fotovoltaico está presente, pero no considera adecuado la conexión de cargas elevadas a un sistema de acumulación de gel (plomo-acido) como el que se ha utilizado, debido al comportamiento de este tipo de baterías ante demandas de intensidad de corriente eléctrica elevadas. Por otra parte, el comportamiento de este tipo de baterías con valores de intensidad de corriente eléctrica inferiores a 10 A en ausencia de energía fotovoltaica, con el objetivo de utilizar la generación de energía eléctrica diaria acumulada en el sistema, sí resulta interesante y ofrece un buen comportamiento del sistema de acumulación. Las circunstancias actuales de mercado, que carece de sistemas de acumulación de litio con precios de compra interesantes, no han permitido poder experimentar este sistema de acumulación en la instalación autónoma fotovoltaica ejecutada, tampoco se ha podido obtener el favor de ningún fabricante para ello. Actualmente hay disponibles sistemas de acumulación en litio que no se comercializan en España y que serían adecuados para el sistema de acumulación de energía propuesto en este estudio, que deja abierta las puertas para futuros trabajos de investigación. Las conclusiones económicas obtenidas, rentabilizan el uso de una instalación autónoma fotovoltaica con consumo instantáneo, sin acumulación de energía eléctrica. El futuro de conexión a red por parte de estas instalaciones, cuando se regule, aportará un incentivo económico para rentabilizar con menos tiempo las instalaciones autónomas fotovoltaicas, esto también deja la puerta abierta a futuros trabajos de investigación. El sistema de acumulación de energía aporta el mayor peso económico de inversión en este tipo de instalaciones. La instalación estudiada aporta indicadores económicos que la hacen rentable, pero se necesitaría que los precios de acumulación de la energía en sistemas eficientes estén comprendidos entre 100-200 €/kWh para que el sistema propuesto en este trabajo resulte atractivo a un potencial propietario de un vehículo eléctrico. ABSTRACT The current energy situation is untenable; it poses a scenario next focused on reaching a sustainable energy future, to allow economic development and social welfare. The environmental current situation is affected directly by the combustion of fossil fuels that in 2013 constituted 81 % of the primary energy used by the human being and they are the principal source human of greenhouse gases. The reports of the IPCC2, they reveal that the climate change has consolidated during the last years and in the conference of the UNO on climate change of Paris that will be celebrated at the end of 2015, there is claimed that the governments sign a universal agreement to limit the emission of greenhouse gases and to prevent that the increase of the global average temperature overcomes them 2°C. On the other hand, inside the cities it is specially worrying, for his direct effect on the human health, the environmental impact produced by the NOx emissions that generate the persons' transport and goods. The sector of the transport was responsible in 2012 of 27,9 % of the final consumption of energy. Once exposed the scenario and present environmental energy, in this thesis, it has analyzed the efficiency of an autonomous photovoltaic system for charging electric vehicles, and the use of the same with other workloads, with the objective to maximize the electrical energy generated and contribute to the use of clean energy that does not produce environmental impact. Since the first step for the development of the thesis did to itself a study of previous works beginning for the first applications of the photovoltaic power in the solar vehicles later to go on to more recent works focused on the power supply to the electrical vehicles. Also this study was done on the methodologies of simulation in the photovoltaic systems and in the shaped one of different components. Later they were chosen, inside the wide existing offer on the market, the components with technical characteristics more adapted for this type of facilities and for the needs that try to cover. From the technical parameters of the components chosen to form the autonomous installation and using models confirmed of different components, a model of simulation has developed in computer of the complete system with which simulations have been done by different manners of demand of electric power, according to the available manners of load in the electrical vehicle for single-phase alternating current of 230 V. Also there have been simulated different sizes of the photovoltaic generator and of the system of accumulation of electric power to be able to determine the influence of these parameters in the energy balances of the system. Using own resources the PhD student has realized a real installation of a photovoltaic system that includes system of accumulation and investing in a building of his property. For the accomplishment of the thesis, The Foundation of Promotion and Industrial Innovation (F2I2) it has facilitated to the PhD student a device that allows to realize the supply of the electrical vehicle in way 2 (this way uses an adapter that incorporates safety devices and communicates with the vehicle allowing to fit the speed of recharges) and that has been necessary for the developed works. The electrical network has been in use as system of support of the photovoltaic installation for allowing it her recharges in the way 2 that more power needs that provided by the photovoltaic installed system. There have been analyzed by means of simulation different rate of load that have been studied experimentally in the realized installation, simultaneously that have done to themselves tests that have reproduced by means of simulation with the same values of solar radiation and temperature in order the model contrasted. The experimental results have been compared by the obtained ones by means of simulation in order to characterize the behavior of the system of accumulation (supplied electric power and tension of exit in the batteries) and of the photovoltaic generator (photovoltaic supplied electric power). Finally, there has been realized an economic study of the autonomous photovoltaic executed and simulated installation. In the same one there has appeared the utilization of own funds (since really it has been carried out) and the utilization of financing, to determine two possible scenes that could be of usefulness to an owner of electrical vehicle. There have been compared the results obtained in both scenes proposed of the economic study of the system, as for the parameters of time of return of the investment, current clear value of the investment and rate hospitalizes of return of the same one. The technical obtained conclusions, they make the utilization of the system viable with the manners of load tested and another type of loads of that they take advantage the electrical generation of the system. The batteries offer better behavior when the photovoltaic contribution is present, but he does not consider to be suitable the connection of loads risen up to a system of accumulation of gel (lead - acid) as the one that has been in use, due to the behavior of this type of batteries before demands of intensity of electrical current raised. On the other hand, the behavior of this type of batteries with low values of intensity of electrical current to 10 To in absence of photovoltaic power, with the aim to use the generation of daily electric power accumulated in the system, yes turns out to be interesting and offers a good behavior of the system of accumulation. The current circumstances of market, which lacks systems of accumulation of lithium with interesting purchase prices, have not allowed to be able to experience this system of accumulation in the autonomous photovoltaic executed installation, neither one could have obtained the favor of any manufacturer for it. Nowadays there are available systems of accumulation in lithium that is not commercialized in Spain and that they would be adapted for the system of accumulation of energy proposed in this study, which makes the doors opened for future works of investigation. The economic obtained conclusions; they make more profitable the use of an autonomous photovoltaic installation with instantaneous consumption, without accumulation of electric power. The future of connection to network on the part of these facilities, when it is regulated, will contribute an economic incentive to make profitable with less time the autonomous photovoltaic facilities, this also leaves the door opened for future works of investigation. The system of accumulation of energy contributes the major economic weight of investment in this type of facilities. The studied installation contributes economic indicators that make her profitable, but it would be necessary that the prices of accumulation of the energy in efficient systems are understood between 100-200 € in order that the system proposed in this work turns out to be attractive to a proprietary potential of an electrical vehicle.

Barriers to the adoption of photovoltaic systems: The state of the art

Although photovoltaic (PV) systems have become much more competitive, the diffusion of PV systems still remains low in comparison to conventional energy sources. What are the current barriers hindering the diffusion of PV systems? In order to address this, we conducted an extensive and systematic literature review based on the Web of Science database. Our state-of-the-art review shows that, despite the rapid development and maturity of the technology during the past few years, the adoption of PV systems still faces several barriers. The wide adoption of PV systems-either as a substitute for other electricity power generation systems in urban areas or for rural electrification-is a challenging process. Our results show that the barriers are evident for both low- and high-income economies, encompassing four dimensions: sociotechnical, management, economic, and policy. Although the barriers vary across context, the lessons learned from one study can be valuable to others. The involvement of all stakeholders-adopters, local communities, firms, international organizations, financial institutions, and government-is crucial to foster the adoption.

Motivators for adoption of photovoltaic systems at grid parity: A case study from Southern Germany

In some countries, photovoltaic (PV) technology is at a stage of development at which it can compete with conventional electricity sources in terms of electricity generation costs, i.e., grid parity. A case in point is Germany, where the PV market has reached a mature stage, the policy support has scaled down and the diffusion rate of PV systems has declined. This development raises a fundamental question: what are the motives to adopt PV systems at grid parity? The point of departure for the relevant literature has been on the impact of policy support, adopters and, recently, local solar companies. However, less attention has been paid to the motivators for adoption at grid parity. This paper presents an in-depth analysis of the diffusion of PV systems, explaining the impact of policy measures, adopters and system suppliers. Anchored in an extensive and exploratory case study in Germany, we provide a context-specific explanation to the motivations to adopt PV systems at grid parity.

A review on the recent history of wind power ramp forecasting.

Forecasting large and fast variations of wind power (the so called ramps) helps achieve the integration of large amounts of wind energy. This paper presents a survey on wind power ramp forecasting, reflecting the increasing interest on this topic observed since 2007. Three main aspects were identified from the literature: wind power ramp definition, ramp underlying meteorological causes and experi-ences in predicting ramps. In this framework, we additionally outline a number of recommendations and potential lines of research.

As differential characteristics our device operates in subcritical mode, driven by a neutron source activated by an accelerator that adds clear safety advantages and fuel flexibility opening the possibility to reduce the nuclear stockpile producing energy from actual LWR irradiated fuel with an efficiency of 45?46%, either in the form of Hydrogen, electricity, or both.

Adapting micro-economy of energy corporations to macroeconomy policies aiming at a sustainable economy

Esta Tesis surgió ante la intensidad y verosimilitud de varias señales o “warnings” asociadas a políticas dirigidas a reducir el peso del petróleo en el sector energético, tanto por razones económicas, como geopolíticas, como ambientales. Como tal Tesis se consolidó al ir incorporando elementos novedosos pero esenciales en el mundo petrolífero, particularmente las “tecnologías habilitantes”, tanto de incidencia directa, como el “fracking” como indirecta, del cual es un gran ejemplo el Vehículo Eléctrico (puro). La Tesis se definió y estructuró para elaborar una serie de indagaciones y disquisiciones, que comportaran un conjunto de conclusiones que fueran útiles para las corporaciones energéticas. También para la comprensión de la propia evolución del sector y de sus prestaciones técnicas y económicas, de cara a dar el servicio que los usuarios finales piden. Dentro de las tareas analíticas y reflexivas de la Tesis, se acuñaron ciertos términos conceptuales para explicar más certeramente la realidad del sector, y tal es el caso del “Investment burden”, que pondera la inversión específica (€/W) requerida por una instalación, con la duración del período de construcción y los riesgos tanto tangibles como regulatorios. Junto a ello la Tesis propone una herramienta de estudio y prognosis, denominada “Market integrated energy efficiency”, especialmente aplicable a dicotomías. Tal es el caso del coche térmico, versus coche eléctrico. El objetivo es optimizar una determinada actividad energética, o la productividad total del sector. Esta Tesis propone varias innovaciones, que se pueden agrupar en dos niveles: el primero dentro del campo de la Energía, y el segundo dentro del campo de las corporaciones, y de manera especial de las corporaciones del sector hidrocarburos. A nivel corporativo, la adaptación a la nueva realidad será función directa de la capacidad de cada corporación para desarrollar y/o comprar las tecnologías que permitan mantener o aumentar cuota de mercado. Las conclusiones de la Tesis apuntan a tres opciones principalmente para un replanteamiento corporativo: - Diversificación energética - Desplazamiento geográfico - Beneficiándose de posibles nuevos nichos tecnológicos, como son: • En upstream: Recuperación estimulada de petróleo mediante uso de energías renovables • En downstream: Aditivos orientados a reducir emisiones • En gestión del cambio: Almacenamiento energético con fines operativos Algunas políticas energéticas siguen la tendencia de crecimiento cero de algunos países de la OCDE. No obstante, la realidad mundial es muy diferente a la de esos países. Por ejemplo, según diversas estimaciones (basadas en bancos de datos solventes, referenciados en la Tesis) el número de vehículos aumentará desde aproximadamente mil millones en la actualidad hasta el doble en 2035; mientras que la producción de petróleo sólo aumentará de 95 a 145 millones de barriles al día. Un aumento del 50% frente a un aumento del 100%. Esto generará un curioso desajuste, que se empezará a sentir en unos pocos años. Las empresas y corporaciones del sector hidrocarburos pueden perder el monopolio que atesoran actualmente en el sector transporte frente a todas las demás fuentes energéticas. Esa pérdida puede quedar compensada por una mejor gestión de todas sus capacidades y una participación más integrada en el mundo de la energía, buscando sinergias donde hasta ahora no había sino distanciamiento. Los productos petrolíferos pueden alimentar cualquier tipo de maquina térmica, como las turbinas Brayton, o alimentar reformadores para la producción masiva de H2 para su posterior uso en pilas combustible. El almacenamiento de productos derivados del petróleo no es ningún reto ni plantea problema alguno; y sin embargo este almacenamiento es la llave para resolver muchos problemas. Es posible que el comercio de petróleo se haga menos volátil debido a los efectos asociados al almacenamiento; pero lo que es seguro es que la eficiencia energética de los usos de ese petróleo será más elevada. La Tesis partía de ciertas amenazas sobre el futuro del petróleo, pero tras el análisis realizado se puede vislumbrar un futuro prometedor en la fusión de políticas medioambientales coercitivas y las nuevas tecnologías emergentes del actual portafolio de oportunidades técnicas. ABSTRACT This Thesis rises from the force and the credibility of a number of warning signs linked to policies aimed at reducing the role of petroleum in the energy industry due to economical, geopolitical and environmental drives. As such Thesis, it grew up based on aggregating new but essentials elements into the petroleum sector. This is the case of “enabling technologies” that have a direct impact on the petroleum industry (such as fracking), or an indirect but deep impact (such as the full electrical vehicle). The Thesis was defined and structured in such a way that could convey useful conclusions for energy corporations through a series of inquiries and treatises. In addition to this, the Thesis also aims at understating la evolution of the energy industry and its capabilities both technical and economical, towards delivering the services required by end users. Within the analytical task performed in the Thesis, new terms were coined. They depict concepts that aid at explaining the facts of the energy industry. This is the case for “Investment burden”, it weights the specific capital investment (€/W) required to build a facility with the time that takes to build it, as well as other tangible risks as those posed by regulation. In addition to this, the Thesis puts forward an application designed for reviewing and predicting: the so called “Market integrated energy efficiency”, especially well-suited for dichotomies, very appealing for the case of the thermal car versus the electric car. The aim is to optimize energy related activity; or even the overall productivity of the system. The innovations proposed in this Thesis can be classified in two tiers. Tier one, within the energy sector; and tier two, related to Energy Corporation in general, but with oil and gas corporations at heart. From a corporate level, the adaptation to new energy era will be linked with the corporation capability to develop or acquire those technologies that will yield to retaining or enhancing market share. The Thesis highlights three options for corporate evolution: - diversification within Energy - geographic displacement - profiting new technologies relevant to important niches of work for the future, as: o Upstream: enhanced oil recovery using renewable energy sources (for upstream companies in the petroleum business) o Downstream: additives for reducing combustion emissions o Management of Change: operational energy storage Some energy policies tend to follow the zero-growth of some OECD countries, but the real thing could be very different. For instance, and according to estimates the number of vehicles in use will grow from 1 billion to more than double this figure 2035; but oil production will only grow from 95 million barrel/day to 145 (a 50% rise of versus an intensification of over a 100%). Hydrocarbon Corporation can lose the monopoly they currently hold over the supply of energy to transportation. This lose can be mitigated through an enhanced used of their capabilities and a higher degree of integration in the world of energy, exploring for synergies in those places were gaps were present. Petroleum products can be used to feed any type of thermal machine, as Brayton turbines, or steam reformers to produce H2 to be exploited in fuel cells. Storing petroleum products does not present any problem, but very many problems can be solved with them. Petroleum trading will likely be less volatile because of the smoothing effects of distributed storage, and indeed the efficiency in petroleum consumption will be much higher. The Thesis kicked off with a menace on the future of petroleum. However, at the end of the analysis, a bright future can be foreseen in the merging between highly demanding environmental policies and the relevant technologies of the currently emerging technical portfolio.

Eco-entrepreneurship in developing countries: the case of renewable energy sector in Bolivia

The change towards a sustainable economic system represents a big challenge for the present as well as next generations. Such a process requires important long-term changes in technologies, lifestyle, infrastructures and institutions. In this scenario the innovation process is a crucial element for fostering sustainability as well as an egalitarian development in developing countries. For those reasons the concept of Eco-Innovation System is introduced and further considerations are provided for the case of less-developed countries. The paper illustrates that sustainable development is possible by exploiting local potential and traditional knowledge in order to achieve at the same time economic growth, social equality and environmental sustainability. In order to prove such an assumption a specific case study is described: The renewable energy sector in Bolivia. The case study summarizes many important dimensions of the innovation process in developing countries such as technological transfer, diffusion and adaptation, social dimension and development issues.

Environmental analysis of residential building facades through energy consumption, GHG emissions and costs

This paper provides some results on the potential to minimize environmental impacts in residential buildings life cycle, through façade design strategies, analyzing also their impact on costs from a lifecycle perspective. On one hand, it assesses the environmental damage produced by the materials of the building envelope, and on the other, the benefits they offer in terms of habitability and liveability in the use phase. The analysis includes several design parameters used both for rehabilitation of existing facades, as for new facades, trying to cover various determinants and proposing project alternatives. With this study we intended to contribute to address the energy challenges for the coming years, trying also to propose pathways for innovative solutions for the building envelope.

A review of the potential of renewable energy sources for the State of Jammu and Kashmir (India)

The future economic development trajectory for India is likely to result in rapid and accelerated growth in energy demand, with expected shortages. Many of its current policies and strategies are aimed at the improvement and possible maximization of energy production from the renewable sector. It is also clear that while energy-conservation and energy-efficiency can make an important contribution in the national energy strategy, renewable energies will be essential to the solution and are likely to play an increasingly important role for the growth of grid power, providing energy access, reducing consumption of fossil fuels, and helping India pursue its low carbon progressive pathway. However, most of the states in India, like the northernmost State of Jammu and Kashmir (J&K), have experienced an energy crisis over a sustained period of time. As India intends to be one of the emerging powers of the 21st century, it has to embark upon with these pressing issues in a more sustainable manner and accordingly initiate various renewable energy projects within these states. This paper will provide a broad-spectrum view about the energy situation within J&K and will highlight the current policies along with future strategies for the optimal utilization of renewable energy resources.

Energy- and environmentally efficient road management: The case of the Spanish motorway network

Transport is responsible for 41% of CO2 emissions in Spain, and around 65% of that figure is due to road traffic. Tolled motorways are currently managed according to economic criteria: minimizing operational costs and maximizing revenues from tolls. Within this framework, this paper develops a new methodology for managing motorways based on a target of maximum energy efficiency. It includes technological and demand-driven policies, which are applied to two case studies. Various conclusions emerge from this study. One is, that the use of intelligent payment systems is recommended; and another, is that the most sustainable policy would involve defining the most efficient strategy for each motorway section, including the maximum use of its capacity, the toll level which attracts the most vehicles, and the optimum speed limit for each type of vehicle.

Facing the climate change challenges in the mining and mineral industry as providers of a sustainable manufacturing process

A sustainable manufacturing process must rely on an also sustainable raw materials and energy supply. This paper is intended to show the results of the studies developed on sustainable business models for the minerals industry as a fundamental previous part of a sustainable manufacturing process. As it has happened in other economic activities, the mining and minerals industry has come under tremendous pressure to improve its social, developmental, and environmental performance. Mining, refining, and the use and disposal of minerals have in some instances led to significant local environmental and social damage. Nowadays, like in other parts of the corporate world, companies are more routinely expected to perform to ever higher standards of behavior, going well beyond achieving the best rate of return for shareholders. They are also increasingly being asked to be more transparent and subject to third-party audit or review, especially in environmental aspects. In terms of environment, there are three inter-related areas where innovation and new business models can make the biggest difference: carbon, water and biodiversity. The focus in these three areas is for two reasons. First, the industrial and energetic minerals industry has significant footprints in each of these areas. Second, these three areas are where the potential environmental impacts go beyond local stakeholders and communities, and can even have global impacts, like in the case of carbon. So prioritizing efforts in these areas will ultimately be a strategic differentiator as the industry businesses continues to grow. Over the next forty years, world?s population is predicted to rise from 6.300 million to 9.500 million people. This will mean a huge demand of natural resources. Indeed, consumption rates are such that current demand for raw materials will probably soon exceed the planet?s capacity. As awareness of the actual situation grows, the public is demanding goods and services that are even more environmentally sustainable. This means that massive efforts are required to reduce the amount of materials we use, including freshwater, minerals and oil, biodiversity, and marine resources. It?s clear that business as usual is no longer possible. Today, companies face not only the economic fallout of the financial crisis; they face the substantial challenge of transitioning to a low-carbon economy that is constrained by dwindling natural resources easily accessible. Innovative business models offer pioneering companies an early start toward the future. They can signal to consumers how to make sustainable choices and provide reward for both the consumer and the shareholder. Climate change and carbon remain major risk discontinuities that we need to better understand and deal with. In the absence of a global carbon solution, the principal objective of any individual country should be to reduce its global carbon emissions by encouraging conservation. The mineral industry internal response is to continue to focus on reducing the energy intensity of our existing operations through energy efficiency and the progressive introduction of new technology. Planning of the new projects must ensure that their energy footprint is minimal from the start. These actions will increase the long term resilience of the business to uncertain energy and carbon markets. This focus, combined with a strong demand for skills in this strategic area for the future requires an appropriate change in initial and continuing training of engineers and technicians and their awareness of the issue of eco-design. It will also need the development of measurement tools for consistent comparisons between companies and the assessments integration of the carbon footprint of mining equipments and services in a comprehensive impact study on the sustainable development of the Economy.
