Energy efficiency, which is one of the pillars of the EU's Energy Union strategy, has been proposed as a solution, namely as a highly effective pathway to improve economic competitiveness and ...sustainability of the European economy, lower emissions, reduce energy dependency and increase security of supply, and job creation. The paper reviews the EU strategies and policies on energy efficiency and argues that further focus should be placed on industrial energy efficiency. Despite a decline in energy consumption in recent years in industry, this sector is one of the largest users of energy in the EU. Therefore, the paper reviews the extent to which the European and national policies in the selected jurisdictions, such as Italy and the UK address energy efficiency in industry and whether there are any measures in place to promote it.
•Legal certainty is required in industrial energy efficiency policies.•White Certificates play a major role in industrial energy efficiency in Italy.•Yet, constant changes in the WC regulations can act as an investment barrier.•The UK's Energy Efficiency policy is underpinned with decarbonisation of the industry.
Poorly implemented energy subsidies are economically costly to taxpayers and damage the environment. This report aims at providing the emerging lessons form a representative sample of case studies in ...20 developing countries that could help policy makers to address implementation challenges, including overcoming political economy and affordability constraints. The sample has selected on the basis of a number of criteria, including the countrys level of development (and consumption), developing country region, energy security and the fuel it subsidies (petroleum fuel, electricity, natural gas). The case studies were supported by data collection related to direct budgetary subsidies, fuel and electricity tariffs, and household survey data.The analysis provides strong evidence of the success of reforms in reducing the associated fiscal burden. For the sample of countries, the average energy subsidy recorded in the budget was reduced from 1.8% in 2004 to 1.3%GDP in 2010. The reduction of subsidies is particularly remarkable for net energy importers. Pass-through of international fuel prices was also notable in the case of electricity generated by fossil fuel. For the sample of countries, the average end-user electricity tariff increased by 50%, from USD 6 cents in 2002 to USD 9 cents per kWh in 2010.In spite of the relatively price inelastic demand for gasoline and diesel, fossil fuel consumption in the road sector (per unit of GDP) declined in the 20 countries examined from 53 (44) in 2002 to about 23 kt oil equivalent per million of GDP in 2008 in the case of gasoline (Diesel). The most notable decline in consumption was recorded in the low and lower middle income countries. This reflects the much higher rate of growth in GDP in this group of countries and underlines the opportunities to influence future consumption behavior rather than modifying
the existing consumption patterns, overcoming inertia and vested interests. Similar trends are recorded for power consumption.While there is no one-size-fits-all model for subsidy reform, implementation of compensatory social policies and an effective communication strategy, before the changes are introduced, reduces helped with the implementation of reforms.
Hydrofluorocarbons (HFCs) have important applications in different industries; however, they are environmentally unfriendly due to their high global warming potential (GWP). Hence, reclamation of ...used hydrofluorocarbons via energy-efficient adsorption-based separation will greatly contribute to reducing their impact on the environment. In particular, the separation of azeotropic refrigerants remains challenging, such as typical mixtures of CHsub.2Fsub.2 (HFC-23) and CHFsub.3 (HFC-32), due to a lack of adsorptive mechanisms. Metal–organic frameworks (MOFs) can provide a promising solution for the separation of CHFsub.3–CHsub.2Fsub.2 mixtures. In this study, the adsorption mechanism of CHFsub.3–CHsub.2Fsub.2 mixtures in TIFSIX-2-Cu-i was revealed at the microscopic level by combining static pure-component adsorption experiments, molecular simulations, and density-functional theory (DFT) calculations. The adsorption separation selectivity of CHsub.2Fsub.2/CHFsub.3 in TIFSIX-2-Cu-i is 3.17 at 3 bar under 308 K. The existence of similar TiFsub.6 sup.2− binding sites for CHsub.2Fsub.2 or CHFsub.3 was revealed in TIFSIX-2-Cu-i. Interactions between the fluorine atom of the framework and the hydrogen atom of the guest molecule were found to be responsible for determining the high adsorption separation selectivity of CHsub.2Fsub.2/CHFsub.3. This exploration is important for the design of highly selective adsorbents for the separation of azeotropic refrigerants.
This book explores energy savings performance contracts (ESPCs) as a means of overcoming some of the more difficult hurdles in promoting energy efficiency in public facilities. ESPCs represent a very ...attractive solution to many of the problems that are unique to public agencies, since they involve outsourcing a full project cycle to a service provider. From the detailed audit through implementation and savings verification, ESPCs can relieve public agencies of bureaucratic hassles, while service providers can secure the off-budget project financing and be paid from the actual energy savings, thus internalizing project performance risks. ESPC bidding also allows public agencies to select from a range of technical solutions, maximizing the benefit to the agency. Global experience suggests that ESPCs have been more effective at realizing efficiency gains than many other policy measures and programs, since the service providers have a vested interest in ensuring that a project is actually implemented. Many of the country governments interviewed for the study also saw enormous potential in bundling, financing, and implementing energy efficiency projects on a larger scale in the public sector, a method that increases the rate of efficiency gains and creates further benefits through economies of scale.
El presente trabajo aborda el desarrollo de un proceso metodológico y diseño arquitectónico sostenible a partir del intercambio de información entre modelos constructivos realizados con la ...metodología BIM (Building Information Modelling) y los programas de certificación energética más comunes. Este traspaso de información constructiva ha resultado ser históricamente una tarea manual a la que el diseñador ha debido enfrentarse, a menudo, a partir de la generalización y simplificación de los modelos energéticos. Este escrito describe una metodología y aplicación web gratuita de desarrollo propio (IMIP-appweb), que permite la lectura de la información contenida en ficheros IFC y GBXML, e incorpora de forma automatizada los datos necesarios en el modelo energético, facilitando su calificación, contribuyendo a su evaluación, a la mejora de su rendimiento energético y, consecuentemente, a la reducción de su huella de carbono. La aplicación ha sido evaluada exitosamente a partir de los casos de estudio y pruebas piloto llevadas a cabo en el transcurso del proyecto IMIP (Innovative Eco-Construction System Based on Interlocking Modular Insulation Wood and Cork-Based Panels), simulados energéticamente con la ayuda de la herramienta. Esta aproximación supone una nueva estrategia en la lucha contra el cambio climático ya que: (a) reduce los tiempos de trabajo en los procesos de certificación energética; (b) facilita la interacción entre distintos modelos digitales promoviendo una toma de decisiones más informada en materia de diseño ambiental, que ha de contribuir finalmente a reducir el impacto de los edificios públicos y privados en el Sudoeste Europeo.
Over the last two decades, the European Union and its Member States have introduced policies aimed at improving energy efficiency. The Energy Service Directives (ESD) introduced the concept of ...measurement of energy savings attributed to policies. Two different and complementary methodologies for the evaluation of energy savings have been developed under the ESD: the bottom-up (BU) approach, based on a technical analysis of each measure, and the top-down (TD) approach, based on the analysis of how energy intensity changes over time. BU methods can hardly take into account policy-induced behavioural changes, whereas TD methods have difficulties in disentangling policy-induced savings from other savings. Econometric models have been proposed as a viable alternative to deal with both drawbacks. The purpose of this article is to present an econometric model aimed at estimating the energy savings induced by energy efficiency policies in the EU Member States in the period 1990–2013. We introduce an explicit measure of Energy Policy Intensity based on the MURE database, which is used as explanatory variable in a dynamic panel model for 29 European countries. Our results suggest that energy consumption in 2013 in Europe would have been about 12% higher in the absence of energy efficiency policies.

The traditional electrochemical caustic soda recovery system uses the generated pH gradient across the ion exchange membrane for the regeneration of spent alkaline absorbent from COsub.2 capture. ...This electrochemical COsub.2 capture system releases the by-products Hsub.2 and Osub.2 at the cathode and anode, respectively. Although effective for capturing COsub.2, the slow kinetics of the oxygen evolution reaction (OER) limit the energy efficiency of this technique. Hence, this study proposed and validated a hybrid electrochemical cell based on the Hsub.2-cycling from the cathode to the anode to eliminate the reliance on anodic oxygen generation. The results show that our lab-scale prototype enabled effective spent caustic soda recovery with an electron utilisation efficiency of 90%, and a relative carbonate/bicarbonate diffusional flux of approximately 40%. The system also enabled the regeneration of spent alkaline absorbent with a minimum electrochemical energy input of 0.19 kWh/kg COsub.2 at a COsub.2 recovery rate of 0.7 mol/msup.2/h, accounting for 30% lower energy demand than a control system without Hsub.2-recycling, making this technique a promising alternative to the conventional thermal regeneration technology.
