This paper critically reviews the range of energy efficiency indicators that can be used, particularly at the policy level.

Detailed, complete, timely and reliable statistics are essential to monitor the energy situation at a country level as well as at an international level. Energy statistics on supply, trade, stocks, transformation and demand are indeed the basis for any sound energy policy decision. The main objectives of this manual are to identify the main sectoral indicators and the data needed to develop these indicators; and to make surveying, metering and modeling practices existing all around the world available to all. This manual has been developed with a companion document, Energy Efficiency Indicators: Essentials for Policy Making, as a starting point towards enabling policymakers to understand where greater efficiency is needed, to implement appropriate policies and to measure their impact. The ultimate goal is to make improved energy efficiency not only a concept but a reality.

What is energy efficiency?: Concepts, indicators and methodological issues

This paper critically reviews the range of energy efficiency indicators that can be used, particularly at the policy level. Traditional thermodynamic indicators of energy efficiency were found to be of limited use, as they give insufficient attention to required end use services. The specific limitations and appropriate uses of physical-thermodynamic, economic-thermodynamic and pure economic indicators of energy efficiency are also considered. The paper concludes with a discussion of the per- sistent methodological problems and issues which are encountered when attempting to operational- ize all of the energy efficiency indicators. These include the role of value judgements in the construction of energy efficiency indicators, the energy quality problem, the boundary problem, the joint production problem and the question of isolating the underlying technical energy efficiency trend from the aggregate indicator.

Better monitoring and control of energy consumption and effective use of performance indicators are of utmost important for achieving improved energy efficiency performance in manufacturing for current and future enterprises. This paper aims at analyzing the current state of the art on energy related production performance indicators to derive research gaps and industrial needs in the area. The research has been conducted as preliminary step before a comprehensive effort in which the authors suggest a new methodology to develop energy related key performance indicators. Therefore, the study resulted in a clearer understanding and synthesis of the research field, gaps in scientific literature and industrial needs, hence guiding further research.

Energy intensity indicators ; Energy performance indicators. Energy efficiency indicators are statistics that quantify how efficient energy is used in various human activities. Energy plays an essential role for meeting human needs and economic development. Many studies have shown that energy consumption and quality of life are closely related. As household income rises, its energy consumption also increases. Likewise, on a per capita basis, more energy is consumed in industrial countries than in developing countries. However, it is also known that the production, transformation, distribution, and utilization of all forms of energy have, in one way or another, environmental, health, and safety impacts.

Measuring Energy Efficiency: An Application of Data Envelopment Analysis to Power Sector in Kerala

Prior research tends to propose and examine the negative relationship between market segmentation and energy efficiency. Does market segmentation necessarily impair energy efficiency? Considering the critical role that Chinaese government play in managing erergy efficiency, we propose a non-linear relationship between market segmentation and energy efficiency. Using data of 30 provinces in Mainland China during to , we find an inverse U-shaped relationship between market segmentation and energy efficiency. Our findings remain robust after controlling endogeneity issues.

Measuring Energy Efficiency: An Application of Data Envelopment Analysis to Power Sector in Kerala

Energy efficiency is widely accepted as a simple and cost-effective way to reduce energy consumption and greenhouse gas emissions. It is accordingly a corner stone of European energy and climate policies. However, in formulation of explicit political energy efficiency goals as well as in monitoring these targets, discussions arise both concerning the concrete definition and the measurement. Accordingly, there is a lack of clarification and in-depth discussions of several fundamental aspects or dimensions of measuring energy efficiency, in particular in a political context.

Efficient energy use , sometimes simply called energy efficiency , is the goal to reduce the amount of energy required to provide products and services. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort. Installing light-emitting diode bulbs , fluorescent lighting , or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production process [1] or by application of commonly accepted methods to reduce energy losses.

Revisiting energy efficiency fundamentals

Pillai N. Published in:. Traditionally, there are two basically reciprocal energy efficiency Indicators: one, in terms of energy intensity, that is, energy use per unit of activity output, and the other, in terms of energy productivity, that is, activity output per unit of energy use. The enquiry that has proceeded from the problems associated with this method of a single energy input factor in terms of productivity has led to multi-factor productivity analysis. We have here two approaches: parametric and non-parametric.

DOI: This Methodology Booklet provides a comprehensive review and methodology guiding principles for constructing energy efficiency indicators, with illustrative examples of application to individual countries. It reviews work done by international agencies and national government in constructing meaningful energy efficiency indicators that help policy makers to assess changes in energy efficiency over time.

Energy efficiency is a central target for energy policy and a keystone to mitigate climate change and to achieve a sustainable development. Although great efforts have been carried out during the last four decades to investigate the issue, focusing into measuring energy efficiency, understanding its trends and impacts on energy consumption and to design effective energy efficiency policies, many energy efficiency-related concepts, some methodological problems for the construction of energy efficiency indicators EEI and even some of the energy efficiency potential gains are often ignored or misunderstood, causing no little confusion and controversy not only for laymen but even for specialists. This paper aims to revisit, analyse and discuss some efficiency fundamental topics that could improve understanding and critical judgement of efficiency stakeholders and that could help in avoiding unfounded judgements and misleading statements. Firstly, we address the problem of measuring energy efficiency both in qualitative and quantitative terms.

Там его дожидается лирджет. Прогремел выстрел. Пуля ударила в асфальт в нескольких метрах позади. Беккер оглянулся. Убийца целился, высунувшись из окна.

 - Не волнуйтесь, он ни слова не понимает по-испански. Беккер нахмурился. Он вспомнил кровоподтеки на груди Танкадо. - Искусственное дыхание делали санитары. - Понятия не имею.

Бринкерхофф громко сглотнул. - Так что вы хотите сказать? - спросил. - Джабба хотел сказать, что это, возможно, не шифр-убийца.

Она окунулась в мыльную пену и попыталась забыть о Стоун-Мэнор и Смоки-Маунтинс. Куда его понесло? - думала.  - Почему он не звонит. Вода из горячей постепенно превратилась в теплую и, наконец, холодную. Она уже собиралась вылезать, как вдруг ожил радиотелефон.
