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.

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.

Dimensions of energy efficiency in a political context

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. The purpose of this manual is to provide data collectors and users with a full explanation of the methodology and definitions used in the JODI Oil questionnaire. Moreover it was deemed useful to supply some background information on how oil is produced, refined, etc.

The manual also covers data verification methodologies to help professionals completing the JODI-Gas data reporting. Energy efficiency is a growing policy priority for many countries around the world. It is widely recognised as the most cost-effective and readily available means to address numerous energy-related issues, including energy security, the social and economic impacts of high energy prices and concerns about climate change. At the same time, energy efficiency increases competitiveness and promotes consumer welfare.

Yet, choosing and developing appropriate indicators to support the development of policies is not straightforward. Thank you for subscribing.

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

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. Secondly, main methodological problems standing in the way of the construction of EEI are discussed, and a sequence of actions is proposed to tackle them in an ordered fashion. Finally, two key topics are discussed in detail: the links between energy efficiency and energy savings, and the border between energy efficiency improvement and renewable sources promotion.

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

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.

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.

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.

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. Here, we discuss and analyse two aspects of energy efficiency and ways to measure it, namely the formulation of a baseline and the accounting methods, in order to clarify ongoing discussions. Additionally, several baselines can be meaningfully defined and used in a political context.

 Утечка информации. - Никаких изменений. Внезапно Мидж судорожно указала на экран. - Смотрите.

 Сэр, - задыхаясь проговорил Чатрукьян.  - ТРАНСТЕКСТ вышел из строя. - Коммандер, - вмешалась Сьюзан, - я хотела бы поговорить… Стратмор жестом заставил ее замолчать. Глаза его неотрывно смотрели на Чатрукьяна.

 - Добрый вечер, мистер Хейл.

Приступайте. - Мы не успеем! - крикнула Соши.  - На это уйдет полчаса.
