countries through collective response to physical disruptions in oil supply and to advise member countries on sound energy policy. The IEA carries out a comprehensive programme of energy co-operation among 28 advanced economies, each of which is obliged to hold oil stocks equivalent to 90 days of its net imports. The Agency aims to: n Secure member countries ’ access to reliable and ample supplies of all forms of energy; in particular, through maintaining effective emergency response capabilities in case of oil supply disruptions. n Promote sustainable energy policies that spur economic growth and environmental protection in a global context – particularly in terms of reducing greenhouse-gas emissions that contribute to climate change. n Improve transparency of international markets through collection and analysis of energy data. n Support global collaboration on energy technology to secure future energy supplies and mitigate their environmental impact, including through improved energy efficiency and development and deployment of low-carbon technologies. © OECD/IEA, 2010 International Energy Agency 9 rue de la Fédération

Energy Efficiency: Efficiency or Monopsony?

Timothy J. Brennan · RePEc: Research Papers in Economics · 2009

The cliché in the electricity sector, the "cheapest power plant is the one we don’t build, " seems to neglect the benefits of the energy that plant would generate. Those overall benefits could be countered by benefits to consumers if "not building that plant" was the result of monopsony. A regulator acting as a monopsonist may need to avoid rationing demand at monopsony prices. Subsidizing energy efficiency to reduce electricity demand at the margin can solve that problem, if energy efficiency and electricity use are substitutes. We may not observe these effects if the regulator can set price as well as quantity, lacks buyer-side market power, or is legally precluded from denying generators a reasonable return on capital. Nevertheless, the possibility of monopsony remains significant in light of the debate as to whether antitrust enforcement should maximize consumer welfare or total welfare.

Technology efficiency or allocation efficiency

Hailong Cai, Tianyao Yan · RePEc: Research Papers in Economics

Purpose - The emergence of mega-farms in middle-income countries like Brazil and Ukraine and the efforts to consolidate small farms into larger ones in China and elsewhere have suggested that new institutional arrangements and technology progress may increase the significant farm economies of size, and therefore challenging the classical inverse relationship (IR) between productivity and farm size. The purpose of this paper is to conduct a research to examine the existence of IR in China’s cereal production and further explore the possible mechanism. Design/methodology/approach - Based on the panel data concerning farms from 31 provinces in China in 2009–2014, technology efficiency and allocation efficiency in cereal production were measured based on the Translog production function. Findings - In China, an IR exists between wheat, rice and maize production after controlling the related variables. Further, the presence of this IR is due to allocation efficiency rather than technology efficiency. Results of technology efficiency show that there is no significant difference between different size groups; in other words, even the larger size groups enjoy a higher technology efficiency in rice production. Results of allocation efficiency demonstrate that, compared with the larger farms, smaller holders tend to invest more in factors which are beneficial in growing productivity. Hence, yields of small-size farms exceed those of large-size farms, which consequently leads to the IR. Practical implications - The scale consolidation of cropland is harmless to the efficiency of factor utilization and, conversely, may contribute in improving the technology efficiency of specific crops (like rice). Based on the results of allocation efficiency estimation, the extent of misallocation in large scales is relatively less due to their less input of fertilizer and pesticide; thus, the size-improving policy of farmland may contribute to the ease of the non-point pollution in agriculture. Originality/value - The existing discussions of the IR in the context of recent China mainly focus on the accurate verification of IRs. This paper steps forward from the perspective of technology efficiency and allocation efficiency and explores the exact resources of IR with up-to-date and representative data and hopes to find some new conclusions.

Energy-Efficiency versus Carbon-Efficiency

Prashant Shenoy · ACM SIGEnergy Energy Informatics Review · 2022

Improving the energy-efficiency of computing systems has been the focus of computer science research for many decades. In the data center domain, for example, there has been an intense focus on improving energy efficiency by improving the Power Usage Effectiveness (PUE) of data centers. Other domains such as civil and mechanical engineering have also focused on improving the energy efficiency of built environments such as buildings. More recently, there has been an increased emphasis on sustainability on the human-built infrastructure of various kinds motivated by climate change, which has resulted in an emphasis on reducing carbon emissions of such infrastructure by optimizing their carbon efficiency.

Information Efficiency: Streamlining Energy Efficiency

Scott A cGaraghan · 1998

Industry-wide protocols for the measurement ancl verification (M&V) of energy savings have proven critical in the growth of the perliormance contracting market. International M&V protocols provide project financiers and facility owners assurance that energy efficiency project viability is measured consistently and impartially. As the standardization of and resultant reliance upon M&V protocols continues, the itiormation processing requirerm.mts for projects will increase. A similar effort to standardize performance contract project data and develop techniques to efficiently handle energy inilormation (InfoEfficiency) will lead to an even greater acceptance of performance contracting and a subsequent growth in the market. The U.S. Department of Energy, through the Federal Energy Management Program (FEMP), is currently involved in an aggressive effort to increase the use of Energy Savings Performance Contracting by signing six regional contracts for up to $4.5 billion worth of work in federal facilities. As a means to manage this volume, and to lower the cost of implementing projects, FEMP is designing art integrated project itiormation system which allows /ill project participants to quickly and easily evaluate projects, both during the planning stages and while the project is in progress. Several utilities and states are also working on performance contracting programs to supplement traditional DSM programs. Using the success of the industry-consensus M&V protocols as a model, the authors propose using these large programs as the testing ground for an industry-wide effort to raise understanding of information efficiency issues and to develop means for dealing with them.

Capitalist Efficiency and Socialist Efficiency

David Gordon · Monthly Review · 1976

Marxism has been blooming around the world. Paul Sweezy and Harry Magdoff call it "a veritable renaissance." Samir Amin celebrates an "extraordinary rebirth." Just as socialist practice has deepened and spread its roots internationally, so has Marxian theory borne increasingly rich and bounteous fruit.… The Marxian renaissance has involved some theoretical tussles with the earlier Marxist orthodoxy. These theoretical reformulations have necessarily focused on the central problematic of the materialist perspective…. With <em>Labor and Monopoly Capital</em>, Harry Braverman has provided some central elements lor this clarified focus, helping arm us with many critical arguments for our assault on traditional views.<p class="mrlink"><p class="mrpurchaselink"><a href="http://monthlyreview.org/index/volume-28-number-3" title="Vol. 28, No. 3: July-August 1976" target="_self">Click here to purchase a PDF version of this article at the <em>Monthly Review</em> website.</a></p>

Efficiency

Hwang-Sun Kang · 2007

This article introduces the concept of efficiency and discusses the validity of the concept being used as the primary criterion of performance measurement in the public sector. From Wilson, the father of public administration in 1887 to Osborne and Gaebler, advocates of reinventing government in 1992, efficiency has been said to be the first ideology of public administration. Wilson pinpointed the role of government: government should be able to implement delegated tasks from the legislature.

Efficiency

DigitalCommons - Kennesaw State University (Kennesaw State University) · 2017

The previous two activities in this module have shown us the importance of conservation laws. These laws provide extra “tools” that allow us to analyze certain aspects of physical systems and to be able to predict the motion of objects in the systems without using more complicated analysis. Even in situations wherein we cannot exactly solve the motion, these laws are incredibly useful. For instance, if someone shows us an incredibly complicated device that can seemingly produce electricity with no energy input whatsoever, we know not to invest money in this device, as it must be a sham since it violates the conservation of energy principle. However, both of these conservation laws are theoretical constructs that rarely, if ever, hold 100% true in the real world. The experiments that were run showed proof of this, as the experimental results did not match the theoretical model. Energy is lost as it is transferred from kinetic to potential, and vice-versa. Momentum was not conserved during the collisions, as they turned out to be neither perfectly elastic or perfectly inelastic. It turns out that there is another law at work that limits these other conservation laws: the Second Law of Thermodynamics.
