    Energy is an important cost factor in the U.S iron and steel industry. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. iron and steel industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels. A discussion of the structure, production trends, energy consumption, and greenhouse gas emissions of the iron and steel industry is provided along with a description of the major process technologies used within the industry. Next, a wide variety of energy efficiency measures are described. Many measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in the steel and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers in the U.S. iron and steel industry reduce energy consumption and greenhouse gas emissions in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures?and on their applicability to different production practices?is needed to assess their cost effectiveness at individual plants

    Energy [R]evolution 2008--a sustainable world energy perspective

    The Energy [R]evolution 2008 scenario is an update of the Energy [R]evolution scenario published in 2007. It takes up recent trends in global socio-economic developments, and analyses to which extent they affect chances for achieving global climate protection targets. The main target is to reduce global CO2 emissions to 10 Gt per year in 2050, thus limiting global average temperature increase to 2 °C and preventing dangerous anthropogenic interference with the climate system. A review of sector and region specific energy efficiency measures resulted in the specification of a global energy demand scenario incorporating strong energy efficiency measures. The corresponding energy supply scenario has been developed in an iterative process in close cooperation with stakeholders and regional counterparts from academia, NGOs and the renewable energy industry. The Energy [R]evolution scenario shows that renewable energy can provide more than half of the world's energy needs by 2050. Developing countries can virtually stabilise their CO2 emissions, whilst at the same time increasing energy consumption through economic growth. OECD countries will be able to reduce their emissions by up to 80%.Global energy scenario Renewable energies Energy efficiency

    Assessment of bottom-up sectoral and regional mitigation potentials

    The greenhouse gas mitigation potential of different economic sectors in three world regions are estimated using a bottom-up approach. These estimates provide updates of the numbers reported in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4). This study is part of a larger project aimed at comparing greenhouse gas mitigation potentials from bottom-up and top-down approaches. The sectors included in the analysis are energy supply, transport, industry and the residential and service sector. The mitigation potentials range from 11 to 15 GtCO2eq. This is 26-38% of the baseline in 2030 and 47-68% relative to the year 2000. Potential savings are estimated for different cost levels. The total potential at negative costs is estimated at 5-8% relative to the baseline, with the largest share in the residential and service sector and the highest reduction percentage for the transport and industry sectors. These (negative) costs include investment, operation and maintenance and fuel costs and revenues at moderate discount rates of 3-10%. At costs below 100 US$/tCO2, the largest potential reductions in absolute terms are estimated in the energy supply sector, while the transport sector has the lowest reduction potential.Sectoral mitigation costs Climate policy

    energy [r]evolution - A sustainable world energy outlook

    Der Bericht stellt die Neuauflage der Weltenergie-Szenarien dar, die das Institut für Technische Thermodynamik des Deutschen Zentrums für Luft- und Raumfahrt (DLR) zusammen mit über 30 weiteren Experten im Auftrag von Greenpeace International und dem European Renewable Energy Council (EREC) erarbeitet haben. Die Weltenergie-Szenarien „Energy [R]evolution 2010“ zeigen, wie die globalen CO2-Emissionen von heute 30 Milliarden Tonnen pro Jahr bis zur Mitte des Jahrhunderts auf rund zehn Milliarden Tonnen pro Jahr gesenkt werden können. Diese drastische Reduktion der Treibhausgase ist notwendig, um den Anstieg der globalen Durchschnittstemperatur auf zwei Grad Celsius gegenüber dem vorindustriellen Niveau zu beschränken. Gegenüber der letzten Studie geht ein zweites Advanced Energy [R]evolution Szenario noch einen Schritt weiter: Sollte diese CO2-Minderung aufgrund bisher nicht berücksichtigter langfristiger Klimaeffekte die Klimaerwärmung nicht aufhalten, so können zusätzliche Reduktionspotenziale den CO2-Ausstoß schon 10 Jahre früher und bis 2050 sogar bis auf 3,8 Milliarden Tonnen pro Jahr senken. Die Studie, veröffentlicht von Greenpeace International und EREC, beinhaltet u. a. eine umfangreiche Darstellung der Szenarienannahmen sowie der berechneten Kennwerte des Energiesystems je Weltregion

    energy[r]evolution - A sustainable global energy outlook

    A sustainable energy supply can be achieved, even under conditions of global economic growth - this is the outcome of the updated global energy scenario developed on behalf of Greenpeace International and the European Renewable Energy Council (EREC) by the Institute of Technical Thermodynamics (Institut für Technische Thermodynamik) of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in cooperation with over 30 other scientists and institutes. The global energy scenario - the so-called Energy [R]evolution Scenario - shows how global CO2 emissions can be reduced from 30 billion tonnes per year today to about ten billion tonnes per year by 2050. This drastic reduction of greenhouse gas emissions is necessary to ensure that the rise in the global average temperature relative to the pre-industrial level does not exceed two degrees Celsius. The study shows that these goals can in fact be compatible with access to electricity for people around the world, a reliable and affordable supply of energy as well as global economic growth, as long as full use is made of all available options for efficient use of energy and for expansion of renewable energy
