Energie-Effizienz-Indikatoren sind Kennziffern zur Beschreibung der energiewirtschaftlichen Entwicklung. Durch die Verknupfung energiestatistischer Daten mit oekonomischen oder physikalischen Bezugsgroessen koennen sie dazu beitragen, die Entwicklung des Energieverbrauchs zu erklaren und international zu vergleichen. Von besonderem Interesse ist dabei die Frage, in welchem Masse die Verbrauchsentwicklung auf wirtschaftliches Wachstum, auf Strukturwandel und auf Verbesserungen der Energieeffizienz zuruckzufuhren ist. Im Auftrag des Bundesministeriums fur Wirtschaft und Technologie ist untersucht worden, welche Rolle solche Indikatoren im Rahmen einer marktwirtschaftlich orientierten Energiepolitik grundsatzlich spielen koennen und wie deren Aussagefahigkeit hinsichtlich statistischer Methoden und Daten zu beurteilen ist. Anhand ausgewahlter Indikatoren fur einzelne Sektoren wird die Entwicklung des Energieverbrauchs in Deutschland differenziert analysiert.

Fundamentals of Renewable Energy Processes, Fourth Edition, winner of a 2022 Textbook Excellence Award (Texty) from the Textbook and Academic Authors Association, provides accessible coverage of clean, safe alternative energy sources such as solar and wind power. Aldo da Rosa's classic and comprehensive resource has provided thousands of engineers, scientists, students and professionals alike with a thorough grounding in the scientific principles underlying the complex world of renewable energy technologies. The fourth edition has been fully updated and revised by new author Juan Ordonez, Director of the Energy and Sustainability Center at Florida State University, and includes new worked examples, more exercises, and more illustrations to help facilitate student learning.

Exponential growth of the worldwide population requires increasing amounts of water, food, and energy. However, as the quantity of available fresh water and energy sources directly affecting cost of food production and transportation diminishes, technological solutions are necessary to secure sustainable supplies. In direct response to this reality, this book focuses on the water-energy-food nexus and describes in depth the challenges and processes involved in efficient water and energy production and management, wastewater treatment, and impact upon food and essential commodities. The book is organized into 4 sections on water, food, energy, and the future of sustainability, highlighting the interplay among these topics. The first section emphasizes water desalination, water management, and wastewater treatment. The second section discusses cereal processing, sustainable food security, bioenergy in food production, water and energy consumption in food processing, and mathematical modeling for food undergoing phase changes. The third section discusses fossil fuels, biofuels, synthetic fuels, renewable energy, and carbon capture. Finally, the book concludes with a discussion of the future of sustainability, including coverage of the role of molecular thermodynamics in developing processes and products, green engineering in process systems, petrochemical water splitting, petrochemical approaches to solar hydrogen generation, design and operation strategy of energy-efficient processes, and the sustainability of process, supply chain, and enterprise.

How the use of nonpolluting, zero-emission hydrogen as fuel could be the cornerstone of a new energy economy. Hydrogen is the most abundant element in the universe. An invisible, tasteless, colorless gas, it can be converted to nonpolluting, zero-emission, renewable energy. When burned in an internal combustion engine, hydrogen produces mostly harmless water vapor. It performs even better in fuel cells, which can be 2.5 times as efficient as internal-combustion engines. Zero-emission hydrogen does not contribute to CO2-caused global warming. Abundant and renewable, it is unlikely to be subject to geopolitical pressures or scarcity concerns. In this new edition of his pioneering book Tomorrow's Energy, Peter Hoffmann makes the case for hydrogen as the cornerstone of a new energy economy. Hoffmann covers the major aspects of hydrogen production, storage, transportation, fuel use, and safety. He explains that hydrogen is not an energy source but a carrier, like electricity, and introduces the concept of "hydricity," the essential interchangeability of electricity and hydrogen. He brings the hydrogen story up to date, reporting on the latest developments, including new hydrogen and fuel-cell cars from GM, Daimler, BMW, Honda, and Toyota. He describes recent political controversies, including Obama administration Energy Secretary (and Nobel laureate in Physics) Steven Chu's inexplicable dismissal of hydrogen-which puts him at odds with major automakers, German Chancellor Angela Merkel, and others. Our current energy system is a complex infrastructure, and phasing in hydrogen will take effort and money. But if we consider the real costs of fossil fuels-pollution and its effects, international tensions over gas and oil supplies, and climate change-we would be wise to promote its development.

Access to oil and natural gas, and their prices, are hugely important axes of geo-political strategy and global economic prospects and have been for a century. This book, written by a Financial Times journalist who has long covered the energy sector, provides readers with the essential information they need for understanding the shifting structure of the global oil and gas economy: where the reserves lie, who produces what, trade patterns, consumption trends, prices. The book highlights political and social issues in the global energy sector -- the domestic inequality, civil conflict and widespread poverty that dependence on oil exports inflicts on developing countries and the strategies of wealthy countries (especially the United States) to control oil-rich regions. Energy demand is on a strong upward trend. The reality of the environmental damage caused by fossil fuels cannot be doubted. What are likely to be the human consequences: changing disease vectors, unprecedented flooding, mass migration? And what is to be done both in the wealthy countries where consumerism drives increasing growth in demand and in developing countries aiming to grow their economies faster? Are alternative energy sources a panacea? Or will the much vaunted hydrogen economy still be based on oil, natural gas and coal? Here is a book that addresses what is perhaps the most pervasive and destabilizing of the issues facing humanity.

In the global North the commoditization of creativity and knowledge under the banner of a creative economy is being posed as the post-industrial answer to dependency on labour and natural resources. Not only does it promise a more stable and sustainable future, but an economy focused on intellectual property is more environmentally friendly, so it is suggested. Contested Powers argues that the fixes being offered by this model are bluffs; development as witnessed in Latin American energy politics and governance remains hindered by a global division of labour and nature that puts the capacity for technological advancement in private hands. The authors call for a multi-layered understanding of sovereignty, arguing that it holds the key to undermining rigid accounts of the relationship between carbon and democracy, energy and development, and energy and political expression. Furthermore, a critical focus on energy politics is crucial to wider debates on development and sustainability. Contested Powers is essential reading for those wondering how energy resources are converted into political power and why we still value the energy we take from our surroundings more than the means of its extraction.
