Energy is central to sustainable development. It has huge environmental, social, and economic impacts, such as its influence on climate change, poverty reduction efforts, industrial and agricultural productivity and environmental and human health. The development of strategies towards a sustainable energy transition is one of the most important world challenges of the twenty-first century. The choices that we will make in the coming years about energy will determine what world future generations will inherit. This book gives an overview of the key issues, strategies, operational guidelines and policy implications of current research on the transition to more sustainable energy consumption. I...
As the residential buildings sector accounts for around 30 percent of the final energy demand in Germany, this sector is increasingly becoming the focus of public attention with regard to climate change. In this book, decisions on energy consumption by private households are examined. The analyses are based on several empirical methods. The results show that the road to more sustainable energy consumption in residential buildings is not hampered by a lack of will on behalf of the consumers. However one should be realistic that there are many instances where improving thermal institution involves additional economic costs for individual households.
Çukurova University, Turkey in collaboration with Ljubljana University, Slovenia and the International Energy Agency Implementing Agreement on Energy Conservation Through Energy Storage (IEA ECES IA) organized a NATO Advanced Study Institute on Thermal Energy Storage for Sustainable Energy Consumption – Fundamentals, Case Studies and Design (NATO ASI TESSEC), in Cesme, Izmir, Turkey in June, 2005. This book contains manuscripts based on the lectures included in the scientific programme of the NATO ASI TESSEC.
Quantities of all forms of energy consumed for collection and treatment of municipal wastewater are estimated. Heat energy is equated to electrical energy by a conversion factor of 10,500 Btu/kwh. Total energy consumption, expressed as kwh/mg of wastewater treated, ranges from 2300-3700 kwh/mg. Energy used for construction of the treatment plant and the sewerage system represents 35-55% of the total energy consumed. The remainder used for plant operation is predominately (65-75%) electrical energy. The use of high efficiency aeration devices combined with good maintenance practices appears to offer the best opportunity for conservation of energy within the plant. Recovery of energy from the sludge produced at the plant can be accomplished by anaerobically digesting the sludge and using the digester gas as fuel for internal combustion engines. In large plants, when the sludge is sufficiently dewatered, it is also possible to recover energy by incinerating the dewatered sludge with production of steam in a waste heat boiler. The steam can then be used within the plant or expanded through a steam turbine to produce mechanical or electrical energy.
The fIrst oil crisis of 1973-74 and the questions it raised in the economic and social fIelds drew attention to energy issues. Industrial societies, accustomed for two decades or more to energy sufficiently easy to produce and cheap to consume that it was thought to be inexhaustible, began to question their energy future. The studies undertaken at that time, and since, on a national, regional, or world level were over-optimistic. The problem seemed simple enough to solve. On the one hand, a certain number of resources: coal, the abundance of which was discovered, or rather rediscovered oil, source of all the problems ... In fact, the problems seemed to come, if not from oil itself (an easy e...
Originally published in 1978, this report summarises the results of a workshop on why energy consumption is much higher in the United States than other industrialised countries with similar living standards. The papers included in the workshop make interesting comparisons between countries such as Japan and the United Kingdom and the United States, raising interesting questions about environmental policy-making. This title will be of interest to students of Environmental Studies.
The book contains the data required to measure and manage energy consumption in residential buildings. This book describes energy information in detail so that any homeowner can measure energy use on a continuing basis, make decisions regarding how to conserve energy, implement improvements, then monitor the results of those improvements. In the past, it has been difficult to collect residential energy consumption data in real-time. This book helps overcome that challenge by teaching readers how to use self-installed data collection devices that monitor consumption of circuits or appliances, along with freely available information to benchmark against other homes in the area. It demonstrates...
