This book investigates the role of gas networks in future low-carbon energy systems, and discusses various decarbonisation pathways, providing insights for gas network operators, developers, and policy makers. As more countries around the world move towards low-carbon energy systems and increase their exploitation of renewable energy sources, the use of natural gas and the associated infrastructure is expected to undergo a substantial transformation. As such there is a great uncertainty regarding the future role of gas networks and how they will be operated in coming years. The topics addressed include: Fundamentals of gas network operation The impact of variable renewable electricity generation on the operation and expansion of gas networks The impact of decarbonising heat supplies on gas networks Opportunities and challenges of utilising gas networks to transport alternative low-carbon gases such as bio-methane and hydrogen

The use of combined heat and power (CHP) plants and renewable energy sources reduces the amount of greenhouse gases released into the atmosphere and helps to alleviate the consequent climate change. The policies of many governments suggest that the proportion of electrical energy produced by these sources will increase dramatically over the next two decades. Unlike traditional generating units, these new types of power plant are usually 'embedded' in the distribution system or 'dispersed' around the network. As a result, conventional design and operating practices are no longer applicable; for example, power protection principles have to be revised and complex economic questions need to be resolved. This book, intended for both students and practising engineers, addresses all the issues pertinent to the implementation of embedded generation. Much of the material was originally developed for the UMIST MSc/CPD course in Electrical Power Engineering so there is a strong tutorial element. However, since this subject is evolving very rapidly, the authors also discuss the technical and commercial consequences of the very high penetration of embedded generation that are to be expected in the years ahead.

Modern societies require energy systems to provide energy for cooking, heating, transport, and materials processing, as well as for electricity generation. Energy systems include the primary fuel, its conversion, and transport to the point of use. In many cases this primary fuel is still a fossil fuel, a one-use resource derived from a finite supply within our planet, causing considerable damage to the environment. After 300 years of increasing reliance on fossil fuels, particularly coal, it is becoming ever clearer that the present energy systems need to change. In this Very Short Introduction Nick Jenkins explores our historic investment in the exploitation of fossil energy resources and their current importance, and discusses the implications of our increasing rate of energy use. He considers the widespread acceptance by scientists and policy makers that our energy systems must reduce emissions of CO2 and other greenhouse gases, and looks forward to the radical changes in fuel technology that will be necessary to continue to provide energy supplies in a sustainable manner, and extend access across the developing world. Considering the impact of changing to an environmentally benign and low-carbon energy system, Jenkins also looks at future low-carbon energy systems which would use electricity from a variety of renewable energy sources, as well as the role of nuclear power in our energy use. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Throughout the world there is concern over the impact of energy use on the environment (particularly CO2 emissions) and also over the security of fossil fuel supplies. Consequently, governments and energy planners are actively encouraging alternative and cleaner forms of energy production such as renewables (e.g. wind, solar, biomass) and combined heat and power (CHP). The economics and locations of sustainable energy sources have meant that many of these new generators are connected into distribution networks. It is recognized that the information flow and control of distribution networks is inadequate for these future low-carbon electricity supply systems. The future distribution network will change its operation from passive to active, and the distributed generators will be controlled to support the operation of the power system. In many countries this transformation of electricity supply is managed through energy markets and privately owned, regulated transmission and distribution systems. This book discusses the connection of generation to distribution networks and then moves on to consider how sustainable generation can be fully integrated into the operation of the power system. Both technical and economic aspects are addressed. It is written for later-year undergraduate and postgraduate students studying courses on energy. The book has four tutorial chapters (with examples and questions) to provide fundamental material for those without a strong electrical engineering background.

The rapid growth of wind generation has many implications for power system planning, operation and control. This would have been a considerable challenge for the old nationalised power companies; it has become an even greater challenge in today's liberalised electricity markets. Network development, voltage rise, protection, monitoring and control are connection problems common to all wind power generation. These issues are addressed through an understanding of the basic electrical engineering concepts and wind power technology. When wind power approaches 10 percent of all generation, it impinges on system operation. The underlying principles of system balancing are presented, before considering the impact of many variable generation sources whose outputs are difficult to predict. Wind power forecasting is crucial to successful wind power integration, and basic theory and current practice are considered. Storage can also help but it needs to be low cost and, ideally, based on intelligent use of existing load. Finally, electricity markets are explained and the commercial challenges facing wind power are assessed. The book provides a wide-ranging discussion on all major aspects of wind power integration into electricity supply systems. It requires no specialist knowledge and will appeal to engineers from various disciplines looking for an overview of a technology that is providing a major impetus for sustainable electricity supply in the twenty-first century.

Is there only one possible outcome for the evolution of mankind? When two cultures light years apart follow different evolutionary paths, that question could be answered. And many more could be raised. In the twenty-second century, Earth was dying. World population was more than twenty billion, the global environment was in ruins, and living conditions were intolerable everywhere on the planet. Many people thought the only hope for mankind lay in colonizing space. And so giant ships were built to carry brave volunteers who would settle the planets of nearby stars. Many years later, the colonists returned. The Earth they found was a far different place than the Earth of their distant ancestors. And they were not welcome.
