Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the energy security of the United States – its ability to obtain reliable, affordable, and sufficient supplies of energy while meeting the goals of achieving environmental sustainability and protecting national security. The economic and national security of the United States is largely dependent upon fossil fuels, especially oil. Without significant changes to current practices and patterns of energy production and use, the domestic and global impacts – security, economic, and environmental – are expected to become worse over the coming decades. Growing US and global energy demands need to be met and the anticipated impacts of climate change must be avoided – all at an affordable price, while avoiding conflict with other nations that have similar goals. Bernell and Simon examine the current and prospective landscape of American energy policy, from tax incentives and mandates at the federal and state level to promote wind and solar power, to support for fracking in the oil and natural gas industries, to foreign policies designed to ensure that markets and cooperative agreements — not armies, navies and rival governments — control the supply and price of energy resources. They look at the variety of energy related challenges facing the United States and argue that public policies designed to enhance energy security have at the same time produced greater insecurity in terms of fostering rising (and potentially unmet) energy needs, national security threats, economic vulnerability, and environmental dangers.

This book was released on 2017-10-25 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.

Download or read book Smart Energy Strategies written by and published by vdf Hochschulverlag AG. This book was released on 2008 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enormous challenge of creating a longterm sustainable energy system calls for the participation of engineers, natural and social scientists. They can contribute both through their research and by helping to craft strategies that steer the future development of the system. A sustainable energy system cannot be developed by technical fixes alone; action is required on a broad front, including institutional and regulatory changes. There is an abundance of scientific evidence on which to base decisions on how to proceed. Still, research has a crucial role to play as well.Smart Energy Strategies highlights smart solutions: advances in technical and social-science energy research, particularly advances related to new information technology (e.g. control and communication); and experience with targeted applications of information technology in the supply and consumption of energy. The conference has focused on smart strategies taking into account current technical and institutional systems, with their inertia and shortcomings; future energy-related challenges: energy security; the growing energy needs of the disadvantaged; and unintended consequences of energy systems, particularly climate change but also uncontrolled money flows; smart technical, institutional, and regulatory mechanisms for meeting these challenges.

Download or read book Balancing Renewable Electricity written by Bert Droste-Franke and published by Springer Science & Business Media. This book was released on 2012-01-21 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important aim behind the restructuring of Germany’s and Europe’s electricity systems is to reduce the environmental burden, especially with respect to greenhouse gas emissions, of the current systems. Emissions must be brought down to a level that is sustainable in the long run and consistent with greenhouse gas emission reduction goals. Meeting these goals will require a system (as best as current knowledge suggests) that will be able to cope simultaneously with the fundamental demands for economic efficiency, environmental sustainability and supply security. Making use of existing scenarios, this study sketches such a system. It focuses in particular on auxiliary systems such as energy storage methods and network extensions. The study introduces technologies that can balance electricity in energy systems and that can serve as enabling technologies for the integration of large quantities of renewable energies in the power supply system. It begins with a discussion of normative aims for the future electricity system before continuing with a description of current policies and political developments and an overview of relevant existing energy system studies. These sections serve as background for the remainder of the study. They are followed by discussion and analysis of the growing demand for means to balance the fluctuations found in electricity generated in power systems with a high penetration of renewable energies, the potentials of diverse technologies, requirements for electrical networks, economic impacts and important legal issues. Finally, the main challenges to the achievement of developing balancing technologies and processes for renewable electricity-dominant systems are summarised and recommendations made.

Download or read book Meeting the Energy Challenges of the 1990s Experts Define the Key Policy Issues written by and published by . This book was released on 1992 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major issue facing the nation is securing sufficient and reliable future energy supplies to meet the increased U.S. Energy demand projected for the 1990's. Key questions in the energy supply and demand equation include: Does the United States have sufficient fossil fuel supplies-coal, oil, and natural gas-to meet growing demand? Can electric utilities adjust to the numerous changes affecting availability of these fuels amidst increasing demand for new capacity? Will end-use approaches such as energy conservation play a greater role in reducing demand? What steps should the nation take in the event of another major oil disruption? To address these issues, the Balancing Energy Supply and Demand panelists focused on four specific topics: the future role of natural gas, challenges facing the electricity industry in the 1990s, the importance of energy efficiency in reducing energy demand, and the need to analyze carefully the means used to ensure energy security.

Download or read book Energy Security Challenges for the 21st Century written by Gal Luft and published by Bloomsbury Publishing USA. This book was released on 2009-08-10 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of energy on global security and economy is clear and profound, and this is why in recent years energy security has become a source of concern to most countries. However, energy security means different things to different countries based on their geographic location, their endowment of resources their strategic and economic conditions. In this book, Gal Luft and Anne Korin with the help of twenty leading experts provide an overview of the world's energy system and its vulnerabilities that underlay growing concern over energy security. It hosts a debate about the feasibility of resource conflicts and covers issues such as the threat of terrorism to the global energy system, maritime security, the role of multinationals and non-state actors in energy security, the pathways to energy security through diversification of sources and the development of alternative energy sources. It delves into the various approaches selected producers, consumers and transit states have toward energy security and examines the domestic and foreign policy tradeoffs required to ensure safe and affordable energy supply. The explains the various pathways to energy security and the tradeoffs among them and demonstrates how all these factors can be integrated in a larger foreign and domestic policy framework. It also explores the future of nuclear power, the complex relations between energy security and environmental concerns and the role for decentralized energy as a way to enhance energy security.

Download or read book Terrorism and the Electric Power Delivery System written by National Research Council and published by National Academies Press. This book was released on 2012-11-25 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electric power delivery system that carries electricity from large central generators to customers could be severely damaged by a small number of well-informed attackers. The system is inherently vulnerable because transmission lines may span hundreds of miles, and many key facilities are unguarded. This vulnerability is exacerbated by the fact that the power grid, most of which was originally designed to meet the needs of individual vertically integrated utilities, is being used to move power between regions to support the needs of competitive markets for power generation. Primarily because of ambiguities introduced as a result of recent restricting the of the industry and cost pressures from consumers and regulators, investment to strengthen and upgrade the grid has lagged, with the result that many parts of the bulk high-voltage system are heavily stressed. Electric systems are not designed to withstand or quickly recover from damage inflicted simultaneously on multiple components. Such an attack could be carried out by knowledgeable attackers with little risk of detection or interdiction. Further well-planned and coordinated attacks by terrorists could leave the electric power system in a large region of the country at least partially disabled for a very long time. Although there are many examples of terrorist and military attacks on power systems elsewhere in the world, at the time of this study international terrorists have shown limited interest in attacking the U.S. power grid. However, that should not be a basis for complacency. Because all parts of the economy, as well as human health and welfare, depend on electricity, the results could be devastating. Terrorism and the Electric Power Delivery System focuses on measures that could make the power delivery system less vulnerable to attacks, restore power faster after an attack, and make critical services less vulnerable while the delivery of conventional electric power has been disrupted.

Download or read book The Power of Renewables written by Chinese Academy of Engineering and published by National Academies Press. This book was released on 2011-01-29 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States and China are the world's top two energy consumers and, as of 2010, the two largest economies. Consequently, they have a decisive role to play in the world's clean energy future. Both countries are also motivated by related goals, namely diversified energy portfolios, job creation, energy security, and pollution reduction, making renewable energy development an important strategy with wide-ranging implications. Given the size of their energy markets, any substantial progress the two countries make in advancing use of renewable energy will provide global benefits, in terms of enhanced technological understanding, reduced costs through expanded deployment, and reduced greenhouse gas (GHG) emissions relative to conventional generation from fossil fuels. Within this context, the U.S. National Academies, in collaboration with the Chinese Academy of Sciences (CAS) and Chinese Academy of Engineering (CAE), reviewed renewable energy development and deployment in the two countries, to highlight prospects for collaboration across the research to deployment chain and to suggest strategies which would promote more rapid and economical attainment of renewable energy goals. Main findings and concerning renewable resource assessments, technology development, environmental impacts, market infrastructure, among others, are presented. Specific recommendations have been limited to those judged to be most likely to accelerate the pace of deployment, increase cost-competitiveness, or shape the future market for renewable energy. The recommendations presented here are also pragmatic and achievable.

Download or read book Energy Security and Development written by B. Sudhakara Reddy and published by Springer. This book was released on 2015-02-05 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a systematic framework for energy suppliers, policy makers, academics, students, and all others interested in energy security, and analyzes key issues concerning energy, security and sustainability with the help of a wealth of data. While sustainability is the broadest objective, energy security is an important part of it, at the global, national and societal levels. The development of a sustainable, long-term solution to meeting the world’s energy needs is a defining issue of our time, since central global challenges that the world faces—poverty alleviation, climate change, and environmental degradation—are directly linked to energy security. The contributions cover key issues in sustainable energy and illustrate that the insecurity of a majority of countries owes to internal factors which have more to do with market forces, inefficient technologies, lack of institutions, environmental insecurity, pricing mechanisms, etc., and less to do with the international situation. The links between energy and development are both direct and indirect. Directly, energy provides several services and utilities to maintain human well-being, and also does so indirectly through stakeholders. This volume addresses both the direct and indirect links and provides sustainable alternatives, helping readers to better grasp the resilience of both socio-economic and resource sub-systems in the process. The issues affecting energy supply and demand, including technology portfolios, environmental considerations and consumer attitudes are thoroughly discussed. One of the critical questions that arises is how to facilitate energy investment. The investment climate and the key issues involved are analyzed, including: the capital flows with reasonable and stable investment frameworks, timely decision-making by governments, and open markets. The broad objective of the volume is to foster a deeper understanding of the concept of energy security and to identify the methods of analysis, policy initiatives and future research needed to generate a balanced pattern of energy use and mitigate its impact on humanity and the environment.

Download or read book Best Practices and Research for Handling Demand Response Security Issues in the Smart Grid written by Prakarn Asavachivanthornkul and published by . This book was released on 2010 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: When electricity demand is peak, utilities and other electric Independent Systems Operators (ISOs) keep electric generators on-line in order to meet the high demand. In some cases, new power plants have to be built. This solution increases costs, wastes energy and creates air pollution. To overcome this, many utilities, government, and others have been developing Demand Response (DR) programs to manage growth in peak electricity demands, and to provide more reliable and more economic energy. The primary focus of the Demand Response (DR) is to provide two-way communications to customers so that the energy-management and control system (EMCS) at the customer's sites can take action based on the demands for electricity and electricity prices. As a result, when the grid supply becomes strained or when the electricity prices reach a certain point, demand response programs are intended to lower the energy use in return for reducing total system costs and electric loads on the grid. DR systems are expected to be eventually utilized in most of California's residential and commercial energy customers. The breach in security goals' confidentiality, integrity, availability and accountability -- could adversely affect the system and large number of customers. The impacts vary from the reliability of the grid itself to the customers' electric bills and to the privacy loss of the customers. In some cases, it could affect health and safety of customers. This project discusses security risks of DR systems, addresses information security best practices to mitigate those risks and identifies potential Research and Development (R&D) issues existing in DR systems with the hope of increasing awareness of security issues existing in DR systems. The results show that although DR systems have a number of potential security risks and vulnerabilities that must be addressed, information security best practices can be used to mitigate some of them. In some situations (e.g., ensuring non-repudiation), where the best practices could not be directly used, further research will be required to address security issues and appropriate R&D issues are identified for those unique cases as well.

Download or read book Smart and Power Grid Systems Design Challenges and Paradigms written by Kolla Bhanu Prakash and published by CRC Press. This book was released on 2023-03-10 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Smart Grid represents an unprecedented opportunity to move the energy industry into a new era of reliability, availability, and efficiency that will contribute to our economic and environmental health. During the transition period, it will be critical to carry out testing, technology improvements, consumer education, development of standards and regulations, and information sharing between projects to ensure that the benefits we envision from the Smart Grid become a reality. Today, an electricity disruption such as a blackout can have a domino effect—a series of failures that can affect banking, communications, traffic, and security. This is a particular threat in the winter, when homeowners can be left without heat. A smarter grid will add resiliency to our electric power system and make it better prepared to address emergencies such as severe storms, earthquakes, large solar flares, and terrorist attacks. Because of its two-way interactive capacity, the Smart Grid will allow for automatic rerouting when equipment fails or outages occur. This will minimize outages and minimize the effects when they do happen. When a power outage occurs, Smart Grid technologies will detect and isolate the outages, containing them before they become large-scale blackouts. The new technologies will also help ensure that electricity recovery resumes quickly and strategically after an emergency—routing electricity to emergency services first, for example. In addition, the Smart Grid will take greater advantage of customer-owned power generators to produce power when it is not available from utilities. By combining these "distributed generation" resources, a community could keep its health center, police department, traffic lights, phone system, and grocery stores operating during emergencies. In addition, the Smart Grid is a way to address an aging energy infrastructure that needs to be upgraded or replaced. This book shows that Smart Grids can address energy efficiency, to bring increased awareness to consumers about the connection between electricity use and the environment, bring increased national security to our energy system—drawing on greater amounts of home-grown electricity that is more resistant to natural disasters and attack.

This book was released on 2016-09-30 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electricity, supplied reliably and affordably, is foundational to the U.S. economy and is utterly indispensable to modern society. However, emissions resulting from many forms of electricity generation create environmental risks that could have significant negative economic, security, and human health consequences. Large-scale installation of cleaner power generation has been generally hampered because greener technologies are more expensive than the technologies that currently produce most of our power. Rather than trade affordability and reliability for low emissions, is there a way to balance all three? The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies considers how to speed up innovations that would dramatically improve the performance and lower the cost of currently available technologies while also developing new advanced cleaner energy technologies. According to this report, there is an opportunity for the United States to continue to lead in the pursuit of increasingly clean, more efficient electricity through innovation in advanced technologies. The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies makes the case that America's advantagesâ€"world-class universities and national laboratories, a vibrant private sector, and innovative states, cities, and regions that are free to experiment with a variety of public policy approachesâ€"position the United States to create and lead a new clean energy revolution. This study focuses on five paths to accelerate the market adoption of increasing clean energy and efficiency technologies: (1) expanding the portfolio of cleaner energy technology options; (2) leveraging the advantages of energy efficiency; (3) facilitating the development of increasing clean technologies, including renewables, nuclear, and cleaner fossil; (4) improving the existing technologies, systems, and infrastructure; and (5) leveling the playing field for cleaner energy technologies. The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies is a call for leadership to transform the United States energy sector in order to both mitigate the risks of greenhouse gas and other pollutants and to spur future economic growth. This study's focus on science, technology, and economic policy makes it a valuable resource to guide support that produces innovation to meet energy challenges now and for the future.
