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.
"This study is a joint effort by WHO, aimed at improving quality, safety and accessibility of health services in support of universal health coverage, and The World Bank in furtherance of the Energy Sector Management Assistance Program (ESMAP)-funded activity on Defining and Measuring Access to Energy for Socio-Economic Development. The WHO inputs are drawn from two years of comprehensive review of energy use in the health sector as part of the Health in the Green Economy series, for which the preliminary findings were published in 2011 and the full report is to be published in 2015. The study also draws upon the framework for measuring energy access developed by the World Bank in consultation with partner agencies to track progress under the Sustainable Energy for All (SE4All) initiative."--Publisher's description.

This open access book addresses the issue of diffusing sustainable energy access in low- and middle-income contexts. Access to energy is one of the greatest challenges for many people living in low- income and developing contexts, as around 1.4 billion people lack access to electricity. Distributed Renewable Energy systems (DRE) are considered a promising approach to address this challenge and provide energy access to all. However, even if promising, the implementation of DRE systems is not always straightforward. The book analyses, discusses and classifies the promising Sustainable Product-Service System (S.PSS) business models to deliver Distributed Renewable Energy systems in an effective, efficient and sustainable way. Its message is supported with cases studies and examples, discussing the economic, environmental and socioethical benefits as well as its limitations and barriers to its implementation. An innovative design approach is proposed and a set of design tools are supplied, enabling readers to create and develop Sustainable Product-Service System (S.PSS) solutions to deliver Distributed Renewable Energy systems. Practical applications of the book’s design approach and tools by companies and practitioners are discussed and the book will be of interest to readers in design, industry, governmental institutions, NGOs as well as researchers.
Imagine fuel without fear. No climate change. No oil spills, no dead coalminers, no dirty air, no devastated lands, no lost wildlife. No energy poverty. No oil-fed wars, tyrannies, or terrorists. No leaking nuclear wastes or spreading nuclear weapons. Nothing to run out. Nothing to cut off. Nothing to worry about. Just energy abundance, benign and affordable, for all, forever. That richer, fairer, cooler, safer world is possible, practical, even profitable-because saving and replacing fossil fuels now works better and costs no more than buying and burning them. Reinventing Fire shows how business-motivated by profit, supported by civil society, sped by smart policy-can get the US completely off oil and coal by 2050, and later beyond natural gas as well. Authored by a world leader on energy and innovation, the book maps a robust path for integrating real, here-and-now, comprehensive energy solutions in four industries-transportation, buildings, electricity, and manufacturing-melding radically efficient energy use with reliable, secure, renewable energy supplies.Popular in tone and rooted in applied hope, Reinventing Fire shows how smart businesses are creating a potent, global, market-driven, and explosively growing movement to defossilize fuels. It points readers to trillions in savings over the next 40 years, and trillions more in new business opportunities.Whether you care most about national security, or jobs and competitive advantage, or climate and environment, this major contribution by world leaders in energy innovation offers startling innovations will support your values, inspire your support, and transform your sense of possibility.Pragmatic citizens today are more interested in outcomes than motives. Reinventing Fire answers this trans-ideological call. Whether you care most about national security, or jobs and competitive advantage, or climate and environment, its startling innovations will support your values, inspire your support, and transform your sense of possibility.
The Tcl language and Tk graphical toolkit are simple and powerful building blocks for custom applications. The Tcl/Tk combination is increasingly popular because it lets you produce sophisticated graphical interfaces with a few easy commands, develop and change scripts quickly, and conveniently tie together existing utilities or programming libraries.One of the attractive features of Tcl/Tk is the wide variety of commands, many offering a wealth of options. Most of the things you'd like to do have been anticipated by the language's creator, John Ousterhout, or one of the developers of Tcl/Tk's many powerful extensions. Thus, you'll find that a command or option probably exists to provide just what you need.And that's why it's valuable to have a quick reference that briefly describes every command and option in the core Tcl/Tk distribution as well as the most popular extensions. Keep this book on your desk as you write scripts, and you'll be able to find almost instantly the particular option you need.Most chapters consist of alphabetical listings. Since Tk and mega-widget packages break down commands by widget, the chapters on these topics are organized by widget along with a section of core commands where appropriate. Contents include: Core Tcl and Tk commands and Tk widgets C interface (prototypes) Expect [incr Tcl] and [incr Tk] Tix TclX BLT Oratcl, SybTcl, and Tclodbc
Now featuring a new preface by Peter Thiel Two renowned investment advisors and authors of the bestseller The Great Reckoning bring to light both currents of disaster and the potential for prosperity and renewal in the face of radical changes in human history as we move into the next century. The Sovereign Individual details strategies necessary for adapting financially to the next phase of Western civilization. Few observers of the late twentieth century have their fingers so presciently on the pulse of the global political and economic realignment ushering in the new millennium as do James Dale Davidson and Lord William Rees-Mogg. Their bold prediction of disaster on Wall Street in Blood in the Streets was borne out by Black Tuesday. In their ensuing bestseller, The Great Reckoning, published just weeks before the coup attempt against Gorbachev, they analyzed the pending collapse of the Soviet Union and foretold the civil war in Yugoslavia and other events that have proved to be among the most searing developments of the past few years. In The Sovereign Individual, Davidson and Rees-Mogg explore the greatest economic and political transition in centuries—the shift from an industrial to an information-based society. This transition, which they have termed "the fourth stage of human society," will liberate individuals as never before, irrevocably altering the power of government. This outstanding book will replace false hopes and fictions with new understanding and clarified values.
