Faye Duchin, Glenn-Marie Lange - The Future of the Environment: Ecological Economics and Technological Change

Faye Duchin, Glenn-Marie Lange - The Future of the Environment: Ecological Economics and Technological Change
Publisher: Oxford University Press, USA | 1995-01-26 | ISBN: 0195085744 | PDF | 240 pages | 12.59 MB

One of the most important and complex problems facing both developing and industrialized nations is how to sustain economic growth without harming the environment. Faye Duchin and Glenn-Marie Lange address this issue in a practical and realistic way: through a detailed evaluation of the well-known approach to sustainable development outlined in the Brundtland Report, Our Common Future.
Taking issue with the Brundtland Report's optimistic and widely accepted assumptions, the authors show that the positive effects of recycling, increased fuel-efficiency, and other technological adjustments will not go far enough to provide for truly sustainable development in the long term. Through a new, broad-based empirical analysis, they argue that unless there are significant changes in lifestyles and the use of technologies, continued environmental degradation cannot be avoided. They warn that the trend of making only slight adjustments in the use of technologies, while feasible from an economic point of view for industrialized nations, will undoubtedly lead to further environmental damage.
In addition to offering a clear and unflinching look at what development is really doing to the global environment, the unique conceptual framework developed for this analysis provides an invaluable basis for analysis for the new, multidisciplinary field of ecological economics. Duchin and Lange describe how this new methodology will enable economists and policy-makers to evaluate our options for the future, and choose those that most effectively reduce environmental degradation and achieve sustainable development. The book will appeal to economists, environmental scientists and activists, policy analysts, and ecologists, as well as the general reader with an interest in the sustainable development of our environment.

Evolution of Phase Transitions: A Continuum Theory

Rohan Abeyaratne, "Evolution of Phase Transitions: A Continuum Theory"
Publisher: Cambridge University Press | 2006 | ISBN 0521661471 | PDF | 258 pages | 3.5 MB

This work began with the author's exploration of the applicability of the finite deformation theory of elasticity when various standard assumptions such as convexity of various energies or ellipticity of the field equations of equilibrium are relinquished. The finite deformation theory of elasticity turns out to be a natural vehicle for the study of phase transitions in solids where thermal effects can be neglected. This is an essential work to those interested in the development and application of continuum-mechanical models that describe the macroscopic response of materials capable of undergoing stress- or temperature-induced transitions between two solid phases. The focus is on the evolution of phase transitions which may be either dynamic or quasi-static, controlled by a kinetic relation which in the framework of classical thermomechanics represents information that is supplementary to the usual balance principles and constitutive laws of conventional theory. The book should be of interest to mechanicians, materials scientists, geophysicists, and applied mathematicians.

From Edison to Enron: The Business of Power and What It Means for the Future of Electricity

Richard Munson, "From Edison to Enron: The Business of Power and What It Means for the Future of Electricity"
Publisher: Praeger | 2005 | ISBN 027598740X | PDF | 216 pages | 16.6 MB

The blackout of 2003 illuminated just how dependent America is on electricity. It was not just that some 50 million people in eight states and Ontario were cut off from their televisions, microwaves, ATMs, and email. Without the electrical juice to keep their sockets alive, factory managers were forced to close production lines, city managers shut down water deliveries, grocery store clerks watched their frozen inventory slowly melt away. Economists estimated that the blackout cost Americans $5 billion even as energy analysts were predicting that a similar blackout could happen again. The catastrophe forced us to marvel at the unusual ability of sub-microscopic particles to move like waves inside a wire and cause bulbs to glow. It highlighted the complex requirements for managing the massive generators, transformers, transmission lines, and switch boxes needed to tap and deliver flowing electrons. It encouraged us to recognize the profound impact of electricity on all aspects of commerce and culture. Such events as the blackout, the Enron debacle, and the California "brownouts" also reveal the cracks in a 100-year-old industry structure that have been building ever since Thomas Edison, George Westinghouse, and their contemporaries first managed to harness electricity and make it available to the masses, and tycoons, such as Sam Insull and George Norris, began to concentrate financial control and political influence. From Edison to Enron traces the controversial history of this $210 billion industry--the nation's largest--showcasing the key individuals, technological innovations, corporate machinations, and political battles that have been waged over its domination. Munson maintains that today's technological and regulatory infrastructure, as a function of its history, is a relic that has long outlived its usefulness; he points out that two-thirds of the fuel burned to generate electricity is lost, that Americans pay roughly $100 billion too much each year for heat and power, and that environmentally unfriendly generators are the nation's largest polluters. Meanwhile, innovations in technology and business models are being blocked by entrenched monopolies. Ultimately, Munson argues that current policies and practices, including those favored by the Bush Administration, are preventing entrepreneurs from producing more efficient, healthy, and sustainable power supplies. Moreover, he presents an agenda for business and policy reforms that will stimulate economic development in the United States and around the world.
