In this title, originally published in 1981, author Robert P. Taylor calls for a greater understanding of rural energy supply and consumption patterns in the developing countries. Here, Taylor specifically examines the rural energy development in China as it is the world’s largest developing country in terms of population, and it has encountered many of the rural energy problems common in other developing countries. This study provides an analysis of China’s rural energy economy from before 1949 to a general discussion of achievements in rural energy development and the rural energy economy in 1981. This is an ideal title for students interested in environmental studies and development studies.

tions is not possible without first putting the problem into a wider con text. Consequently, before proceeding with detailed critical topical cov erage of individual biomass energy sources, uses, and effects, I will extend this preface with a few pages of rather personal reflections (I will use the same device in closing the book: after providing concise topical summaries in Chapter 8, I will conclude with some essayistic musings on renewable energetics, plants, people, and a scientist's responsibility). Interest in biomass energies is just a part of a broader global trend toward renewable energetics, a trend which has evolved speedily after the crude oil price escalation started in 1973. Yet one must be reminded that for the rich countries fossil fuels are, and for a long period shall remain, the foundation of an affluent civilization, while throughout the poor world the reliance of most people on biomass energies for everyday subsistence has brought many damaging environmental and social ef fects; that the reality of sharp price rises for crude oil (actually not so sharp once adjusted for inflation) should not be misconstrued as an "energy crisis"; that the rise of renew abies and the claims made on their behalf by countless enthusiasts look so much better on paper than in reality; and that the potential of biomass energies, an essential ingre dient of renewable scenarios, has been judged more with proselytizing zeal than with critical detachment.

With the death of Mao Tse-tung and the subsequent purge of the "Gang of Four," China's new pragmatic leaders have embarked on a crash program of national development known as the Four Modernizations, This program is geared to the primary objective of turning China into a major world economic and military power by the year 2000. In this book, the outgrowth of a major international conference on China's post-Maoist development, ten distinguished analysts examine one of the core issues in China's current modernization drive: the acquisition and use of modern industrial science and technology. The authors address the politics of China's technological modernization, the institutional structure of technological research, the purchase of foreign technology, constraints on technological absorption, the growth potential of China's critical energy sector, and the modernization of China's military establishment. Supplemented with brief commentaries by leading academic, government, and private sector contributors, their chapters provide an in-depth look at the process, problems, and prospects of China's widely heralded technological revolution.
