Zustand: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | This book is dedicated to the subject of environmental labels. The basis for the classification of its parts goes back to the types of environmental labelling according to the classification provided by the International Organization for Standardization. The idea of compiling this book came to the author's mind when it was observed that national environmental labelling models had been developed in most countries. This is, however, not the case everywhere; in many other countries, even the initial steps have not been taken.…

Zustand: New. Idioma/Language: Inglés. With shortages of fossil energy and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Currently, a heavy focus is on biofuels made from crops, crop residues and wood. Though it may seem beneficial to use renewable plant materials for biofuel, their use raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources. All renewable energy systems need to be investigated because humankind has limited oil, gas and coal reserves remaining. In addition, coal will become increasingly difficult to extract and will greatly increase the global warming threat. Serious energy conservation and research on viable renewable energy technologies are needed. This book considers the effectiveness and economics of several renewable energy technologies of current interest, including biofuels, solar and wind. *** Nota: Los envíos a España peninsular, Baleares y Canarias se realizan a través de mensajería urgente.

Zustand: Sehr gut. Zustand: Sehr gut | Seiten: 528 | Sprache: Englisch | Produktart: Bücher | The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40¿50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40¿50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.…
