The agri-food chain consumes about one third of the world’s energy production with about 12% of it for crop production and nearly 80% for processing, distribution, retail, preparation and cooking. The agri-food chain also accounts for 80-90% of total global freshwater use where 70% alone is for irrigation. Additionally, on a global scale, freshwater production consumes nearly 15% of the entire energy production. It can therefore be argued that making agriculture and the agri-food supply chain independent from fossil fuel use has a huge potential to contribute to global food security and climate protection not only for the next decades but also for the coming century. Provision of secure, accessible and environmentally sustainable supplies of water, energy and food must thus be a priority. One of the major objectives of the world’s scientists, farmers, decisions makers and industrialists is to overcome the present dependence on fossil fuels in the agro-food sector. This dependency increases the volatility of food prices and affects economic access to sustenance. This book provides a critical review of recent developments in solar, wind and geothermal energy applications in agriculture and the agro-food sector such as processing, distribution, retail, preparation and cooking.

A long established reference book: radical revision for the fifteenth edition includes complete rearrangement to take in chapters on new topics and regroup the subjects covered for easy access to information. The Electrical Engineer's Reference Book, first published in 1945, maintains its original aims: to reflect the state of the art in electrical science and technology and cater for the needs of practising engineers. Most chapters have been revised and many augmented so as to deal properly with both fundamental developments and new technology and applications that have come to the fore since the fourteenth edition was published (1985). Topics covered by new chapters or radically updated sections include: * digital and programmable electronic systems * reliability analysis * EMC * power electronics * fundamental properties of materials * optical fibres * maintenance in power systems * electroheat and welding * agriculture and horticulture * aeronautic transportation * health and safety * procurement and purchasing * engineering economics

Dielectric Properties of Agricultural Materials and Their Applications provides an understanding of the fundamental principles governing dielectric properties of materials, describes methods for measuring such properties, and discusses many applications explored for solving industry problems. The information in this reference stimulates new research for solving problems associated with production, handling, and processing of agricultural and food products. Anyone seeking a better understanding of dielectric properties of materials and application of radio-frequency and microwave electromagnetic energy for solution of problems in agriculture and related fields will find this an essential resource. Presents applications of dielectric properties for sensing moisture in grain and seed and the use of such properties in radio-frequency and microwave dielectric heating of agricultural materials Offers information for finding correlations between dielectric properties and quality attributes such as sweetness in melons, or other desired characteristics of agricultural products Identifies conditions for selective dielectric heating of materials such as insects in grain or biological organisms in soils Provides a solid understanding of dielectric properties and the variables that influence these properties

Agriculture and Energy consists of the proceedings of a conference held at Washington University, St. Louis, Missouri, on June 17-19, 1976. The conference aims to bring together a broad spectrum of researchers concerned with obtaining a better understanding of the energy consumption by agriculture. These researchers are also concerned with developing ways to help food production adapt to occurring and anticipated resource availability problems. This book is organized into nine parts, separating the papers of the conference as chapters. It describes the quantity of energy consumed in particular production processes or in production at various levels of aggregation in the field of agriculture. It also dwells into the economic impacts of energy problems on agricultural production. It looks into the comparative economic and energy costs of the various methods for producing a specific product. Furthermore, this reference material discusses unconventional production methods that can reduce the need for fossil energy inputs by using renewable energy sources or recycling materials. Lastly, the implications of the energy situation for agricultural policy, both in the U.S. and in developing countries, are shown.
