The use of the wind as an energy source is increasing and growing worldwide. Wind energy is an important non-fossil option to supplement fossil (coal, natural gas and oil) and nuclear fuels for the generation of electricity.Many parts of the world, particularly the coastlines of Western Europe, North Africa, North and South America, India, Eastern Russia, China, the Philippines, Australia and New Zealand, experience a high annual incidence of wind energy. The United Kingdom of Great Britain and Northern Ireland, together with the Republic of Ireland form a particularly windy location, being favoured with strong westerly winds. The technology of the design and installation of wind turbines and wind farms are, in fact, well established. Operational practice, though, is still being developed as engineers learn by experience.This book is written for electrical engineers concerned with the use of wind power for generating electricity. It incorporates some meteorological features of international wind supply plus a survey of the past and present wind turbines with technical assessment of the choice of turbine sites. Detailed coverage is given to the different types of electrical generator machines used and the electronic control devices employed in modern turbine systems.Importantly, this book devotes full chapters to the integration of wind farms into established electrical grid supply systems, and the environmental and economic aspects of wind generation. Engineers will be drawn to the practical approach in this book, featuring worked numerical examples - complete with answers - at the end of some chapters.

By the end of the 21st century, our oil and natural gas supplies will be virtually nonexistent, and limited coal supplies will be restricted to only a handful of countries. The authors - an environmental scientist and veteran journalist - make abundantly clear that we must plan for a future without reliance on oil. They make a compelling case that the key determinant of our global economy is not so much the invisible hand of the marketplace but the inexorable laws of ecology. Although the coming decades will be a time of much disruption and change of lifestyle, in the end we may learn a wiser, more sustainable stewardship of our natural resources.
This timely, sobering, yet constructive discussion of energy and ecology offers a realistic vision of the near future and many important lessons about the limits of our resources.

Climate change, environmental impact and declining natural resources are driving scientific research and novel technical solutions. Green Energy and Technology serves as a publishing platform for scientific and technological approaches to "green" - i.e., environmentally friendly and sustainable - technologies. While the main focus lies on energy and power supply, the series also covers green solutions in industrial engineering and engineering design. Green Energy and Technology is a monograph series addressing researchers, advanced students and technical consultants, as well as decision makers in industry and politics. The level presentation ranges from instructional to highly technical. Fossil fuels are widely used for electricity generation and heating, creating greenhouse gas emissions and other toxic pollutants, which should be minimised according to the most recent environmental legislation. The utilisation of solid fuels with biogenic origin could contribute to the minimisation of these emissions. Solid Biofuels for Energy presents the current status of the engineering disciplines in this specific area, providing an improved background on the energy exploitation options of solid biomass. Within this framework, all thematic priorities related to the solid bioenergy potential and standardisation, commercialised and emerging energy technologies, and quality of solid residues are presented. Special attention has been given to biomass co-firing with coal, since it has the highest potential for commercial application, while combustion and gasification are more promising for units of medium to small scale. This strong practical focus is evident throughout the book, particularly in discussions of: international standards for solid biofuel specifications; supply, cost and sustainability of solid biofuels; technical issues and non-technical barriers in biomass/coal co-firing; and biomass combustion and gasification characteristics.

This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.

A unique feature of this book is its focus on nanotechnological solutions for the production of bioenergy and biofuels.

This book examines recent developments in Latin American biofuel production. Taking "sustainable development" as a central theme, each chapter considers one country in the region and explores how biofuel production is evolving given concerns about food sovereignty, trade and other social issues. Environmental conservation, as well as an increasingly complex and globalized economic structure, Is also taken into account. The contributions to this volume critically explore the ways in which biofuel production in Latin America impact social, economic and environmental systems: the so-called "three pillars of sustainability". Numerous stakeholders, drawn from government, industry, civil society and academia have attempted to define "Sustainable Development" in the context of biofuel production and to operationalize it through a series of principles, criteria, and highly specific indicators. Nevertheless, it remains a fluid and contested concept with deep political and social ramifications, which each chapter explores in detail.

"House Rating Schemes" provides information to students, architects and researchers in the field of the built environment. It reviews current House Rating Schemes (HRS) used in different countries and investigates how these schemes assess the thermal performance of a house. It challenges the way that these schemes assess building energy efficiency and their inability to evaluate free running buildings which do not need an energy load for heating and cooling indoor environments. Finally, the book proposes a new index and method for HRS in which the efficiency of a house design can be evaluated with reference to its thermal performance in both free running and conditioned operation modes. The book deals with various approaches and methods for rating buildings on the basis of different indexes, with implications for both energy efficiency and thermal comfort. It also guides readers through a computer simulation program for developing a rating system that evaluates and ranks building energy efficiency.

This book unpacks the politics of climate change in Australia in the context of successive conservative Coalition governments resisting any moves to mitigate emissions and as local communities and transnational corporations struggle with each other to control the transition to a sustainable energy future. As Australia has abundant clean energy resources in terms of solar and wind, the book offers a test case for study of the energy policy transition in the 21st century. It does so by using tools from political economy and sociology, teasing out public attitudes to renewable energy technologies and innovative infrastructure investments, unpacking the complex parameters of this historical debate, tracing the rise of household 'prosumers' and arguing the case for grassroots ownership of renewable infrastructure or 'energy sovereignty' - already pioneered by some isolated communities in Australia. The cultural and emancipatory benefits of cooperative ventures are well known. However, capitalism is not readily defeated by democracy. The promotion of individual households as 'virtual power stations', of 'smart technologies' and even of cryptocurrency into the energy transition innovative mix opens up ever new horizons for corporate control.
