Renewable Energy and Wildlife Conservation (Wildlife Management and Conservation)

by Christopher E. Moorman Steven M. Grodsky Susan Rupp

Brings together disparate conversations about wildlife conservation and renewable energy, suggesting ways these two critical fields can work hand in hand.Renewable energy is often termed simply "green energy," but its effects on wildlife and other forms of biodiversity can be quite complex. While capturing renewable resources like wind, solar, and energy from biomass can require more land than fossil fuel production, potentially displacing wildlife habitat, renewable energy infrastructure can also create habitat and promote species health when thoughtfully implemented.The authors of Renewable Energy and Wildlife Conservation argue that in order to achieve a balanced plan for addressing these two crucially important sustainability issues, our actions at the nexus of these fields must be directed by current scientific information related to the ecological effects of renewable energy production. Synthesizing an extensive, rapidly growing base of research and insights from practitioners into a single, comprehensive resource, contributors to this volume• describe processes to generate renewable energy, focusing on the Big Four renewables—wind, bioenergy, solar energy, and hydroelectric power• review the documented effects of renewable energy production on wildlife and wildlife habitats• consider current and future policy directives, suggesting ways industrial-scale renewables production can be developed to minimize harm to wildlife populations• explain recent advances in renewable power technologies• identify urgent research needs at the intersection of renewables and wildlife conservationRelevant to policy makers and industry professionals—many of whom believe renewables are the best path forward as the world seeks to meet its expanding energy needs—and wildlife conservationists—many of whom are alarmed at the rate of renewables-related habitat conversion—this detailed book culminates with a chapter underscoring emerging opportunities in renewable energy ecology.Contributors: Edward B.

Renewable Energy Desalination

by Bekele Debele Negewo

The Middle East and North Africa (MENA) Region is one of the most water stressed regions in the world. Water scarcity has already become a challenge to development in many of the countries. Due to increasing population and Projected climate change impacts, MENA's annual water demand gap is projected to grow five-fold by 2050, from today's 42 Km3 to 200 km3 by 2050. Despite its extreme scarcity, water is managed poorly. Inefficiencies are common in the agriculture, municipal and industrial systems; and many utilities are financially unsustainable. As a result, countries overexploit their fossil aquifers-and use desalination by fossil fuel-to meet the water demand gap. Desalination already plays a critical role in MENA's water supply portfolio. However, desalination is costly, energy intensive and has environmental impacts. On current trends, the projection is that, by 2050, Saudi Arabia and many other countries in the Region will consume for desalination most of the oil that they produce. Overexploitation of fossil aquifers is not sustainable. Neither is the use of fossil fuel for desalination to meet the growing water gap sustainable. This book outlines the challenges in terms of water (and also in terms of energy) that countries in the Region face and analyzes the scope of available options to address the growing water gap. The book estimates MENA's water gap today and into the future-until 2050; and presents a methodology to prioritize options to bridge the water gap, using the 'marginal cost of water' approach. The book also assesses the viability of renewable energy desalination as an important option to close the Region's water gap. The book compares the economic cost of desalination using fossil fuel and renewable energy sources, in particular the Concentrated Solar Power (CSP). The book also provides recommendations as to how CSP based desalination could ensure sustainable water supply for the Region.

Renewable Energy Generation and Value Addition from Environmental Microfiber Pollution Through Advanced Greener Solution (Environmental Science and Engineering)

by Alok Prasad Das Ipsita Dipamitra Behera Narayan Prasad Das

The majority of clothes we use regularly are made up of plastic-based materials like polyester, rayon, nylon, and acrylic. When these garments are washed in laundries, they give out tiny plastic fragments termed microfibers which end up in the environment and more precisely in the oceans. Plastic and synthetic polymer wastes which are often irresponsibly discarded into natural habitats undergo bio-fragmentation to give out huge amounts of microplastics and microfibers. Synthetic microfiber pollution has been reported in diverse ecosystems ranging from land and aquatic ecosystem to shorelines and seafloors. Due to the miniature size of the microfibers, it is difficult to detect, investigate, and prevent this type of pollution that is occurring on a larger scale. It is estimated that millions of tons of microfibers are released into the ocean from various sources. They are more toxic because they are more persistent and take a long time to degrade, and it gets accumulated in the environment along with other pollutants. This increases the chances of living organisms in the biosphere ingesting the synthetic microfibers causing harm to the ecosystem and entering into the food chain adversely affecting human beings. It had become a great field of research because of its abundance and the challenges in the identification of synthetic and semisynthetic microfibers from the environmental samples and the time it takes to be degraded. This book focuses on renewable energy generation and value addition from environmental microfiber pollution through advanced greener solution, thus building an economic supportable society as an elementary need of developing countries.

Renewable Energy Governance

by Evanthie Michalena Jeremy Maxwell Hills

This book focuses on Renewable Energy (RE) governance - the institutions, plans, policies and stakeholders that are involved in RE implementation - and the complexities and challenges associated with this much discussed energy area. Whilst RE technologies have advanced and become cheaper, governance schemes rarely support those technologies in an efficient and cost-effective way. To illustrate the problem, global case-studies delicately demonstrate successes and failures of renewable energy governance. RE here is considered from a number of perspectives: as a regional geopolitical agent, as a tool to meet national RE targets and as a promoter of local development. The book considers daring insights on RE transitions, governmental policies as well as financial tools, such as Feed-in-Tariffs; along with their inefficiencies and costs. This comprehensive probing of RE concludes with a treatment of what we call the "Mega-What" question - who is benefitting the most from RE and how society can get the best deal? After reading this book, the reader will have been in contact with all aspects of RE governance and be closer to the pulse of RE mechanisms. The reader should also be able to contribute more critically to the dialogue about RE rather than just reinforce the well-worn adage that "RE is a good thing to happen".

Renewable Energy in the Countryside

by Peter Prag

Climate change has become a major international issue and the British Government is committed to meeting ambitious targets for reducing greenhouse gas emissions within the present decade and beyond. Much of this will rely on an increasing use of renewable energy. Within current technology this will depend almost exclusively upon the use of rural land, whether for wind turbines, for growing biomass and biofuels or for the production of biogas. Renewable energy is therefore of immediate interest to farmers and landowners and to their advisers, such as surveyors, lawyers, accountants and bankers, as well as to planners and conservationists. This is one of very few books which addresses the issue of renewable energy from the point of view of landowners, farmers and rural land managers – those people who must make important decisions about how, where and when to install renewable energy sources on their land and the business implications of the decisions they make. The third edition of Renewable Energy in the Countryside contains a new chapter on biogas, up-to-date discussions on the implications of the Renewable Heat Initiative and new opportunities for solar energy and ground source heat in the context of farms and country houses as well as the implications of changes in UK planning policies.

Renewable Energy in the Middle East

by Michael Mason Amit Mor

Energy insecurity is not normally associated with the Middle East. However, away from the oil-rich Persian Gulf, the countries of the eastern Mediterranean are particularly vulnerable. Their fossil fuel endowments are low, while their fractious relationships with each other have long fostered wider political insecurities. Focusing on the Jordan Basin (Israel, the Palestinian Territories, Lebanon and Jordan), this timely volume addresses the prospects for the adoption of renewable energy in the oil-poor Middle East. Featuring regional energy experts, it offers an invaluable survey. After outlining the regional security context, this book first reviews renewable energy policy and practices in the Jordan Basin. It then considers options for greening energy use, including promising pilot projects in North Africa. The initiatives discussed encompass renewable energy finance, energy-efficient rural communities, and solar and wind energy. There is significant potential for an increase in the uptake of renewable energy technologies in the eastern Mediterranean. This window of opportunity has been created by high oil prices, energy infrastructure investment opportunities, and the UN climate change regime. In conclusion, the book considers the institutional conditions for collaborative decision-making on renewable energy. Such cooperation would deliver substantial security and human development benefits to the region, and indeed the world.
