Renewable Energy Sources and Climate Change Mitigation
Author: Ottmar Edenhofer
Publisher: Cambridge University Press
ISBN: 9781107607101
Category : Science
Languages : en
Pages : 1088
Book Description
This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.

Renewable Energy
Author: Robert Ehrlich
Publisher: CRC Press
ISBN: 1439861153
Category : Technology & Engineering
Languages : en
Pages : 466
Book Description
Renewable energy has great significance for the world’s future, given the environmental issues related to energy generation and energy’s importance in our society. Making wise energy choices is not easy, however. It involves balanced consideration of economic, environmental, technical, political, and other perspectives to weigh the relative costs and benefits for a host of possible technologies. Renewable Energy: A First Course is an accessible textbook for science and engineering students who want a well-balanced introduction to the science, technologies, economics, and policies related to energy choices. How Does Renewable Energy Work? Science, Technologies, Economics, and Key Policy Issues The book delves into all forms of renewable energy, from biofuels and geothermal energy to wind, hydro, and solar power. It also discusses nuclear power and fossil fuels, allowing readers to compare and evaluate the advantages and shortcomings of renewable energy. In addition, the book explores four overarching topics that go beyond a specific type of energy, namely, energy conservation, energy storage, energy transmission, and energy policy, and examines the important issue of climate change. A Broad Introduction for Science and Engineering Students Requiring only a basic background in physics and calculus, the book avoids technical jargon and advanced mathematical approaches to focus on the basic principles of renewable energy. Throughout, a wealth of illustrations and real-world examples make the concepts more concrete. Designed for a one- or two-semester course, this book takes a broad approach that addresses the need for diversity in any nation’s energy portfolio.
