Scenarios For A Clean Energy Future

"Over the next few decades, we will see a profound energy transformation as society shifts from fossil fuels to renewable resources like solar, wind, biomass. But what might a one hundred percent renewable future actually look like, and what obstacles will we face in this transition? Authors explore the practical challenges and opportunities presented by the shift to renewable energy."--Page 4 of cover.

Future Energy will allow us to make reasonable, logical and correct decisions on our future energy as a result of two of the most serious problems that the civilized world has to face; the looming shortage of oil (which supplies most of our transport fuel) and the alarming rise in atmospheric carbon dioxide over the past 50 years (resulting from the burning of oil, gas and coal and the loss of forests) that threatens to change the world’s climate through global warming. Future Energy focuses on all the types of energy available to us, taking into account a future involving a reduction in oil and gas production and the rapidly increasing amount of carbon dioxide in our atmosphere. It is unique in the genre of books of similar title in that each chapter has been written by a scientist or engineer who is an expert in his or her field. The book is divided into four sections: • Traditional Fossil Fuel and Nuclear Energy • Renewable Energy • Potentially Important New Types of Energy • New Aspects to Future Energy Usage Each chapter highlights the basic theory and implementation, scope, problems and costs associated with a particular type of energy. The traditional fuels are included because they will be with us for decades to come - but, we hope, in a cleaner form. The renewable energy types includes wind power, wave power, tidal energy, two forms of solar energy, bio-mass, hydroelectricity, geothermal and the hydrogen economy. Potentially important new types of energy include: pebble bed nuclear reactors, nuclear fusion, methane hydrates and recent developments in fuel cells and batteries. - Written by experts in the key future energy disciplines from around the globe - Details of all possible forms of energy that are and will be available globally in the next two decades - Puts each type of available energy into perspective with realistic, future options

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.

Energy production and use touch our lives in countless ways. We are reminded of the cost of energy every time we fill up at the gas pump, pay an electricity bill, or purchase an airline ticket. Energy use also has important indirect impacts, not all of which are reflected in current energy prices: depletion of natural resources, degradation of the environment, and threats to national security arising from a growing dependence on geopolitically unstable regions for some of our energy supplies. These indirect impacts could increase in the future if the demand for energy rises faster than available energy supplies. Our nation's challenge is to develop an energy portfolio that reduces these impacts while providing sufficient and affordable energy supplies to sustain our future economic prosperity. The United States has enormous economic and intellectual resources that can be brought to bear on these challenges through a sustained national effort in the decades ahead. America's Energy Future is intended to inform the development of wise energy policies by fostering a better understanding of technological options for increasing energy supplies and improving the efficiency of energy use. This summary edition of the book will also be a useful resource for professionals working in the energy industry or involved in advocacy and researchers and academics in energy-related fields of study. America's Energy Future examines the deployment potential, costs, barriers, and impacts of energy supply and end-use technologies during the next two to three decades, including energy efficiency, alternative transportation fuels, renewable energy, fossil fuel energy, and nuclear energy, as well as technologies for improving the nation's electrical transmission and distribution systems.

Analysing the interaction between energy and climate change mitigation issues requires the adoption of a long-term perspective - looking up to fifty years ahead. The future cannot be predicted, particularly over longer periods. However, strategic planning and political decisions demand that we explore options for the future - and these are best developed through scenarios (conjectures as to what might happen in the future based on our past and present experience of the world and on plausible speculation about how these trends may further evolve). This volume looks at different types of scenarios, evaluating how they can be used to analyse specific aspects of the interaction between energy and environment over the longer term. It examines "exploratory scenarios" (based on different expectations of technical and/or policy developments over the next 50 years) and "normative scenarios" (based on a set of desirable features or "norms" that the future world should possess). These long-term scenarios complement the IEA's World Energy Outlook, which presents a mid-term business-as-usual scenario with some variants.

This outlook highlights climate-safe investment options until 2050, policies for transition and specific regional challenges. It also explores options to eventually cut emissions to zero.
