Chapter 11 Carbon Capture and Storage -Technologies and Risk Management 237 Victor Esteves and Cláudia Morgado Chapter 12 Energy and Economy Links -A Review of Indicators and Methods 265 Mohammad Reza Lotfalipour and Malihe Ashena Chapter 13 Fossil Fuel and Food Security 279 Richard E. White X PrefaceDepleting fossil fuel raises valid concerns about ongoing shortages and availability for future generations. Estimates of current and future reserves of oil and gas are conflicting, given the data by commercial companies, government organizations, and academia. It is clear that increasing prices, coupled with the importance of oil to the chemical industry will ensure that oil will continue to be produced at higher expense for a very long time.The readers will find 13 chapters in the book. The topics move mostly seamlessly from conventional fuel to alternative energy, to the environment, and finally to economics and food security.The book starts with conventional topics of fuel properties, combustion and deposition, and co-combustion with alternative fuels. It discusses operator training, power stations, and distributed power systems. There are also discussed some estimates of remaining fuel reserves, electric vehicles, and environmental issues. Chapters on sending emissions back underground, though somewhat futuristic, define the borders of current research, and the importance of reducing greenhouse gas emissions.The research on fossil fuel and the environment defines much of the range of today's scientific knowledge, and is a major driving force of modern progress. The ideas and data here, however, humble they may seem, are potentially far reaching and profound, considering the billions of dollars of fuel, its tankers and pipelines and the global geopolitics, that are shaping the world. Whether feasible or futuristic, this book is a great read for researchers, practitioners, policymakers, or just about anyone with an enquiring mind on this subject.I take this opportunity to thank Intech Publisher, whose vision on open-access publishing has in a few short years brought cutting-edge research to the academic community worldwide.This book acknowledges and recognizes all the researchers, who have dedicated their lives to the betterment of mankind as well their work on the topic of fossil fuel and the environment. It is a tribute to those, whose tireless pursuit of a new knowledge on energy has been the driving force of modern progress.
