Seminar paper from the year 2016 in the subject Engineering - Power Engineering, grade: 1,0, Technical University of Munich (Department of Electrical and Computer Engineering), course: Advanced Seminar on Renewable and Sustainable Energy Systems, language: English, abstract: This paper is about the energy return of investment. Energy has a significant impact on economic growth and is a key driver for the wellbeing of a society. The less a society has to spend on energy, the more remains for consumption and discretionary spending that is directly translated into economic growth. This impact can be assessed with the help of the net energy analysis that makes use of the concept of EROI. The Energy Return On Investment is the ratio of the quantity of energy delivered to the quantity of energy consumed in a given process. Thus, this metric serves to measure the accessibility of a resource, meaning that the higher the EROI, the greater the amount of net energy delivered to society in order to support economic growth. This goes hand in hand with the finding that there is a minimum level of EROI that has to be reached, otherwise economic growth cannot be possible. Given that net energy analysis is going to be one of the most fundamental concepts in academic and policy discussion in view of the future of the energy mix there is still a clear need for a standardized and independent framework to calculate EROI.

This authoritative but highly accessible book presents the reader with a powerful framework for understanding the critical role of the energy return on investment (EROI) in the survival and well-being of individuals, ecosystems, businesses, economies and nations. Growth and development are fundamental and ubiquitous processes at all scales, from individuals to food crops to national economies. While we are all familiar with the concepts of economic growth and living standards as measured by gross domestic product (GDP), we often take for granted the energy use that underpins GDP and our expectations for year-on-year growth. In this book, you will learn how these measures of “progress” are completely dependent on the balance that can be achieved between energy costs (inputs) and gains. Nothing is made or moved without an energy surplus, and it is the EROI of available energy sources more than any other single factor that determines the shape of civilization. Nearly all politics and economics assume that policy and market forces are the levers upon which future outcomes will hinge. However, this book presents many examples of historical and current events that can be explained much more clearly from an energetic perspective. In addition, a future scenario is developed that gives a central place to EROI in assessing the potential of governmental and private initiatives to substitute so-called renewable energy sources for diminishing stocks of fossil fuels. When cheap fossil fuels are no longer available in the abundance needed to mask economic problems and power business as usual, it will be EROI more than the plethora of “green” technologies that creates the boundary conditions for a sustainable future.

The Energy Return on Energy Invested (EROI or EROEI) is the amount of energy acquired from a particular energy source divided by the energy expended, or invested, in obtaining that energy. EROI is an essential and seemingly simple measure of the usable energy or “energy profit” from the exploitation of an energy source, but it is not so easy to determine all of the energy expenditures that should be included in the calculation. Because EROI values are generally low for renewable energy sources, differences in these estimates can lead to sharply divergent conclusions about the viability of these energy technologies. This book presents the first complete energy analysis of a large-scale, real-world deployment of photovoltaic (PV) collection systems representing 3.5 GW of installed, grid-connected solar plants in Spain. The analysis includes all of the factors that limit and adjust the real electricity output through one full-year cycle, and all of the fossil fuel inputs required to achieve these results. The authors’ comprehensive analysis of energy inputs, which assigns energy cost estimates to all financial expenditures, yields EROI values that are less than half of those claimed by other investigators and by the solar industry. Sensitivity analysis is used to test various assumptions in deriving these EROI estimates. The results imply that the EROI of current, large-scale PV systems may be too low to seamlessly support an energy and economic transition away from fossil fuels. Given the pervasiveness of fossil fuel subsidies in the modern economy, a key conclusion is that all components of the system that brings solar power to the consumer, from manufacturing to product maintenance and life cycle, must be improved in terms of energy efficiency. The materials science of solar conversion efficiency is only one such component. Sunny Spain represented an ideal case study as the country had the highest penetration of solar PV energy at 2.3 percent of total national demand as well as state-of-the-art expertise in solar power including grid management of intermittent, modern renewable systems. This book, written by a uniquely qualified author team consisting of the chief engineer for several major photovoltaic projects in Spain and the world’s leading expert on the concept and application of EROI, provides a comprehensive understanding of the net energy available to society from energy sources in general and from functioning PV installations under real-world conditions in particular. The authors provide critical insight into the capacity of renewable energy sources to fill the foreseeable gap between world energy demand and depletion rates for fossil fuels. · Presents the first comprehensive study of the EROI of large-scale solar PV systems in a developed country · Uses real-world operational data rather than laboratory approximations and extrapolations · Describes the dependence of one alternative energy source on the goods and services of a fossil-fueled economy · Has global implications for the potential of renewable energy sources to replace dwindling reserves of fossil fuels · Written with the first-hand knowledge of the chief, on-site engineer for many solar installations in Spain together with the leader in the development and application of the concept of EROI

"We face three epoch-defining environmental problems: climate, extinction and pestilence. Our climate is changing in ways that will have serious consequences for humans, and may even profoundly affect the ability of the planet to support life. All around us, other species are disappearing at a rate between several hundred and several thousand times the normal background rate of extinction. The SARS-CoV-2 virus, which has wreaked social and economic havoc, is merely the latest model off a blossoming production line of newly emerging infectious diseases, many of which have the potential to be far worse. At the heart of these problems lies an ancient habit: eating animals. This habit is the most significant driver of species extinction and of newly emerging infectious diseases, and one of the most important drivers of climate change. This is a habit we can no longer afford to indulge. Breaking it will substantially reduce climate emissions. It will stem our insatiable hunger for land that is at the heart of both the problems of extinction and pestilence. Most importantly, breaking this habit will make available vast areas of land suitable for afforestation: the return of forests to where they once grew. Afforestation will significantly mitigate all three problems. But only if we stop eating animals will we have enough land for this strategy to work"--

This book provides a thought provoking outline of the solutions already in hand to the challenges now facing humanity with respect to prevalent gross social and economic inequalities, ecological thresholds and tipping points, and the ever-looming threat of climate catastrophe. The authors find these solutions in the arenas of renewable energy systems, agroecological methods, and reimagined social organization. Clarity is brought to the political economic obstacles standing in the way as well as the false solutions and alleged barriers that pervade the discourse thereby delaying and obstructing progress to the solutions advanced.The authors provoke readers to face up to these challenges by demonstrating how people, all over the world, have already begun this effort through collective action ranging from the local to the global community. Drawing on their own and many other scholar's research, they reject a reliance on the 'business as usual' approach trusting the capitalist market and existing global institutions, and provide an accessible popular account with thoroughly footnoted endnotes that contain technical details and references to the scientific literature.The Earth is Not for Sale informs its readers and provides well-documented solutions in a bid to inspire readers to think critically, and potentially become more active in society.

Energy drives the economy, economics informs policy, and policy affects social outcomes. Since the oil crises of the 1970s, pundits have debated the validity of this sequence, but most economists and politicians still ignore it. Thus, they delude the public about the underlying influence of energy costs and constraints on economic policies that address such pressing contemporary issues as income inequality, growth, debt, and climate change. To understand why, Carey King explores the scientific and rhetorical basis of the competing narratives both within and between energy technology and economics. Energy and economic discourse seems to mirror Newton’s 3rd Law of Motion: For every narrative there is an equal and opposite counter-narrative. The competing energy narratives pit "drill, baby, drill!" against renewable technologies such as wind and solar. Both claim to provide secure, reliable, clean, and affordable energy to support economic growth with the most benefit to society, but how? To answer this question, we need to understand the competing economic narratives, techno-optimism and techno-realism. Techno-optimism claims that innovation overcomes any physical resource constraints and enables the social outcomes and economic growth we desire. Techno-realism, in contrast, states that no matter what energy technologies we use, feedbacks from physical growth on a finite planet constrain economic growth and create an uneven distribution of social impacts. In The Economic Superorganism, you will discover stories, data, science, and philosophy to guide you through the arguments from competing narratives on energy, growth, and policy. You will be able to distinguish the technically possible from the socially viable, and understand how our future depends on this distinction.

The book is about global energy use, its past and present, and its increasingly uncertain future. It lists the various ecological problems facing our planet, not just climate change, and how their gravity has been underestimated. It briefly looks at the various solutions, apart from renewable energy, proposed for solving the problems our present energy use raises, including solar radiation management, carbon dioxide removal, nuclear energy, and energy efficiency. Renewable energy (RE) is seen by many as the panacea for a variety of environmental challenges, and with the New Green Deal, even as a means of accelerating economic growth. The book critically examines the prospects for RE. It concludes that although it is essential that the world shifts to RE, not only will the ecologically sustainable energy from all RE sources likely fall well short of even present global energy use, but the very short time frame left for effective action means that RE cannot be more than of minor help. Hence, deep energy reductions will be needed, especially in high-income OECD countries. The book uses an Earth Systems Science approach, which is necessary because of the interconnection between the various challenges our Earth faces. It aims to combine the latest findings from a diverse array of biophysical as well as socioeconomic sciences to uncover the increasingly constrained energy options we will encounter.
