Energy Return on Investment
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” ar...
Energy and the Wealth of Nations
In this updated edition of a groundbreaking text, concepts such as energy return on investment (EROI) provide powerful insights into the real balance sheets that drive our “petroleum economy.” Hall and Klitgaard explore the relation between energy and the wealth explosion of the 20th century, and the interaction of internal limits to growth found in the investment process and rising inequality with the biophysical limits posed by finite energy resources. The authors focus attention on the failure of markets to recognize or efficiently allocate diminishing resources, the economic consequences of peak oil, the high cost and relatively low EROI of finding and exploiting new oil fields, incl...

How Now Shall We Live?
2000 Gold Medallion Award winner! Christianity is more than a personal relationship with Jesus Christ. It is also a worldview that not only answers life's basic questions—Where did we come from, and who are we? What has gone wrong with the world? What can we do to fix it?—but also shows us how we should live as a result of those answers. How Now Shall We Live? gives Christians the understanding, the confidence, and the tools to confront the world's bankrupt worldviews and to restore and redeem every aspect of contemporary culture: family, education, ethics, work, law, politics, science, art, music. This book will change every Christian who reads it. It will change the church in the new millennium.
We Shall See God
No author in history has more material in print than Charles Spurgeon. During his lifetime, Spurgeon and his writings affected the world far and wide. Today, nearly 120 years after his death, countless people continue to have a passion for this London preacher, and more and more discover him every day. Some of Spurgeon’s most powerful sermons were those that he preached on the topic of Heaven. Up until now, however, very few of these sermons have been accessible to a mass audience. In what is sure to become an instant classic, best-selling author Randy Alcorn has compiled the most profound spiritual insights on the topic of eternity from these sermons and arranged them into an easily-accessible, highly inspirational devotional format complete with his own comments and devotional thoughts. Whether you are familiar with the works of Charles Spurgeon or not, you are in for a treat, as Alcorn invites you to sit at the feet of the Prince of Preachers and discover timeless pearls of wisdom from one of the greatest theological minds of all time.
Spain’s Photovoltaic Revolution
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, r...
