Book Description
Here is the truth that the powerful Dirty Energy public relations machine doesn't want you to know: the ascent of solar energy is upon us. Solar-generated electricity has risen exponentially in the last few years and employment in the solar industry has doubled since 2009. Meanwhile, electricity from coal has declined to pre-World War II levels as the fossil fuel industry continues to shed jobs. Danny Kennedy systematically refutes the lies spread by solar's opponents—that it is expensive, inefficient, and unreliable; that it is kept alive only by subsidies; that it can't be scaled; and many other untruths. He shows that we need a rooftop revolution to break the entrenched power of the coal, oil, nuclear, and gas industries Solar energy can create more jobs, return our nation to prosperity, and ensure the sustainability and safety of our planet. Now is the time to move away from the dangerous energy sources of the past and unleash the amazing potential of the sun.

Book Description
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

Book Description
The UK has, in recent years, been suffering from what is nothing short of an economic crisis. Growth has now completely stalled in those western democracies, the UK included, where high government spending and high taxes have steadily burgeoned, decade after decade. Free-market economies now threaten to leave us behind in terms of wealth, opportunity and standards of living. At the end of Rishi Sunak's 2024 government, expenditure was at 45 per cent of GDP and taxes were 36 per cent and rising – yet still nowhere near sufficient to cover public expenditure. The government's net annual borrowing is now a completely unsustainable 4.4 per cent of GDP, with our overall national debt growing rapidly and alarmingly. In this arresting and powerful manifesto for economic change, Jon Moynihan analyses the UK's decades-long stagnant economy and looks at what can be done to resuscitate it. Combining rigorous research with unparalleled business experience, he explores the key dynamics affecting economic growth, ranging from government borrowing, expenditure, tax and regulation to the way national resources are deployed on non-productive and futile, growth-stifling endeavours. Ultimately, Moynihan shows that unless we act now to reverse the decline, by radically restructuring our economy to stimulate economic growth, the UK risks stagnation, financial collapse and a long-term disintegration in our standard of living. Ignore his warning at your peril.

From "a striking new talent"(Sandra Dallas, author of Tallgrass) comes an unforgettable debut novel of young love and coming of age in an Iran headed toward revolution. In this poignant, eye-opening and emotionally vivid novel, Mahbod Seraji lays bare the beauty and brutality of the centuries-old Persian culture, while reaffirming the human experiences we all share. In a middle-class neighborhood of Iran's sprawling capital city, 17-year-old Pasha Shahed spends the summer of 1973 on his rooftop with his best friend Ahmed, joking around one minute and asking burning questions about life the next. He also hides a secret love for his beautiful neighbor Zari, who has been betrothed since birth to another man. But the bliss of Pasha and Zari's stolen time together is shattered when Pasha unwittingly acts as a beacon for the Shah's secret police. The violent consequences awaken him to the reality of living under a powerful despot, and lead Zari to make a shocking choice...
