Download or read book Drawdown written by Paul Hawken and published by Penguin. This book was released on 2017-04-18 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: • New York Times bestseller • The 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world “At this point in time, the Drawdown book is exactly what is needed; a credible, conservative solution-by-solution narrative that we can do it. Reading it is an effective inoculation against the widespread perception of doom that humanity cannot and will not solve the climate crisis. Reported by-effects include increased determination and a sense of grounded hope.” —Per Espen Stoknes, Author, What We Think About When We Try Not To Think About Global Warming “There’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors. At least until now. . . . The public is hungry for this kind of practical wisdom.” —David Roberts, Vox “This is the ideal environmental sciences textbook—only it is too interesting and inspiring to be called a textbook.” —Peter Kareiva, Director of the Institute of the Environment and Sustainability, UCLA In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.
Download or read book Impact on Energy Consumption and Environmental Degradation by Switching of Refrigerants in Small Scale Commercial Refrigeration Units written by Anant Wadhwa and published by GRIN Verlag. This book was released on 2020-06-23 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2019 in the subject Engineering - Power Engineering, , language: English, abstract: World population has reached 7 billion people in 2013 and there has been an increase in energy consumption, especially in emerging countries. In 2050 it will be more than 9 billion people living on the planet. Because of this, there has been a rapid increase in CO2 concentration levels, so the average planet temperature is rising, causing a greenhouse effect, as the CO2 is trapping in the heat and not releasing it. Consequently, ocean levels are rising, because of the shrinking polar ice caps. We also have seen an increase in the frequency of extreme atmosphere events around the globe. The refrigeration industry has contributed a lot to the global ozone depletion and global warming. To reduce the environmental impact by the heating, ventilation, air conditioning and refrigeration industry – both commercial and domestic – there is an urgent need to look for solutions that are both ozone friendly and CO2 friendly (greenhouse effect friendly). Eradicating the damage to the environment has encouraged the industrial and commercial refrigeration industry to investigate refrigerant alternatives that reduce the environmental impact although a good transition to them will also depend on the training that technicians acquire, as well as the understanding of the current and future benefits for the companies and the end users. This thesis aims at such a system which is both above mentioned. Once such a system is designed, it is of the utmost importance to test it and compare it with the systems that are being used currently to assess the benefits of using such system. The thesis has a focus on the liquid cooling systems such as water coolers and small commercial systems that help attain cooling of the liquids to a set temperature. In this thesis, the improvement of energy consumption and environmental degradation prevention is attained by switching the refrigerant used from R134a (current) to R290 (Propane) which is a natural refrigerant and Hydro Carbon Blend which is a mixture of refrigerants but is safer and environmentally friendlier. A comparison of both systems is done against the current system in terms of efficiency, energy consumption and chemical properties with respect to global warming potential and ozone depletion potential and ultimately proven that natural refrigerants and HC Blends are the refrigerants of the future.

Download or read book After Cooling written by Eric Dean Wilson and published by Simon and Schuster. This book was released on 2022-07-19 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This “ambitious [and] delightful” (The New York Times) work of literary nonfiction interweaves the science and history of the powerful refrigerant (and dangerous greenhouse gas) Freon with a haunting meditation on how to live meaningfully and morally in a rapidly heating world. In After Cooling, Eric Dean Wilson braids together air-conditioning history, climate science, road trips, and philosophy to tell the story of the birth, life, and afterlife of Freon, the refrigerant that ripped a hole larger than the continental United States in the ozone layer. As he traces the refrigerant’s life span from its invention in the 1920s—when it was hailed as a miracle of scientific progress—to efforts in the 1980s to ban the chemical (and the resulting political backlash), Wilson finds himself on a journey through the American heartland, trailing a man who buys up old tanks of Freon stockpiled in attics and basements to destroy what remains of the chemical before it can do further harm. Wilson is at heart an essayist, looking far and wide to tease out what particular forces in American culture—in capitalism, in systemic racism, in our values—combined to lead us into the Freon crisis and then out. “Meticulously researched and engagingly written” (Amitav Ghosh), this “knockout debut” (New York Journal of Books) offers a rare glimpse of environmental hope, suggesting that maybe the vast and terrifying problem of global warming is not beyond our grasp to face.

Download or read book Refrigeration Air Conditioning and Heat Pumps written by Fabio Polonara and published by MDPI. This book was released on 2021-02-11 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Refrigeration, air conditioning, and heat pumps (RACHP) have an important impact on the final energy uses of many sectors of modern society, such as residential, commercial, industrial, transport, and automotive. Moreover, RACHP also have an important environmental impact due to the working fluids that deplete the stratospheric ozone layer, which are being phased out according to the Montreal Protocol (1989). Last, but not least, high global working potential (GWP), working fluids (directly), and energy consumption (indirectly) are responsible for a non-negligible quota of greenhouse gas (GHG) emissions in the atmosphere, thus impacting climate change.

Available in PDF, EPUB and Kindle. Book excerpt: The HVAC (Heating, Ventilation, and Air Conditioning) industry plays a critical role in modern society, providing comfort, safety, and productivity in residential, commercial, and industrial spaces. At the heart of these systems lies a vital component—refrigerants. These chemical compounds enable the transfer of heat and make the cooling and heating processes in HVAC systems possible. Yet, as essential as they are, refrigerants have been the subject of growing scrutiny due to their environmental impact. The need to balance efficiency, safety, and environmental sustainability has made refrigerants a dynamic and evolving area of study. This book is designed to provide a comprehensive overview of HVAC refrigerants, from their fundamental principles to their real-world applications. Whether you are an engineer, technician, student, or someone with a general interest in HVAC systems, this book will offer insights into the past, present, and future of refrigerants. Throughout history, refrigerants have undergone significant transformations. From the early days of chlorofluorocarbons (CFCs), which were once celebrated for their efficiency, to the environmentally damaging effects that led to their global phase-out, the evolution of refrigerants is a reflection of our growing understanding of the delicate balance between technology and the environment. Today, modern refrigerants are focused on reducing global warming potential (GWP) and minimizing ozone depletion while still delivering the high performance required in HVAC systems. This book is not just a technical manual; it’s a journey into understanding the science behind refrigeration, the regulations that govern refrigerant usage, and the innovations that will shape the future of the HVAC industry. In a time when energy efficiency and environmental sustainability are of utmost importance, selecting the right refrigerant can make a substantial difference. This decision impacts not only the performance and lifespan of HVAC systems but also the planet we share. As you read through the chapters, you will explore a wide range of refrigerants, from traditional compounds to newer, more environmentally friendly options. You’ll gain an understanding of the regulatory landscape, including global and regional regulations like the Montreal Protocol, and how they drive innovation in the industry. You'll also delve into real-world case studies, gaining practical insights into the challenges and successes associated with different refrigerant applications. In writing this book, my aim is to provide an accessible yet thorough resource on HVAC refrigerants, offering both a foundational understanding and the technical depth needed to make informed decisions in this rapidly changing field. Whether you are retrofitting an existing system, designing a new one, or simply interested in the future of HVAC technology, I hope this book serves as a valuable guide. The future of refrigerants is bright and full of potential, and it is my hope that this book will inspire you to take an active part in shaping that future—one that prioritizes both performance and the health of our environment.
Download or read book Health of People Health of Planet and Our Responsibility written by Wael Al-Delaimy and published by Springer Nature. This book was released on 2020-05-13 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book not only describes the challenges of climate disruption, but also presents solutions. The challenges described include air pollution, climate change, extreme weather, and related health impacts that range from heat stress, vector-borne diseases, food and water insecurity and chronic diseases to malnutrition and mental well-being. The influence of humans on climate change has been established through extensive published evidence and reports. However, the connections between climate change, the health of the planet and the impact on human health have not received the same level of attention. Therefore, the global focus on the public health impacts of climate change is a relatively recent area of interest. This focus is timely since scientists have concluded that changes in climate have led to new weather extremes such as floods, storms, heat waves, droughts and fires, in turn leading to more than 600,000 deaths and the displacement of nearly 4 billion people in the last 20 years. Previous work on the health impacts of climate change was limited mostly to epidemiologic approaches and outcomes and focused less on multidisciplinary, multi-faceted collaborations between physical scientists, public health researchers and policy makers. Further, there was little attention paid to faith-based and ethical approaches to the problem. The solutions and actions we explore in this book engage diverse sectors of civil society, faith leadership, and political leadership, all oriented by ethics, advocacy, and policy with a special focus on poor and vulnerable populations. The book highlights areas we think will resonate broadly with the public, faith leaders, researchers and students across disciplines including the humanities, and policy makers.

In order to develop any of the technologies for successful practical application, very intensive theoretical and experimental research should be conducted. This book provides the reader with a comprehensive overview of the latest developments, perspectives, and feasibility of new low-temperature technologies and improvements of existing systems, equipment, and evaluation methods.
Download or read book Refrigeration units in marine vessels written by Prof. Dr.-Ing. A. Hafner and published by Nordic Council of Ministers. This book was released on 2019-04-02 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing vessels can be equipped with energy efficient refrigeration technology applying natural working fluids. Ammonia refrigeration systems have been the first choice, but CO2 units have also become increasingly common in the maritime sector in the last few years. When retrofitting or implementing CO2 refrigeration plants, less space on board is required and such units allow good service and maintenance. Nowadays, cruise ship owners prefer CO2 units for the provision refrigeration plants.Ship owners, responsible for the health and safety of the crew and passengers, must carefully evaluate the usage of flammable low GWP working fluids, due to a high risk that toxic decomposition products are formed, even without the presence of an open flame. Suggestions for further work include a Nordic Technology Hub for global marine refrigeration R&D and development support for key components.
