Renewable Energy : Power for a Sustainable Future
The provision of sustainable energy supplies for an expanding and increasingly productive world is one of the major issues facing civilisation today. Renewable Energy examines both the practical and economic potential of the renewable energy sources to meet this challenge.The underlying physical and technological principles behind deriving power from direct solar (solar thermal and photovoltaics), indirect solar (biomass, hydro, wind and wave) and non-solar (tidal and geothermal) energy sources are explained, within the context of their environmental impacts, their economics and their future prospects. Renewable Energy provides both perspective and detail on the relative merits and state of progress of technologies for utilizing the various 'renewables'.The analysis considers emissions, sustainability, cost implications and energy security, as political and economic pressures move society towards a low-carbon future.From an overview of basic energy conversion processes, through a discussion of the individual renewable sources, to a concluding examination of the prospects for their integration into national and international networks and the outlook for renewable energy, this book provides a valuable insight into prospects for the renewables. Online resources Renewable Energy is accompanied by online resources which include: For students:· Auto- marked multiple choice questions to accompany each chapter· Curated links to further information and up-to-date energy statistics.For registered adopters of the book:· Figures from the book: available to download for use in lectures

Often I Am Happy
When Ellinor addresses her best friend Anna, she does not expect a reply.Anna has been dead for forty years, killed in the same skiing accident that claimed Henning: Ellinor’s first husband and Anna’s lover. Ellinor instead tells her that Georg has died – Georg who was once Anna’s, but whom Ellinor came to love in her place, and whom she came to care for, along with Anna’s two infant sons.Yet with Georg’s death Ellinor finds herself able to cut the ties of her assumed life with surprising ease. Returning to the area of Copenhagen where she grew up, away from the adopted comfort of the home she shared with Georg, Ellinor finds herself addressing her own history: her marriage to Henning, their seemingly charmed friendship with the newly-wed Anna and Georg, right back to her own mother's story – a story of heartbreaking pride. Because there are some secrets – both our own and of others – that we can only share with the dead.Secrets that nonetheless shape who we are and who we love.Often I Am Happy by Jens Christian Grøndahl is a profoundly moving work of fiction.

Little and Often : A Memoir
A USA TODAY BEST BOOK OF THE YEAR (????)“Little and Often is a beautiful memoir of grief, love, the shattered bond between a father and son, and the resurrection of a broken heart.Trent Preszler tells his story with the same level of art and craftsmanship that he brings to his boat making, and he reminds us of creativity’s power to transform and heal our lives.This is a powerful and deeply moving book. I won’t soon forget it.” —Elizabeth GilbertTrent Preszler thought he was living the life he always wanted, with a job at a winery and a seaside Long Island home, when he was called back to the life he left behind.After years of estrangement, his cancer-stricken father had invited him to South Dakota for Thanksgiving.It would be the last time he saw his father alive. Preszler’s only inheritance was a beat-up wooden toolbox that had belonged to his father, who was a cattle rancher, rodeo champion, and Vietnam War Bronze Star Medal recipient.This family heirloom befuddled Preszler. He did not work with his hands—but maybe that was the point.In his grief, he wondered if there was still a way to understand his father, and with that came an epiphany: he would make something with his inheritance.Having no experience or training in woodcraft, driven only by blind will, he decided to build a wooden canoe, and he would aim to paddle it on the first anniversary of his father’s death. While Preszler taught himself how to use his father’s tools, he confronted unexpected revelations about his father’s secret history and his own struggle for self-respect.The grueling challenges of boatbuilding tested his limits, but the canoe became his sole consolation.Gradually, Preszler learned what working with his hands offered: a different perspective on life, and the means to change it. Little and Often is an unflinching account of bereavement and a stirring reflection on the complexities of inheritance.Between his past and his present, and between America’s heartland and its coasts, Preszler shows how one can achieve reconciliation through the healing power of creativity. “Insightful, lyrical…Little and Often proves to be a rich tale of self-discovery and reconciliation.Resonating with Robert Pirsig’s classic Zen and the Art of Motorcycle Maintenance, it is a profound father-and-son odyssey that discovers the importance of the beauty of imperfection and small triumphs that make extraordinary happen.” —USA Today (????)

Is solar energy renewable?
Yes, solar energy is renewable because it is derived from the sun, which is a virtually limitless source of energy. The sun's energy is constantly being replenished and will continue to do so for billions of years. This makes solar energy a sustainable and renewable source of power that can be harnessed for electricity generation and other applications.
-
What is renewable energy?
Renewable energy is energy that is collected from resources that are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. These sources of energy are considered sustainable because they are naturally replenished and do not deplete finite resources. Renewable energy is seen as a cleaner and more environmentally friendly alternative to fossil fuels, as it produces lower levels of greenhouse gas emissions and reduces our dependence on non-renewable resources.
-
What are renewable resources and renewable energy sources?
Renewable resources are natural resources that can be replenished or regenerated over time, such as sunlight, wind, and water. Renewable energy sources are sources of energy that come from these renewable resources, such as solar power, wind power, hydropower, and geothermal energy. These sources of energy are considered sustainable and environmentally friendly because they do not deplete the Earth's resources and produce lower levels of greenhouse gas emissions compared to fossil fuels.
-
What are renewable and non-renewable energy sources?
Renewable energy sources are those that can be replenished naturally and are not depleted when used, such as solar, wind, hydro, and geothermal energy. These sources are sustainable and have minimal impact on the environment. Non-renewable energy sources, on the other hand, are finite and cannot be replenished in a short period of time, such as fossil fuels like coal, oil, and natural gas. These sources are not sustainable and contribute to environmental pollution and climate change.

Are renewable resources the same as sustainable resources?
Renewable resources and sustainable resources are related concepts but not exactly the same. Renewable resources are those that can be replenished naturally over time, such as sunlight, wind, and water. Sustainable resources, on the other hand, refer to resources that are managed in a way that meets current needs without compromising the ability of future generations to meet their own needs. While renewable resources are often considered sustainable, not all sustainable resources are necessarily renewable, as some non-renewable resources can be managed in a way that ensures their long-term availability.
-
Is nuclear energy a renewable energy source?
No, nuclear energy is not considered a renewable energy source. While nuclear power plants do not emit greenhouse gases during operation, they rely on uranium as a fuel source, which is a finite resource. Once uranium is used up, it cannot be replaced, making nuclear energy non-renewable. Additionally, the process of mining and refining uranium can have negative environmental impacts.
-
Does renewable energy generate energy or electricity?
Renewable energy generates electricity. Renewable energy sources such as solar, wind, hydro, and geothermal power are used to generate electricity through various technologies. For example, solar panels convert sunlight into electricity, wind turbines harness the power of the wind to generate electricity, and hydroelectric power plants use the energy of flowing water to produce electricity. Therefore, renewable energy is a key source of electricity generation that can help reduce reliance on fossil fuels and mitigate climate change.
-
What are renewable and non-renewable sources of energy?
Renewable sources of energy are resources that can be naturally replenished over time, such as sunlight, wind, and water. These sources are sustainable and do not deplete the Earth's resources. Non-renewable sources of energy, on the other hand, are finite and cannot be easily replenished, such as fossil fuels like coal, oil, and natural gas. These sources are being depleted at a faster rate than they can be replenished, leading to environmental concerns and the need to transition to more sustainable energy sources.
