Show your love for the “green planet” by increasing your knowledge on the renewable energy sources like wind, solar and hydro energy. By being aware of these alternative uses of energy, you can help campaign against the use of nonrenewable sources, and the damage they cause the environment. Fall in love with this book in either print, hardcover or digital format. Grab a copy today.
Kids will learn valuable hands-on lessons from this guide by constructing working models that generate renewable, alternative energy. Budding scientists learn how to build their own Kelvin water-drop generator out of six recycled cans and alligator-clip jumpers; a solar-powered seesaw from a large dial thermometer and a magnifying glass; and a windmill from eight yardsticks, PVC pipe, cardboard, and a converter generator. Children will investigate the energy-generating properties of a solar cell, a radiometer, a Nitinol heat engine, and a Peltier cell--there are even plans to build a human-powered desk lamp. Each project includes a materials and tools list as well as online information on where to find specialized components.
How do we heat our homes, light our rooms, and power our cars? With energy! In 2014, the United States relied on fossil fuels for about 67 percent of its power. But as the fossil fuel supply dwindles and climate change becomes an increasingly urgent issue, individuals, businesses, and governments are expanding their sources of renewable energy, including solar, wind, biofuel, hydro, and geothermal. In Renewable Energy: Discover the Fuel of the Future, readers ages 9 to 12 learn about these renewable energy sources and discover how sunshine can be used to power light bulbs and how the earth's natural heat can be used to warm our houses. Young readers weigh the pros and cons of different energy sources and make their own informed opinions about which resources are the best choices for different uses. Renewable energy industries provide a booming field for future scientists and engineers. This book shows kids these future jobs and gets them excited about contributing to a world run on clean energy. Hands-on projects, essential questions, links to online primary sources, and science-minded prompts to think more about energy, the environment, and the repercussions of our choices make this book a key addition to classrooms and libraries.
What Will Work makes a rigorous and compelling case that energy efficiencies and renewable energy-and not nuclear fission or "clean coal"-are the most effective, cheapest, and equitable solutions to the pressing problem of climate change. Kristin Shrader-Frechette, a respected environmental ethicist and scientist, makes a damning case that the only reason that debate about climate change continues is because fossil-fuel interests pay non-experts to confuse the public. She then builds a comprehensive case against the argument made by many that nuclear fission is a viable solution to the problem, arguing that data on the viability of nuclear power has been misrepresented by the nuclear industry and its supporters. In particular she says that they present deeply flawed cases that nuclear produces low greenhouse gas emissions, that it is financially responsible, that it is safe, and that its risks do not fall mainly on the poor and vulnerable. She argues convincingly that these are all completely false assumptions. Shrader-Frechette then shows that energy efficiency and renewable solutions meet all these requirements - in particular affordability, safety, and equitability. In the end, the cheapest, lowest-carbon, most-sustainable energy solutions also happen to be the most ethical. This urgent book on the most pressing issue of our time will be of interest to anyone involved in environmental and energy policy. "An extraordinary achievement by a philosopher-scientist and public intellectual. The book is unmatched in its synthesis of the empirical data, theory and ethics that infuse the climate-change debates. Its overpowering but transparent argument should be mandatory reading for every elected official. Shrader-Frechette takes practical logic and scientific transparency to new heights. The best book written in the last decade on climate change." - Sheldon Krimsky, Tufts University "Shrader-Frechette's book is outstanding. She makes a thorough review of the scientific evidence on nuclear health risks, and also explains the political and economic forces affecting public policy. Very readable for scientists, policy makers, and the public." - Joseph J. Mangano, Radiation and Public Health Project, New York "Fascinating and important! Shrader-Frechette presents the scientific, economic, and ethical evidence for the failure of nuclear power -- it is neither carbon-free nor a viable solution to the energy crisis and global warming. While explaining the nuances of the scientific, economic and ethical arguments, the author teaches the reader why solar and wind energy, along with energy efficiency changes, will yield a safe, healthy, reliable and economically efficient energy future for the planet." - Colleen F. Moore, University of Wisconsin, author of Children and Pollution: Why Scientists Disagree
Though wind power has been in use for hundreds of years, its one of todays fastest-growing energy sources. Readers will learn how we have harnessed the winds energy with everything from primitive windmills to high-tech wind farms.
Discusses alternative energy sources, including solar power, wind power, and biofuels, and the importance of developing such sustainable sources of energy.
Provides a comprehensive overview of emerging perspectives and innovations for alternative energy sources. Highlighting relevant concepts on energy efficiency, current technologies, and ongoing industry trends, this is an ideal reference source for academics, practitioners, professionals, and upper-level students interested in the latest research on renewable energy.
