دانلود کتاب Green Electricity: 25 Green Technologies That Will Electrify Your Future

Our existing electric utility industry and power supply and delivery systems are woefully outdated. Indeed, the existing power grid we use today uses 100-year-old technology! This book lays out the possible blueprints for a greener future in a way that will engage middle school learners, enabling students and teachers to explore the emerging energy technologies that could become the future of our electrical supply system. In Part 1 of Green Electricity: 25 Green Technologies That Will Electrify Your Future, the author describes the amazing patchwork of 1,300 power plants and over 5 million miles of wire that comprise our national grid and reveals the environmental damages it produces. Part 2 examines the 25 leading ecofriendly contenders to modernize and replace our current grid, describing each proposed technology and how it works. Other relevant information is also provided, such as a qualitative assessment of the pluses, minuses, and limitations of each system, and an assessment of that technology's potential to contribute to our future electrical appetite.
