The Paris Agreement on Climate Change adopted on December 12, 2015 is a voluntary effort to reduce greenhouse gas emissions. In order to reach the goals of this agreement, there is a need to generate electricity without greenhouse gas emissions and to electrify transportation. An infrastructure of SPCSs can help accomplish both of these transitions. Globally, expenditures associated with the generation, transmission, and use of electricity are more than one trillion dollars per year. Annual transportation expenditures are also more than one trillion dollars per year. Almost everyone will be impacted by these changes in transportation, solar power generation, and smart grid developments. The benefits of reducing greenhouse gas emissions will differ with location, but all will be impacted. This book is about the benefits associated with adding solar panels to parking lots to generate electricity, reduce greenhouse gas emissions, and provide shade and shelter from rain and snow. The electricity can flow into the power grid or be used to charge electric vehicles (EVs). Solar powered charging stations (SPCSs) are already in many parking lots in many countries of the world. The prices of solar panels have decreased recently, and about 30% of the new U.S. electrical generating capacity in 2015 was from solar energy. More than one million EVs are in service in 2016, and there are significant benefits associated with a convenient charging infrastructure of SPCSs to support transportation with electric vehicles. Solar Powered Charging Infrastructure for Electric Vehicles: A Sustainable Development aims to share information on pathways from our present situation to a world with a more sustainable transportation system with EVs, SPCSs, a modernized smart power grid with energy storage, reduced greenhouse gas emissions, and better urban air quality. Covering 200 million parking spaces with solar panels can generate about 1/4 of the electricity that was generated in 2014 in the United States. Millions of EVs with 20 to 50 kWh of battery storage can help with the transition to wind and solar power generation through owners responding to time-of-use prices. Written for all audiences, high school and college teachers and students, those in industry and government, and those involved in community issues will benefit by learning more about the topics addressed in the book. Those working with electrical power and transportation, who will be in the middle of the transition, will want to learn about all of the challenges and developments that are addressed here.

This book proposes that usage-based charging schemes are essential to generate the incentives necessary for efficient operation of multiservice networks. The rapid development of network technology is enabling sophisticated new services and applications which demand new charging models. The same technology provides the means to operate the right charging schemes.Some of the work done in the European collaborative project CA$hMAN (Charging and Accounting Schemes in Multiservice ATM Networks). This project combined performance and economic models of network resource usage and cutomer utility to construct simple but effective charging schemes which were implemented and trialled in an advanced management platform.
NEW YORK TIMES BESTSELLER • A renowned journalist and legal commentator exposes the unchecked power of the prosecutor as a driving force in America’s mass incarceration crisis—and charts a way out. “An important, thoughtful, and thorough examination of criminal justice in America that speaks directly to how we reduce mass incarceration.”—Bryan Stevenson, author of Just Mercy “This harrowing, often enraging book is a hopeful one, as well, profiling innovative new approaches and the frontline advocates who champion them.”—Matthew Desmond, author of Evicted FINALIST FOR THE LOS ANGELES TIMES BOOK PRIZE • SHORTLISTED FOR THE J. ANTHONY LUKAS BOOK PRIZE • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY NPR • The New York Public Library • Library Journal • Publishers Weekly • Kirkus Reviews The American criminal justice system is supposed to be a contest between two equal adversaries, the prosecution and the defense, with judges ensuring a fair fight. That image of the law does not match the reality in the courtroom, however. Much of the time, it is prosecutors more than judges who control the outcome of a case, from choosing the charge to setting bail to determining the plea bargain. They often decide who goes free and who goes to prison, even who lives and who dies. In Charged, Emily Bazelon reveals how this kind of unchecked power is the underreported cause of enormous injustice—and the missing piece in the mass incarceration puzzle. Charged follows the story of two young people caught up in the criminal justice system: Kevin, a twenty-year-old in Brooklyn who picked up his friend’s gun as the cops burst in and was charged with a serious violent felony, and Noura, a teenage girl in Memphis indicted for the murder of her mother. Bazelon tracks both cases—from arrest and charging to trial and sentencing—and, with her trademark blend of deeply reported narrative, legal analysis, and investigative journalism, illustrates just how criminal prosecutions can go wrong and, more important, why they don’t have to. Bazelon also details the second chances they prosecutors can extend, if they choose, to Kevin and Noura and so many others. She follows a wave of reform-minded D.A.s who have been elected in some of our biggest cities, as well as in rural areas in every region of the country, put in office to do nothing less than reinvent how their job is done. If they succeed, they can point the country toward a different and profoundly better future.
