This book argues that law has a vital role in shaping the electricity system to enable a more active role for consumers in liberalizsed electricity industries. To do that, this book offers a unique legal perspective of the Netherlands, New Zealand and Colombia to help understand some of the current legal approaches to prosumers and therefore the legal challenges and opportunities facing. Law and regulation have the role of creating a level playing field for emerging participants, such as prosumers, to participate and compete in the market together with traditional actors, bringing not only more competition but also representing a more sustainable, environmental and democratic way to supply energy. Furthermore, law and regulation have the role of responding to innovation and creating space for technological advances to procure the changes in the industry without delay.This book examines some of the legal barriers for the raise of energy prosumers. The traditional role of the distributor when responding to increasing distributed generation in the network; prosumers unable to decide to whom they can sell their electricity to; the price of the energy or even whether to participate more actively in demand response programs. A further issue is the lack of clarity about whether small prosumers are entitled to consumer protection rights and legal challenges regarding configuration, access to the network, access to markets and strict unbundling rules for community energy projects. This book provides a clear, analytical, and informed approach to understanding the regulatory framework around energy prosumers. It will appeal to policy makers, lawyers, individuals, business entrepreneurs or communities wanting to engage in energy projects, as well as academics, researchers and students

Transportation electrification, particularly using electric vehicles (EV), has been widely suggested to mitigate global warming and energy security issues due to their economic and environmental benefits. Environmentalists are advertising EV use, and governments are implementing financial incentives to expedite the transition from conventional vehicles to electric ones to achieve energy security and climate change mitigation goals. At the same time, EVs are becoming more affordable as their battery prices decrease. It has been predicted that EV sales will soon surpass gasoline and diesel vehicle sales.

Water screw conveyors have been in use for centuries. Their invention is attributed to Archimedes. However, the idea of using this Archimedean screw also as a hydropower screw to convert hydraulic energy into electrical energy did not emerge until the 1990s. More recently, hydropower screws have been used very frequently at hydropower sites and have now also attracted increasing interest from scientists and users worldwide. This is due to the machine's very good efficiency, it's simple and inexpensive design, and its fish compatibility.This book provides calculation fundamentals for hydropower screws. The author focuses on the description of the hydraulic processes and gives a design flow that can be used to design hydropower screws. The hydraulic behavior, dimensions, speed, efficiency, forces acting on the screw such as sag or lift, as well as the arrangement of the gearbox and the choice of generator are discussed. The theoretical equations, some of which are newly derived, are applied using examples. Finally, a design flow is given that can be used to easily adapt an optimally designed hydropower screw to a location. New findings presented in various scientific publications have been incorporated into the translation of the second German edition. In addition, experiments were carried out at different locations, which led to a better understanding of the available data basis. This has allowed the theoretical predictions of this book to be confirmed experimentally. In addition, the author has investigated a number of faulty installations and has been involved in the design of successful working waterpower plants equipped with hydropower screws.

This book focuses specifically on policy mixes and wind power diffusion in four Nordic countries ¿ Denmark, Finland, Norway and Sweden. Although these Nordic welfare states have much in common, they have adopted different wind power policies and experienced dissimilar diffusion trajectories. Understanding these patterns across the Nordic countries is the central puzzle that this book investigates. Empirically, this book provides a first-of-its-kind comparative study of wind power policies in the Nordic countries. Analytically, the authors contribute to the transition policy mix literature, which remains largely insensitive to political feasibility. This book will be of interest to researchers and students as well as private and public decision makers looking for tools to enable the energy transition.
