Book Description
An important aim behind the restructuring of Germany’s and Europe’s electricity systems is to reduce the environmental burden, especially with respect to greenhouse gas emissions, of the current systems. Emissions must be brought down to a level that is sustainable in the long run and consistent with greenhouse gas emission reduction goals. Meeting these goals will require a system (as best as current knowledge suggests) that will be able to cope simultaneously with the fundamental demands for economic efficiency, environmental sustainability and supply security. Making use of existing scenarios, this study sketches such a system. It focuses in particular on auxiliary systems such as energy storage methods and network extensions. The study introduces technologies that can balance electricity in energy systems and that can serve as enabling technologies for the integration of large quantities of renewable energies in the power supply system. It begins with a discussion of normative aims for the future electricity system before continuing with a description of current policies and political developments and an overview of relevant existing energy system studies. These sections serve as background for the remainder of the study. They are followed by discussion and analysis of the growing demand for means to balance the fluctuations found in electricity generated in power systems with a high penetration of renewable energies, the potentials of diverse technologies, requirements for electrical networks, economic impacts and important legal issues. Finally, the main challenges to the achievement of developing balancing technologies and processes for renewable electricity-dominant systems are summarised and recommendations made.

Book Description
The global crisis of 2008-09 has brought to the forefront a plethora of economic and political policy issues. There is a re-opening of discussion on basic economic concepts, appropriate framework for analysis, role of private and public sectors in the economy, structural transformation of economies, human development and managing of growing risks and crises. The purpose of this book has been to bring home the inter-linkages in various parts of the economy and the need for practical policy making to reach development goals while being aware of the instabilities, complexities and downside risks inherent in the nature of a an economy operating in a globalized world. Thematically, this book focuses on two core types of policy: policies that promote strong, sustainable and inclusive growth in low income and middle income developing countries and new and emerging policies that necessitates a discussion amongst policy makers and practitioners. Throughout the book, the authors provide insight in to the different types of policy approaches that can be taken to help the economy grow. Ultimately the book looks to foster discussion amongst policy makers on growth and development.

Book Description
The technical application of screen and stencil printing has been state of the art for decades. As part of the subtractive production process of printed circuit boards, for instance, screen and stencil printing play an important role. With the end of the 20th century, another field has opened up with organic electronics. Since then, more and more functional layers have been produced using printing methods. Printed electronics devices offer properties that give almost every freedom to the creativity of product development. Flexibility, low weight, use of non-toxic materials, simple disposal and an enormous number of units due to the production process are some of the prominent keywords associated with this field. Screen printing is a widely used process in printed electronics, as this process is very flexible with regard to the materials that can be used. In addition, a minimum resolution of approximately 30 µm is sufficiently high. The ink film thickness, which can be controlled over a wide range, is an extremely important advantage of the process. Depending on the viscosity, layer thicknesses of several hundred nanometres up to several hundred micrometres can be realised. The conversion and storage of energy became an increasingly important topic in recent years. Since regenerative energy sources, such as photovoltaics or wind energy, often supply energy intermittently, appropriate storage systems must be available. This applies to large installations for the power supply of society, but also in the context of autarkic sensors, such as those used in the Internet of Things or domestic/industrial automation. A combination of micro-energy converters and energy storage devices is an adequate concept for providing energy for such applications. In this thesis the above mentioned keywords are addressed and the feasibility of printed thermoelectric energy converters and supercapacitors as energy storage devices are investigated. The efficiency of thermoelectric generators (TEG) is low, but in industrial environments, for example, a large amount of unused low temperature heat energy can be found. If the production costs of TEGs are low, conversion of this unused heat energy can contribute to increasing system efficiency. Additionally, printing of supercapacitor energy storage devices increases the usability of the TEG. It is appropriate to use both components as complementary parts in an energy system. Den tekniska tillämpningen av skärm- och stencilutskrift har varit toppmoderna i årtionden. Som en del av den subtraktiva produktionsprocessen av tryckta kretskort spelar exempelvis skärm- och stencilutskrift en viktig roll. I slutet av 1900-talet har ett annat fält öppnat med organisk elektronik. Sedan dess har allt fler funktionella lager producerats med hjälp av tryckmetoder. Tryckta elektronikanordningar erbjuder egenskaper som ger nästan all frihet till kreativiteten i produktutvecklingen. Flexibilitet, låg vikt, användning av giftfria material, enkelt bortskaffande och ett enormt antal enheter på grund av produktionsprocessen är några av de framträdande nyckelord som hör till detta område. Skärmtryck är en allmänt använd process i tryckt elektronik, eftersom processen är mycket flexibel med avseende på material som kan användas. Dessutom är en minsta upplösning på cirka 30 µm tillräckligt bra. Bläckfilmens tjocklek, som kan styras över ett brett område, är en extremt viktig fördel med processen. Beroende på viskositeten kan skikttjockleken på flera hundra nanometer upp till flera hundra mikrometer realiseras. Energikonvertering och lagring har blivit ett allt viktigare ämne de senaste åren. Eftersom regenerativa energikällor, såsom fotovoltaik eller vindkraft, ofta levererar energi intermittent, måste lämpliga lagringssystem vara tillgängliga. Detta gäller stora installationer för samhällets strömförsörjning, men också inom ramen för autarkiska sensorer, som de som används i saker av saker eller inhemsk / industriell automation. En kombination av mikroenergiomvandlare och energilagringsenheter är ett lämpligt koncept för att tillhandahålla energi för sådana applikationer. I denna avhandling behandlas ovan nämnda nyckelord. Genomförbarhet av tryckta termoelektriska energiomvandlare och superkapacitorer som energilagringsenheter undersöks. Effektiviteten hos termoelektriska generatorer (TEG) är låg, men i industriella miljöer kan exempelvis en stor mängd oanvänd låg temperatur värmeenergi hittas. Om produktionskostnaderna för TEG är låga kan konvertering av denna oanvända värmeenergi bidra till ökad systemeffektivitet. Dessutom ökar utskrift av superkapacitorer användbarheten hos TEG. Det är lämpligt att använda båda komponenterna.
