83:T5d3,Förnybar energi är ett område i snabb utveckling, inom EU finns målet 27 % förnybar energi år 2030, vilket innebär en fördubbling från 2012. I världen har den årliga ökningen varit mer än 20 % åren 2004–2014 för solceller och vindkraft. Utvecklingen är driven av klimatfrågan, där övergång till förnybar energi ger en minskning av klimatgaserna. Den starka efterfrågan har gett en kraftig industriell och ekonomisk tillväxt. Globalt räknar man med att 6,5 miljoner arbetstillfällen hade skapats fram till 2014, de flesta inom solenergi, bioenergi och vindkraft. Förnybar energi är även långsiktigt hållbar och kan öka tryggheten samt begränsa kostnadsökningarna, när tillgången av ändliga fossila energikällor minskar.

Förnybar energi ger en bred översikt över den teknik som finns för olika förnybara energikällor och vilka möjligheter det finns att uppfylla samhällets mål. Bokens inledande kapitel ger ett historiskt perspektiv på förnybar energi, därefter behandlas följande energislag:
• Vindkraft
• Vattenkraft
• Solvärme
• Solel
• Biodrivmedel
• Geotermisk energi
• Vågkraft
• Tidvattenenergi
• Vätgas
• Bioenergi
Boken är avsedd för högskolestudier i energi- och miljöteknik. Den riktar sig även till professionella aktörer inom energi- och samhällssektorn, fördjupningsarbeten på gymnasiet samt den intresserade allmänheten.
84:T61d,Small-Scale Renewable Energy Systems: Independent Electricity for Community, Business, and Home explores the ongoing revolution in small-scale energy solutions that enable environmental sustainability, supply resilience, and energy independence. It introduces readers to diverse renewable energy sources, energy storage technologies, and smart consumption strategies – with particular focus on designing systems that operate independently from the conventional power grid. Readers will discover how to effectively combine multiple energy sources into hybrid systems, optimize system architecture for different scales of implementation, and apply smart controls – including open-source solutions – to maximize efficiency. This book serves as an essential resource for students in renewable energy programs at both bachelor's and master's levels, as well as for companies and individuals looking to develop or expand sustainable energy initiatives in an increasingly electrified world. Updated throughout and offers new practical case studies. Presents a broad overview of the development of renewable energy technologies and the associated challenges, and focuses on small-scale applications. Features detailed real-world case studies of homes, businesses, and communities that have achieved significant energy independence or are progressing toward this goal. Provides detailed guidance on integrating multiple renewable energy sources, storage solutions, and smart controls to create resilient off-grid systems tailored to specific needs and environments.85:T6dd,

A revolution is ongoing in the field of small-scale energy solutions, which can enable lower impact on the environment, more robust supply and self-determination. Solar power and other forms of renewable energy sources, which you can implement to generate your own electricity, are growing quickly. Electromobility is transforming the car industry and transportation systems and can also play a role in your energy system. Electricity can be used much more efficiently than before, for example by using LED light, variable speed motor drives and efficient home appliances. Smart controls are available, sometimes with free open source software. All this opens up tremendous opportunities for energy independence, which is the focus of this book.

The book introduces the reader to a number of renewable energy sources, to different options for storing electricity and to smart use of electricity, particularly in the context of small isolated systems. This is important because many renewable energy sources are weather- and season-dependent and usually require storage and smart control, in order to obtain a system that is completely independent of the electricity grid.

In the book, overall system design is explained, including how to combine different sources in a hybrid system. Different system sizes and architectures are also covered. A number of real cases are described, where homes, businesses and communities have achieved a high level of energy independence or are on their way to achieving it.

This book will prove useful in university education in renewable energy at bachelor and master level, and also for companies and private individuals, who want to start or expand activities in the area of renewable energy.
