Designing sustainable energy for all : sustainable product-service system design applied to distributed renewable energy
This open access book addresses the issue of diffusing sustainable energy access in low- and middle-income contexts. Access to energy is one of the greatest challenges for many people living in low- income and developing contexts, as around 1.4 billion people lack access to electricity. Distributed Renewable Energy systems (DRE) are considered a promising approach to address this challenge and provide energy access to all. However, even if promising, the implementation of DRE systems is not always straightforward. The book analyses, discusses and classifies the promising Sustainable Product-Service System (S.PSS) business models to deliver Distributed Renewable Energy systems in an effective, efficient and sustainable way. Its message is supported with cases studies and examples, discussing the economic, environmental and socioethical benefits as well as its limitations and barriers to its implementation. An innovative design approach is proposed and a set of design tools are supplied, enabling readers to create and develop Sustainable Product-Service System (S.PSS) solutions to deliver Distributed Renewable Energy systems. Practical applications of the book's design approach and tools by companies and practitioners are discussed and the book will be of interest to readers in design, industry, governmental institution, NGOs as well as researchers.

Data-driven next-generation smart grid towards sustainable energy evolution: techniques and technology review
Meteorological changes urge engineering communities to look for sustainable and clean energy technologies to keep the environment safe by reducing CO
2
emissions. The structure of these technologies relies on the deep integration of advanced data-driven techniques which can ensure efficient energy generation, transmission, and distribution. After conducting thorough research for more than a decade, the concept of the smart grid (SG) has emerged, and its practice around the world paves the ways for efficient use of reliable energy technology. However, many developing features evoke keen interest and their improvements can be regarded as the next-generation smart grid (NGSG). Also, to deal with the non-linearity and uncertainty, the emergence of data-driven NGSG technology can become a great initiative to reduce the diverse impact of non-linearity. This paper exhibits the conceptual framework of NGSG by enabling some intelligent technical features to ensure its reliable operation, including intelligent control, agent-based energy conversion, edge computing for energy management, internet of things (IoT) enabled inverter, agent-oriented demand side management, etc. Also, a study on the development of data-driven NGSG is discussed to facilitate the use of emerging data-driven techniques (DDTs) for the sustainable operation of the SG. The prospects of DDTs in the NGSG and their adaptation challenges in real-time are also explored in this paper from various points of view including engineering, technology, et al. Finally, the trends of DDTs towards securing sustainable and clean energy evolution from the NGSG technology in order to keep the environment safe is also studied, while some major future issues are highlighted. This paper can offer extended support for engineers and researchers in the context of data-driven technology and the SG.

Going nuclear : how atomic energy will save the world
\"In this visionary book, Dr. Tim Gregory challenges prevailing narratives around climate change, arguing that the goal of net zero is not simply to replace fossil fuels with renewables, but to power civilisation using sources of energy that do not emit carbon dioxide. He unequivocally shows that only one emissions-free energy source can rise to that challenge: nuclear power. Going Nuclear calls for decarbonisation to be the twenty-first century's Apollo program, illuminating the far-reaching potential of the atom beyond clean energy to advanced medicine, forensics, atomic gardening, and interplanetary exploration. By interweaving scientific optimism, myth-busting data, and ambitious policy, Gregory offers an alternative nuclear future that can meet the shared goal of environmental stewardship and continued human progress\"-- Provided by publisher.

AI-Enabled Energy Policy for a Sustainable Future
The present time is a seminal decade for the transition of the energy sector through the deployment of green energy and the optimization of efficiencies using the power of automation and artificial intelligence (AI), which demands competitive policies to handle multidimensional endeavors via a single platform. The failure of energy policies can have far-reaching socioeconomic consequences when policies do not meet the energy and climate goals throughout the lifecycle of the policy. Such shortcomings are reported to be due to inadequate incentives and poor decision making that needs to promote fairness, equality, equity, and inclusiveness in energy policies and project decision making. The integration of AI in energy sectors poses various challenges that this study aims to analyze through a comprehensive examination of energy policy processes. The study focuses on (1) the decision-making process during the development stage, (2) the implementation management process for the execution stage, (3) the integration of data science, machine learning, and deep learning in energy systems, and (4) the requirements of energy systems in the context of substantiality. Synergistically, an emerging blueprint of policy, data science and AI, engineering practices, management process, business models, and social approaches that provides a multilateral design and implementation reference is propounded. Finally, a novel framework is developed to develop and implement modern energy policies that minimize risks, promote successful implementation, and advance society’s journey towards net zero and carbon neutral objectives.

Sustainable energy is an important and strategic issue to meet the needs of future generations. In order to ensure sustainable energy, action plans should be created and the steps to be taken should be prioritized. In this study, an integrated AHP/ANP methodology with SWOT Analysis TOWS Matrix is applied for strategic analysis. The study is carried out with the 31 participations of internal and external stakeholders for the Yenişehir region in Mersin province of Turkey. Firstly, SWOT Analysis is applied for the region, and then, it is developed with the TOWS matrix, which is the action tool for the items determined by the SWOT analysis. At this stage, 16 Sustainable Energy Action Plan strategies are determined. Finally, the weights for each strategy are calculated separately with the AHP method and the ANP method, and prioritized, and the importance levels of the strategies are determined. After both solutions, the first three strategies that are asked to be given priority in practice are found to be the same. Priority strategies in the study, increasing renewable energy applications in buildings depending on population density (SO1), reducing greenhouse gas emissions with waste management studies (WO5), and maximizing the energy efficiency potential to provide thermal insulation, create energy efficient systems in buildings (SO3) and emerge as priority strategies. The study is a guide for the first steps to be taken by the region for sustainable energy actions and is carried out effectively with integrated systems.
