Ensuring an ongoing supply of power in a low carbon economy is one of the major national and international challenges that almost every country faces. Investments in alternative and renewable energy technologies have risen steadily over the last decade, particularly since the ratification of the 2030 Paris Agreement. Although reasonable progress has been made as a result of this, even the most developed renewable energy technologies, for example, solar, wind and hydro, cannot satisfy the rapidly growing energy demand of the world. Arguably a non-renewable energy source, nuclear energy may be one clean energy answer for the future. More specifically, small-scale nuclear energy holds considerable potential. Such potential exists in the form of light water small modular reactors (LW-SMRs). These SMRs have the capability to meet the energy independence and the energy security needs of many countries while reducing capital and operating expenditure and environmental and physical footprint. The modularity aspect of this technology allows for varied application, from large towns to rural regions that currently rely on individual generators. It also creates the opportunity of cogeneration with already existing conventional power generation technology to diversify power generation and increase grid stability. LW-SMRs are not a new idea; in fact, they have been used to power U.S. aircraft carriers and submarines for almost 60 years. This case study will address the advantages and disadvantages of the LW-SMR, using the market leader NuScale as an example. NuScale in Oregon, United States, is arguably the most experienced and influential LW-SMR nuclear energy company when it comes to the factory fabrication of LW-SMRs.

Different power generation technologies have different advantages and disadvantages. However, if compared to traditional energy sources, renewable energy sources provide a possibility to solve the climate change and economic decarbonization issues that are so relevant today. Therefore, the analysis and evaluation of renewable energy technologies has been receiving increasing attention in the politics of different countries and the scientific literature. The household sector consumes almost one third of all energy produced, thus studies on the evaluation of renewable energy production technologies in households are very important. This article reviews the scientific literature that have used multiple-criteria decision-making (MCDM) methods as a key tool to evaluate renewable energy technologies in households. The findings of the conducted research are categorized according to the objectives pursued and the criteria on which the evaluation was based are discussed. The article also provides an overview and in-depth analysis of MCDM methods and distinguishes the main advantages and disadvantages of using them to evaluate technologies in households.

Large-scale promotion of small scale decentralized renewable energy technologies to achieve a part of millennium development goal remained a great challenge until recently. However, a properly implementation of a public private partnership applied in biogas sector in Nepal has shown that scaling up of small scale renewable energy technologies is feasible if a multi-stakeholder sector development approach and favorable policy as well as modality is adopted. Nepal’s biogas program has been instrumental in helping to achieve some of the Millennium Development Goals (MDGs) by creating economic and social development opportunities in a sustainable way. Such model could also be widely replicated in any other renewable energy technologies and other continent of the world.

There have been many attempts to include citizens as more active players in the proliferation of renewable energy technologies. However, the roles that citizen users play in renewables proliferation are not limited to adoption, but include technological domestication, innovation, and market creation. This chapter first reviews innovation by citizen users in the early phases of small-scale renewable energy technologies (S-RET) technology development in wind turbines, solar collectors, and low-energy housing. It then examines user innovation and peer assistance in the later phases of diffusion in air-source and ground-source heat pumps, pellet-burning systems, and solar collectors. It reviews research user motivations, diffusion pathways, and peer intermediation, and pays particular attention to how the forms of innovative citizen energy communities are changing from locality-based community energy initiatives to distributed and Internet-mediated energy communities. The chapter concludes by drawing policy implications regarding user innovation and peer assistance in the transformation of energy systems.

There is an increasing need for the integration of renewable energy into the energy sector in Egypt. As the electricity subsidies are residing for consumers in Egypt, electricity prices are increasing. This increase in energy prices can be mitigated by the integration of renewable energy technologies. One of the most promising renewable energy technologies that will help stabilize the energy situation in Egypt, is Solar Thermal Energy. Solar Thermal Energy has a great potential in Egypt due to the availability and intensity of direct irradiance in Egypt. Therefore, Egypt has an amazing opportunity as a developing country to start perusing solar thermal technologies; these technologies include decentralized and centralized technologies. Decentralized technologies are targeted more for regular consumers and centralized technologies are targeted more for power generation and industries.


The agrophotovoltaics innovative technology (APV) is a staged culture that combines photovoltaic power generation and agricultural production on the same land. The coexistence of solar panels and crops implies a sharing system of sunshine between these two types of production. It opens new horizons by making drylands cultivable while producing clean energy for local populations. APV lies at the heart of a global energy transformation, increasing world energy demand, negative global warming effects, and global water scarcity, and offers a promising investment to farmers and new opportunities for ecologically sustainable livelihoods. As a renewable energy investment, it meets the sustainability demand by reducing climate concerns but it also opens the door to significant socioeconomic benefits. However, the final outcome of the investment depends on government policies, environmental conditions, technical progress and what materials are used in solar power systems. This paper answers three questions: Why is the agrophotovoltaics an important technology today? What are the advantages and disadvantages of agrophotovoltaics use? And what are the economic risks related to this kind of investments? By analyzing Penthéréaz solar panels power generation example in Switzerland, the research illustrates the success factors to the investment and inherently provides recommendations regarding future investments.

One of the most encouraging sorts of renewable energy is ocean wave energy. In spite of a large number of investigations in this field during the last decade, wave energy technologies are recognised as neither mature nor broadly commercialised compared to other renewable energy technologies. In this paper, we develop and optimise Power Take-off (PTO) configurations of a well-known wave energy converter (WEC) called a point absorber. This WEC is a fully submerged buoy with three tethers, which was proposed and developed by Carnegie Clean Energy Company in Australia. Optimising the WEC’s PTO parameters is a challenging engineering problem due to the high dimensionality and complexity of the search space. This research compares the performance of five state-of-the-art metaheuristics (including Covariance Matrix Adaptation Evolution Strategy, Gray Wolf optimiser, Harris Hawks optimisation, and Grasshopper Optimisation Algorithm) based on the real wave scenario in Sydney sea state. The experimental achievements show that the Multiverse optimisation (MVO) algorithm performs better than the other metaheuristics applied in this work.

Improving energy efficiency is one of the main ways to reduce energy pollution that leads to economic development, increasing energy access and better life. That can result in reducing fossil fuel use and growing clean energy supplies. The Gulf countries have as many renewable resources as hydrocarbons like sunshine, considerable wind resources, and geothermal. The economy of the Middle east deeplydepends on fossil fuel export. Declining fossil fuel supplies and rising energy prices are driving global energy supplies to renewables energies. Although the Middle East region, due to its special geographical features, has significant potential for the growth of renewable energy sources, they have not been developed yet. It overviews the energy situation and sustainability, economic potential of renewable energy, policies for energy systems over the recent decades in six resource-rich countries in the middle east. In addition, along with renewable energy technologies, possible ways to solve current environmental problems are recognized. The methodology of this work is PESTLE analysis of these countries' energy status to develop a long-term mechanism for sustainable and secure energy for the Middle East based on Political, Economic, Social, Technological, Legal, Environmental. Also, it identifies challenges that restrict the development of renewable energy technologies in the Middle East. By analyzing the status of energy in recent decades, the importance of implementation of effective energy policies to develop sustainable energy can be realized. Key words: energy source, sustainable future, renewable, effective policy, resource-rich countries.
