A wide variety of sustainable natural energy resources are available, but they require technical solutions for their implementation. The general trend in energy research is based on renewable resources, amongst which solar energy stands out, being the most mature and widely accepted. In this paper, the current state of the sustainable energy system has been analysed. The main purpose is to provide additional context to assess future scenarios. The study of past contributions allows sustainability planning and increasing the welfare of future society. The aim is to highlight global trends in research on sustainable solar energy from 1995 to 2020 through a bibliometric analysis of 4260 publications. According to their linkages, the analysed articles are distributed in nine clusters: Sustainability assessment, Sustainable energy solutions, Environmental payback time analysis, Sustainability of solar energy in different scenarios, Environmental sustainability, Solar energy applications, Sustainable energy optimisation, Energy transition and Energy and sustainable scenarios. The most repeated keywords are Sustainability, Renewable energy, and Solar energy. Energy research and the exploration of new renewable solar resources are still necessary to meet sustainable energy’s future challenges.

The present utilization of fossil fuels has a substantial influence on the escalation of greenhouse gas (GHG) emissions. Renewable energy is crucial in mitigating greenhouse gas emissions, which in turn helps minimize the effects of extreme weather and climate change. Additionally, it ensures a dependable, prompt, and economically viable energy supply. Due to its large size and abundant natural resources, Indonesia has experienced a growing need for renewable energy, which has been driven by increased consumption. Indonesia has successfully shifted towards renewable energy by implementing energy policies and plans and by progressively increasing the proportion of renewable energy in its overall energy mix. The target is to achieve a renewable energy mix from 11% in 2021 to 23% in 2025 and 31% in 2050. The proportion of the industrial sector has been steadily rising and currently stands at 37%, which represents a significant increase of 6% since 2015. Meanwhile, the services sector accounted for 22% of the overall share in 2022. The electrification rate of households has significantly increased from 86% in 2000 to 99.6% in 2022. The original target of achieving 100% was postponed from 2020 to 2022 and has yet to be accomplished. The primary objective of this chapter is to conduct an in-depth examination of the present condition, energy usage and GHG emission, energy policy and future potential, and data regarding Indonesia’s renewable and sustainable energy resources.

Renewable energy is a sustainable and green energy converted from renewable energy resources in the nature. There is a huge amount of renewable energy resources in the ocean that can be changed into useful energy like electricity, store for long time use, or apply in the daily energy consumption. These marine renewable energies (MRE) include wave energy, ocean thermal energy, tidal energy, ocean current energy, salinity gradient energy, and offshore energy. With a big area, the oceans have been prospected that it brings endless renewable energy sources for social development and human demand. The renewable ocean energy shows many advantages of sustainable energy, clean energy, and non-carbon dioxide emissions by generating from wave and water in the ocean with an enormous amount of natural energy resources. The MRE can service at many areas of off-shore, on-shore, and remote areas where need energy to drive daily living demands. The MRE reveals some disadvantages such as the influence of daily, monthly, season, and period of time. The solutions have been developed to solve the limitations of the MRE such as developing the storage method to store energy for long time use or making the balance of the output performance to improve quality of the renewable energy. The MRE has also received many concerns from countries by promulgating policies, strategies, and plans to develop the renewable ocean energy such as green economy development, blue economy strategy, carbon dioxide emission reduction, and encouragement of using marine renewable energy. This paper reviews current marine renewable energy with its generation, storage, and application. The work also mentioned some advantages, disadvantage, policies, strategies, and solutions to encourage the development of the renewable ocean energy in over the world. The results hope that it will be spread development, exploitation, and application of marine renewable energy in the near future.

Energy production, consumption, policies and recent developments in Turkey

<p>At COP26, Vietnam committed to achieve net zero emissions by 2050. Up to now, several strategic policies and master plans concerning energy and power development along with emission reduction have been introduced. The national power development plan for the 2021–2030 vision to 2050 (PDP8) has directed for gas-to-hydrogen fuel conversion at gas turbine power sources in the national power system when the technology is commercialized and the cost is appropriate. Therefore, gas turbine power plants (GTPPs) with a total capacity of approximately 32.4 GW by 2050, using domestic natural gas and imported liquefied natural gas (LNG), will be expected to switch to using green hydrogen (GH2) to cut greenhouse gas (GHGs) emissions. This study uses the SWOT analysis and analytic hierarchy process (AHP) method to quantitatively analyze and examine the factors influencing the perspective of GH2 conversion at CTPPs in Vietnam. Research results show that among the four groups of Strengths, Weaknesses, Opportunities, and Threats being examined, the most influencing one is Weaknesses with the highest weight of 0.381, followed by Threats (0.343), suggesting that the GH2 conversion ambition will be facing significant challenges and difficulties. At the level of element factors in the groups, the lack of infrastructure and insufficient legal framework/specific incentive mechanisms are the biggest weaknesses, with weights of 0.362 and 0.326, respectively, while the consistent policies of the state and abundant potential of renewable energy resources, weighing 0.446 and 0.235, respectively, are Vietnam's prominent strengths. Additionally, remarkable opportunities include the effective exploitation of available renewable energy resources (0.338) and great contribution to reducing emissions (0.288), while the main challenges remain the lack of capital (0.471) and high GH2 cost (0.284). The research results clarify the typical problems of a developing country like Vietnam in the global energy transition trend toward carbon neutrality: high potential of renewable energy sources, great political determination, and ambitious goals for green growth, but significant difficulties and challenges due to the low starting point and limited technological and financial resources while energy demand is constantly increasing. Thus, some strategic solutions are proposed, including taking advantage of internal strengths to avoid/limit external threats, making the most of strengths to exploit opportunities, and minimizing weaknesses to take advantage of opportunities and to limit the threats.</p>

In this article, we provide a brief overview of solar photovoltaic and thermal energy, wind turbines with vertical and horizontal axes, and other sustainable energy production systems as well as energy storage systems. In some remote areas away from easy access to electricity and fresh water, a self-contained and self-sustainable off-grid energy production and storage farm is very much needed. In this so-called sustainable energy farm, solar photovoltaic and solar thermal energies along with wind energy can be harvested and stored in a secured battery warehouse with mobile wireless surveillance systems with unpredictable coherent motions. In this battery-based energy storage system, special fire protection measures must also be employed with heat sensors and early detection and alarm systems. The alarm system will be connected to both local fire stations and automated fire extinguishing systems. A subsequent paper will present the details of this wireless fireproof alarm powered by sustainable energy resources. The main purpose of this paper is to document, provide references, and inform about the state-of-the-art achievements in the field of renewable energies, particularly, solar, wind, and other green energy resources.

Promoting green energy initiatives are vital in educational institutes to encounter the energy demand and providing a sustainable life. In the most part, solar and wind energy options are chosen as renewable energy projects to meet part of electricity demand. However, because of the intermittent nature of these sources, alternative technologies should be chosen to provide effective and sustainable solutions. Various energy resources need to be combined in order to provide effective and efficient power generation. The present paper therefore focuses on the feasibility study of integrated energy systems for the energy supply of the educational institution. The work examines the techno-economic performance of various grid-connected and stand-alone integrated energy systems for an educational institute for making a decision before implementing green energy technologies. First, the energy demand is estimated for the entire campus. Further, the potential of renewable energy resources is assessed using NASA and NREL. A detailed survey was carried out to select the components required to model the various integrated energy systems. The modelling, optimization and economic study are performed using HOMER Pro software. A comparative economic analysis is made among considered integrated systems using Net Present Cost (NPC), COE and pay-back period. The study divulges that the grid-connected hybrid system is the optimal one for meeting the power demand of the institute in a reliable manner.

Evaluation of energy alternatives for sustainable development of energy sector in India: An integrated Shannon’s entropy fuzzy multi-criteria decision approach

Growth of industry and reliance on nonrenewable forms of energy in the SAARC region have added to the problem of environmental degradation, which has also increased the costs of health and exposure to climate change. The shift to renewable energy, technological change and sustainable tourism is necessary to secure the economic well-being, preserve the natural resources and guarantee the safety of people. This article examines how green energy is correlated with technological innovation, tourism and sustainability in the SAARC countries between the year 2000 and 2023 using the ARDL estimation methodology in the STIRPAT model. The independent variables are the consumption of renewable and nonrenewable energy, industrial production, foreign direct investment, technological advancement, tourism, participation of the labor force and urbanization. The dependent variables have been the environmental degradation, economic growth and population health. Model 1 (Environmental Sustainability Model) results show that the renewable energy, foreign direct investment, tourism and technological innovation lessen environmental degradation, whereas industrial activity and use of fossil fuels aggravate the situation. Model 2 (Economic Sustainability Model) indicates that long-term economic growth is influenced by renewable energy, innovation, tourism and labor force participation, but non-renewable energy is positive in the short term. According to Model 3 (Social Sustainability Model), the development of renewable energy, technological advances and tourism have a beneficial impact on the population's health in contrast to industrialization and fossil fuels. The paper identifies the necessity of the SAARC economies to speed up the process of switching to renewable energy, enhance the innovation potential and incorporate sustainable tourism in national policy. It is based on the 3Ps theory (People, Planet, Profit) and highlights the importance of clean energy and technology as the key solution to the balance in the environment, social welfare, and economic stability of the region.
