Human activities in recent years with the excessive emission of greenhouse gases have had a negative impact on increasing global temperatures. In this regard, one of the best ways to control it is to move toward sustainability with more use of renewable energy. Therefore, this study aims to assess the indicators of sustainable energy, explore benefits of sustainable energy and evaluate strategies to enhance energy sustainability in line with Sustainable Development Goal (SDG) 7.

Quantitative research strategy was adopted. Questionnaires were developed and administered through convenience and snowball sampling techniques to professionals in the energy sector. Data collected was validated by using Cronbach’s alpha coefficient and discriminant validity, whereas objectives were analyzed by using the relative importance index, mean score ranking and Kruskal–Wallis test.

From the findings, the significant indicators of sustainable energy were as follows: reduction in greenhouse gas emissions from energy production, use of renewable energies and policies on proper utilization of energy resources. Furthermore, a reduction in greenhouse gas emissions, less harm caused to the environment and an increase in the economic and social development process were the major benefits of sustainable energy. Finally, the findings of the study revealed that a strong and accounted policy program, adopting sustainable energy indicators and strategic communication are the significant strategies needed to be put in place to enhance energy sustainability.

The study serves as a reminder to policymakers of the crucial role they have to play in enhancing energy sustainability by putting in place suitable policy programs and methods.

The originality of this study is that it is arguably a pioneering study in Ghana and contributes to the body of knowledge on energy sustainability.

Since 2010, the eastern Mediterranean has witnessed a transformative narrative with the discovery of natural gas reserves off the coasts of Cyprus and Israel. This pivotal development has drawn attention to the region, where Egypt, Israel, Cyprus, Turkey, and Greece share maritime borders. The emergence of natural gas has reshaped geopolitical dynamics, and Western countries assume to reduce their reliance on Russia for energy supplies. This chapter explores the magnitude of natural gas discoveries and production in Cyprus and Israel, examining the interconnection of their fields and the ambitious endeavor of laying a 1,900-km underwater pipeline to the Greek island of Crete. Additionally, it highlights the pivotal roles played by key regional actors such as Israel, Turkey, and Egypt in shaping security and energy negotiations. However, Turkey has a significant position in the eastern Mediterranean and the Middle East, but tensions have arisen as neighboring countries seek to limit Turkey’s involvement in regional energy discussions, viewing its policies as a potential threat, thereby exacerbating Turkey’s regional interventions, particularly in Cyprus. Each of these countries in the Middle East is struggling to get more of the cake. Above all, Israel has been a gas importer throughout its history and now dreams of becoming a natural gas exporter to Europe.

The purpose of this study is to investigate the influence of varying concentrations of nano-SiO₂ particle doping on the structure and properties of the micro-arc oxidation (MAO) coating of 7075 aluminum alloy. This research aims to provide novel insights and methodologies for the surface treatment and protection of 7075 aluminum alloy.

The surface morphology of the MAO coating was characterized using scanning electron microscope. Energy spectrometer was used to characterize the elemental content and distribution on the surface and cross section of the MAO coating. The phase composition of the MAO coating was characterized using X-ray diffractometer. The corrosion resistance of the MAO coating was characterized using an electrochemical workstation.

The results showed that when the addition of nano-SiO₂ particles is 3 g/L, the corrosion resistance is optimal.

This study investigated the influence of different concentrations of nano-SiO₂ particles on the structure and properties of the MAO coating of 7075 aluminum alloy.
