Abstract: The United Nations Sustainable Development Goal (SDG) 7 of ensuring access to affordable, reliable, sustainable, and modern energy for all is of critical importance to the development and growth of South Africa's economy. The ambition in SDG 7 is that by 2030 there should be universal access to affordable, reliable, and modern energy services. Electricity as energy is an essential enabler of economic development that can lift people out of poverty, therefore supporting sustainable development and industrialization. Improved access to energy in South Africa has the potential to alleviate poverty, promote industrialization and economic development. However, challenges with the state-owned energy utility company, Eskom, have resulted in the country experiencing regular power cuts. This article aims to provide a substantial review of the current renewable energy scenario in South Africa considering the faced challenges and their potential solutions for sustainable development. It will also highlight some of the progress on SDG7 integration, strategies, and innovations in support to expedite South Africa progress towards universal energy access. The discussion serves as a guide to further investigate the development of renewable energy projects and the barriers to the implementation.

Authors: Kumba, Hagreaves; Oludolapo Olanrewaju Abstract: The information, communication, and technology (ICT) are two interconnected topics that are crucial in today's digital age. In today's world ICT has become an essential tool for communication, education, and economic growth. Access to the internet has become a basic human right, with more than half of the world's population using it, and infrastructure development is critical for providing this access, particularly in Africa. In today's modern world, the internet is a vital tool for communication, education, and economic growth. This paper explores internet access and infrastructure development in Africa, to identify the impacts, challenges, and solutions for improving access. An extensive literature review is done which will assist in identifying and addressing key issues related to internet access and infrastructure development, as well as providing insights into how to maximize the benefits of these technologies for individuals and communities.

The textile manufacturing industry in Southern African countries relies mainly on conventional manufacturing techniques. Efforts to adopt emerging technologies in production processes have shown promising results. Currently, the textile industries face problems with international market penetration, high production costs, and minimal digitalisation. This is compounded by the inadequate availability of local skills to effectively maintain emerging technologies manufacturing equipment. In this study, secondary data was employed through existing research on textile manufacturing to explore the current state of digital technology adoption and its impact on the textile industry. The comparative analysis of best practices unlocked opportunities to improve productivity, efficiency, and competitiveness, as well as identify skills gaps and training needs. Further work was needed to assess and comply with environmental requirements associated with the use of emerging technologies in textile industries.

The system, simulated using PVSyst software, aims to fulfill the university's increasing energy demands while prioritizing sustainability and reducing reliance on conventional energy sources. The study examines system deployment’s energy production potential, return on investment, and CO2 emissions reduction. The designed system has a performance ratio of 83.87%, indicating efficiency through the annual generation of 1834.21 kWh/kWp at an investment return of 292% with a net CO2 emissions reduction potential of 33, 22.5 tCO2 within its 30-year life. The study provides valuable insights into integrating renewable energy solutions within educational institutions and promotes collaboration among governmental bodies, investors, and the community to establish an effective PV system that aligns with the university's vision.
