    An assessment of skills supply and demand for renewable energy, energy efficiency, and regional energy integration
    (University of the Witwatersrand, Johannesburg, 2022) Centre for Researching Education & Labour (REAL); University of the Witwatersrand, Johannesburg
    The SADC region relies heavily on energy produced from coal and water and has grappled with an energy crisis over the years, seen through insufficient and inefficient energy supply. This crisis is mostly a result of a changing climate, including droughts, outdated infrastructure, and the depletion of natural resources. These natural resources include coal and gas, and their use for power generation further contributes to climate change, who’s impacts are being faced globally. There has therefore been a desire and a call to shift towards renewable energy (RE) in the SADC region, which has the resources and conditions to make this shift. This is driven by the SADC Protocol on Energy and the various national policies. The SADC Protocol on Energy (SADC 20) identifies a number of strategic plans over the last 10 years which build on previous policies. These include “the Regional Energy Access Strategy and Action Plan 2020 to 2030 (SADC, 2020), the Renewable Energy and Energy Efficiency Strategy and Action Plan 2016 to 2030 (SADC, 2016), the SADC Industrial Energy Efficiency Programme and the development of the Regional Gas Master Plan” (SADC, 1996). Implementation has occurred at different rates in the various member states, and the 2018 SADC Renewable Energy and Energy Efficiency Status Report states that “Since 2015, SADC Member States have greatly increased their commitment to renewable energy and energy efficiency, including important innovations to stimulate mini-grids and distributed renewable energy” (SADC, 2018). This is also the case in regional integration as per the SADC Regional Indicative Strategic Development Plan (RISDP) 2020–2030 (SADC 2020) and through the Southern African Power Pool (SAPP) and its regional electricity plans, trading platforms, and policy and regulatory alignment initiatives (SAPP, 2017) together with the SADC Regional Electricity Regulatory Association (RERA, 2022). This transition to RE, however, needs to be just, thereby ensuring that the current workforce is protected and that the skills ecosystem is prepared not only to respond to current demands but those required to transition to a more just and resilient energy system.

    Antecedents of attitudes towards the use of environmentally friendly household applicance products in Zimbabwe An extension of the theory of planned behaviour
    (Emerald Publishing Limited, 2023) Maziriri, E.T.; Nyagadza, Brighton; Chuchu, Tinashe; Mazuruse, Gideon
    Purpose– This study aims to determine the antecedents that influence attitudes towards the use of environmentally friendly household appliance products and consumers’ green purchase intention among consumers in Harare, Zimbabwe. Design/methodology/approach– Data were collected from 329 consumers in Harare, Zimbabwe’s commercial capital who were served fromfive using a structured questionnaire via an online web-based crosssectional survey. Hypothesised relationships were tested throughstructural equation modellingwith the aid of Smart PLS software. Findings– Green product awareness, social influence, perceived benefit and attitude towards green appliances were found to have a significant positive effect on green purchase intention. Research limitations/implications– The study’s findings may not be generalised to other contexts as sample data was only collected in Zimbabwe. Complementary cross-sectional research studies can be done in other parts of the world to enable cross-cultural comparisons and methodological validations.

    Comparing occupant satisfaction in Green versus Conventional Residential Real Estate in South Africa
    (Proceedings of the AfRES 2024 Conference, 2024-09) Masotya, Adam; Simbanegavi, Prisca; Weaich, Malcolm; Adewunmi, Yewande; Ndlovu, Pride; Gethe, Faranani
    This study compares occupant satisfaction in green versus conventional residential real estate in South Africa. It investigates the benefits and satisfaction levels related to green developments, particularly in terms of energy savings and socio-economic Impacts. The research aimed to determine if there is a significant difference in occupant satisfaction between green and conventional residential developments. A quantitative approach was employed, utilizing stratified random sampling to survey 160 occupants from two developments: Crossberry Central (green) and Little Manhattan (conventional). Data was analysed using the Mann-Whitney U and Wilcoxon W tests due to non- normal data distribution. The findings indicate that occupants of green developments report significantly higher satisfaction levels. Key areas of satisfaction include air quality, utility savings, and environmental benefits. Green developments demonstrate higher levels of satisfaction regarding reduced utility bills, improved indoor air quality, and contributions to environmental conservation. The study concludes that green residential developments significantly enhance occupant satisfaction compared to conventional housing. This suggests a socio-cultural shift towards valuing sustainable living environments, emphasising the importance of promoting green building practices to improve both environmental and occupant well-being.
