The significance of SMMEs in local government is closely associated with job creation and income generation; SMMEs subscribe to the stimulation of socioeconomics in South Africa. The main aim of the study was to investigate the challenges affecting the implementation of renewable energy on Small, Medium, and Micro Enterprises in South African Local Government. The study was conducted at Raymond Mhlaba Local Municipality in Alice and municipal officials and SMME owners taking part as participants within the same area. The study followed an interpretive philosophy with a case study research design. The sample size was 12 participants, using a non-probability sampling method and purposive sampling technique. The study's target population included SMME owners and municipal officials from the Directorate of Engineering and Services from Raymond Mhlaba Local Municipality. The study collected primary data using semi-structured interviews. Thematic Data Analysis was used to analyze the data. The study findings revealed financial barriers, lack of technical expertise, and the challenge of permits and approvals to connect renewable energy systems to the grid as the main challenges affecting the implementation of renewable energy for SMMEs.  The study's recommendations include financial incentives through grants, capacity-building workshops, collaboration with various stakeholders, and community solar projects. The contribution of this study will be significant since most SMMEs struggle with electricity supply during load shedding, which negatively affects business production and operations.

Energy is one of the most important resources in the growth of an economy. The generation of power is key to the effectiveness of sustainable energy management. Energy production warrants production hence connected to economic development. Environmental change has an impact on the sustainability of renewable energy. The objective of this study was to analyze the effect of environmental change on sustainable energy in Olkaria Geothermal and Kenya Power Station, Nakuru County, Kenya. The study was informed by two theories namely; Socio-technical Transitions Approach Theory and Co-evolutionary Approach to Transitions. The study adopted a descriptive research design. The target population was 359 employees with a stratified sample design. The sample frame was 108 employees being 30% of the total population. Data were analyzed using the Statistical Package for Social Science (SPSS). The preliminary data was analyzed using descriptive statistics and presented in the form of tables. Inferential statistics were employed through Pearson’s Correlation analysis and regression analysis was used to test the study hypothesis at a 5% significance level.  The findings indicated that was a statistically significant relationship between environmental change and sustainable energy (r=0.286; p=0.005). Further, the study revealed that environmental change has a statistically significant effect on sustainable energy in Olkaria Geothermal and Kenya Power Station, Nakuru County, Kenya (p<0.05). The study recommends that institutional environmental changes should be examined and their influence on sustainable energy management.
