In a decentralised system, energy-producing facilities are located closer to the location of energy consumption. A Decentralized Energy system decreases the need for fossil fuels, boosts eco-efficiency, and enables the best possible use of renewable energy sources and combined heat and power. The world is moving closer to achieving Sustainable Development Goals, yet many countries in the developing world continue to face mounting power challenges resulting in constant load-shedding. This is despite the fact that energy efficiency is on the verge of advancing and renewable energy is making significant progress in the electricity industry. This study seeks to determine the role and significance of a transition to a Decentralized Energy system in achieving sustainable development goal number 7. The study found that Decentralized Energy system provides a plethora of benefits to communities, for instance, local communities under decentralised energy system have an alternative that is less expensive than the centralized national grid, and they can assist generate employment opportunities in the community. The paper concludes that even though microgrids powered by renewable energy have significantly increased access to clean energy in developing world, maintaining the microgrids' capacity to operate sustainably remains a challenge.  

The research purpose was to investigate factors that affect Sales of International Solar Mini-Grids in Tanzania Mainland. The motivation for the study was because there was evidence of a decline in sales of International Solar Mini-Grids in Mwanza, Dar es Salaam, and Arusha regions. The study used a sample size of 70 respondents, a cross-section survey, primary data, and secondary data. The study used the mixed methods research design. Multiple linear regression was employed in quantitative data analysis with the aid of SPSS.  Thematic analysis was conducted to derive themes from the qualitative data and information obtained was utilized to supplement the quantitative data. The study revealed that government policies, more specifically energy policy, significantly affect sales of International Solar Mini-Grids in Tanzania Mainland. In addition, the regulatory framework, particularly tariff, significantly affects sales of International Solar Mini-Grids. Also, customers’ purchasing tendencies were significantly affecting the sales of International Solar Mini-Grids. The findings imply that ignoring the factors affecting sales of International Solar Mini-Grids in Tanzania Mainland might worsen the power sector and solar Mini-Grids sustainability. This work recommends that to foster the sales of International Solar Mini-Grids, the government should have a suitable energy policy and regulatory framework geared to enhance the marketability of electricity and enhance customer purchase. The study contributes to knowledge by offering empirical evidence on renewable energy that will be of paramount importance to other renewable energy stakeholders.

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.
