Malmquist index analysis confirms the lack of substantial technological innovation, which impedes their energy efficiency and productivity gain. Findings show that pure technical efficiency accounts for the annual efficiency obtained in the DEA model, the technological progress in contrast is the source of their energy inefficiency.</p> Adefarati Oloruntoba, Japhet Tomiwa Oladipo ##submission.copyrightStatement## Tue, 10 Sep 2019 00:00:00 +0000 Design of Stand-alone Solar-Wind-Hydro Based Hybrid Power System: Case of Rural Village in Malawi <p>Malawi has current electrification rate of less than 10% for a population of 18 million connected to the grid. The electricity generation company in Malawi (EGENCO) is greatly affected by low water levels making it difficult to satisfy the existing demand of electricity. This makes it difficult for Malawi to extend its National electricity grid. Thus, the aim of the study is to design stand-alone hybrid renewable energy system which is economically and technically feasible with focus on hydropower, wind, solar and battery bank within Dwangwa area. The study area is estimated to have 420 households, commercial and public service load with primary load demand of 5,556.31 kWh/day and peak load of 302.93 kW. River discharge data were collected from ministry of irrigation and water development while solar and wind data were collected from NASA. HOMER modeling tool was used to design a stand-alone system. From simulation results, the best design flow for Dwangwa river is 159 L/s at elevation of 100 metres and the best hybrid system combination was hydropower-wind-solar-battery and converter. The whole hybrid system initial capital cost was $2,662,638 while Net present cost (NPC) and levelized cost of energy (LCOE) were $3,597,197 and $0.134/kWh respectively. However, the cost of electricity in Malawi on the grid is K88.02/kWh ($0.11/kWh) which makes the system expensive. Therefore, the study has shown that the hybrid system is not economically viable. However, Government intervention can help to make the system monetarily acceptable and viable.</p> Sylvester W.

The conceptual framework is based on a pilot study conducted in India and strengthened by a comprehensive review and analysis of relevant literature. Accordingly, the proposed paradigms are a result of best practices identified during the pilot study. The results demonstrate the financial viability of the pilot study conducted over a period of three years. Additionally, the results provide evidence of the impact of the circular economy on economic growth, employment opportunity, and reduction in environmental waste. The discussion also identifies the barriers to the adoption of a circular economy framework including the role of attitude towards the environment and the skill gap in labor.</p> S.
