    Abstract The COVID-19 pandemic is having an unprecedented impact on social, economic, and political situations of all countries around the world with no sight to its end. Business sectors such as solar distributors, which have been instrumental in supporting the governments' ambitious universal electrification programs, have been negatively affected by the pandemic. The main aim of this paper is therefore to explore and conduct a comparative assessment before and during the COVID-19 pandemic of the key challenges of solar-based businesses in Ethiopia focusing on the distributors and installers and to provide policy recommendations. Qualitative and quantitative assessments were employed during this study. The results show that before the pandemic, finding a skilled workforce, gaining a technical knowledge of the technology, competing in the market, and lack of consumer awareness and initial investment were the key challenges. The importation of solar technologies has been halted by the arrival of the COVID-19 exacerbating existing challenges and threatening the very existence of the businesses. The impact of the pandemic on income levels of end-users of solar technologies, together with the lack of sufficient supply of technologies to the businesses, most of the businesses are forced to lay off their employees deepening the unemployment rate and, in some cases, forcing businesses to be closed. These circumstances affect economic development and dents the progress made so far in facilitating energy access to remote communities. To protect these vulnerable but very essential small businesses, necessary interventions are recommended. This article is categorized under:Photovoltaics > Economics and Policy.

    Abstract As the COVID-19 pandemic gains ground in the African continent, it will create havoc and unprecedented health and economic crisis. The crisis has exposed the robustness and resilience of the economies and services such as health systems around the world and it is disaster in the making while the pandemic is spreading fast to the African continent. This is alarming mainly because the continent has weak health system compounded by low access to modern and reliable electricity. It is also anticipated that the crisis will be brought ample opportunities and the African governments and the people should make coordinated and concerted effort in developing conducive business environment and exploit the opportunities presented to facilitate energy access focusing on clean and renewable energy technologies. This is a big test for the continent and thus it will either brought prosperity through facilitating universal energy access by effectively utilizing the opportunities brought by the crisis or the lack of energy access will continue affecting communities the ability to improve their livelihoods.

    Abstract Ethiopia has one of the most ambitious energy expansion programmes but to achieve these goals, policies must be aimed at localizing the development and manufacturing of energy technologies. However, the country is dependent on importing solar and wind energy technologies. The aim of this paper is therefore to explore the challenges of locally developing and manufacturing solar and wind energy technologies, the necessary assets and policy instruments that can facilitate localization of energy technologies. This was achieved through survey questionnaire and interview from different stakeholders. The results show that the region has very limited capability of developing and manufacturing of solar and wind energy technologies because of lack of investment capital, under developed solar and wind supply chain, lack of skilled workforce and others. To overcome these challenges, financial incentives for research and development, solar and wind based power generation, manufacturing are considered as the top policy instruments with other policies included in this paper. Therefore, a proper implementation of the internationally proven policy instruments recommended in this paper are urgently needed in the region in order to achieve one of the sustainable development goals that stipulate facilitation of the implementation of modern, affordable and sustainable energy to the society.

This paper systematically discusses intelligent manufacturing technologies with an aim to map out their importance and industrial applicability and to show their significance to contain COVID-19 pandemic. Intelligent Manufacturing Systems (IMS) is then adapted as a post COVID-19 recovery and growth opportunity to ensemble to production processes of manufacturing industry in the sub-Saharan countries. Proposition of a Triple Helix Collaboration Eco-system that delineate a recursive contribution of Government(s), academia, and industry accompanies the IMS adoption. The intention is to shape the existing industrial challenges through networking in the area of intelligence technologies. While proposing the Eco-system, a post COVID-19 recovery and growth opportunity and intra-Africa scientific collaborations are taken into account.

    Abstract As part of the global effort in the development and deployment of renewable energy, Ethiopia is aggressively working to increase the share of those energy resources into the energy mix. Ethiopia is known for the use of hydropower generation systems but recently the country is introducing wind energy technologies and developed wind farms that started power generation in 2011. However, the public perception towards this new entrant of power generation system is not well understood. This paper therefore explores the perception of the public living within the wind farms. This is achieved through structured survey and conducting household level discussions with the community. The results showed that generally the public is supportive of such development but critical issues have been raised such as lack of prior consultation with the community by the developers, fairness of land compensation and generally lack of inclusive benefit packages from the wind farm development for the community. With the country planning for new wind farm development, it is crucial to devise comprehensive solutions and consider the recommended policy directions in this paper in order to develop public confidence and ownership for sustainability of the developed power generation systems.

    Abstract Africa has limited capacity to develop its own energy technologies and has been largely dependent on importation for its economic development. It is anticipated that there will be huge challenge for the very limited manufacturing industries in the continent to respond to the increasing energy demand. This will largely require the up scaling of the local manufacturing industries in-terms of skills, design capability, engineering management, manufacturing process and other related issues. Experiences from the developed world showed that academics and industries play critical role in innovation and technology development with proper policy and focus from the policymakers. African academics and industries could play similar role but requires revitalizing with enabling policies and sufficient funding. For this reason, African governments should prioritize their policies and investments towards achieving local energy technology development and innovation in order to build resilient economy. In light of this, we provided necessary recommendations for African led development pathways and policies to promote local manufacturing of energy technologies. This will have huge implications in supporting post COVID recovery and sustainable growth of the African countries.

    Abstract This paper investigates the influence of wake interaction and blockage on the performance of individual turbines in a staggered configuration in a tidal stream farm using the CFD based Immersed Body Force turbine modelling method. The inflow condition to each turbine is unknown in advance making it difficult to apply the correct loading to individual devices. In such cases, it is necessary to establish an appropriate range of operating points by varying the loading or body forces in order to understand the influence of wake interaction and blockage on the performance of the individual devices. The performance of the downstream turbines was heavily affected by the wake interaction from the upstream turbines, though there were accelerated regions within the farm which could be potentially used to increase the overall power extraction from the farm. Laterally closely packed turbines can improve the performance of those turbines due to the blockage effect, but this could also affect the performance of downstream turbines. Thus balancing both the effect of blockage and wake interaction continues to be a huge challenge for optimising the performance of devices in a tidal stream farm.
