Assessing the performance of a monocrystalline solar panel under different tropical climatic conditions in Cameroon using artificial neural network

To implement the European Union (EU)-Africa Green Energy Initiative in Cameroon to boost the renewable energy sector, we model the performance of a 500 W monocrystalline solar panel in major cities of Cameroon located in different climatic zones to select the best location for the installation of a solar farm. We also evaluate the contribution of seasonal and weather variability to the amount and stability of power generated by the panel using the artificial neural network (ANN). The ANN model was used to train and test the ERA5 hourly data for Bamenda. The model was then used to estimate Photovoltaic (PV) output in Douala, Yaounde, Ngaoundere, Garoua, and Maroua with a mean absolute error of 4.109 × 10−5, 4.699 × 10−5, 3.563 × 10−5, 3.106 × 10−5, and 3.083 × 10−5 kW, respectively. The results show that the ANN can capture the influence of weather variability on the generated output power. Cloud cover and rainfall are found to negatively affect the amount and stability of generated power in the lower latitude cities of Douala and Yaounde compared to the northern cities, with these effects being stronger in the rainy season than in the dry season. Garoua followed by Maroua are proving to be the best locations for installing a solar park in terms of the amount and stability of electricity generated throughout the year. The Cameroonian government, its EU partners, and other stakeholders involved in the development of solar energy in the country will be able to use the results of this study for better decision-making.

The environmental repercussions of financial development and green energy in BRICS economies: From the perspective of new composite indices

This study is significant because it fills the gap in future literature by looking at the panel of 5 Brazil, Russia, India, China, and South Africa (BRICS) economies regarding the important role of financial development (FD) in environmental deterioration under the holistic measures of FD and environmental quality, something that has been largely overlooked in preceding studies. Consequently, this study explores the environmental effects of FD, employing a composite environmental quality proxy (CEQP) and a composite FD proxy (CFDP). In pursuit of this objective, the continuously updated fully modified (Cup-FM) and continuously updated bias corrected (Cup-BC) procedures are applied. These procedures enabled us to comprehensively explore the dynamic interactions between the combined index for FD and CEQP controlling agricultural activities, economic growth, renewable energy consumption, and nonrenewable energy consumption (NREC) in the panel of 5-BRICS economies from 2005 to 2019. The empirical results show that CFDP appeases environmental deterioration and thus improves environmental quality. The agricultural activities intensify environmental deterioration. The analysis also reveals a U-shaped relationship between the CEQP and economic growth (inverted U-type environmental Kuznets curve hypothesis) for the BRICS nations. Additionally, renewable energy improves environmental quality, whereas NREC decreases it. As supported by the results of the study, BRICS policymakers should encourage the financial sector to support green energy initiatives and achieve environmental stability.

CODAS–Hamming–Mahalanobis Method for Hierarchizing Green Energy Indicators and a Linearity Factor for Relevant Factors’ Prediction through Enterprises’ Opinions

As enterprises look forward to new market share and supply chain opportunities, innovative strategies and sustainable manufacturing play important roles for micro-, small, and mid-sized enterprises worldwide. Sustainable manufacturing is one of the practices aimed towards deploying green energy initiatives to ease climate change, presenting three main pillars—economic, social, and environmental. The issue of how to reach sustainability goals within the sustainable manufacturing of pillars is a less-researched area. This paper’s main purpose and novelty is two-fold. First, it aims to provide a hierarchy of the green energy indicators and their measurements through a multi-criteria decision-making point of view to implement them as an alliance strategy towards sustainable manufacturing. Moreover, we aim to provide researchers and practitioners with a forecasting method to re-prioritize green energy indicators through a linearity factor model. The CODAS–Hamming–Mahalanobis method is used to obtain preference scores and rankings from a 50-item list. The resulting top 10 list shows that enterprises defined nine items within the economic pillar as more important and one item on the environmental pillar; items from the social pillar were less important. The implication for MSMEs within the manufacturing sector represents an opportunity to work with decision makers to deploy specific initiatives towards sustainable manufacturing, focused on profit and welfare while taking care of natural resources. In addition, we propose a continuous predictive analysis method, the linearity factor model, as a tool for new enterprises to seek a green energy hierarchy according to their individual needs. The resulting hierarchy using the predictive analysis model presented changes in the items’ order, but it remained within the same two sustainable manufacturing pillars: economic and environmental.
