The ECOWAS region has one of Africa's highest potentials for energy production, including both non-renewable (oil, gas, and uranium) and renewable sources (hydroelectric, solar energy, wind energy). Despite this significant potential, the region deals with a number of issues that affect its energy strategy. A review and analysis of the social, political, and economic factors influencing regional energy policy are provided in this paper, along with an assessment and forecast of energy policy in the ECOWAS. The analysis of regional energy policy then takes into account demand management, clean energy production, regional energy trade, and hydrocarbon exploration and production. The results show that the ECOWAS nations have started their transition to a renewable energy-based economy. These policies have long-term implications on the world's energy system and have the potential to improve the region's energy policy, even if the consequences are not immediately noticeable.
Senegal has been investing in the development of its energy sector for decades. By using a novel multi-criteria decision analysis (MCDA) based on the principal component analysis (PCA) method, this paper develops an approach to determine the effectiveness of Senegal’s policies in supporting low-carbon development. This was determined using six criteria (C1 to C6) and 17 policies selected from the review of Senegal’s energy system. In order to determine the optimal weighting of the six criteria, a PCA is performed. In our approach, the best weighted factor is the normalized version of the best linear combination of the initial criteria with the maximum summarized information. Proper weighted factors are determined through the percentage of the information provided by the six criteria kept by the principal components. The percentage of information is statistically a fit of goodness of a principal component. The higher it is, the more statistically important the corresponding principal component is. Among the six principal components obtained, the first principal component (comp1) best summarizes the values of criteria C1 to C6 for each policy. It contains 81.15% of the information on energy policies presented by the six criteria and was used to rank the policies. Future research should take into account that when the number of criteria is high, the share of information explained by the first principal component could be lower (less than 50% of the total variance). In this case, the use of a single principal component would be detrimental to the analysis. For such cases, we recommend a higher dimensional visualization (using two or three components), or a new PCA should be performed on the principal components. This approach presented in our study can serve as an important benchmark for energy projects and policy evaluation.
In Africa, switching to renewable energy sources with low carbon emissions is becoming more popular. In the Economic Community of West African states (ECOWAS), the low-carbon energy transition must overcome significant obstacles, including those posed by policies put in place and their implementation. In order to replace the current fossil fuel-driven economy with low-carbon development that also advances the regional aims and Sustainable Development Goals (SDGs), this paper analyzes the current policy landscape in the region. A total of 75 policies from four categories (energy access, energy efficiency, renewable energy, climate change) were chosen for the policy review. Multicriteria decision analysis and a thorough review of the literature have shed light on how well the policies of the ECOWAS countries could promote low-carbon development and what the main challenges to overcome are. The last step was the comparison of the progress of the two key policies in the region: the National Energy Efficiency Action Plan (NEEAP) and National Renewable Energy Action Plan (NREAP). The results illustrate the amount of work still needing to be done in the region, with only 26 of the 75 policies receiving a score above 50. However, the prospect of a better energy strategy that adequately considers the difficulties of the energy transition is possible, given the progress made by the region’s nations since the creation of national action plans for energy efficiency (EE) and renewable energy (RE). Our analysis has also shown that countries like Senegal have obtained quite promising results, as evidenced by the best scores of 76.88 and 73.25, respectively, obtained by its NREAP and NEEAP policies.
