To assess the impact of sustainable and responsible tourism on local development in the community of Karongi, Western Province of Rwanda, and in order to determine the renewable energy resources’ (solar and hydropower) potential, an environmentally friendly tourism alternative is proposed. A quantitative technique was utilized in this study, with 265 area inhabitants completing a survey to determine their opinions on the idea. Furthermore, the potential for solar and hydroelectric energy was assessed in order to uncover durable options that the community may integrate into their own businesses and endeavors. There is a correlation between eco - tourism and economic growth, according to the research findings. Additionally, the evaluation of renewable energy resources potential reveals that it is feasible in this region.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"32 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130440553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, the revenue risks of renewable generators make it challenging for them to attract finance from traditional investors. Several mechanisms have been proposed to minimize these risks but have their limitations. Blockchain smart contract arrangements have emerged as a new marketplace, addressing the shortcomings of these traditional electricity hedging mechanisms. However, they have their peculiar challenges, potentially impeding their mainstream adoption in the renewable electricity industry. Hence, this paper develops a novel taxonomy of the risks and challenges of embracing blockchain smart contracts in facilitating renewable electricity transactions. Examining these issues indicates that the adoption of blockchain smart contracts in the renewable energy industry can be facilitated by cooperation and partnerships between technology developers and researchers, renewable energy companies, as well as governments.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123724922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This continues to bear fruit as we have witnessed improved statistics, engagement, and progress in the aspects of work-life balance, breaking barriers of gender biases and representation in executive positions across the sectors. However, there is room for improvement, while at the same time encouraging the younger generations to invest their time, careers, and research in STEM. Early mentorship of students from primary to university/tertiary levels through scholarships, internships, and employment opportunities, plays a pivotal role in supporting the education sector. It is essential to incorporate the intentional engagement of industry into the STEM academia to spark progress in key decision-making sectors and drive policy. This panel seeks to deliberate on the existing opportunities in the power sectors and engineering that encourages the continuous engagement of STEM education and the current structures across the region that supports such engagement.

Some 1.3% of the world’s electricity is consumed by the data centre (DC) industry and about 2% of the CO2 emissions across the globe come from the information technology (IT) sector. Because energy is a significant cost to DC operators, metrics have been developed to analyze its utilization. Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency (DCIE) are among the globally accepted standard metrics. This work applies PUE and DCIE metrics to evaluate energy utilization at Wananchi Group (Kenya) Limited DC, Nairobi, Kenya. Using monthly electricity bills from the local utility company, results show that the 2021 average annual PUE and DCIE metrics for the DC were 1.8 and 56% respectively. The values compare favorably with those from DCs in Europe (1.8 and 55.6 % respectively). Further, analysis shows that the case study DC facility mainly operates within the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) allowable envelope-class Al with minimal operation in the recommended envelope.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122153072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most promising environmentally friendly option, though at a high capital cost, is the installation of solar home systems. This paper investigates the technical and financial frameworks that may guide the leasing agreement for residential rooftops to guide potential investors. A survey was conducted to investigate the awareness and economic status of residential consumers. An exponential smoothing method was used for forecasting the time-series solar power outputs and load profiles. It was determined that the minimum number of 280 W panels required to be installed in medium and high income residential areas is ten (10) (2.8kW). The installation cost of the entire system was determined to be ZMK 66000 (${$}$ 4000). It was discovered that a discounted rate of higher than 6.2% yielded a negative present value. However, the present value is positive for 3% and 5% discount rates, i.e. ZMK 8229 (USD 489.85) and ZMK25711 (USD 1530), respectively. A payback period of 15 to 20 years is expected with the client buying power at the current utility tariffs. If an agreement is made to reduce the payback period so that at the end of that period the installation ownership becomes that of the client then the cost of electricity should be adjusted to say, worlds average price of2.23 ZMK/kWh (USD 0. 133/kWh. Since the installation lifecycle is 25 years, the saving on electricity by the client is about ZMK 200000 (${$}$ 12000).","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121521326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
