Thus, focusing on this sector is essential in the effort to reduce the environmental and economic costs of energy usage. In this study, a municipal sewage heat recovery system is proposed to supply the thermal demand of the building throughout the year. A Solar-PV system that feeds energy to the heat pumps and water pumps of the sewage heat recovery system is proposed to make the heating system 100 percent renewable and carbon-free. In addition, Solar-PV surplus energy after operating sewage heat recovery system is used to power electrical equipment in a residential building system with 826 apartment units in Ontario, Canada. The findings of this study can assist researchers to gain a better understanding of the technical and financial challenges of replacing the conventional energy systems with renewable and alternative energy solutions in the residential sector.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"93 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132580126","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 use of solar energy can have a positive effect on the environment when it replaces or reduces the use of other energy sources that have greater environmental impacts. However, there are environmental issues related to the production and use of solar energy technologies to select the most suitable technologies for each location. In this work, a comparative study was conducted of the various photovoltaic technologies for one year in each of the two Moroccan cities, Rabat and Mohammedia, located approximately 57.33 km apart. The three panel technologies studied are monocrystalline technology (m-Si), polycrystalline technology (p-Si) and amorphous technology (a-Si) with a power of 2.04 KWh each. The photovoltaic (PV) systems were installed in order to determine which technology produces the most clean electricity. It is based on a comparison of the monthly production of the three technologies in the two cities, and the justification of the behaviour of the three technologies using two similar weather stations installed near the solar panels. In such a way, the determination of the climatic conditions will justify the behaviour of the three technologies. The comparative analysis included annual energy efficiency, performance ratio, annual energy density and system efficiency. Thus, with these performances, we can observe that photovoltaic installations with polycrystalline are appropriate in Mohammedia, whereas in Rabat they are monocrystalline.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131750633","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 conventional approaches for energy production may not be sufficient to meets these requirements. This necessitates energy production from different renewable sources through suitable techniques. In the present study, energy recovery from palm leaflet waste (PLW) in Morocco was examined. PLW is the by-product of palm farms and is usually burnt in the field or barren lands. This causes the emission of carbon dioxide (CO2) and of other air pollutants, as well as the outbreak of fires in the fields, which destroy a large number of palms. The purpose of this study was to identify and calculate the theoretical energetic potential (Ep) that can be recovered from PLW using anaerobic digestion (AD) and thermochemical conversion (TC) i.e., combustion. To estimate the theoretical heating value for TC, an elementary analysis was used. The processes of AD and TC on PLW led to the generation of energetic potentials (EP) of 69.81 GWh/y and 235.5 GWh/y, respectively. This work could be used as a guide by the countries having the same nature of biomass to make a preliminary energy study. This would ultimately lead to the development of processes that can end the energy crisis worldwide.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115391031","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 concern for instigating appropriate housing for breeders/cultivators/farmers is increasingly appearing of interest for different private, public, and government investors, leading to initiatives but only at clueing or ideas stages, with very limited concrete responses that mostly carry on the sustainable agri-ecology in general. This project explores the techniques and technologies of constructing an energy efficient model of agriculture housing, adapted to the local context for most existing residential dwellings from local materials. The need for a sustainable approach to address these appearing threats of resource exhaustion and environmentally alarming practices in agriculture that cannot be modulated. The project also contends with sustainable industrial agriculture key-solutions for developing countries and sub-Saharan Africa in perspective. The driver of this paper is to establish research of the best efficient agriculture housing and related practices through developing real scale test facility and implementing the suitably-adapted model to the Moroccan context for the optimum envelope performance in agricultural environments. This test facility will also address the energy savings policies and regulations through activities such as program evaluations for sustainable energy use in agriculture.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127081877","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}

Zimbabwe plans to install 1100MW and 2100MW of renewable energy by 2025 and 2030 respectively. Of the 2100MW to be developed and installed by 2030, 275MW (13%) is anticipated to be from biomass based renewable energy technologies corresponding to 28% utilisation of the national biomass-based energy potential. It has been noted that provided for biomass-based policy interventions for power generation are limited to biogas production hence the need to explore other commercially available such as pyrolysis and gasification as well as those under piloting and demonstration like hydrothermal liquefaction, hydro pyrolysis and coal-biomass energy with carbon capture and storage (CBECCS).
