Summary The utilization of renewable energy resources (RERs) in the traditional power system has gained a global recognition owing to their technical, economic and environmental benefits. The techno‐economic analysis of a microgrid system that consists of diesel generator (DG), methanol generator (MG), photovoltaic (PV) and battery system (BS) is implemented in this study to evaluate the performance of the power system. The feasibility study of the power system is implemented by using HOMER application tool and meteorological data provided by the National Aeronautics and Space Administration. The analysis indicates that PV‐DG‐MG‐BS microgrid system is the most optimized configuration based on the net present cost (NPC) of $213 405.4, cost of energy (COE) of $0.256/kWh, renewable fraction of 88.6%, diesel fuel of 3055 L/y and DG operating hours of 1037 h/y. The results obtained from the optimized configuration translate to a substantial reduction in NPC, COE, diesel fuel and operating hours of DG when compared to the base case study. This indicates that the combination of DG, PV, MG and BS in a microgrid system is the most economical configuration to achieve a feasible result. Moreover, sensitivity analysis is carried out to investigate the impacts of solar radiation, load demand, fuel cost and inflation rate on the performance of the power system. The results obtained from the study clearly prove the effectiveness of using RERs to increase the sustainability and performance of the power system. This improves the standard of living and economic activities in areas where the microgrid systems are sited.

“…Conventionally and even until today, energy and waste management in household have been treated as independent domains. In relation to research in the energy domain (activities or processes related to consumption and production of energy), there are numerous optimisation studies [12][13][14] that focus on identifying the best form of energy supply system for households through minimising operation cost and environmental emissions. Üçtuğ and Azapagic [15] examined the environmental impacts of adopting residential-scale integrated solar PV-battery system in households in Turkey and concluded that the resulting impact is 1.6-82.6 times lower than grid electricity.…”

Households are highly resource intensive in terms of energy consumption and waste generation, and resource utilisation and management in households has wider implications at the national level. This paper applies systems thinking using a circular economy approach at the household level for the first time. The approach takes into consideration energy supply and demand, waste management and resource recovery from waste in a single system. Combining energy and waste management analysis enables better understanding of the systems at household level and can address resource efficiency, fuel poverty and environmental issues more effectively at the national level. This study adopts the Systems Thinking Approach to Resource Recovery (STARR) framework to identify the potential improvements that can be made within the system. Three models of households on energy and waste management, including "waste-and-energy", "waste-to-energy" and "reduced consumption" models, are examined through assessments of economic, environmental and social dimensions. These models are further explored through different scenarios, by considering the adoption of renewable solar photovoltaic (PV) energy supply, increasing recycling rate, integrating energy from waste into household and reducing consumption of resources and waste generation. The scenario with the least environmental impact involves adopting a concerted approach through switching to solar PV, increasing recycling rate from 45 to 60% and sending 100% of residual waste into energy recovery (i.e. within the "waste-to-energy" model), with global warming potential (GWP) of −1308 kg CO2equivalent/year and total saving/income of £680 per year, on a one household basis.
