“…Integrating these four abilities into the system would enable it to continuously address "availability", "accessibility", "affordability", and "acceptability" as the four sustainability-related dimensions of energy [17]. Some strategies to improve energy resilience in cities can be summarized as follows [19]:…”

Energy resilience can be reached with a secure, sustainable, competitive, and affordable system. In order to achieve energy resilience in the urban environment, urban-scale energy models play a key role in supporting the promotion and identification of effective energy-efficient and low-carbon policies pertaining to buildings. In this work, a dynamic urban-scale energy model, based on an energy balance, has been designed to take into account the local climate conditions and morphological urban-scale parameters. The aim is to present an engineering methodology, applied to clusters of buildings, using the available urban databases. This methodology has been calibrated and optimized through an iterative procedure on 102 residential buildings in a district of the city of Turin (Italy). The results of this work show how a place-based dynamic energy balance methodology can also be sufficiently accurate at an urban scale with an average seasonal relative error of 14%. In particular, to achieve this accuracy, the model has been optimized by correcting the typological and geometrical characteristics of the buildings and the typologies of ventilation and heating system; in addition, the indoor temperatures of the buildings—that were initially estimated as constant—have been correlated to the climatic variables. The proposed model can be applied to other cities utilizing the existing databases or, being an engineering model, can be used to assess the impact of climate change or other scenarios.

“…Records from IRENA show that while global urbanization increased from 43.5% in 1990 to 54% in 2014, urban energy consumption rose from 45% to about 65% within the same period (Ferroukhi et al, 2016). Sugahara & Bermont (2016) shows that energy consumption in cities of OECD countries is substantially greater than that of rural areas. Urban energy demand will increase more quickly since its energy consumption grows faster than rural areas as it consumes more fossil fuels.…”

“…These dimensions constitute the energy 'trilemma' (Kim et al, 2017). Cities will also be pursuing self-reliance in energy matters through a renewable-based decentralization of energy production (Morris & Oska, 2008) and work towards achieving resilience (Sugahara & Bermont, 2016). The link between renewable energy and the city is further demonstrated in Figure 1.…”

Cities are unique centers of energy demand and greenhouse gas emissions. Although electricity provides multiple functions for urban residents, its supply in Nigerian urban centers is poor, and the attempts to understand this problem have been limited to national level. Therefore, this study aims to explore the dimensions of electricity supply problem; assess adaptations by households to inadequate electricity supply; examine the use of renewable energy-related facilities; and understand the perception of renewables by urban households, with five residential neighborhoods in Minna, the capital of Niger state, were covered. Data were collected using a questionnaire and the Facility Observatory Technique to document daily electricity supply to households. The collected data covered electricity connection, daily supply, adaptations to inadequate public supply, perception of renewable energy and willingness to shift to renewable electricity sources. Results indicate that households in Minna have an average of 5 hours of electricity daily, while only 25% have electricity at night (7.00pm and 10.00pm.). An index derived to demonstrate the nature of electricity supply to households indicates that the city has a darkness index of 0.81, indicating a situation of extreme inadequacy of electricity supply. The index has a 95% correlation with the proportion of households without electricity at night. The study also shows that 72% of the households use fossil fuel-driven plants while 84% are not familiar with the use of renewable resources for generating electricity. The paper holds that the willingness of the public to switch to renewable energy, the incremental nature of urban development, and the high costs incurred by households for non-sustainable alternative sources of electricity provide the foundation for a more concerted effort to develop renewable energy as a means of improving the availability of electricity in Nigerian urban centers.
