The emergence of the COVID-19 (coronavirus disease of 2019) pandemic in 2020 and the ensuing state of emergency issued by the Japanese government, which was enforced from April 6 to May 25, 2020, changed our collective lifestyle dramatically. An increase in time spent at home resulted in a change in energy consumption structure. This study aimed to estimate the change in energy consumption at home during and after the state of emergency in Kobe, Japan. Six types of household energy consumption models were created based on the age of the head of household, the number of household members, and the floor area. The usage time and energy consumption of consumer durables were estimated for each model type. The model analysis results revealed that energy consumption during and after the state of emergency increased by 4.2% and 3.7%, respectively, compared to consumption before the state of emergency.

Limited water accessibility threatens the development of communities, especially where agriculture is the main income source. The implementation of decentralized Energy-WaterFood systems is a promising approach to improve the situation in these communities, creating synergies and improving the profitability of the system. The model urbs optimizes EnergyWater-Food systems to generate the highest revenues, considering the local conditions and sustainability limits. This work improves the hydrogeological part of urbs in order to model the water potential of a given community, establishing interrelations of the water sector with the energy and food sectors, and maximizing the long-term benefits within the sustainability limits. The proposed method was applied to the rural community of St. Rupert Mayer in Zimbabwe. In order to analyse the impact of data uncertainty on the model results, the sensitivity of the main input parameters is analysed. The results indicate that it is important to implement reliable input data for dimensioning the proper system configuration, as otherwise the whole system would not be sustainable.

Common problem in the operation of breastshot water wheel in Indonesia is discontinuity operation of the wheel due to very low stream velocity in the channel during dry season. In order to minimize the problem, it is important to study the method of maintaining the continuity operation of the wheel during dry season. Thus, the installation of water-jumper at upstream of the wheel is proposed in the present work. The laboratory models of the water channel and breastshot water wheel were fabricated. The water jumper is attached at the upstream whose slope angle can be adjusted. The present work investigates the effect of water-jumper slope on the performance of the breastshot wheel. The slope angles are set at 5°, 10°, 15°, 20°, 25°, 30°, 35°, and 40°and the upstream velocities are 1.1, 1.2, 1.3, 1.4, 1.5, and 1.6 m/s. The result reveals that the use of water-jumper can increase the gross head and hydraulic power of very low stream, and hence the torque and the output power of the breastshot wheel are enhanced. The highest efficiency is achieved at the slope angle of 10o for stream velocity of 1.3 m/s. The water-jumper gives significant effect at stream velocity lower than 1.3 m/s. The hydraulic power is influenced by both discharge and gross head where they increase at increasing slope angle of the water-jumper. However, higher momentum losses occurs at the wheel for stream velocity higher than 1.3 m/s, thus output power and efficiency of the breastshot decreases even though hydraulic power increases. The water-jumper can keep continuous operation of the breastshot wheel in the irrigation channel during dry season.

Market penetration of electric vehicles is nowadays gaining considerable momentum and so is the move towards increasingly distributed clean and renewable electricity sources. The penetration rate varies among countries due to several factors, including the social and technical readiness of the community to adopt and use this technology. In addition, the increasing complexity of power grids, growing demand as well as environmental and energy sustainability concerns intensify the need for energy management solutions and energy demand reduction strategies. Hence, integration strategies for energy-efficiency in the building and transport sector are of increasing importance. The present study analyses key parameters leading to Electric Vehicle adoption, utilizing background data from countries where Electric Vehicles have already been introduced and adopted in everyday living, and presents a case study of an energy management scheme in Greece, where the penetration rate is still low. Based on the above, an optimization algorithm is proposed, where buildings, photovoltaic plants, storage systems, and Electric Vehicles (utilization of Vehicle to Grid technology) can efficiently meet the energy requirements and peak-hour energy demand, in both economic and sustainability terms. The study proposes a hybrid approach, based on Analytic Hierarchy Process methodology and Genetic algorithms, aiming to foster the diffusion of the Vehicle to Grid concept to support building energy demand.

The complex geometry of Francis turbine components can be defined parametrically so that automatic optimization techniques based on parametrization can be used. This is convenient for a hydraulic redesign of individual turbine elements. Considering the importance of the guide vane cascade in defining the flow entering the runner, a parametric design tool is established to design the stationary parts of a Francis turbine with variable-speed capabilities and optimize the guide vanes. For a given runner geometry and turbine operating conditions, variety of different guide vane designs may be produced. The calculation procedure for obtaining the curves which are basis for generating the stationary turbine components is performed in the software MATLAB. The script is then connected with the Computational Fluid Dynamics and Finite Element Method analysis software ANSYS Workbench to automate the process of geometry generation, meshing, modeling and simulation of three-dimensional stationary water flow in the turbine and structural analysis of the guide vanes. The tool proves to be very useful for collecting results related to the guide vane hydraulic and mechanical performance, towards obtaining an optimal guide vane design. A model of a Francis turbine is used as a test case.

It is a priority to develop intelligent irrigation systems to save water. Using optimal control formulations and techniques, one can make water consumption follow more closely the hydrological needs of the crop, taking into account current weather conditions. Here, the mathematical model presented by the authors in previous publications is improved. This new model incorporates new features like the soil slope, the possibility to include a percentage of water losses due to runoff, and a percentage of water losses if the soil is on the field capacity. A new and efficient replan strategy is applied, taking into account the data measured from moisture sensors to ensure that the hydric needs of the crop are fulfilled. A new approach to deal with multiple irrigation points is also proposed. It allows redistributing the available water if an irrigation point cannot provide the water needed.

Natural resource extraction and processing accounted for 23% of global greenhouse gas emissions in 2015. Therefore, reducing resource use through resource efficiency promises significant contributions to climate protection. This “climate-resource-nexus” has mostly been explored from a scientific, Global North-oriented perspective. The present study analysed potential interactions between climate and resource policy through literature review and exploratory interviews with experts from different world regions. It did not find a generic climate-resource-nexus policy. Scientific studies mostly address greenhouse gas emission reduction potentials of resource efficiency approaches, e.g., lifetime extension, material substitution, and recycling. Interview findings reveal that climate and resource policy measures will have to differ regionally to improve the relevance and fit and that silo culture may prevent an integrated climate-resource-nexus perspective. It is argued that creating an overarching line of policy reasoning through cross-departmental cooperation could help to overcome silos and grant flexibility to national and regional policy-making to adapt policies to their interviews with topical experts from international civil society and across different world regions. This paper presents findings from this research. The literature review reveals that policies-addressing academic publications mainly analyse potential GHG emission reduction effects of different material efficiency and circular economy strategies. However, the climate-resource-nexus appears to guide policy considerations hardly. Interview findings reflect this, as only a few interviewees mention mutual effects of climate protection and resource conservation policies. Those who mention interactions consider insufficient cross-departmental exchange and silo culture as reasons for the lack of climate-resource-nexus thinking in the policy. This kind of analysis could contribute to strengthening systemic nexus thinking in international climate and resource policy while also fostering a view on adapting policies to the needs of specific contexts. guideline questionnaires prepared to obtain the expertise of both regional climate and regional resource experts. Each questionnaire contained the same set of questions differing only in the policy measures exposed to expert feedback – climate protection policy for climate experts and resource policy (including circular economy) for resource experts. Furthermore, each questionnaire posed a question on the climate-resource-nexus, whether or not the measures discussed could impact resource use or GHG emissions in their regions.
