This paper discusses the application of distributed energy resources (DERs) at water resource recovery facilities (WRRF). The DERs considered include solar photovoltaic (PV) systems, biomass electricity generation, and energy storage systems (ESS). The financial and demand management implications of the deployment of various DER combinations are analyzed. The load profile of a single plant is studied in order to draw conclusions regarding the optimal size for energy storage solutions based on the goals of the WRRF. A case study of a Medium sized WRRF, located in a large metropolitan area, is used to compare different financial and technical implementation strategies. An ideal combination of DERs is determined based on analysis of various scenarios for nine distinct use cases. The overarching goal of this paper is to understand the potential of various combinations of DERs for managing peak demand and resilience at WRRFs. Elements in the financial models are compared to determine the combination that creates a financially viable project while providing tangible benefits in resilience and/or demand management to the WRRF. • Energy efficiency is key for urban regions to combat global warming. • Distributed energy resources (DERs) improve resiliency during power failures. • Energy efficiency is possible through deployment of DERs and better use of biogases • Distributed energy resources (DERs) improve resiliency during power failures.

Abstract: This paper assesses the energy and water consumption practices of existing housing in Saudi Arabia, with the ultimate aim of establishing guidelines for delivering sustainable residential buildings in the near future. In order to achieve this aim the current status of a typical Saudi residence (i.e. an apartment complex) is investigated in terms of energy and water consumption using simulation software packages. The paper then examines the prospects for applying various measures to the typical Saudi residence to manage energy and water use more sustainably. This research identifies several design-related faults common to Saudi Arabian house design. These faults contribute to an inefficient use of energy and domestic water resources. Finally, the paper puts forward a set of recommendations and guidelines, design-related and otherwise, to enhance the sustainability of future Saudi residential buildings. [ABSTRACT FROM AUTHOR]

• A practical multi-agent problem in the automobile industry is defined. • A comprehensive approach including System Dynamics and game theory is provided. • Energy efficiency, environmental awareness, and social welfare are considered. • A function for the average of vehicle kilometers traveled in a unit of time is suggested. • Several managerial insights for both manufacturers and governments are presented. This paper looks at the effects that environmental policies have on car manufacturers. A standing problem for car manufacturers is determining both a car's price and its level of energy efficiency. The South Korean government has sustainable goals that encompass saving energy, seeking revenue, and advancing social welfare. This study highlights four decision variables in two groups for the government. The government determines the optimal value of each goal, while maintaining a threshold for the two other goals as constraints. The four decision variables are determining the car sales tax, determining the fuel tax, determining the cost of educating the public about environmental awareness, and determining the percentage of government's cooperation in the manufacturer's research and development expenditure. For the purpose of this study, a new function, average of vehicle kilometer traveled in a unit of time (AVKT), is suggested for calculating the average distance driven by a car over a given period of time, based on the cost of fuel, the car's energy efficiency, the driver's environmental awareness quotient, and the rebound effect. This newly defined multi-agent problem is solved by looking at the structure of the Stackelberg game, and equilibrium solutions are offered by implementing the backward induction procedure. By considering demand and profit for fuel, this study offers the most efficient goals and strategies for both car manufacturers and fuel producers alike. Finally, this study offers several results and insights. [ABSTRACT FROM AUTHOR]
