The Clean Energy States Alliance (CESA) has produced a new report for states and municipalities on solar+storage for low- and moderate-income (LMI) communities. The report explains how solar+storage can benefit LMI residents and describes a variety of policy tools for doing so, including grants, rebates, utility procurement standards, financing support, opening markets, and soft cost reduction

Transforming Energy Networks via Peer to Peer Energy Trading: Potential of Game Theoretic Approaches

Peer-to-peer (P2P) energy trading has emerged as a next-generation energy management mechanism for the smart grid that enables each prosumer of the network to participate in energy trading with one another and the grid. This poses a significant challenge in terms of modeling the decision-making process of each participant with conflicting interest and motivating prosumers to participate in energy trading and to cooperate, if necessary, for achieving different energy management goals. Therefore, such decision-making process needs to be built on solid mathematical and signal processing tools that can ensure an efficient operation of the smart grid. This paper provides an overview of the use of game theoretic approaches for P2P energy trading as a feasible and effective means of energy management. As such, we discuss various games and auction theoretic approaches by following a systematic classification to provide information on the importance of game theory for smart energy research. Then, the paper focuses on the P2P energy trading describing its key features and giving an introduction to an existing P2P testbed. Further, the paper zooms into the detail of some specific game and auction theoretic models that have recently been used in P2P energy trading and discusses some important finding of these schemes.Comment: 38 pages, single column, double spac

Autonomous Mobility and Energy Service Management in Future Smart Cities: An Overview

With the rise of transportation electrification, autonomous driving and shared mobility in urban mobility systems, and increasing penetrations of distributed energy resources and autonomous demand-side management techniques in energy systems, tremendous opportunities, as well as challenges, are emerging in the forging of a sustainable and converged urban mobility and energy future. This paper is motivated by these disruptive transformations and gives an overview of managing autonomous mobility and energy services in future smart cities. First, we propose a three-layer architecture for the convergence of future mobility and energy systems. For each layer, we give a brief overview of the disruptive transformations that directly contribute to the rise of autonomous mobility-on-demand (AMoD) systems. Second, we propose the concept of autonomous flexibility-on-demand (AFoD), as an energy service platform built directly on existing infrastructures of AMoD systems. In the vision of AFoD, autonomous electric vehicles provide charging flexibilities as a service on demand in energy systems. Third, we analyze and compare AMoD and AFoD, and we identify four key decisions that, if appropriately coordinated, will create a synergy between AMoD and AFoD. Finally, we discuss key challenges towards the success of AMoD and AFoD in future smart cities and present some key research directions regarding the system-wide coordination between AMoD and AFoD.Comment: 19 pages, 4 figure

Eras of electric vehicles: electric mobility on the Verge. Focus Attention Scale

Daily or casual passenger vehicles in cities have negative burden on our finite world. Transport sector has been one of the main contributors to air pollution and energy depletion. Providing alternative means of transport is a promising strategy perceived by motor manufacturers and researchers. The paper presents the battery electric vehicles-BEVs bibliography that starts with the early eras of invention up till 2015 outlook. It gives a broad overview of BEV market and its technology in a chronological classification while sheds light on the stakeholders’ focus attentions in each stage, the so called, Focus-Attention-Scale-FAS. The attention given in each era is projected and parsed in a scale graph, which varies between micro, meso, and macro-scale. BEV-system is on the verge of experiencing massive growth; however, the system entails a variety of substantial challenges. Observations show the main issues of BEVsystem that require more attention followed by the authors’ recommendations towards an emerging market

Innovative Bike-Sharing Design as a Research and Educational Platform for Promoting More Livable Urban Futures

Studying the viability of innovative urban access design is the key in achieving optimum results when attempting to transform dogmatism referring to conventional car-orientation into a meaningful driver of modal change founded on the actual societal needs for future transportation. An efficient public bicycle scheme could be the very definition of a system that could encourage and even facilitate, in real terms, such a transition. This paper is discussing how a post-graduate course embraced, through the means of a service-oriented design exercise, the potential introduction of such a system. More specifically, seven research teams, closely guided by the three authors, were affiliated with designing a new hypothetical bike-sharing scheme in the city of Gothenburg, Sweden more captivating than the existing one. The paper reports on: a) the novel educational approach the tutors employed, b) the taught experiences that helped the students utilize their potential as learners but also as inventive designers, c) the research in terms of design results and d) the overall transition from solely serving the needs of automotive mobility in urban environments, to creating a knowledge platform that actually illustrates an improved design-innovation process to tackle future urban demands and eventually have a real-life context impact on the city of Gothenburg

Designing Innovative PV-powered applications for the urban environment:A design-driven multidisciplinary approach

The transport and residential sectors are two of the key areas where the transition to a fully renewable energy supply needs to take place in order to limit the emission of CO2 and other greenhouse gases. This thesis therefore explores how a multidisciplinary design-driven research approach can be used to develop technically functional, financially feasible and low-emissions PV-powered applications for these two sectors which are more likely to be adopted by end users. A feasibility model was first developed to simulate the operation of a grid-connected solar EV charging station with energy storage, showing that the longer an EV is driven the more affordable solar-powered charging becomes and a higher environmental dividend is achieved. A subsequent study for eight locations around the world indicates that with the right combination of battery and PV system sizes this charging system can be a feasible solution from a technical, financial and environmental perspective in comparison with both a gasoline-fuelled vehicle and a grid-charged EV. A conceptual design study resulted in the development of eleven innovative solar mobility applications, ranging from mobile EV charging stations to solar-powered bicycles and public transportation. Energy balance calculations for two sample locations show that the extent to which the PV electricity produced by these systems will meet vehicle demand will vary significantly depending on the type of application. Results from a user study aimed at evaluating the potential adoption of four existing solar-powered mobility applications found that despite having a mostly positive impression, respondents’ likelihood to adopt these applications in the near future was relatively low. However, a vast majority of respondents willing to pay more for an EV with integrated solar cells indicates that these applications are perceived as having an added value. Finally, the performance of home energy management system (HEMS) prototypes was evaluated using both simulation and user tests. This dual approach proved useful for quickly and accurately validating the operation of these products, but conflicting results during user tests highlight the complexity of user behaviour around household energy consumption and the importance of carefully designing HEMS to ensure they achieve their intended purpose

Strategies for shifting technological systems : the case of the automobile system

Californian and Dutch efforts to produce electric vehicles are explored and compared. Three strategies are put forward that could turn electric vehicles from an elusive legend, a plaything, into a marketable product: technology forcing creating a market of early promises, experiments geared towards niche development and upscaling (strategic niche management), and the creation of new alliances (technological nexus) which bring technology, the market, regulation and many other factors together. These strategies deployed in the Californian and Dutch context are analysed in detail to explore their relative strengths and weaknesses and to argue in the end that a combined use of all three will increase the chances that the dominant technological system will change. The succesful workings of these strategies crucially depend on the coupling of the variation and selection processes, building blocks for any evolutionary theory of technical change. Evolutionary theory lacks understanding of these coupling processes. Building on recent insights from the sociology of technology, the authors propose a quasi-evolutionary model which underpins the analysis of suggested strategies
