    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

    Policy, Geospatial, and Market Factors in Solar Energy: a Gestalt Approach

    Get PDF
    abstract: Our dependence on fossil fuels is driving anthropogenic climate change. Solar energy is the most abundant and cleanest alternative to fossil fuels, but its practicability is influenced by a complex interplay of factors (policy, geospatial, and market) and scales (global, national, urban). This thesis provides a holistic evaluation of these factors and scales with the goal of improving our understanding of the mechanisms and challenges of transitioning to solar energy. This analysis used geospatial, demographic, policy, legislative record, environmental, and industry data, plus a series of semi-structured, in-person interviews. Methods included geostatistical calculation, statistical linear regression and multivariate modeling, and qualitative inductive analysis. The results reveal valuable insights at each scale, but moreover a gestalt model across the factors and scales draws out a larger pattern at play of the transmutational weighting and increasing complexity of interplay as the level of analysis cascades down through the three geographic scales.Dissertation/ThesisDoctoral Dissertation Sustainability 201

    The role of the license plate lottery policy in the adoption of Electric Vehicles: A case study of Beijing

    Get PDF
    Policy is an influential factor to the purchase and usage of Electric Vehicles (EVs). This paper is focused on the license plate lottery policy, a typical vehicle purchase restriction in Beijing, China. An agent-based spatial integrated urban model, SelfSim-EV, is employed to investigate how the policy may influence the uptake of EVs over time at the individual level. Two types of “what-if” scenario were set up to explore how the methods to allocate the vehicle purchase permits and the number of permits might influence the EV market expansion from 2016 to 2020. The results suggested that 1) both the allocation methods and the number of purchase permits could heavily influence the uptake of EVs and further its impacts on vehicular emissions, energy consumption and urban infrastructures; 2) compared to the baseline, both scenarios got significantly different spatial distributions of vehicle owners, transport facilities, vehicular emissions and charging demand at the multiple resolutions; 3) SelfSim-EV was found as a useful tool to quantify the nonlinear relationships between the increase of EV purchasers and the demand for transport facilities and electricity, and also to capture some unexpected results coming out from the interactions in the complex dynamic urban system

    An Arm\u27s Length Evaluation of Octopus

    Get PDF
    This paper explores and evaluates the use of Octopus in Hong Kong (HK). There are over 7.4 million cards sold and 7 million of these are active. The study examines how transport and other sectors can enhance their services through Octopus. Six of the forty organisations using the Hong Kong Octopus card were interviewed. A convenience sample of 800 actual and potential Octopus customers was sent a questionnaire. Unprecedented growth in the use of smartcard devices had been recorded in recent years. They are expected to bring revolutionary changes to businesses, governments and members of the society. The implications from this study would therefore be useful for those organisations that use or plan to adopt and implement the technology. Results of the survey are discussed, including penetration rate, figures on card ownership and usage, failure rate, results from promotion schemes and loyalty programmes, success factors, users reliance of the system and areas of improvement. The major reasons for not using the system are addressed. Findings obtained from interview sessions were integrated in the discussion

    Global Gains from Liberalising Trade in Telecommunications and Financial Services

    Get PDF
    This paper uses a general equilibrium model to assess the effects of liberalising trade in telecommunications and financial services for 19 regions of the world. Results suggest that economies gain from removing barriers to the establishment of new operations (domestic or foreign), and by liberalising the operations of existing operators. For the world as a whole, the one-off gains are estimated to be at least 0.2 per cent of combined GNP, or about US$50 billion.trade in services - telecommunications - finance - financial services - general agreement on trade in services - GATS - trade liberalisation - global

    Economic Structure and Development in an Emergent Asian Economy: Evidence from a Social Accounting Matrix for Vietnam

    Get PDF
    Vietnam started a process of economic reform in 1986 and is presently opening up its economy to regional and global economic forces. As a result, Vietnam faces significant challenges in the area of economic policy analysis. This paper reviews insights emerging from a detailed social accounting matrix (SAM), compiled for the year 2000. The SAM reflects Vietnam’s heavy reliance on primary sector activities, but we also find that agricultural potential could be expanded significantly. In other sectors, the critical importance of sustained commitments to human capital development is apparent. In this context, the international donor community can support the ongoing transformation process through concerted training and capacity building initiatives that have proven successful elsewhere in the region.Economic structure,Economic reform, Vietnam

    Asian Energy and Environmental Policy: Promoting Growth While Preserving the Environment

    Get PDF
    Asia has truly experienced spectacular economic growth over the past 15 years. However, this economic progress has come at a high cost. It has led to unprecedented environmental consequences. The ecological footprint shows that, despite the fact that one-fifth of the population in Asia still lives on less than US$ 1 per day (PPP-adjusted), the region is already living beyond its ecological carrying capacity. The region is facing a dilemma. On the one hand, continued economic growth is needed to alleviate the poverty of the two-thirds of the world’s poor living in this region. On the other hand, that economic growth will further place tremendous strains on the natural environment. In order to extricate itself from this difficult position, the region needs to shift the conventional pattern of “develop first and then treat the pollution” to a different trajectory of sustainable development. To that end, this paper examines a variety of policy responses at national, regional and international levels to deal with growing concerns about the environmental challenges in Asia in order to help to put the region on a more sustainable development path. In the context of national responses, special attention is paid to the following issues: coordination between the central and local governments, market-based environmental instruments and industrial policies, tougher emissions standards for mobile and stationary sources and for fuel quality, policies to promote energy efficiency and the use of clean energy and biofuels, the integration of environmental policies with economic and sectoral policies, and engagement of the private sector through e.g., ecolabelling, green government procurement, corporate ratings and disclosure programs, and drawing the support of financial institutions to promote improved corporate environmental performance. It is concluded that having the right policy mix, coupled with strengthened cooperation at national, local and regional levels, will ensure continuing economic growth in the region without compromising its limited ecological carrying capacity and environmental quality.Energy policy; Market-based environmental instruments; Asia
