The choice of fuels has frequently been at the center of debates about how a future low-carbon mobility system can be achieved. This paper introduces two visions of biogas fuels and electricity using material from interviews and documents in Swedish transport. These visions are analyzed as interrelated sociotechnical imaginaries. To better understand the way visions of biogas and electric vehicles (EVs) dynamically shape and condition each other, four dimensions of sociotechnical imaginaries are further developed: spatial boundedness, temporality, coherence and contestation, and the socio-material relations they are associated with. Imaginaries of biogas and EVs differ with respect to these characteristics. The biogas imaginary is made up of locally bounded visions of the desirable future, showing how imaginaries can be fragmented and contested, often because of their embeddedness in local socio-material systems of resource use. This local boundedness is exemplified by contrasting cases of contested biogas imaginaries in the Swedish municipalities of Linköping and Malmö. The imaginary of EVs, in contrast, is more uniform nationally and even influenced by international expectations that in the future vehicles will be shared, electric, and autonomous. The qualities of these imaginaries shape the way they interrelate and coevolve as sociotechnical changes of the transport system unfold.

Abstract This paper examines the energy transition consequences on the oil and gas energy system chain as it propagates from net importing through the transit to the net exporting countries (or regions). The fundamental energy system security concerns of importing, transit, and exporting regions are analyzed under the low carbon energy transition dynamics. The analysis is evidence-based on diversification of energy sources, energy supply and demand evolution, and energy demand management development. The analysis results imply that the energy system is going through technological and logistical reallocation of primary energy. The manifestation of such reallocation includes an increase in electrification, the rise of energy carrier options, and clean technologies. Under healthy and normal global economic growth, the reallocation mentioned above would have a mild effect on curbing the oil and gas primary energy demands growth. A case study concerning electric vehicles, which is part of the energy transition aspect, is presented to assess its impact on the energy system, precisely on the fossil fuel demand. Results show that electric vehicles are indirectly fueled, mainly from fossil-fired power stations through electric grids. Moreover, oil byproducts use in the electric vehicle industry confirms the reallocation of the energy system components' roles. The paper's contribution to the literature is the portrayal of the energy system security state under the low carbon energy transition. The significance of this representation is to shed light on the concerns of the net exporting, transit, and net importing regions under such evolution. Subsequently, it facilitates the development of measures toward mitigating world tensions and conflicts, enhancing the global socio-economic wellbeing, and preventing corruption.

Low-carbon energy technology is the most fundamental way to control carbon emissions. The Sanjiangyuan region in Qinghai Province must put environmental conservation in first place during development, because of its important function of national ecological protection. The comprehensive benefits of photovoltaic technology in this area need to be evaluated. In this paper, a new multicriteria decision model (MCDM) is established, with the four dimensions of “environment-society-economy-population”, and 16 specific indicators are developed by combining the coupling coordination degree (CCD) and the decision-making trial and evaluation laboratory (DEMATEL) method. MCDM can contribute to screening out key indicators that should be of high concern. The evaluation results show that the four dimensions of “environment-society-economy-population” in the Sanjiangyuan region are highly correlated, and the PPAT is creating a coordinated development; the elements of population and environment play a decisive role in the comprehensive benefits based on five key indicators and three indicative indicators. The paper provides suggestions for the local government to further implement the PV poverty alleviation industry, under the condition that the natural environmental capacity of the region and the natural ecosystem are fully respected and undisturbed.

Abstract With the rise of the sharing economy and the concept of “green environmental protection and low-carbon travel”, the emerging project of shared electric vehicles is booming. However, the accompanying coordination problem between shared electric vehicles and public transportation system needs to be urgently solved. In reality, customers’ choice of travel mode is influenced by their own travel perceived utility. Thus, this paper will discuss the competition and coordination problem between shared electric vehicles and public transportation system from the perspective of customer travel utility. Considering the travel cost and comfort in the customer travel utility, the game models of shared electric vehicle and public transport system in different scenarios are established by using competitive game and cooperative game. Then, the equilibrium solutions under different scenarios are obtained by solving the models. The analysis results show that shared electric vehicles would bring some beneficial improvements to the transportation system under certain circumstances. Furthermore, public transportation system should adopt a coordination strategy with the shared electric vehicles to promote the total customer travel utility for the entire system. It is worth considering the improvement of the service quality of shared electric vehicle and public transportation next, which would affect the rate of increasing in the total customer travel utility.

The short driving range and long charging time are two big problems for electric vehicles. A concept of battery pack automatic replacement is put forward in this paper to solve these problems, and a deep research on the key techniques is contained. This paper introduced the way of positioning and locking in replacement process, including the concrete structure of both replacing equipment and battery pack. For reliability problems of the connectors, two schemes are designed. Elastic jacks and coil are adopted to guarantee the reliability and automatically centering. On this basis, battery fast replacing system is designed, which controlled by PLC, driven by electro-hydraulic servo. This was proved to be a big success in practice.

Low Carbon Technologies

To implement EU climate policy, the UK’s New Labour government (1997–2010) elaborated an ecomodernist policy framework. It promoted technological innovation to provide low-carbon renewable energy, especially by treating waste as a resource. This framework discursively accommodated rival sociotechnical imaginaries, understood as visions of feasible and desirable futures available through technoscientific development. According to the dominant imaginary, techno-market fixes stimulate low-carbon technologies by making current centralized systems more resource-efficient (as promoted by industry incumbents). According to the alternative eco-localization imaginary, a shift to low-carbon systems should instead localize resource flows, output uses and institutional responsibility (as promoted by civil society groups). The UK government policy framework gained political authority by accommodating both imaginaries. As we show by drawing on three case studies, the realization of both imaginaries depended on institutional changes and material-economic resources of distinctive kinds. In practice, financial incentives drove technological design towards trajectories that favour the dominant sociotechnical imaginary, while marginalizing the eco-localization imaginary and its environmental benefits. The ecomodernist policy framework relegates responsibility to anonymous markets, thus displacing public accountability of the state and industry. These dynamics indicate the need for STS research on how alternative sociotechnical imaginaries mobilize support for their realization, rather than be absorbed into the dominant imaginary.

The paper analyzes particular aspects of a competitive economy based on low carbon emissions, which requires a fundamental change in consumer behavior, by focusing mainly on green acquisitions. The article contributes to the literature by the novelty of the researched problem: identification and analysis of the attitude and behavior of Romanian students regarding the electric vehicles acquisition. Thus, a quantitative marketing research was conducted, using a sample of 1221 students from 11 Romanian university centers. Also, the paper includes an overview regarding the costs and financial benefits provided by the Romanian Government to the electric vehicles owners, such as acquisition price reductions or tax reductions. The research results show that only half of the students are familiar with the concept of green consumption, and 37.8% of them are interested in buying an electric vehicle, the main reason being the fuel consumption. The authors recommend to the state’s institutions to develop special programs, by offering attractive facilities to the young people with higher education, as potential buyers, for the purchase of electric vehicles, this way diminishing the barrier effect generated by the high price. The academic environment should initiate research, both at the micro and macroeconomic level, to quantify the economic-social implications of green acquisitions in general and electric vehicles in particular.

AbstractAnalysis of the spatial elements of popular music recordings can be made by way of the ‘sound-box’, a concept that acknowledges the way sound sources are perceived to exist in four dimensions: laterality, register, prominence, and temporal continuity. By late 1972 producers working across a range of styles and in different geographical locations had adopted a normative positioning of sound sources across these dimensions. In 1965 no such norm existed. This article contextualizes the notion of the sound-box within academic discourse on popular music and explores the methodology employed by a research project that addressed the gradual coming-into-existence of the norm, which the project defined as the diagonal mix. A taxonomy of types of mix is offered, and a chronology of the adoption of the diagonal mix in rock is presented.
