Engine Power

The car is still the most common mode of transport in Western countries, particularly so across the European Union, as it accounts for about two-thirds of daily commuting. So far, measures aiming to reduce automobile traffic and incentives for the modal shift to public transport and non-polluting methods of travel (walking, cycling, etc.) have had little effect. Moreover, the car lies at the core of a very complex system that has proven to be difficult to unlock. In light of these challenges, using new types of engine power may appear to be a solution. Electric vehicles have the potential to improve the efficiency, affordability, and sustainability of the transport system. However, there remains much uncertainty as to how such a transition from one type of engine to another may unfold, and where it could take place within the European context. In June 2017, the H2020 project SHAPE-ENERGY launched an online debate on the Debating Europe platform with the question: “Should all cars be electric by 2025?”. The aim of the debate was to elicit citizens views on whether the goal could be reached, how and with which consequences. The diversity of the vantage points that have appeared in the subsequent discussion generated by the strands of debate allows us to bring into discussion the viewpoints and arguments that are not often addressed in the literature on the adoption of electric cars in a comprehensive way. The article sheds light on those debates across Europe, in order to bring new insights to European policymakers that are seeking to promote the market for electric vehicles. It also broadens the scope and offers important contributions to scholarly debates on the diffusion and adoption of such vehicles.

Electric Car

The beginning of 21th century is extremely important for developed countries because of the reduction of their dependence on fossil fuels. The biggest vehicle manufacturing companies are planning to start selling at least one model of electric vehicle and it is expected that by 2025 approximately 10% of the new cars sold worldwide will be electric. In order to reach this goal, some countries are successfully executing an effective electric transport development policy: to create a publicly accessible network for charging electric vehicles, pay incentives for purchasing an electric car, create free of charge parking places and implement other encouraging measures. While analysing world trends it has been noted that the majority of electric cars owners live in private houses. This is due to the fact that people who are living in apartment buildings and planning on purchasing an electric car come across multiple issues when it comes to charging the car at their living area at night. Therefore, the aim of this article is to evaluate the opportunities of developing access points for charging electric cars around the territory of apartment buildings. To achieve this we have raised these main objectives: have the EU member states already foreseen the necessary measures ensuring comfortable charging of electric cars in the territory of apartment buildings?; have the plans for the development of charging facilities in the territory of apartment buildings already been prepared?; which new technologies will be used for the safe charging of electric cars?

This article focuses on the introduction of electric vehicles in Norway and how electrical cars are understood culturally in relation to conventional car use. Theoretically, elements of social practice theory and the analysis of processes of domestication are combined to frame practical, cognitive, and symbolic dimensions of electric car use. The empirical data consists of individual and focus group interviews with electric car users. The analysis unpacks the implications of user-designated meaning in driving practices, competencies considered necessary when driving electric cars, and the material aspects regarded as critical features of electric car driving. Preliminary findings suggest that the practice of electric car driving alters user habits by making transportation needs more salient and raises both the technological and energy consumption awareness of users.

The trend of using electric vehicles is changing the automotive industry. Electric cars are becoming the most environmentally friendly replacement for combustion vehicles. Knowing the preferences of potential consumers will allow developing effective solutions to create demand for this product. Generating demand should be based on estimating its potential and shaping the consumer profile of this type of transport for market of each country. New goods need special methods to generate demand, since their potential buyers have difficulties in purchase decision making. This paper presents results of a study on prospects in Russia for such new goods as electric vehicles. The study identified factors that ultimately determine the interest of those Russian consumers who have the financial ability to purchase electric vehicles in the near future in electric vehicles. The study demonstrates that consumer prejudices are still there against difficulties in operating electric vehicles. The study confirmed that a number of factors affect the purchase of an electric car in Russia. Expanding the presence of electric vehicles in carsharing companies will significantly improve experience in using this type of transport by potential users. Generating the demand for electric vehicles by applying influence marketing tools is the one of the best solutions.

The goal of this study is to add to the understanding of the overall emissions caused by cars using both gasoline and existing alternative fuels. We will include the emission from the vehicle itself and also from upstream sources, primarily the source of the energy used to actually move the vehicle. The fact that electric motors have better efficiencies than internal combustion engines and the fact that power plants usually have higher thermal efficiencies than an engine seems to suggest that that the electric vehicle will be the more efficient in terms of emissions per vehicle kilometer. The complexities of vehicle propulsion become evident when one compares all the details of the available options, such as electric vehicles have to transport extra weight in batteries to increase performance. In this work we evaluate the emissions from electric and gasoline vehicles that are on the road. The data shows under most conditions the current vehicles have lower emissions than gasoline cars in terms of kilograms of carbon dioxide per kilometer. The different propulsion systems are then evaluated in how they would perform in moving a standardized vehicle including the system itself through a standardized cycle, to assess whether differences in emissions are the result of the system itself or other design differences. This study found that while in general the electric vehicle is better, the source of the electricity is a crucial factor in the determination. It is found that the cars currently being produced produce less green house gases than the gasoline cars on the average. In fact two of the four cars performed better even at the highest possible emission levels. While this casts a positive light on the electric car, it is a simplistic way of looking at the data. The calculations also show that the performance levels of the gasoline cars are much higher than the electric cars; this could be the main reason for the lower emissions of electric cars. The second part of this study is focused on quantifying the differences in emissions by studying that from a standardized car in all 50 states and D.C. These differences arise from the different levels of emissions owing to the variety of combinations of methods used and the methods themselves in the generation of electricity within the 51 regions. An analysis is done on of the most efficient car that could be made with commercially available products. The results show the dependence of actual emission on the energy source. Although the national, California, Florida and lowest averages all beat the performance of the gasoline vehicle, the gasoline car won if the electric car was operated in D.C. using electricity generated in the D.C. Results for the electric car in all 51 regions and for the gasoline car have been obtained. There is an implication that lower specific power would result in more states where electric vehicles will emit more green house gases. Assuming that new cars do use the higher specific power batteries, electric vehicles will produce less green house gases than gasoline vehicles at a national level.

Pollution of the environment is currently a global concern. Toxic emission from internal combustion engines is one of the primary air pollutants. In order to mitigate the effects of fossil fuel emission and address environmental concerns (ECs), electric vehicles (EVs) are being promoted aggressively all over the world. Various governments are encouraging people to switch to EVs by incentivizing the transition. Previous studies indicate that the high cost of the electric car, non-availability of charging infrastructure, time and range anxiety act as impediments to consumer adoption. The Government of India has given a call for ‘only Electric Vehicles’ on Road by 2030. This article is contemporary and examines the different factors that affect a consumer’s adoption of an EV. The respondents of the study are existing car owners in India. The data were analysed using Structured Equation Modelling (SEM). Attitude (ATT) emerged as a strong mediator, influencing the adoption of electric cars.
