Electric vehicles are considered as an important means to cope with increasing environmental problems in the transport sector. Many governments worldwide have set targets to increase the number of electric vehicles, although their environmental benignity is not ensured in the scope of the policies implemented. The core objective of this paper is to investigate the overall environmental impact of electric vehicles in different regions. The analysis is based on a life cycle assessment of electric vehicles including emissions from electricity generation, vehicle production and disposal, and vehicle use. The major conclusion is that the environmental benignity of electric vehicles is very sensitive on: electricity mix (a); number of km driven per year (b) and embedded emissions in car production (c), as well as battery recycling. Yet, as shown in this paper the highest sensitivity is with respect to the electricity mix. Hence, to make electric vehicles more environmentally friendly it is most important to increase the share of renewable energy sources in electricity generation.

Transportation has become an important part of our day to day life. Due to changing lifestyle, frequent travels whether related to work or leisure has become a common phenomenon. Such lifestyle also demands comfortable transport medium and reasonable availability of fuels. As need of vehicle for transportation is rising, it has put pressure of fuel supply, fuel prices and environment as well. The rising prices of fuel, increasing pressure on resources and threatening environment pollution is driving the need for alternative and clean sources of energy. Increasing competition among nations to own the resources is becoming a serious threat for many developing countries. This paper empirically examines the gender preference for alternative energy sources and related technologies for vehicles. In total, 1168 questionnaires were received from respondents (male-711, female-442, not disclosed-15) from eleven cities in India viz. Bengaluru, Chennai, Cochin, Coimbatore, Hyderabad, Pune, Imphal, Rohtak, Sagar and Tiruvanathpuram in India and one city from Bhutan-Thimpu. Respondents who did not disclose their gender were excluded from the study. The study was conducted from October 2013 to June 2014. The objective of the study was to understand the social dimensions and gender preferences of the respondents regarding their preference for electric vehicle as an alternative energy transport for personal and public use. The primary data was collected through a structured questionnaire. The data was analyzed through the Statistical Package for Social Science (SPSS ® ). Findings indicate that in general fueled vehicles are still preferred over electric vehicles. However there is a strong interest in electric vehicles. It was observed that more than 66% of the respondents in the age group of 18-30 can become prospective customers in the near future, if the electric vehicles meet their expectations. In this age group, 59% of the respondents were male and 41% were female. Most of the respondents indicated that they would purchase the electric vehicle as it would save operating costs, it is environment friendly and less dependent on fossil fuel. It was observed that as compared to female, male respondents were more inclined towards the influential factors like fuel efficiency, safety, vehicle power and reliability and early availability of vehicle in the market. In all 93% of respondents confirm that they are willing to pay the premium price and among them, 61% were male and 39% were female.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
