Electric vehicles are growing rapidly but still make up a small fraction of vehicles globally. In 2016 there were over 2 million electric vehicles sold, with China and the US making up 60% of sales. Several automakers have announced ambitious targets to increase electric vehicle production in the coming years. Factors like falling battery prices, increasing battery energy density and renewable energy use have driven more interest in electric vehicles. Countries provide various financial incentives like tax exemptions and subsidies to promote electric vehicle adoption. Researchers in India are calling for a long term roadmap including policy support, charging infrastructure development and boosting local electric vehicle manufacturing through duty changes and investment in battery and component production.
