EVs more harmful, more expensive in the long run as compared to ICE and Hybrid cars: IIT-K study

Hybrid Electric Vehicles most eco-friendly: Study

The new study conducted at IIT Kanpur compares the overall environmental impact of electric vehicles (EVs) or battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and conventional internal combustion engine (ICE) – powered cars. Professor Avinash Agarwal, who conducted the study along with a Japanese organisation, comments that a conventional ICE-powered car is cheaper than an EV while HEVs are more eco-friendly. Prof Agarwal however states that EVs could be beneficial for taxi or fleet operators.

The study was approached by dividing it into three categories – two foreign categories and one Indian category to calculate the Life Cycle Analysis (LCA) and Total Cost of Ownership (TCO) of vehicles. The study then found that BEVs emit 15-50 per cent more greenhouse gases across various different categories when compared to a conventional ICE-powered vehicle. One major contributor to this emission is the source of the electricity that is used to charge up a BEV. India derives a majority chunk of its energy from coal which contributes massively to CO2 emissions. BEVs also turn out to be 15-60 percent more expensive to run per kilometre when aspects like long-term, purchase, insurance and maintenance are factored in.

BEVs turn out to be the most harmful of all three segments of cars but are however being promoted by the government through lower taxes and other benefits to the buyers. Hybrid vehicles emit the least amount of GHGs in the comparison set and are also 1.5 to 2 times more efficient than conventional ICE cars. However, the HEVs are the most expensive of the lot and are subject to heavy taxation.
