A new study from the Indian Institute of Technology (IIT) Kanpur says that Battery Electric Cars (BEVs) might not be as environmentally friendly as previously thought. The study looked at the manufacturing, usage, and disposal of electric cars, and compared the Life Cycle Analysis (LCA) and Total Cost of Ownership (TCO) of electric, hybrid, and conventional internal combustion engine cars. The findings indicate that BEVs emit 15-50 percent more greenhouse gases in different categories compared to other vehicles. This is because electric car batteries are often charged with electricity generated from coal, resulting in carbon dioxide emissions.
The study found that Hybrid Electric Vehicles (HEVs) emit the least amount of greenhouse gases and are more fuel-efficient than conventional engine cars. However, they tend to be more expensive due to high government taxes on hybrid cars. The report suggests that if the government wants to promote clean technology, hybrid cars should be taxed on par with battery electric vehicles.
Despite the environmental drawbacks, battery electric cars are being encouraged through lower taxes and other incentives for buyers. Hybrid cars offer better mileage per liter compared to conventional engine cars. Ultimately, the report suggests that for personal use, conventional engine cars are more cost-effective, while battery electric cars are more efficient for taxi operators. Hybrid vehicles are considered the most environmentally friendly option.
