Points of comparison

Internal Combustion Engine

Electric Motors

1.

Pollution

Internal combustion engines (ICEs) produce air pollution due to incomplete combustion of fuel. Other than exhaling major amount of Carbon Dioxide (CO2), some amount of nitrogen oxide and sulphur plus some hydrocarbons that are not combusted completely and they emit water and soot.

If we can have three lakh electric vehicles (EVs) on the roads by 220 including three wheelers, cars and scooters, we would have reduced pollution by 16 lakh metric tonnes.

2.

Engine efficiency
