Do we need petrol to run our cars?

In the majority of cases, yes, petrol (also known as gasoline) is needed to run cars with internal combustion engines, which are the most common type of engine used in cars today. However, there are alternative fuels and technologies that can be used to power cars, such as electric vehicles, hybrid vehicles, and biofuels. Electric vehicles run on electricity stored in batteries, hybrid vehicles combine an internal combustion engine with an electric motor, and biofuels are made from renewable resources such as plants or algae.
