A green vehicle is not green in color, per se. It is a common buzz-phrase that is used to refer to the type of cars that makes use of little to no conventional fuels such as gasoline. Due to them using no gasoline whatsoever, there is no excess in carbon emission that will deliver a significantly dangerous effect (s) to the environment in which the car is used at the moment. A car running on conventional fuel, on the other hand, emits carbon prints that have long been the source of environmental hazards. Depleting ozone layer on the atmosphere can be a great example of the detrimental effects of use of gasoline.

However, the primary reason as to why green vehicle is a concept widely accepted today is because the world is running out of fossil fuels and there is literally nothing to do about replenishing this resource. Experts then came up with different ways of fueling a vehicle through the use of alternative fuels. However, there are claims that state that even though a vehicle of green technology uses minimum or no amount of hydrocarbon fuel, it is still not a clear solution to put an end to fuel crises and all environmental threats.

A green vehicle takes so much effort and money to manufacture. Shipping the vehicles to any dealers in the world even often employs the kind of means of transportation that consumes even larger amount of fossil fuels in the first place. Alternative fuels used in green cars include electricity and fuel cell, hybrid electricity, compressed air, stirling, solar power, ethanol-mixed gasoline, and wind power. Recently, there has been a development in manufacturing of green cars that are operated through pedals, which work in a way someone is riding a bicycle, that are combined with electricity.
