Thus, using a car powered by fuel cells would be the most efficient action for the individuals to take in order to minimize emissions of greenhouse gases.  

The fuel cells are specific in terms of the array of their potential uses, as they can offer power for the systems as big as a utility power station, and as small as a computer. The fuel cells have an application in various things, which comprises material handling, transportation, emergency back-up power applications, and others.
