Thsesedays, many companies are manufacturing
only hybrid cars and developing them since they found it more profitable and
more attractive to buyers. They are also improving its features and trying to
use alternative power sources like hydrogen. These new cars will depend on
chemical energy by burning hydrogen itself or reacting hydrogen with oxygen.
The success of the use of hydrogen will make a revolution at all standard,
since our political, industrial and commercial life depend on the high demand
of petrol, which includes gasoline of course. The development of hydrogen power cars was
supported by both the private sector and the government. Most hydrogen cars are
currently only available as a model for testing and improvements. They are not
ready for public use yet. (Borras.2010)
According to recent and new studies,
there are about two million hybrid cars on the roads. The top five countries
that use hybrid cars are Japan, the United States, Canada, Netherlands and the
United Kingdom. In Japan and the United States, hybrid cars make up over half a
million. These numbers are not fixed or determined; everyday new markets and buyers
prefer hybrid cars over gasoline only cars which mean the number will get
bigger and bigger. (spencer.2011)
