Hydrogen is a not a fuel source, but a fuel carrier
Surprisingly, hybrid cars were around even before gas-powered cars. Back in about the year 1665, a Jesuit priest by the name of Ferdinand Verbeist began plans for a certain type of vehicle. That vehicle would be very simple, nothing complex, or intricate. Simple was all he wanted. So Ferdinand planned out a car that would have four wheels and would run only on steam. It took about fifteen years of work for Ferdinand to go through with his plan. He labored to perfect his dream car. But no one knows if he ever finished because there is no evidence that his concept existed.
Well, because hybrid cars use much less fuel than other cars, they help to keep the air squeaky clean. Therefore, everyone can breathe a little easier when a frequent driver decides to buy a hybrid car. Other cars add to the deterioration of our ozone layer. But with hybrid cars, that's not necessarily the case.
Because hybrid cars have a complex internal design, they can have a pretty hefty price tag. On the other hand, conventional cars, which have probably gotten more efficient in design as the years have gone on, are quite affordable these days. Many people can be seen selling their old conventional cars. Some people even give these types of cars away. However, since a large percentage of the general population has never owned a hybrid, there aren't many people selling used hybrid cars. Therefore, the average person looking to buy a hybrid would probably have to purchase one from a car dealer.
