Researches proved that the carbon produced by cars these days is a main factor in increasing the size of the whole in the Ozone Layer which will lead in the end to Global Warming. If 2005 was the year of global Peak Oil, worldwide oil production in the year 2030 will be the same as it was in 1980. However, the world’s population in 2030 will be both much larger (approximately twice) and much more industrialized (oil-dependent) than it was in 1980. This is why the world will be looking for other sources of energy and fuel for cars and all the other machines. Car companies introduced many new technologies such as the hybrid cars and the electric cars (EV).

Hybrid Cars use an electric motor and large battery to take and store energy that is normally lost in inefficient gasoline engines. The energy is used to help run the vehicle and can dramatically improve fuel efficiency.
However, Even though hybrids are efficient, they still use oil; they are simply more efficient gasoline cars. A better solution would be Plug-in Hybrid Electric Vehicles (PHEVs). The idea is to increase the size of the battery in a normal hybrid so it can take more energy, and add a plug, so that the car can also get energy from the electrical grid or from rooftop solar power.
Another alternative for oil cars are the electrical cars that are more advanced in which they don't have a gas tank. The only power for the car is its electric motor and a very large battery pack, which is plugged in to recharge

John DeCicco, a Detroit based car expert was asked if the green cars will affect the US economy standards. DeCicco answered " I get this question a lot and the truth is that it's a very unhelpful and distracting issue. Fuel cell technology is very speculative. The challenges facing fuel cell technology make it a highly dubious proposition." [1] He also stated "This is not a technological issue. It's not about what technology is available. It's about how the technology is used." [2]
On the other hand Katsuaki Watanabe, Toyota's president, said at an environmental forum in Tokyo on June 11 "Without focusing on measures to address global warming and energy issues, there can be no future for our auto business." [3]
But DeCicco seems to have a different view; he stated that "none of the car companies are giving global warming any real consideration." [4]
So there's still a debate behind the real reason of making these kind of technology that should be environmental friendly.
