A REVIEW ON EVOLUTION OF HYBRID AND ELECTRIC VEHICLE

Vehicles have been around for more than 100 years. They have changed a lot in that time. Today’s cars are faster and more reliable than those of long ago. They are also safer and more comfortable. One thing has not changed: the way most cars work. Most cars of the past ran on fuel made from oil. That’s still true today. Usually the fuel is gasoline (often called “gas” for short). Sometimes it is diesel fuel. Both come from oil. The Trouble with Oil is a very good source of energy, but using it has problems. One problem is that oil is not a renewable resource. Once it’s used, it’s gone. If people keep on using it, eventually the world will run out of oil. Another problem is that using fuels made from oil releases certain gases into the air. Some of these gases can be bad for people’s health. Many scientists say that some of the gases are changing Earth’s climate. These are serious problems because the world has a huge number of vehicles, and every year more are produced. In year 2013more than 70 million cars were made. If you include trucks and buses, the number of new vehicles made that year gets even bigger. One way to deal with these problems is to use less oil. This is where “HYBRID Vehicle” comes in use. They get their power from electricity as well as from gasoline (or diesel).
