To take the environment into account !

Is a global increase of the world oil demand possible ? So the most important question is : how many resources are available for the future ? how much long can we even chose oil ? We know that today there is approximately 4000 gtep (gigatonne equivalent petroleum) with 3000 hypothetics gtep.
With this approximation we are safe for 4 centuries but if we consider china and it incredible growth, this resources will disappear in 50 years. So have a break and take a time to read this global point about oil issues.
Today oil is everything, with oil you can :

• drive
• fly
• have heating
• get dressed

So it's not surprising which in few decades, oil is becoming dominant in economy and industry. The first thing we think about oil is the transport field. Oil is a necessary fuel to move but it allows us to have heating or electricity .Oil is the first component to produce plastics too.

Here it is a graph which show us the oil uses in 2004:


No you can see that already in 2004,In the United States, transport uses approximately 80% of their oil resources. In France it accounts for 60%. So in both cases, it takes more than half of their oil global consumption.
A point about china which has already developed its industry (10% ).
