 So, what we defined about OPEC and non-OPEC countries, it has a big market issue because as I was mentioning that the OPEC countries with more than 80% of oil control basically the price of oil. U.S. produces, U.S. is number three producer of oil, right? But they have to import quite a bit of oil as I show you here. So, almost 50% of their oil comes from outside, where does it come from? It does not come from Saudi Arabia, it does not come from Middle East, it primarily comes from Canada. So it is not so much dependency on Saudi Arabia that people exploit politically that something has to be done about that, but that's not true. Most of the oil that U.S. imports comes from Canada, right? They do import a lot of oil from Saudi Arabia still and you will see the effect of that in terms of trade deficit in the next section, but it has a political sort of impact when you talk about the oil coming from Saudi Arabia. American production even though high, it still requires import from other countries. But what is interesting if you look a little bit about the energy trivia, trivia that means the small things about its energy, if you look at it, the barrel of oil, we will talk a lot about barrels of oil, in one barrel there is 42 gallons of crude oil. Now, when we talk about oil, we will see how it is in distillation. Now, in distillation when it goes, the 42 gallons of about 50% and less than that, oil comes out of it, that means petrol comes out, the rest of the diesel and this and that, a lot of other things come out, but it is not as valuable as the value of the petrol. So, the barrel of 42 gallons, this is very important information that should be in your mind. The most important thing is that it is in this slide. The purpose of this slide is that I will tell you how much oil is used there. Now, the world's population is now 8 billion, it is approximately 7.5 billion, but two months ago it reached 8 billion. And the US population is up to 330 million. So, you should compare the two populations. So, this means that the United States is only 4.4% world population, 4.4%. Let's say 5% of the whole population. The world's oil production is 82.5 million barrels per day. And the oil consumption of the United States is 20.7 million barrels per day. So, you should compare it, that means the world's oil consumption is 25% in the US. Now, you see, the population of 5% is using 25% of the oil. So, these are not global resources, right? So, as I talked to you, it is okay if you use it, and if you don't use it, there is no problem if there is no environmental effect. But the more you use it, the more the environmental effect will be. So, this is why we should keep in mind where the pollution is coming from. China's consumption is very minimal, according to the United States. Although, they use so much coal. And, of course, locally, they have a very big environmental problem. And that problem actually extends out of China also into the neighboring countries because all of those get the fumes, get the carbon dioxide coming out of China. So, China has something to be blamed for. But it is not as big a problem as the big problem comes from America, that they are using 25% of the oil, only 5% for the population.
