It explains the energy expensiveness of modern civilization. Here are a few interesting facts it states.
About 10 calories of fossil fuel energy are used to produce every calorie of food energy in the industrialized world. This includes all of the energy to produce the food, package it, and transport it, but this does not include the amount of energy to cook the food at home.
The construction of an electronic device consumes about 10 times its own weight in fossil fuels. For example, the average computer weighs about 5 to 10 lbs meaning 50 to 100 lbs of oil is used to construct the average desktop computer. That is about equivalent to 1/2 to 1 barrel of oil to construct the average laptop or desktop computer. It takes about 1/10th to 1/20th the amount of energy to construct a desktop computer compared to a car.
It takes around 30 barrels of oil, on average, to construct a car designed for carrying 5 people. The construction of a car consumes about twice as much oil as the weight of the car.
Virtually all technology invented since the 1860s is dependent on oil in someway, shape or form. Virtually all of the products you own, bought or use were constructed using fossil fuels, especially oil. Virtually everything manufactured nowadays is made of petroleum ranging from computers (and other hi tech devices), plastics, tires, shoes, clothing, cosmetics, cars (and other transportation devices), food, pesticides, toothpaste/ toothbrushes, and the list goes on and on.
Even implementing alternative energies to oil is dependent on oil. The construction of wind turbines, solar panels, nuclear reactors, hydroelectric dams, nuclear fusion reactors, coal/natural gas extraction, biofuel production and etc all require oil.
In other words, oil is ubiquitous. It is everywhere and in everything.
By the way, I found this article by searching the following phrase on Google: " the construction of a computer consumes 10 times its own weight in fossil fuels". There is a wealth of information on the Internet, which is again a derivative of oil since all of the web servers used to maintain the internet come from countless computers that required an enormous amount of oil to construct. Also, about 10% of all electricity usage in the USA is used for maintaining the Internet, and most of that electricity was produced via fossil fuels, primarily natural gas and coal. So yes, virtually all modern technology are derivatives of petroleum.
Like Matt Savinar once said, " I don't care if you worship Jesus, Buddha or Allah. What you actually worship is petroleum". Denying the enormity and scale of peak oil is as foolish as denying the world is round. You are overly optimistic and foolish to think that peak oil can be resolved via wishful thinking. Most people think that peak oil can be resolved via some magical alternative energy, which is just silly, delusional, wishful thinking. Most people are delusional and foolish when it comes to peak oil as a result. But very few people are truly aware of the severity of the implications of peak oil, which is understandable because peak oil is rarely mentioned by mainstream media.
Very few people realize the fact that no alternative energy by itself or in any combination will be able to replace fossil fuels. That is a fact. Like Michael Ruppert once said "there is nothing in any combination anywhere that can replace the edifice built by fossil fuels". And he is quiet correct. Most modern technology simply cannot exist without abundant oil.
The obvious, unavoidable conclusion, is that peak oil will lead to the collapse of industrial civilization. And since there exists 7 billion plus people only because of oil, it is axiomatic if you take the oil away the population must go away also. I think peak oil leading to a population collapse is almost certainly going to happen. Oil is the only reason the human population breaked the 2 billion people milestone, so if you take the oil away, it is inevitable the population bubble will explode, and the population will contract back to what it was before the oil age, which was under 2 billion people.
