The path beyond petroleum begins by considering five principles: that alternative sources of energy are insufficient; that hydrocarbons, metals, and electricity are inseparable; that advanced technology is part of the problem, not part of the solution; that post-oil agriculture means a smaller population; and that the basis of the problem is psychological, not technological.
Everything in modern industrial society is dependent on oil and other hydrocarbons. From these we get gasoline, heating fuel, fertilizer, pesticides, lubricants, plastic, paint, synthetic fabrics, asphalt, pharmaceuticals, and many other things. Speaking in more general terms, we can say that we are dependent on hydrocarbons for manufacture, for transportation, for agriculture, for mining, and for electricity. The peak of world oil production is (or was) about 30 billion barrels a year, supporting a human population of nearly 7 billion. In the entire world, there are perhaps a trillion barrels of oil left to extract
1: Alternative Sources of Energy Are Insufficient
Alternative sources of energy will never be of much use, mainly because of the problem of “net energy”: the amount of energy output from alternative sources is not sufficiently greater than the amount of energy input (which is hydrocarbons). Alternative sources are not sufficient to supply the annual needs of “industrial society” as the term is generally understood.
The use of unconventional oil (tar sands, shale deposits, heavy oil) poses several problems. The first is that of insufficient net energy. The second is that of extreme pollution. The third is that is even if we optimistically assume that about 700 billion barrels of unconventional oil could be produced, that amount would equal only about 15 years of global oil demand.
