As this column has pointed out a few times in the past, hydrocarbons have been the material foundation on which continuous and limitless economic growth – so characteristic of our industrial societies – is based. It may be useful to recap the main points before we move further.
Hydrocarbons provide concentrated energy in small packets. One litre of petroleum concentrates the energy from 23 tonnes of prehistoric plant matter. Coal, though less energy efficient, is still far superior to charcoal or fresh wood as an energy source. Not only do these hydrocarbons provide high levels of energy, being carbon-based, they are useful for a range of other products for our use like fertilisers, plastics, textiles, medicines and cosmetics, among others. Further, hydrocarbons are easily transportable and storable over time, while at the same time being available in sufficient quantities for globally pervasive, if unequal, use for a few centuries before they run out.
