There are many who believe that the use of energy is critical to the growth of the economy. In fact, I am among these people. The thing that is not as apparent is that growth in energy consumption is dependent on the growth of debt. Both energy and debt have characteristics that are close to “magic” with respect to the growth of the economy. Economic growth can only take place when growing debt (or a very close substitute, such as company stock) is available to enable the use of energy products.
The reason why debt is important is because energy products enable the creation of many kinds of capital goods, and these goods are often bought with debt. Commercial examples would include metal tools, factories, refineries, pipelines, electricity generation plants, electricity transmission lines, schools, hospitals, roads, gold coins, and commercial vehicles. Consumers also benefit because energy products allow the production of houses and apartments, automobiles, busses, and passenger trains. In a sense, the creation of these capital goods is one form of “energy profit” that is obtained from the consumption of energy.
The reason debt is needed is because while energy products can indeed produce a large “energy profit,” this energy profit is spread over many years in the future. In order to actually be able to obtain the benefit of this energy profit in a timeframe where the economy can use it, the financial system needs to bring forward some or all of the energy profit to an earlier timeframe. It is only when businesses can do this, that they have money to pay workers. This time shifting also allows businesses to earn a financial profit themselves. Governments indirectly benefit as well, because they can then tax the higher wages of workers and businesses, so that governmental services can be provided, including paved roads and good schools.
Debt and Other Promises
Clearly, if the economy were producing only items for current consumption–for example, if hunters and gatherers were only finding food to eat and sticks to burn, so that they could cook this food, then there would be no need for the time shifting function of debt. But there would likely still be a need for promises, such as, “If you will hunt for food, I will gather plant food and care for the children.” With the use of promises, it is possible to have division of labor and economies of scale. Promises allow a business to pay workers at the end of the month, instead of every day.
