Economic and job growth are closely tied to energy consumption. While jobs can grow faster than energy use when efficiency kicks in, the cost may be lower wages.
US Census Bureau
The number of jobs available to job-seekers has been a problem for quite a long tine now—since 2000 in the United States, and longer than that in Europe. If we look at the percentage of the US population who are employed, it is now back to 1984 or 1985 levels. (See Figure 1 above.)
I have run into a number of clues about what is happening. In this post, I’d like to discuss what I am seeing. Part of the problem is that high oil costs squeeze the economy, reducing employment. Part of the problem is growing trade with Asia. It is even possible that the Kyoto protocol (which the US did not sign) has something to do with what we are seeing. Let me start by explaining a fairly strange relationship.
A Strange Relationship – A Close Tie Between the Amount of Energy Consumed and the Number of People Employed
Since 1982, the number of people employed in the United States has tended to move in a similar pattern to the amount of energy consumed. When one increases (or decreases), the other tends to increase (or decrease). In numerical terms, R2 = .98. (Click on Figure 2 above.)
I have written recently about the close long-term relationship between energy consumption and economic growth. We know that economic growth is tied to job creation, so it stands to reason that energy consumption would be tied to job growth1. But I will have to admit that I was surprised by the closeness of the relationship for the period shown.
This close relationship is concerning, because if it holds in the future, it suggests that it will be very difficult to reduce energy consumption without a lot of unemployment. It also would seem to suggest that a shortage of energy supplies (as reflected by high prices) can lead to unemployment.
Why Rising Energy Cost (Particularly Oil) Leads to Lower Employment and Less Energy Consumption
Suppose oil prices rise2. The critical issue is that consumers’ incomes do not rise at the same time. Consumers’ budgets get squeezed, and they cut back on discretionary spending. For example, they may go out to restaurants less, make fewer long-distance vacation trips, put off buying a new car, or contribute less to their favorite charities. Workers in discretionary sectors of the economy tend to get laid off, as a result. We have come to know this as part of recession.
(The impact of an oil price rise will be worse if other fuel prices, such as natural gas, rise as well. It will be mitigated, if natural gas prices are low, as they are in 2012 in the United States. Europe has much higher natural gas prices than the United States. This is big part of the reason why recessionary impacts are now worse in Europe than the United States.)
In the case of high oil prices and lay-offs, less energy of all types–not just oil–is used. Laid-off workers may move in with relatives, and thus reduce their living expenses. Each laid-off worker would have used oil to get to their job, and this will no longer be required. The jobs experiencing layoffs themselves may have required fuel use of various types, such as heat for buildings, fuel for airplanes, or electricity used in making new cars, and this is reduced as well.
There is also likely to be a link to housing prices. Moving up to a more expensive home is a discretionary expenditure. If people’s incomes are squeezed by high oil prices, and some are being laid off, there will be less demand for homes as well. This lower demand can be expected to reduce housing prices, especially in areas where commuting distances are longest (and thus, oil use for commuting greatest). There are also likely to be layoffs in the construction industry, as there is less demand for new homes and new buildings of all sorts.
High Energy Costs in One Area Tend to Lead to Substitution to Places Where Energy Costs Are Lower
If there is a possibility of international trade, manufacturing and some types of services will tend to move to areas where costs are lowest. Part of these costs are energy costs. A manufacturer with cheap electricity costs will have an advantage over one with higher electricity costs. As energy costs rise (as they have in recent years), they get to be more important in determining where manufacturing will be done.
Besides direct energy costs, wages are another part of the difference in costs from one part of the world to another. Wages tend to be lower in the warmer areas of the world. In part, this is because energy from the sun provides much of the needed energy for heating homes, so there is less need for supplemental energy. This means that wages do not need to be as high for a comparable standard of living.
