There’s electricity in the air! But it’s not for sale

The production of electricity is outpacing sales

If you follow the energy sector, you know we’re living through interesting times. Energy sources are going through a slow but steady transformation: from traditional fossil fuels such as oil and coal to natural gas, wind, and sun. Given these changes, new companies are entering the energy production industry.

The graph above shows that electricity production in the United States has steadily grown; and, about 10 years ago, it plateaued. Electricity sales, however, have barely increased in the past decades. What’s happening? The divergence between the two measures is, to a large extent, due to more and more electricity production never hitting the market. Many firms and even households produce their own energy for their own use. This could be energy extraction from byproducts of production such as biogas or burning waste or running one’s own wind or solar farm. The recent flattening of electricity production reflects the fact that electricity demand is not increasing as it has in the past, thanks to improved energy efficiency all around. A major reason is also that the U.S. economy continues its natural evolution from energy-intensive heavy industry toward more specialized energy-efficient manufacturing and services.

How this graph was created: Search for “industrial production electricity,” select the two series, and click “Add to Graph.” From the “Edit Graph” menu, choose units “Index,” which should default to the starting date of 1972-01-01. Then click on “Apply to all.”

The cost of owing

How rising interest rates can affect the federal government's debt payments

Rising interest rates mean higher interest rates on debt payments, which means it becomes more expensive to buy a home, buy a car, or even go to college. It also becomes more expensive for the federal government to finance its debt.

As interest rates rise, payments on federal government debt also increase. The FRED graph above shows federal government expenditures with interest payments since January 1990: As federal debt has risen, expenditures on interest payments have also risen. These expenditures also depend on interest rate movements: When interest rates fall, payments decrease for the same level of federal debt. The Federal Reserve tends to lower interest rates during recessions, and this translates to lower payments, as seen in 2001 and 2008. (The gray shaded bars represent recession periods.)

Conversely, when economic conditions improve, the Federal Reserve tends to raise interest rates and this leads to higher interest payments. The second graph illustrates these two forces behind the movements in federal interest payments: The blue line is the secondary market rate on the 3-month Treasury bill, a measure of the federal government cost of borrowing that tracks very closely the interest rate set by the Federal Reserve (the federal funds rate). The red line is a measure of total public debt.

In principle, these two series can help us disentangle the main driving forces behind increasing interest payments. But doing this is more complicated than it sounds: The reason is that the federal government issues debt at different maturities, and the Fed typically sets only short-term rates. The behavior of interest rates at longer maturities depends on market forces and expectations of future inflation, among other factors.

How these graphs were created: For the first graph, search for and select “federal government expenditures: interest payments”; set the starting date to 1990-01-01. For the second graph, search for and select “3-month treasury bill: secondary market rate” (the monthly series); set the starting date to 1990-01-01. From the “Edit Graph” menu, select “Add Line.” Search for “federal debt: total public debt” and click on “Add data series.” From the “Edit Lines” tab, under “Units,” select “Index (Scale value 100 for chosen date)” and set that date to 1990-01-01. Then, under “Customize data” in the “Formula” field, type “a/100” and click “Apply.”

Is the U.S. becoming less charitable?

A brief analysis of tax returns

One may not feel very charitable while filing a tax return, but FRED data can at least help you understand something about charity in this country. The Internal Revenue Service provides some interesting statistics on how tax returns use various line items. The graph above shows two line items that can be linked to charity.

The first is deductible charitable contributions, which have declined since the mid 2000s, despite an increase along the way. Not everyone, though, can take advantage of these deductions, as taking standard deductions may be more advantageous. The second line item is the check box that asks whether you want to contribute a few dollars to the presidential election campaign. That item has been on an even more precipitous decline, independent of the political flavor of the president in office at the time. But with a little more than 4% of returns currently opting to make that contribution, this isn’t likely to be a meaningful indicator of philanthropic spirit.

How this graph was created: Search FRED for “tax returns”—which will provide plenty of interesting choices. Check the ones you want and click on “Add to Graph.”
