The Consumer Price Index was published last Thursday for May 2016. Electricity? The CPI for electricity has fallen 1.3 percent over the twelve months ending May.

During the same period, the overall CPI has risen 1 percent. So electricity is significantly less expensive than it was a year ago.

The spread between the overall CPI and the CPI-Electricity is a measure of electricity becoming less expensive. The spread for May was 2.3 percent.

The spread is computed by subtracting the overall CPI, at 1 percent, less the CPI-Electricity, at minus 1.3 percent.

In 1932, in the depths of the great depression, Owen Young was considered by many to be the favorite to be elected the nation's next president. The chairman of General Electric, GE, and the Radio Corporation of America, RCA, was famous and admired for his many accomplishments in business and public service. 

While Owen Young was chairman of General Electric, GE, he founded and chaired the Radio Corporation of America, RCA. So he headed the leading company in two of the country's top industries, electricity and communications. 

Incidentally, he also helped found the National Broadcasting Company, NBC. And, as we'll touch on below, he helped found Public Utilities Reports, the publisher of Public Utilities Fortnightly.

But Time magazine named him Man of the Year in 1930 for something else. 

In the first quarter of 2016, electricity sales to residential customers were 346.8 million megawatt-hours. This was well below sales in the first quarter of 2015. And well below sales in first quarter of 2014.

Q1 2016 sales were 8.3 percent below sales in Q1 2015. And they were 10.9 percent below sales in Q1 2014. 

Sales in March, the last month of the quarter, were particularly low. They were 14.4 percent below March 2015. And 12.4 percent below March 2014.

Last week the Commerce Department published its estimate of the Gross Domestic Product through April. And the numerous components of the GDP. 

Including consumer expenditures on everything from window coverings to spirits to flowers, seeds, potted plants to lotteries to dentists to ... electricity.

In April, consumption expenditures totaled 12,645.7 billion dollars, on an annual basis. About 12.7 trillion. 

Expenditures on electricity were 177.6 billion dollars, again annualized. About 0.2 trillion.

To whet your appetite for the June issue of PUF, here are three excerpts from my interview with Jim Fama, on his last day before retiring as EEI's vice pres. for transmission and distribution. An amazing career.

"Disney World was one of our partial requirements customers [at Florida Power Corp.]. 

One of my very first trips over there, I went to Epcot for a contract negotiation. Every one of their guys had a Disney 'My name is Bob' badge. 

On June 14, 1736, Charles-Augustin de Coulomb was born in France.

The name might seem vaguely familiar. In an electrical engineering or physics class that you struggled to keep awake in, the prof defined the unit of electric charge.

The coulomb, or just C, is the unit of electric charge. It is the charge transported by a constant electrical current of one ampere in one second.

C comes into plays in capacitance, the storing of charge. C is also the amount of excess charge on a capacitor of one farad charged to a potential difference of one volt.
