Adjust energy prices for inflation

Start with the inflation rate formula:

CPI in 1998 / CPI in 1997 * 1997 USD value = 1998 USD value

Then plug in historical CPI values from above. The CPI for Energy was 111.515 in the year 1997 and 102.877 in 1998:

102.877 / 111.515 * $100 = $92.25

Therefore, according to U.S. Bureau of Labor Statistics, $100 in 1997 has the same "purchasing power" as $92.25 in 1998 (in the CPI category of Energy).
