Adjust energy prices for inflation

Start with the inflation rate formula:

CPI in 2024 / CPI in 1979 * 1979 USD value = 2024 USD value

Then plug in historical CPI values from above. The CPI for Energy was 65.738 in the year 1979 and 277.251 in 2024:

277.251 / 65.738 * $20 = $84.35

Therefore, according to U.S. Bureau of Labor Statistics, $20 in 1979 has the same "purchasing power" as $84.35 in 2024 (in the CPI category of Energy).
