CPI — Energy

## What this measures

Energy prices paid by households: gasoline and other motor fuel, heating oil, electricity and utility gas. The Bureau of Labor Statistics price index for this item for all urban consumers, U.S. city average, seasonally adjusted, with 1982-84 = 100.

## Why it matters

Energy is the most volatile part of the CPI and the part people notice first. It moves with crude oil and natural gas prices.

## How to read it

The level of an index means little on its own. Read the change from a year earlier, and compare it with overall CPI (fred_cpi) to see whether this item is running hotter or cooler than prices in general.

## What it does not say

It measures prices, not spending: if people buy less of something because it got dearer, this index does not show that. The BLS adjusts for quality changes, so it is not the same as the sticker price.
