What energy costs an American household, as one number

The US Energy Index blends the four prices a household actually pays for energy — gasoline at the pump, electricity at the meter, piped gas and heating oil — into a single monthly figure, weighted by what households actually spend on each. Rules-based, computed from public BLS price data, base 2000 = 100. The figure, the weights, the source, the month. You draw the conclusion.

Weights are the 2024 Consumer Expenditure Survey annual dollars per household, normalized. The weight is what makes the blend honest: gasoline moves the index almost twice as hard as electricity because households spend almost twice as much on it.
