Keeping an Eye on Energy Prices with Wolfram|Alpha

November 5, 2010 —
Comments Off

As temperatures start falling across the U.S., many of us are looking more closely at our home heating and energy bills, wondering how much they might go up this winter. Wolfram|Alpha can’t yet predict the future, but now it can help you explore historical and recent energy-price trends in most U.S. states, thanks to data from the U.S. Energy Information Administration (EIA).

Ask Wolfram|Alpha about “heating oil prices in New Yorkโ€, for example, and you’ll see that as of November 1, the statewide average price was about $3 per gallon—slightly higher than at the start of last winter, but quite a bit below the peak in late winter of 2008. Propane prices are also higher than a year ago, and you can also see that prices climbed dramatically over the course of last winter. You can keep checking back over the course of the season to see which way prices are trending in your state.

(Note that the jagged appearance of heating oil and propane plots is due to the fact that prices are only reported for part of the year; these prices are also reported for only about 20, mostly northern, U.S. states.)

You can also ask Wolfram|Alpha about natural gas and electricity prices. The EIA keeps these figures less up to date than figures for heating oil and propane, but you can clearly see long-term price trends and seasonal fluctuations for both of them.

Wolfram|Alpha can also use this raw information to compute prices for any arbitrary amount of electricity or other fuel type. Try asking for the “price of 150 kWh of electricity in Nevadaโ€, for example, or the “average cost of 20 gallons of propane in Vermontโ€.

How are energy prices faring in your area? Are you taking any specific measures to keep your energy bills down this winter?


Neat, but I think there may be a parser bug.

When I replace Vermont with Texas I get one Texas rate listed and two Wisconsin rates -!

    David, Thank you for bringing this to our attention. Our team is working to resolve this. In the mean time we’ve updated the post with a better example. Thank you.

      But the problem is still not solved… =)

Greetings, I wonder if Six Sigma can be applied in mathematica, to describe processes.

“EIA” is simply a misprint, not a kind of new notion or service in W|A?

    Hi gorod1277, “EIA” is an acronym for the U.S. Energy Information Administration. Thank you.

      Hi, Wolfram|Alpha Team,

      Thank you very much for explanatains. My false. I am sorry.

      Reading the article I was sure that the phrase “The EIA keeps these figures less up to date” means “W|A keeps ….”. The reason was that I am very far from checking electricity price, making medical calculations etc. using W|A, while any new W|A services in applications to maths and physics are quite interesting (for me)…
