EPA eGRID (regional grid carbon intensity)
The annual-average CO2e/MWh rate for the 27 eGRID subregions covering the continental US, Alaska, Hawaii and Puerto Rico -- the input behind the "and Y kg of CO2 a year" line next to a cost figure.

Worth knowing
- eGRID publishes a yearly average subregion rate, not an hourly or marginal one -- this site never places that number next to a time-of-use tariff figure, which would be a different measurement wearing the same units.
