Methodology
US data on electricity generation, including generation, demand, net imports and capacity deployment is sourced from the US Energy Information Administration (EIA).
Generation from small-scale and distributed solar installations is included in both national and state level solar generation data. Small-scale solar data is reported by the EIA. National electricity demand values are the sum total of all generation sources (including small-scale solar) and net imports.
Ember compiles US state level data on generation as well as derived data on power emissions and emissions intensity which is used in this report. Emissions for the US total and states are calculated using the same methodology used in Ember’s yearly electricity data.
Ember’s electricity data, including the US total, is also accessible through Ember’s Electricity data explorer. US state level data is also available in Ember’s US electricity data explorer.
