The state of United States of America’s power emissions
Across the 1,179 United States of America power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 757 Mt CO₂/yr. The single largest emitter, Gavin Power LLC (coal), accounts for about 2% of that 1,179-plant reported subset (not of the whole country). The top three owners — Tennessee Valley Authority, Associated Electric Coop Inc, Monongahela Power Co — control roughly 7% of that 1,179-plant reported subset. Most of these plants sit in a temperate Köppen climate zone.
