Annual totals and CO₂ rate reported by EPA eGRID for 2023. Reference averages are approximate U.S.-wide figures from the same dataset.
Oil-fired plants typically run only during peak demand or grid emergencies because oil is expensive compared to gas and coal. They have the highest CO₂ emissions per MWh of any common generation technology.
