U.S. State-Level Electric Power Emissions by Producer and Fuel 1990-Present

Annual U.S. state-level emissions data for Carbon Dioxide (CO2), Sulfur Dioxide (SO2), and Nitrogen Oxides (NOx) from the electric power industry, extending from 1990 to the latest available year. The dataset is organized by type of electric power producer and by energy source, based on Form EIA-861 data. It is published by the U.S. Department of Energy.

Use Cases

• Analyze trends in CO2, SO2, and NOx emissions by U.S. state and energy source to assess the impact of fuel switching policies.
• Compare emission intensities across electric power producer types, such as Electric Utility versus Industrial Cogen, for specific pollutants.
• Model the relationship between energy source categories like Coal, Natural Gas, and Petroleum and their contribution to total SO2 emissions over time.
• Build a dashboard to track state-level progress on emission reductions for NOx across the Total Electric Power Industry from 1990 onward.

Strengths

• Provides a long-term annual time series extending back to 1990, enabling longitudinal analysis of emission trends.
• Disaggregates data by multiple analytical dimensions: U.S. state, type of electric power producer, and specific energy source.
• Covers three major air pollutants (CO2, SO2, NOx) critical for environmental and climate policy analysis.
• Sourced from the authoritative U.S. Department of Energy and based on official Form EIA-861 data.

Limitations

• The dataset's last update was in July 2021, so it may not reflect the most recent years of emissions.
• Specific structural details like row count, column count, and sample data are unavailable for review.
• Data is provided in XLS format, which may require conversion for use in modern data science pipelines.
