These flow charts show carbon dioxide emissions for each state, the District of Columbia and the entire United States. Emissions are distinguished by energy source and end use.
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Students can examine, compare, and evaluate the CO2 production in each state and identify renewable alternatives.
The carbon emissions are presented in a series of Sankey diagrams for the 50 states, the District of Columbia, and the nation.
Well-vetted, authoritative data showing sources and uses of energy, which can help bring a regional context to energy discussions and investigations.
Passed initial science review - expert science review pending.
Viewers can identify how different states' CO2 emissions vary and identify the energy resources contributing to the CO2 production.
Students may need some coaching in understanding the Sankey (sometimes called "spaghetti") diagrams.
PDF document can be printed off and distributed.
Diagrams are well designed.
Supporting documentation is clearly written.
