Energy systems – the production and use of fuels and electricity – are under intense pressure to change for the good of the environment and the economy. However, the flow of energy through these systems is not the problem. Rather it is the flow of carbon, especially when those flows bring carbon dioxide (CO2) and methane (CH4) to the atmosphere where they become greenhouse gases (GHGs).
Six months ago, CESAR released Sankey diagrams for Canada showing how energy flows from the sources we extract from nature, to the demands of society for fuels and electricity. Today, we are pleased to release a new set of Sankey visualizations – the first of their kind – showing how carbon flows through the same fuel and electricity systems.
