Sankey diagrams are often used to represent the flows of energy from sources (e.g. oil, gas, uranium) through commodities (e.g. gasoline, electricity) to sectorial energy demands (e.g. residential, mobility, commercial and institutional). The magnitude of the energy flow is proportional to the line thickness. Try using the options at the top of the chart to compare provinces or years, or to plot either all components of our energy systems or only the energy flows needed to meet domestic demand. You can also select whether to have the Sankey diagram display values as total energy flow (PJ), energy flows per person (GJ/capita) or energy flows per gross domestic product (MJ/$2002GDP).
We choosed to represent six end-use sectors for energy:
- Non energy: energy commodities (refined pretroleum products, natural gas etc) embedded in material such as paints, varnishes, plastics, etc.
- Personal Transport: includes personal vehicles, public transit, airplanes, etc.
- Residential: includes lighting, heating, cooking, plugloads, etc. for where people live
- Freight Transport: the movement of goods including by truck, train, ship, pipelines, etc.
- Commercial and Institutional: includes lighting, heating and cooling in all commercial and institutional buildings (warehouses, stores, office buildings, universities, schools etc)
- Industrial: the industry sectors that use (not produce) energy for manufacturing, mining, steel, cement, chemical industries, etc. In our energy Sankeys, the energy producing industry sectors are considered ‘service’ industries in the centre of the diagram that provide energy commodities such as refined petroleum production, pipelined natural gas, electricity etc. for the end use sectors.
