Key insights

  • 51% of coal is used for Total Electricity Generation (38% direct Electricity Generation + 13% Cogeneration)
  • 29% of coal is consumed for Industrial use

NOTE: We could not find good definitions or detailed explanations of Other Transformation (16%), but will update this page once we have it.

Key questions

  • Burning coal for electricity generation rapidly declined from a high in 2005 to a low in 2016, so why has it rapidly increased again?
  • How do we reduce our electricity consumption, or increase cleaner electricity production?
  • Why has cogeneration (recycling the heat produced in an industrial process and turning it into electricity) not increased in the last 2 decades?

Notes

  • All publicly available data has been included.
  • We decided to show coal data in tonnes rather than PJ (Petajoules) as this is an easier concept for most people to understand.
  • We have shown full-year data only due to the seasonality of both coal use and electricity generation.
  • There is a good summary of the types of coal on https://www.eia.gov/energyexplained/coal/.
  • Once we receive/find more information on Other Transformation, we will update this page.
  • All numbers are provisional and subject to revision.

Thank you to the Factors who helped pull this together.
