What you should know about this indicator

How is this data described by its producer?

In this review, energy supply comprises commercially-traded fuels, including modern renewables used to generate electricity. Energy from non-fossil fuel combustible electricity generation is accounted for on their input heat requirements and non-combustible renewables on the energy content of their gross electrical output. See https://www.energyinst.org/statistical-review for more details on this methodology.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator
  • The total energy supply is extended to countries not covered by the Statistical Review using the U.S. Energy Information Administration's (EIA) total energy consumption. The Statistical Review is prioritized where both sources are available.
  • The World series is extended back to 1800 using Vaclav Smil's historical estimates (2017), for years before the Statistical Review begins (1965). Only commercially-traded energy sources are included (traditional biomass, which Smil reports but the Statistical Review does not, is excluded so the series stays on a single basis with no step at the splice).
