    "additionalInfo": "Raw data on energy consumption is sourced from the BP Statistical Review of World Energy, available at:\nhttps://www.bp.com/en/global/corporate/energy-economics/statistical-review-of-world-energy.html\n\nBP's definitions of regions sometimes differ from Our World in Data's definitions.\nFor example, BP's North America includes only Canada, Mexico and United States, whereas Our World in Data's North\nAmerica includes countries in Central America (see a map with\n[our region definitions](https://ourworldindata.org/world-region-map-definitions)).\nFor this reason, we include in the dataset regions like \"North America (BP)\" to refer to BP's original data using\ntheir definition of the region, as well as \"North America\", which is data aggregated by Our World in Data using our\ndefinition.\nThese aggregates are constructed by adding up (when possible) the contributions from the countries in the region.\n\nPrimary energy in exajoules (EJ) has been converted to TWh by Our World in Data based on a conversion factor of\n1,000,000 / 3,600 (~277.778).\n\nFor non-fossil based electricity sources (nuclear, hydro, wind, solar, geothermal, biomass in power, and other\nrenewable sources), BP's generation (in TWh) corresponds to gross generation and not accounting for cross-border\nelectricity supply.\nAlso, for non-fossil based electricity, there are two ways to define primary energy:\n* One is \"direct primary energy\", which correspond to the electricity generation (in TWh).\n* The other is \"input-equivalent primary energy\" (also called \"primary energy using the substitution method\").\n  This is the amount of fuel that would be required by thermal power stations to generate the reported electricity,\n  as explained in\n  [their methodology document](https://www.bp.com/content/dam/bp/business-sites/en/global/corporate/pdfs/energy-economics/statistical-review/bp-stats-review-2022-methodology.pdf).\n  For example, if a country's nuclear power generated 100 TWh of electricity, and assuming that the efficiency of a\n  standard thermal power plant is 38%, the input equivalent primary energy for this country would be\n  100/0.38 = 263 TWh = 0.95 EJ.\n  This input-equivalent primary energy takes account of the inefficiencies in fossil fuel production and provides a better\n  approximation of each source's share of \"final energy\" consumption.\n\nAdditional metrics have been calculated by Our World in Data:\n\u2013 Annual change in energy consumption by source: this is calculated as the difference from the previous year.\n\u2013 % of total primary energy: calculated as each source's share of primary energy (direct energy and primary energy\n  using the substitution method) from all sources.\n\u2013 Per capita energy by source: calculated as primary energy consumption by source, divided by population.\n\nPer capita figures have been calculated using a population dataset that is built and maintained by Our World in\nData, based on different sources:\nhttps://ourworldindata.org/population-sources\n",
