Global Electricity Generation Map

The International Energy Agency (IEA) is an intergovernmental organization working with OECD member countries and partner economies on energy security, analysis, and statistics. Its Monthly Electricity Statistics collect timely power-sector data through the IEA monthly questionnaire — the basis for Detailed mode on this map.

The U.S. Energy Information Administration (EIA) is the U.S. Department of Energy's independent statistical agency. Its International Energy Statistics compile annual energy balances and electricity series for countries worldwide — the basis for Global mode on this map. For U.S. wholesale market and FERC tariff vocabulary (a different topic from these international statistics), see Terminology Flashcards.

The IEA's Monthly Electricity Statistics (MES) reports timely electricity production for OECD member countries and a selection of other economies. The metric shown here is net electricity production — gross generation minus auxiliary use and transformer losses at the plant — measured in gigawatt-hours (GWh).

Data are collected through the IEA's monthly questionnaire on an M-2 basis (the "MES month" lags publication by about two months). Definitions align with the IEA's annual Electricity and Heat questionnaire. OECD countries generally have history from January 2010; many partner economies from January 2015 onward.

Monthly generation statistics offer a relatively current picture of how countries produce electricity and how the mix is shifting — for example growth in wind and solar, the role of nuclear and hydro, or dependence on natural gas and other combustible fuels. Comparing countries on a common metric helps illustrate regional differences in decarbonization pace, resource endowment, and grid-scale investment, even though national reporting practices vary.

TransANCHOR aggregates twelve complete calendar months into annual totals for each country and fuel category. Partial years (for example months still being revised) are excluded. The fuel selector maps to IEA product categories such as Total, Wind, Solar, Nuclear, Hydropower, and Natural Gas.

The choropleth uses a logarithmic color scale because generation spans orders of magnitude between large and small systems. Countries without data for the selected fuel and year appear unshaded. Regional aggregates (OECD Total, IEA Total, etc.) are not shown on the map.

• Coverage (IEA mode only): Only IEA member and selected partner countries appear in Detailed mode (48 in this dataset), not a full global inventory.
• Estimates and imputations: To publish on schedule, the IEA may supplement national submissions with other sources or estimate missing series; many values in the underlying data are flagged as imputed.
• Revisions: Historic data are recalculated when annual questionnaires arrive or methodology improves; the latest IEA release should be treated as authoritative.
• Scaling: Monthly figures are adjusted proportionately to stay consistent with the most recent annual data by source.
• Country-specific gaps: Reporting varies — for example Japan's latest month may be estimated (M-3), Australia and Japan use fiscal-year adjustments, and some countries lacked solar or pumped hydro in monthly returns until secretariat estimation.
• Not operational intelligence: This map is for exploration and education; it is not a substitute for official national statistics, market data, or compliance reporting.

For 61 countries, the detail panel can show final energy consumption from the IEA Energy End-uses and Efficiency Indicators Highlights (annual snapshots in petajoules). This is demand-side data — how energy is used in buildings, industry, and transport — not net electricity production on the choropleth.

• Appears when you select any of the 61 EEI countries, in both Detailed (IEA) and Global (EIA) map modes.
• Years available: 2000, 2005, 2010, 2015–2023; if the map year is newer, demand data snap to the nearest earlier EEI year.
• Manufacturing in sector charts is the ISIC manufacturing subset — not full mining, agriculture, or construction.
• Decomposition charts use IEA LMDI methodology (log-mean Divisia index) to separate activity, structure, and efficiency drivers.

Do not compare EEI consumption directly to generation totals on the map or in the Compare sources table — units and definitions differ (PJ vs GWh; consumption vs production).

The IEA special report Energy and AI models data-centre facility electricity — server farms and digital infrastructure serving cloud, AI, and other online services. Values are in terawatt-hours (TWh) under the annex Base Case.

• Detail panel appears for the United States and China only, in both IEA and EIA map modes.
• Annex snapshots used here: 2020, 2023, 2024; if the map year differs, data snap to the nearest available year.
• Global total (Base Case): about 416 TWh in 2024 — roughly 1.5% of global electricity consumption per the report.
• Regional rows in the annex (Europe, Asia Pacific, etc.) are not mapped to individual countries on this page.

See the report chapter Energy demand from AI for methodology.

Do not compare data-centre TWh to generation GWh on the choropleth, EEI final-energy PJ, or the Compare sources table — separate modelled estimates and definitions.

U.S. Energy Information Administration (EIA) International Energy Statistics report electricity generation (billion kWh, converted to GWh here) for about 222 countries, annually from 1980 through the latest available year.

Official source: EIA International Energy Statistics. Global mode uses a separate annual dataset from Detailed (IEA) mode; switch coverage above to view it.

The United States appears as a single country on this global map. For state-by-state net electricity generation — 50 states and DC, by fuel, with monthly trends and rankings — use the dedicated U.S. State Electricity Map.

That page uses EIA Electricity bulk data (plant-level monthly surveys aggregated to complete calendar years), not the EIA International Energy Statistics shown here in Global mode. National and state totals use different scopes and should not be compared as identical figures.

Net electricity production (IEA) is generation minus plant auxiliary use and transformer losses — electricity sent toward the grid. Electricity generation (EIA) is output at the plant. Small differences between sources for the same country are expected.

• Estimates: Many EIA country-year values are modeled or estimated, not direct monthly reporting.
• Pre-2000 fossil splits: Coal, natural gas, and oil may show as unavailable (NA) before about 2000 even when Total exists.
• No monthly series here: EIA mode shows annual history only; use IEA mode for within-year seasonality.
• Pumped storage excluded: EIA pumped-storage rows can be negative consumption and are not mapped as a fuel.
