Welcome to GEM.wiki, a project of Global Energy Monitor. This open-access platform tracks thousands of energy projects across the globe, giving researchers, journalists, businesses, and advocates the tools to see what’s built, what’s planned, and what it all means.

About Global Energy Monitor

Global Energy Monitor is a NGO that develops and analyzes data on energy infrastructure, resources, and uses. We provide open access to information that is essential to building a sustainable energy future.

About GEM.Wiki

Global Energy Monitor provides comprehensive datasets of individual energy assets and publishes factsheets for each facility on GEM.Wiki--whether it's a coal mine, oil pipeline, solar farm, and so on.

The GEM.Wiki project is based on MediaWiki, a software platform developed by the Wikipedia Foundation that allows anyone to edit existing articles and create new ones. A key feature of wiki software is that each successive version of an article is saved along with a time stamp and a brief description of the change.

Documenting the Global Energy System

GEM.Wiki currently has information on all 27 of Global Energy Monitor's open-source datasets. The current roster of trackers is available for direct download on GEM's website:

Energy Transition

Global Integrated Power Tracker: is a multi-sector dataset of power stations and facilities worldwide.

Global Energy Transition Tracker: is an open platform of energy data and information on specific regions, or “iconic zones,” that have the potential to engage civil society in transitioning away from fossil fuels towards renewable energy.

Coal

Global Coal Plant Tracker: provides information on coal-fired power plants generating 30 megawatts (MW) and above; catalogs operating coal-fired generating units, new units proposed since 2010, and units retired since 2000.
Global Coal Mine Tracker: dataset of coal mines and proposed coal projects that includes operating mines producing 1 million tonnes per year or more, with smaller mines included at discretion.
Global Coal Terminals Tracker: dataset of import, export, and domestic coal terminals, and new projects.

Oil and Gas

Global Oil and Gas Extraction Tracker: dataset of oil and gas extraction including areas that have production of 1 million boe/yr or more and/or reserves of 25 million boe or more, or have been previously included in GOGET.
Global Oil Infrastructure Tracker: dataset of crude oil and natural gas liquids (NGL) transmission pipeline projects and their development; includes all global oil transmission pipelines and all in-development NGL transmission pipelines of pre-determined size thresholds.
Global Gas Infrastructure Tracker: dataset of natural gas transmission pipeline projects and liquified natural gas (LNG) import and export terminals; includes all LNG terminals regardless of threshold, and gas transmission pipelines over predetermined size thresholds.
Global Oil and Gas Plant Tracker: dataset of oil and gas-fired power plants; includes units with capacities of 50 MW or more (20 MW or more in the European Union and the United Kingdom).

Heavy industry

Global Iron and Steel Tracker: provides information on global crude iron and steel production plants, and includes every plant currently operating with a capacity of five hundred thousand tonnes per year (ttpa) or more of crude iron or steel.
Global Iron Ore Mines Tracker: provides information on global iron ore mines, including all operating, proposed, shelved, retired or mothballed mines since 2023.

Renewables and Other Power

Global Solar Power Tracker: documents operating utility-scale solar farms with a capacity of 1 MW or more and announced, pre-construction, construction, and shelved projects with capacities greater than 20 MW.
Global Wind Power Tracker: documents wind farm phases with capacities of 10 MW or more.
Global Geothermal Power Tracker: documents geothermal power plant units with capacities of 30 MW or more.
Global Nuclear Power Tracker: documents nuclear power plant units of any capacity and status.
Global Bioenergy Power Tracker: tracks bioenergy units with capacities of 30 MW or more at power facilities that exclusively burn biofuels.
Global Hydropower Tracker: documents hydroelectric power plants with capacities of 75 MW or more.

Energy Finance and Ownership

Global Coal Project Finance Tracker: surveys publicly- and privately-owned financial institutions that have provided funding for coal-fired power stations since 2010 or are considering funding in the future.
Private Equity Tracker: is part of a multi-organization initiative known as the Private Equity Climate Risks (PECR) project, which investigates the role of the private equity industry in the climate crisis.
Global Energy Ownership Tracker: provides information on the chain of ownership for various energy projects.

Methane

Global Methane Emitters Tracker: provides estimates of fossil fuel emissions at oil and gas and coal extraction sites, natural gas transmission pipelines, proposed projects and reserves, and attribution of remotely-sensed methane plumes.
The Gas Index: models the U.S. natural gas system to calculate life cycle methane leakage for natural gas supplies for 71 cities across the country, providing granular data on the emissions from use of natural gas.

Regional Datasets

Africa Energy Tracker: dataset of regional gas infrastructure, covering gas pipelines, LNG terminals, gas-fired power plants, and gas extraction sites in Africa.
Asia Gas Tracker: dataset of operating or in-development gas infrastructure in Asia.
Portal Energético para América Latina (Latin America Energy Portal): tracks power plants, pipelines, LNG terminals, extraction areas, coal mines, wind farms, and solar farms located in Latin America and the Caribbean.
Europe Gas Tracker: dataset of gas infrastructure (gas pipelines, LNG terminals, gas-fired power plants, and gas extraction sites) in the European Union (EU), with some components covered in non-EU countries as well.
