Global Energy Monitor (GEM) provides a transparent, free collection of datasets designed as an open guide to the world’s energy system. The data covers global energy supply chains and infrastructure through multiple trackers, including coal plants, coal mines and terminals, gas finance and infrastructure, oil and gas extraction, infrastructure and processing plants, and methane emitters, as well as power generation assets across solar, wind, hydropower, geothermal, bioenergy, and nuclear. Additional datasets extend to energy-related industrial sectors such as iron and steel, cement and concrete, iron ore mines, and chemicals. These datasets support public accountability, research, and decision-making on energy development and the energy transition.
