​​Geoenergy is energy derived from the earth (including fossil fuels). Geothermal energy – heat generated or stored within the earth – is a renewable geoenergy. The geoenergy topic also includes the energy technologies that interact with the subsurface, and includes carbon capture and storage (CCS).

Geological Survey Ireland produces maps, reports and user guides for shallow geothermal energy, and carbon capture and storage. Our sister division, Petroleum Affairs Division, regulates offshore and on-shore hydrocarbon resources.
