Geothermal Energy

Geothermal energy is a secure, environmentally sustainable, and cost-effective source of renewable energy that is growing in popularity across the world. It is defined as energy in the form of heat stored beneath the surface of the Earth. This heat can be found both near the surface and deep underground, and can be used in a wide variety of applications including space heating (and cooling), industry, agriculture and even electricity generation.

Approximately one-third of our energy demand is in the heating sector, the vast majority of which is powered by fossil fuels. Geothermal energy is a renewable, low-to-zero carbon emission resource. By tapping into our national geothermal energy resources we could replace some of these fossil fuels with a secure and sustainable heating alternative.

Geological Survey Ireland produces maps, reports and user guides on Irish geothermal resources, and provides scientific advice to policy makers and the public. The National Geothermal Database is currently in development.

The Geothermal Programme is conducted by the Groundwater & Geothermal Unit.
