Shallow geothermal energy – also known as ground source heat – can be used for heating and cooling buildings, offices and factories. We have produced maps and user guides to help people find out more about the resource and where to find it.

The earth's temperature increases with depth. Heat energy from deeper within the earth can be harnessed for district heating or, if hot enough, used to power electricity turbines. The IRETHERM project has increased our understanding of Ireland's geothermal energy potential.
