What is Geothermal Energy?
Geothermal energy harnesses heat from the vast natural furnace inside the Earth. The core of the Earth is about the same temperature as the sun's surface, and the heat is continually replenished by the decay of radioactive elements that are mostly concentrated in the Earth’s crustal rocks, providing a huge source of sustainable and virtually emission-free energy.

How is Geothermal Energy used?
Ground Source Heat Pumps
Ground-source heat pumps (also known as geothermal heat pumps) are one of the most energy-efficient technologies for space heating and cooling and water heating. They work much like the reverse cycle heating and cooling systems commonly used throughout Australia but take advantage of the relatively constant temperatures present in the ground down to a depth of about ~50m. This allows the heat pump to operate more efficiently, thereby substantially reducing energy use.
Why should you become an AGA Member?
Service providers can be included in our Member Services database by becoming a Professional Member. AGA does not advocate or promote any particular Member Services in preference to others.
Our Member Services database guides and assists the public to search for a service or geothermal equipment provider or a consultant to undertake a geothermal project.

What is Geothermal Energy?Geothermal energy (from Greek roots geo, meaning earth, and thermos, meaning heat) comes from the core of the Earth, which is about the same temperature as the surface of the sun. Heat from this vast natural internal furnace constantly flows towards the surface, supplemented by heat from radioactive decay of elements like uranium, thorium and potassium that occur commonly in the mantle and continental crust. Taken together, this geothermal energy represents a huge source of emission free energy.
What is the Australian Geothermal Association (AGA)?AGA is the peak organisation for Geothermal Energy in Australia. Incorporated in 2016, the Australian Geothermal Association (AGA) is a professional society whose members are individuals working in industry, academia and government, representing the full range of geothermal applications from ground source heat pumps to direct industrial heat supply, recreational bathing and wellness, and electrical power generation.
Is the AGA not-for-profit?AGA is not-for-profit, non-party political and non-sectarian.
What is the mission of the AGA?The AGA was incorporated to promote the science, technology and development of Geothermal Energy.
