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.
