What is Geothermal Energy?

Geothermal energy is deep underground in hot rocks and water. Geothermal is an attractive resource because it provides constant baseload power 365 days a year, 24/7.

To harness geothermal energy, heat is transferred through water and steam flowing through porous rock. If the flow rate is high enough, the heat resource can be drawn to the surface through a well.

Once the geothermal brine is brought to the surface, the heat is extracted to generate electricity through a power plant or used as direct heat. Applications of direct use heat can include agriculture production, heating buildings, or tourism. Utilizing the excess heat is especially beneficial in Northern climates.
