Geothermal is a lesser-known type of renewable energy that uses heat from the Earth’s molten core to produce electricity.
While this unique feature gives it key benefits over solar and wind, geothermal also suffers from high costs and geographic restrictions. Because of this, few countries have managed to produce geothermal energy at scale.
In this infographic, we’ve used a combination of diagrams and charts to give you a high level overview of this sustainable energy source.
Geothermal energy is produced by accessing reservoirs of hot water that are found several miles below the Earth’s surface. In certain parts of the planet, this water naturally breaks through the surface, creating what’s known as a hot spring (or, in some cases, a geyser).
