What is the term used for steam sourced from deep Earth sources?

The term used for steam sourced from deep Earth sources is geothermal steam. Geothermal energy utilizes heat from within the Earth, which is a reliable and sustainable energy source. This heat can be harnessed to generate steam, which is then used to drive turbines for electricity production or for direct heating applications.

Geothermal steam comes from natural underground reservoirs of steam and hot water, which are tapped through wells drilled into geothermal formations. The temperature of the steam can vary widely depending on the specific geothermal resource, making it a versatile option for energy production.

In contrast, fossil fuel steam is produced by burning fossil fuels like coal, oil, or natural gas, solar steam is generated using solar energy, and nuclear steam is produced from heat generated through nuclear fission reactions. Each of these alternatives does not originate from the Earth’s internal heat but rather relies on different processes and energy sources.
