Geothermal Energy And Its Workings

The name “geothermal” can tell you a lot about this type of green energy source. It refers to the heat produced by the earth. Many countries around the world are opting for geothermal energy as a source of a clean and sustainable power.

Geothermal energy comes from a layer of the earth which contains magma that produces heat indefinitely. This heat gets mostly felt in areas where there are volcanoes that are active, or that got formed recently. Another characteristic of geothermal spots is that they have a lot of seismic movements that lead to the formation of geysers and hot springs.

Tapping geothermal power is done by harnessing steam which was formed from the water that has been heated up from passing through the hot rocks (magma) in a process known as hydro thermal convection. This heat is then passed through electric generators resulting in electricity.

There are three geothermal designs one can find at a geothermal station: dry steam, flash steam, and binary cycle system.

Geothermal energy is one energy source with the ability to provide power indefinitely. It also has a competitive quality to it, especially when it comes to its costs compared to other sources of power. Geothermal energy is well on its way to becoming the go-to provider of heating for homes and business entities.

For this to happen, the Enhanced Geothermal Systems (EGS), which is a type of technology commonly used in geothermal plants, has to get developed to its full potential. EGS is a technique used to harness dry heat in areas that the steam does not pass through.

The process is not as complicated as it sounds. For one, to break the rocks in the dry, hot bed, high-pressure water is forced through the bedrock. The water is then heated up into steam which gets redirected back to the generators which produce electricity.
