Jarðarhiti

Jarðarhiti refers to the thermal energy originating from within the Earth. This heat is a result of radioactive decay of minerals in the Earth's core and mantle, as well as residual heat from the planet's formation. The temperature of the Earth increases with depth, a phenomenon known as the geothermal gradient. In some areas, this internal heat is closer to the surface, creating geothermal reservoirs. These reservoirs can be utilized as a source of renewable energy through geothermal power plants. Geothermal energy can also be used for direct heating and cooling of buildings and for various industrial processes. Iceland is a prominent example of a country that extensively utilizes its abundant geothermal resources. The utilization of jarðarhiti is considered environmentally friendly as it produces significantly lower greenhouse gas emissions compared to fossil fuels. However, geothermal power plants can sometimes release sulfur dioxide and hydrogen sulfide, necessitating appropriate mitigation measures. The development of geothermal technology continues to advance, making jarðarhiti an increasingly viable and sustainable energy option globally.
