The word geothermal is derived by joining two Greek words, “geo” and “therme”. Geo means earth and thermal means heat; thus, the word, geothermal. The heat within the earth is known as Geothermal, and it’s the most natural sustainable renewable energy generated nonstop. Hence, it never gets depleted. The temperature within the earth’s core is about 10,800 degrees Fahrenheit, making it as hot as the sun’s surface.

According to history, about 10,000 years ago, American Paleo-Indian from North America was among the first to use geothermal heat for their regular living purposes like cooking and washing. They used the heated water from the hot springs for this purpose. However, it wasn’t until the 18th Century when this geothermal energy was used industrially in Pisa, Italy to extract boric acid but it was only in 1904 when Piero Ginori Conti, an Italian scientist, first made the revolutionary invention of using the steam to produce electricity through the geothermal power plant.

Geothermal power plant drill’s about 1 to 2 miles deep inside the earth’s core and extracts hot water, which converts into steam due to the drop in the temperature on the surface above. This steam is then used to generate electricity as the steam helps rotate a turbine, connected to a generator.

With the rise in awareness about the harmful effects caused by fossil fuel on the environment, people are transitioning towards the usage of sustainable renewable energy sources, which is creating space for geothermal industrial projects, which again is leading to the rise in business opportunities for building this industry as well as the need to supply the energy source to the end customers. It has caused a ripple effect, and we at Pencil for Change is here to hold your hand and guide you through.
