Geothermal Energy

Geothermal energy is another type of renewable energy that engineers take into account. Geothermal energy is special in the sense that the energy is obtained from the heat from the earth's core. Many big named companies are using geothermal energy as a way of producing renewable energy for our planet. A new thing that I learned about geothermal energy is over the years water seaps into the earths crust. The water under the crust will later be heated from the core and then changed into use as energy. Below is a attacthed video describing how exactly geothermal energy is created. Is it possible to only rely on geothermal energy for the future or do we need to find other ways to use renewable energy?
