The Role Geothermal Could Play in the World's Energy Mix (Energy Digital)

Sometimes it seems that the more you look for a solution, the more you tend to overlook those right under your nose—or way under your feet.

The problem in this case is the quickening pace of climate change, which threatens to displace millions of human beings in our lifetime, according to an endless number of sources. Some possible solutions have been around for as long as the Earth itself: wind, sun and water.

In the case of geothermal energy, however, the topic is typically relegated to the backburner, which is strange given the impressive implications of the technology. It all starts in the Earth’s crust. The Earth’s crust is made up of hot rock— where temperatures reach upwards of 350 degrees Fahrenheit— that can be harnessed to generate electricity. By utilizing water heated in the crust, geothermal power facilities can generate electricity with steam.
