Although stopping climate change is challenging, it is imperative to slow it down as soon as possible by reducing greenhouse gas emissions. But how can we meet the growing energy demand while reducing our use of polluting fossil fuels? Geothermal energy is an efficient, non-polluting solution but in certain cases geothermal operations must be handled with care. Reaching the most powerful sources of available energy means drilling deep into the layers of the earth’s crust to find geothermal fluids with high energy content (hot water and gas released by magma). Yet, the deeper we drill, the greater are the subsurface unknowns controlling the stability of the Earth’s crust.
