Geothermal Energy Applications and Challenges

Geothermal energy, derived from the Earth's heat, is abundant but challenging to extract affordably. It is easily accessible in regions with high surface temperatures, like Iceland, and is used for heating and electricity. Geothermal energy is flexible, providing base load power or adjusting to demand. However, high-temperature areas are rare, and new extraction methods are costly. Low-temperature geothermal is also expensive. Iceland exemplifies successful geothermal electricity use.
