America's Geothermal Breakthrough | Hacker News

A Hacker News discussion argued that geothermal is already useful for building heating and cooling, especially with ground-source heat pumps and district heating.

The bigger challenge is geothermal electricity generation, which still depends on expensive drilling, deep heat access, and major infrastructure.

Commenters said projects like Fervo Energy show promise, but widespread deployment faces permitting delays, transmission needs, and utility coordination.

Induced seismicity and other geological risks also make large-scale geothermal harder to scale economically.
