1️⃣Geothermal heat‑pump systems can deliver heating & cooling for whole neighborhoods
“I always thought this method could be used to provide a/c for neighborhoods, operated as a neighborhood utility.” – WarOnPrivacy
“In the nordics it is common to have ground source heat pumps … that are run backwards in summer to cool the house …” – wood_spirit
“It seems so smart.” – jjtheblunt
2️⃣ High upfront costs & regional economics make adoption spotty
“It's expensive. A relative has one in the northern Great Lakes, they wouldn't have installed it if their house had access to natural gas.” – maxerickson
“There's a pretty significant upfront cost in getting them drilled … the cost difference is pretty massive—3‑10× for a vertical system.” – zrail
3️⃣ Scaling geothermal depends on new drilling & EGS innovations
“Several companies are now building upon existing techniques for accessing geothermal resources by integrating enhanced geothermal systems (EGS) into operations.” – hunterpayne
“It does work technically … but scaling takes a lot of time and money.” – mgfist
“The core breakthroughs were … developing PDC bits … high rates of penetration in drilling out these horizontal wells.” – micro2588
