What happened

Thanks to a relatively easy and extremely rare drill test down to 1,000 feet under the high school football field, Aspen School District will be a key proof-of-concept project for a state-backed push into Colorado’s rich geothermal energy sources.

Why it matters

Ground-source geothermal heat pumps circulate water deep underground to gain energy from stable temperatures.

Common ground

In zero-degree surface temperatures in winter, the circulating lines bring up 55-degree water as the starting point for heating.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
