Bedrock Energy wants geothermal to make data centers cooler and offices more comfortable

Climate /

Oil and gas isn’t the only source of energy lurking under our feet. Drill deep enough and the Earth’s temperature stays consistent enough that it can be a source of heating and cooling for homes, offices, and data centers. But in many regions, geothermal wells today bottom out at around 500 feet, a limitation that
