Want networked geothermal on your street? Add yourself to our map!
We’re collecting data to create a visual database of public interest in geothermal networks. We’ll share this map with gas utilities, legislators, and regulators. The more of us showing that we want this low-cost, safe, and healthy clean energy for our futures, the greater the impact.
