Road Tripping through the Geothermal Frontier

And they’re off! After more than a year since the announcement of available funding, the project teams selected for our Frontier Observatory for Research in Geothermal Energy (FORGE) each hosted our geothermal experts at their candidate sites this fall. We’re calling it our road trip through the geothermal frontier.

Pilgrim's Progress: An Update on Geothermal Potential in Alaska

A resource in central Alaska is showing promise for geothermal development—the renewable energy that draws on Earth’s natural heat for electricity and other uses. The myriad benefits of this clean, domestic power source make geothermal exploration an attractive proposition for this state, where off-grid demand means that Alaskans often use expensive, polluting diesel power.
