Global Geothermal Power: Policies, Funding, Wells, Strengths, Opportunities and Barriers Geothermal is moving into a broader investment cycle. In 2026, the story is no longer limited to volcanic power plants in a few classic markets; it now includes enhanced geothermal systems, closed-loop designs, district heating, superhot rock, lithium from brines and industrial heat. Across the United States, Canada, Germany, the United Kingdom, Australia, New Zealand, Japan, Iceland, France and Italy, the sector is being shaped by a simple question: who is de-risking the first wells, and who is ready to finance the next ones? United States: the next-generation testbed The United States has the broadest geothermal innovation ecosystem in this group, with a mature conventional base in the West and a fast-growing next-generation pipeline. The main policy signal in 2026 is the Department of Energy’s US$171.5 million funding opportunity for next-generation geothermal field-scale tests, exploration...
Boise’s $1 Million Geothermal Breakthrough: A Bold Step Toward Affordable Clean Heating By: Robert Buluma A City Turning Underground Heat Into Housing Solutions In the global race to build cleaner, more affordable cities, innovation often emerges from unexpected places. One such place is Boise, Idaho, a community already known for its pioneering use of geothermal heating. In early 2026, Boise captured international attention after winning a $1 million grant through the Bloomberg Philanthropies Mayors Challenge, a global competition that rewards cities developing groundbreaking solutions to pressing urban problems. The recognition was not simply about technological innovation. Boise’s winning proposal demonstrated how geothermal energy can be used to reduce the cost of living , specifically by lowering utility bills for residents in affordable housing developments. With the award, Boise now plans to build a new apartment complex powered by geothermal heating—potentially ...
