Washington is shifting its gaze below the surface, examining what could become a substantive piece of its clean-energy future: geothermal power. The Department of Ecology has unveiled a new collaborative initiative designed to evaluate the state’s underground thermal resources, mapping the opportunities — and risks — of tapping heat from the earth for electricity.

The effort centres on three promising locales identified by the Washington Geological Survey: the area beneath Mount Baker in the state’s northwest, the region around Mount St. Helens, and the Wind River Valley south of the volcano.

Notably, this is early-stage: Washington is still in the “what if” phase rather than full-scale project rollout. As the report emphasises, “we are leading a new collaborative process to identify potential risks and opportunities related to developing the state’s geothermal resources.” EIN Presswire Among the items under scrutiny: underground water usage, seismic and fault risk, permitting pathways, and public consent. The state is taking care to engage stakeholders before committing to large-scale drilling.
For the geothermal sector, Washington’s move signals an important shift: the Go-Go-West states have already advanced geothermal electricity in a number of baseload applications, but Washington until now has largely focused on ground-source heating and low-temperature uses. This process suggests the state believes it has enough geological potential to consider elevation to true power-generation scale.
If successfully aligned with permitting, tribal engagement, utility demand and investment, geothermal could emerge as a long-duration, firm-clean-energy contributor in Washington’s portfolio — just as wind and solar are increasingly saturated. The earth beneath could offer the next frontier.
