to reduce seismic hazards after several geothermal projects there have produced small earthquakes. In the United States, scientists have correlated earthquake activity with geothermal development in several locations. research is ongoing to address and mitigate the seismicity issues. Despite these problems, geothermal remains a promising source of clean energy for the future.

Greater potential for geothermal energy developments lies in sedimentary basins than in the rocks of the Canadian Shield.
