“Most of these convective cells of hot water underground Are not coming to the surface, and we now know that the majority of them are actually what we call blind. There's no hot spring, no volcano, and you wouldn't have even known they existed had you not, in most cases, drilled into them accidentally.”

Hoyland: Geothermal will add more firm capacity than clean competitors by 2035
“And so in terms of adding low-cost, firm, renewable energy in the next five to 10 years, we really think there's a chance to add more with geothermal than any other competitive form.”

Hoyland: Deploying geothermal in unconventional regions will take decades
“As drilling costs come down, or as demand for clean firm power continues to increase, we see the economic shifting to where you could start to justify new build geothermal using some of these new methods, and even more unconventional locations. We think that t…”

“Most of the United States growth actually happens in those first one to two decades. And for a while, it looks like geothermal is just going to take off. It's scaling faster than any other renewable at the time. And through the 19 eighties, we had gigawatts of…”
