Starting in the 1960s, the United States became a world leader in building large-scale geothermal power plants.That changed in the mid-2000s with the fracking boom. Drillers turned their attention to oil and gas. And as wind, solar and batteries got cheaper, bankers and developers put their money into those resources.Today, geothermal development around the world has flatlined.But a small legion of clean energy entrepreneurs is working quietly in the background on innovations that could catalyze the geothermal industry once again.One of those entrepreneurs is Tim Latimer, Co-Founder and CEO of Fervo Energy.Fervo Energy is a geothermal developer using advanced drilling techniques from fracking in the oil and gas industry to make it easier to find and harness heat underground. Tim calls the 2020s "the geothermal decade." We can't transition to a zero-carbon grid without round-the-clock clean energy resources to supplement wind and solar - and geothermal offers that always-on feature.Tim believes a combination of technology innovation and public attention are setting up a new phase of growth.Emily spoke with Tim about how he's combining his expertise in oil & gas drilling with a dedication to solving the climate crisis -- and using his experience to break open an overlooked renewable resource.Watt It Takes is brought to you by Google.
