Subject: BRK's NV Energy has geothermal
"Last year, Houston-based Fervo began operating a first-of-a-kind plant in Nevada. The 3.5 MW project is now supplying electricity directly to the Las Vegas–based utility NV Energy. The enhanced geothermal system uses horizontal drilling techniques and fiber-optic sensing tools to create fractures in hard, impermeable rocks found beneath the surface. Technicians then pump the fractures full of water and working fluids. The hot rocks heat those liquids, eventually producing steam that drives electric turbines."

"In recent years, both the U.S. government and private investors have started spending hundreds of millions of dollars to develop ​'next-generation' technologies that make it easier and cheaper to access the earth’s heat nationwide. If these systems reach commercial scale, they could expand the nation’s geothermal capacity by more than twentyfold, adding at least 90 GW of firm and flexible power to America’s grid by 2050, the U.S. Department of Energy said in a report released on March 18. That’s equal to nearly 10 percent of current U.S. electricity capacity."

p.s. Only writing this because of the BRK connection. I'm not going to go OT on the climate disaster. However, as BRK is strongly connected to energy, these connections in the transformation of energy will be frequent and continuing. There are insurance connections as well. The climate disaster is going to be an increasing factor in everything. Greenhouse gas emissions are higher than ever. The average global temperature for 2023 topped the pre-industrial average by 1.3C close to the 1.5C "limit" in the Paris Agreement. There were 28 weather events in the US last year totaling over $90B in damages. 5% of Canadian forest area burned in 2023. Scientists say we are close to five tipping points where consequences are serious, such as global-scale loss of capacity to grow major staple crops.
