Geothermal: The Promise and the Pitfalls: RENO, Nevada --- Reno just might be the greenest little city in the

RENO, Nevada --- Reno just might be the greenest little city in the world. Ormat’s Galena Power Plant at the edge of town provides the city with 100 megawatts of carbon-free electricity, or enough for 20 percent of Reno’s daytime electricity and 50 percent of its nighttime power. Put another way, you could power every home in town with the electricity from the plant. Pumps pull 6,000 gallons of water a minute out of reservoirs 3,000 feet below the surface. The water, naturally heated by geologic forces to approximately 300 degrees Fahrenheit (150 C), boils a chemical refrigerant contained in sealed loops. The refrigerant, now a gas, cranks a turbine. But just as important is the quality of power. Unlike solar or wind farms, Galena churns predictable, baseload power 24 hours a day that is relatively easy for the grid to accommodate. It doesn’t even cover much land: it looks...
