April 30, 2004 [SolarAccess.com] The American Lung Associations of the Bay Area have selected Calpine Corporation and its Geysers geothermal operation for the 2004 Clean Air Award for Technology Development. This award recognizes Calpine’s commitment to clean renewable energy, which improves air quality. The Geysers makes up a 30 square mile area along the Sonoma and Lake County border and is the world’s single largest source of renewable geothermal power, according to the comapany. Comprised of 21 plants, The Geysers accounts for almost 70 percent of the average North Coast power needs from the Golden Gate Bridge to the Oregon border. The Geysers avoids the pollution that would result from burning nearly nine million barrels of oil per year to produce an equivalent amount of electrical power. Lake County, downwind of The Geysers, is the only air district in California to have met all federal and state ambient air quality standards for the past 16 years.
