Using Nevada as an example, the 200 megawatts of electricity produced by geothermal energy plants spares the air 1.7 million tons of carbon dioxide, 315 tons of nitrogen oxides, and 11,000 tons of sulfur oxides that would be produced by a coal-burning power plant of the same capacity each year.
Sulfur oxide increases the sulfur content of the soil and causes human health problems, crop damage and acid rain.
Researchers from the Department of Energy's Pacific Northwest National Laboratory (PNNL) revealed earlier this month during the 230th national meeting of the American Chemical Society in Washington, DC, that the mineral cryptomelane "holds promise to absorb the toxic sulfur oxides that can degrade the emission control systems on diesel vehicles."

The Korea Times recently reported that new vehicle emissions regulations in Seoul and Kyonggi Province that went into effect late last week, which are expected to reduce dust and sulfur oxide emissions by 20 percent from July, require public organizations with more than 10 vehicles to purchase low-emissions automobiles comprising 20 percent of their total fleet and establish annual emissions testing requirements.
Marubeni will be responsible for running the stations, while Toho will build the facilities and supply natural gas, demand for which is expected to rise mainly as a fuel for trucks because of its low pollutant content such as sulfur oxide and nitrogen oxide.
The programs urge vessel operators to slow down to 12 knots or less within a certain range of the ports to reduce emissions of carbon dioxide (CO2), nitrogen oxide (NOx), and sulfur oxide (SOx) in coastal areas to conserve coastal environment, and offer annual rewards to vessel operators that achieve extraordinary compliance percentages.
In addition to reducing PM emissions, AP said the new fuel standards are expected to reduce sulfur oxide emissions by 78 percent and nitrogen oxide emissions by approximately three percent.
A team led by George Thurston published research in the 6 March 2002 issue of the Journal of the American Medical Association presenting what he calls the strongest evidence to date that long-term exposure to airborne P[M.sub.2.5] and related products of sulfur oxide air pollution is an important environmental risk factor for cardiopulmonary and lung cancer mortality.
The sulfur emissions control areas place restrictions on nitrogen and sulfur oxide emissions from ships within the Baltic Sea, English Channel, the North Sea and both US coasts.
