China Boosts Wind Power

The Chinese are to get more of their energy from wind power, reports the Chinese Information Centre..
The Chinese government hopes that new wind power plants will help solve the problem of energy shortages and cut down on air pollution. The world's largest wind power project, the Guangting plant, is being built near Beijing and city residents may start using wind- generated electricity within two years.
At the moment, 75 percent of the power supply comes from coal, which causes severe air pollution in the country.
"China's wind power resource is abundant - about one billion kilowatts," says Xu Honghua, an expert on generating electricity from wind power. "In addition, its potential is huge. The electricity price of wind power is closest to that of traditional ways of generating electricity".
The new plant will mainly serve the grids in Beijing, Tianjin and Tangshan City of Hebei Province. It will generate 400,000 kilowatt when at full capacity, nearly doubling the electrical energy China currently obtains from wind.
Another large wind power project is being built in the Poyang Lake basin in eastern Jiangsu Province, reports the Xinhua News Agency. The lake is the country's largest freshwater lake.
According to a recent survey, wind energy in the lake basin could generate 1.25 million kilowatts even by the most conservative estimation. Annual wind speed averages five to seven meters per second and up to 5,000 to 7,000 hours of effective wind force each year.
Seven generators have been planned in the basin, each with minimum annual production of 60 million kilowatthours. In thermo- power generation, such production would require more than 25,000 tons of coal and 12 million cubic meters of water, discharging 7.2 million tons of sulfur-dioxide, said Liu Xiaoyan, a senior researcher with the provincial meteorological bureau.
