Wind may be key to carbon dioxide-free power

Windmills in China(We would like to have put CO2  instead of carbon dioxide in the heading/ The trick for any editor is to get chemical formulae to look right. The standard test is:

Johnny, finding life a bore,,
Drank some H2SO4,
Johnny’s father, an MD,,
Gave him CACO3,
Now he’s neutralized it’s true,,.
But he’s full of CO2

China, gets much of its pollution from burning fossil fuels. Michael McElroy, a researcher at Harvard University, said China has enough wind-energy potential to generate seven times its current power consumption. In a study published in Science, he wrote that to develop that capacity and meet rising demand would cost about $900 billion.
McElroy said in the paper, “The world is struggling with the question of how do you make the switch from carbon-rich fuels to something carbon-free. The real question for the globe is: What alternatives does China have?”
Electricity from the wind currently accounts for about 0.4% of China’s total generation, the study said. The expansion of wind power is already under way in China and the nation will likely usurp the US’s position this year as the largest market for devices that harness the wind.
 
More wind power would lead to cleaner air and lower health-care costs, which already amount to as much as 4.3% of gross domestic product. Whether it would have any effect on the climate is a moot point and there is much disagreement between scientists (as a generalized body) and climatologists (as a specialized body).
 
Bloomberg reports that China is the world’s largest producer of coal, one of the single biggest fossil fuel-based sources of carbon emissions, and has the third-biggest reserves after the US and Russia. The country consumes about 3 billion tons of coal annually.
