once U figure out where I am coming from , one might be able to see where I am going………the world is coming to WIND POWER for China and the play in China to invest in for the next 10 years is APWR , which GE and the communist China government has also invested into for the long run and the health of China.
APWR is profitable, builds green power plants, and is a coming wind turbine maker monster in China being helped by GE and the Chinese government! We must go GREEN in CHINA or we all are going to die eventually quicker than later!
Even so, today 80 percent of China’s energy comes from burning coal, and only 0.4 percent from wind.
“China’s fossil energy consumption is so large that a large-scale conversion to renewable energy there is critical for addressing climate and air pollution problems,” said Mark Jacobson of Stanford University, who was not a part of the study.
The details of this study provides practical information that policymakers and developers can use, he added
Michael McElroy and colleagues at Harvard University in Cambridge, Mass., and Tsinghua University in Beijing estimated the potential for wind energy across China. They excluded unfavorable areas, such as those with high populations, dense forests or steep slopes.
They combined the resulting map of China’s wind energy potential with estimates of how expensive wind energy would be in different locations throughout the country.
There is well more than enough wind to provide all of China’s electricity needs, the researchers found. Earlier this year, they reported that wind could provide 18 times more energy than the 2005 demand.
By incorporating economic information in the new study, the group found that the 2030 electricity demand could be provided at a price of 0.516 yuan (7.6 U.S. cents) per kilowatt-hour of electricity.
“The price of 0.516 RMB per kilowatt-hour falls into the range of prices in existing wind projects in China,” study co-author Xi Lu of Harvard told Discovery News.
Developers of Chinese wind projects are guaranteed a price for power for an initial period — typically about 10 years — by the provincial governments as part of an up-front bidding process.
The team also calculated how much wind could be supplied at a price comparable to the price of coal-generated power, 0.4 RMB per kilowatt-hour. Even at this price, China could supply 23 percent of its 2030 electricity needs with wind, reducing its CO2 emissions by nearly 10 percent, about 2 percent of today’s global total.
Meeting the 2030 demand with wind power would not blanket the whole nation with windmills, Lu added. “It is estimated that wind farms only take up land areas of 0.5 million square kilometers (193,000 square miles), which is only three quarters the area of the state of Texas.”
What’s more, the turbines themselves only occupy about 2 percent of the land they stand on. “The lands do not necessarily lose their original functions, such as agricultural fields or pastures,” he said.
