Stability and Cost
See also: Wind Power variabilityTransmission capacity of the grid hasn't kept up with the growth of China's wind farms. According to 2009 data from the China Power Union, only 72% (8.94 GW) of China’s total wind power capacity was connected to the grid. In addition, increasing China's wind power capacity means increasing coal use as well, to provide power when the wind isn't available. "China will need to add a substantial amount of coal-fired power capacity by 2020 in line with its expanding economy, and the idea is to bring some of the capacity earlier than necessary in order to facilitate the wind-power transmission," according to Shi Pengfei, vice president of the Chinese Wind Power Association. Shi is also concerned about the high cost of wind power, which makes the industry dependent on the government's willingness to subsidize renewable power. "It isn't that wind power is showing signs of over-heating. It has already overheated."

Famous quotes containing the words stability and/or cost:
“No one can doubt, that the convention for the distinction of property, and for the stability of possession, is of all circumstances the most necessary to the establishment of human society, and that after the agreement for the fixing and observing of this rule, there remains little or nothing to be done towards settling a perfect harmony and concord.”
—David Hume (1711–1776)
“To call a posit a posit is not to patronize it. A posit can be unavoidable except at the cost of other no less artificial expedients. Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built.”
—Willard Van Orman Quine (b. 1908)
