Speculation: China's power needs are growing more rapidly, so there's more additional power coming online in China. While, in the US, power consumption growth is slower. A larger percentage of overall power sources need to be replaced, where there's less pressure to do so.
China's power consumption has plateaued and it currently has massive over-capacity - so much so that it's halted the construction of some new coal plants.
Thanks for the link. Puts the lie to my speculation :) Do you have a link for China's wind-powered generation capacity?
They aren't doing that to stop 'climate change'; the are doing it to stop actual pollution -- as in particulate pollution that has made places like Beijing uninhabitable. The Chinese would gladly let the Earth get a half degree warmer because that would mean less need for coal for heating, thus reducing their particulate pollution even more. They aren't scared of the CO2 boogeyman, but of actual, cancer causing particulate pollution. They aren't in to the "global warming" thing because they aren't looking for a means to control the means of production or income distribution -- they already do. They have a desire for reducing pollution and achieving energy independence -- they don't buy into to the sky-is-falling hysteria promoted by Western anti-capitalists. Rather ironic one might think.
