Mr Schwartz forgot about the huge difference in capacity factor between coal and wind. You need 3 times the wind to equal coal and 4 or 5 times versus nuclear, plus all the gas plants to back up the wind farms. Let China go bankrupt building wind farms.

A sublime article about windpower in china and the mammoth technical issues they are facing. CHINA: Not everyone is upbeat about the future of Chinese wind. Miao Wei, vice-minister of the Ministry of Industry and Information Technology (MIIT), recently astonished listeners at the annual meeting of the National People's Congress by declaring most of the country's wind power plants "image projects" built by local authorities more for show than to meet energy demand. Miao was particularly irked by the huge wind base in Jiuquan City, in China's north-western Gansu province. It is the country's first 10GW-level wind project.

Among the many issues not discussed re wind power is the "footprint" of an equivalent generation station compared to a typical fossil or nuclear fuel based generation station. A small fossil utility unit is 500 MW; some (nuclear) are as big as 1200 MW. The largest land based wind towers (to date) are 2.5 MW. To generate 500 MW, 200 wind towers are required. If we factor in the 30% availability factor, three times that number are required, or 600 towers. That equates to a 25 x 25 layout. Given the 400 foot height of the towers (nominal), the spacing between towers is 800 feet. This equates to a land area in excess of 13 square miles, not counting power distribution yards, interconnecting cable (towers and/or trenches), emergency back up power, maintnenance garages, operations offices, etc. Also, never discussed is the noise, rotor shadow, impact on wild life, impact on adjacent property values, or maintenance requirements. While I do not oppose wind power development and deployment, it is necessary that ALL issues be discussed, something the environmentalists and media tend to avoid.

still wind power is so much cleaner on the long run

What a lot of people also forget is that the Chinese government IS Chinese business. Nothing happens without direct government involvement there - no oversight committees, no environmental impact studies, no health and safety procedures to follow. That is why, and how, the Chinese government runs roughshod over its people and its territories.
And also why so many American businesses love working with the Chinese government. Nothing quite props up the bottom line like slave labor and no pollution/health/safety/quality controls...

The Apples with apples thing bears closer scrutiny, Wind farms are constrained by the local wind, - 30 to 40% of their rated output, (unless better storage is developed) but a coal fired network is limited to the usage requirements, - it has to meet the peak power requirement, but can not afford to generate that in non peak parts of the day, so a 300 mW coal fired power station is probably lucky to average 40%, more like 20%.
Nuclear, on the other hand, is difficult to ramp up and down (and more likely to go bang when you do that) and is also extremely expensive, so has to be running fall bore 24/7, with Coal and Gas stations the flexible ones at a price, Hydro the most flexible, and Nuclear the spoilt child.
That is why people who understand this whole scenario are talking smart Grids, - to work out ways to balance these loads to get the greatest penetration of renewables and at the lowest cost, - however Hot Rock Geothermal is an element that when many more are developed has that huge flexibility so that will set the cat amongst the pigeons. - Bye bye Nuclear.

Couple this with their growing solar and other renewables capability... The devices and machines (cars, industrial equipment -including robotics) that will have the ability to be charged up (lithium batteries), using these energy sources and the effect is multiplied.
