Where do you get the idea that wind electricity is incredibly more expensive than coal electricity?
Modern windpower can be cost competitive per megawatt-hour.
From table 2 here http://en.wikipedia....icity_by_source
Levelized average cost in 2016 for new construction onshore wind is $97 per megawatt-hour, conventional coal is $94.80, advanced coal with CCS $136.20 and advanced natural gas combined cycle (without CCS) $63.10.
Wind electricity does have the intermittency problem though, need other sources of electricity too.
It is cheaper to build a megawatt of "nameplate" capacity of coal generation than wind generation. Then somebody has to buy the coal to produce megawatt-hours of electricity. "Levelized cost" is supposed to take into account construction costs and fuel costs and operation/maintenance costs too.
