Wind always costs the same and will always be here!
And with all the R&D that's being done...the costs of these systems and their energy/power efficency constantly rising, WE ARE A LOT CLOSER to becoming one of the cheaper energy supply industries out there.
According to a 2011 report by BloomBerg New Energy Finance, in Parts of Brazil, Mexico, Sweden and the United States, Onshore wind power is down to $68 per Megawatt (MW), while COAL in those SAME REGIONS is about $67 per MW. DEMAND IS GROWING too. Between 2009 and 2010, Vestas, one of the world's larget wind energy firms, reported orders rising 182%. In 2011, Worldwide turbine installations climbed 20% and are projected to DOUBLE by 2015
