The worldwide cost would be very roughly $20 billion per year, or 4 months of the War in Iraq -- to put things in perspective.
Oops. I must have dropped a factor of 4 or 5 somewhere. The actual "Wind Force 12 Plan" says the cost would come to 80 billion Euros per annum. The cost of generation in 2020 would be 2.45 Euro-cents/kWh, which would be cheaper than any alternative today, including coal or fission. But not unrealistically cheaper.
This plan is an impressive 52-page document. See: http://www.ewea.org/documents/wf12-2005.pdf - Jed
