Wind power will make sense when it can be 100% privately funded and run as a profit-making business.

That means someone can look at their piece of windy ground and go to the bank and say: "Here is the wind chart (and a bunch of other expensive studies and environmental reports), here is the cost of the gear, transmission equipment and maintenance, and here is when you get paid back." Just like any real business.

The government should continue to subsidize the R & D.
