Why? Wind advocates never tell the complete story because it shows wind is a virtually useless power source in the majority of locations (i.e. places where there is no hydropower with excess capacity).Here is a detailed report on why wind makes no economic or environmental sense in most locations:

Here is a detailed report which shows that installing wind actually INCREASES CO2 emissions because the backup generators waste fuel starting/stopping in order to compensate for wind production.

Here is a report on how wind power generators are paided to shutdown because the grid cannot use the power:

For me the question is simple: I will support wind power when private investors are willing to build and run these things without subsidies or rate guarantees from the government. Until then they are waste of money.
