Unlike solar, wind energy does not scale linearly but instead exponentially. That's why people who build wind turbines to sell the power construct huge ones in very windy places.
When electricity prices are at $0.10-$0.20/kwh, this $15000 "investment" will pay for itself in 50-100 years. Unless these turbines cost $100 each, they will only make sense where electricity is unavailable.
