Rooftop wind turbines?
parapet wall-based turbines has become the rage in green architecture. At the Arizona State University's Global Institute of Sustainability, Lord, Aeck & Sargent and Gould Evans Associates installed six wind turbines as part of a redesign. The AVX 1000 turbines were supplied by Monrovia, CA-based AeroVironment; the units weigh 130 pounds, and capture wind between 4 and 120 mph with an average wind speed of 30 mph, to produce up to 1,000 watts of energy. - Read More

Cost of wind turbines per unit - MW, KW etc
The cost of commercial wind turbines varies from $1 to $2 million per MW of nameplate capacity. Turbines 2 MW in size cost roughly $2.8 million installed capacity. Significant economies scale. Smaller farm or residential scale turbines cost less but they are more expensive per KW of energy. This would indicate a 10 kilowatt machine might cost roughly around $48,000. 100 kilowatts wind turbines would cost roughly $2,800 to $4,800 per kilowatt of capacity.

Small scale wind turbines don't perform well enough
Though the turbines surveyed by Encraft did generate enough electricity to light an energy efficient home, on average ?this still only represented 5-10% of the manufacturer?s claims? regarding output. The best performing turbines surveyed could generate enough electricity to offset the amount of electricity needed to manufacture them in two years, while the worst ones could take up to 40 years to do so. - Read More
