Obsolescence of wind turbines worries Springview

This pair of pioneer turbines put Springview on the map just nine years ago, as a U.S. Department of Energy demonstration site to test the feasibility of small wind farms. They were Nebraska's first commercial wind turbines. With a capacity of 750 kilowatts each, the duo generates enough electricity to power about 350 homes - less than half of what today's turbines can do. The turbines have been plagued with repair and maintenance issues, causing extensive downtime and expense.

Ropin' the wind

Greenblatt noted that while wind power could produce impressive amounts of peak energy during strong gusts, the biggest problem was wind power’s intermittency. The problem could be addressed by a process called compressed air energy storage, where excess energy could be used to pump compressed air into underground storage facilities that could include abandoned mines. When the wind was not blowing, he said, the compressed air could be tapped and combined with the burning of natural gas to create high-efficiency electrical generators approximating the efficiency levels of coal-fueled power plants.
