The first wind farm in Dallas County spins atop a historic building at El Centro College in downtown Dallas.
The community college fired up the farm last month to mark Earth Day, and now 80 turbines are generating enough electricity to power 2,000 computers.
The wind farm was proposed by David Browning, the school’s vice president for business affairs. He said that when he began working there in 2008, he was struck by how windy it was around campus.
“Every time I walked outside, I would get hit by wind,” Browning said. “We actually got statistics showing how much our average speed is, which comes to 20 to 25 mph.”
In the next six years, El Centro tested many prototypes before settling on turbines and a supporting metal grid from Hydro-Star Energy. The total cost was $240,000.
