Man thought that the Earth was an inexhaustible source of resources, and that his actions upon it would have no consequences. But the consequences begin to arrive and very few believed it, at first. Only a few were able to predict what we all now accept as fact and even less did something in order to prevent what was coming. Soliclima was one of the few pioneers.

A wind farm in Texas tests radar to protect birds

In the U.S., wind farms kill around 7000 birds annually, but, a radar system developed by NASA, could avoid the collisions, detecting when birds approach. t could be considered an air traffic control system for birds.

A wind farm in southern Texas, operated by the Spanish company, Iberdrola, is located within the migration route used by millions of birds each fall and spring and uses, for the first time, radar technology, to avoid the birds crashing into the giant rotating blades.

According to a recent study, 7,000 birds die each year in the U.S., colliding with turbine blades.

This fact puts many environmentalists against wind power and, in the United States, they have managed to abort the creation of several wind farms.

But the new technology used at the Peñascal wind farm in Texas, seems to have found a balance between the conservation of wildlife and conservation of nature by the use of renewables.

This facility, which opened recently, uses radar systems that were first developed by NASA and the U.S. Army, that detect the approach of birds at a distance as far as four miles, consider the weather conditions and determine if there is danger of collision.

If the birds are in danger of flying into the rotating blades, the turbines are programmed to stop, automatically restarting, once the birds have flown by, said Gary Andrews, the chairman of DeTect, Inc, the Florida company that developed the technology.
Ornithologists, however, are skeptical about this solution, as it ensured that, despite avoiding the collision, the mere presence of wind farms already is a nuisance to birds.
