As the number of wind farms increases in the United States the number of bird deaths will likely go up. Designers are looking to a variety of ways to avoid wildlfie harm. One involves radar.Alternative-energy-news.info reports:
The new Peñascal wind farm in Texas hopes to become a model for responsible development by installing new radar technology to protect migratory birds and wildlife.
The same technology was originally developed for NASA and the US Air Force. It can detect approaching birds up to four miles away and assess their altitude, numbers and visibility. It then analyzes weather conditions to determine if they are in danger of flying into wind turbine blades. If so, the turbines are programmed to automatically shut down and restart once the birds are a safe distance away. See full article:
