Bird deaths at some early wind farms were alarmingly high.

Challenges remain, but the technology has come a long way in recent years, and wind farm operators have learned plenty of tricks, too, like the importance of shutting down the machines in high winds and the best places to put them to begin with.

The turbines have grown larger, and more effective. One model made today by Vestas, a Danish turbine manufacturer, can produce 300 times as much power as a turbine sold 15 years ago, according to Finn Strom Madsen, the president of technology research and development for Vestas.
