How Much Energy Is Required to Build a Wind Turbine?
Wind energy has a high Energy Return on Investment (EROI), generally ranging from 15:1 to over 50:1 for modern turbines, meaning they return 15 to 50 times more energy than is used to manufacture, install, and operate them. Onshore wind typically provides higher returns (17–40+) compared to offshore (12–20), with energy payback times often under one year.
