Wind energy costs have dropped over 60% since 2010, making turbines competitive with fossil fuels. Leading manufacturers Vestas, Siemens Gamesa, and GE Renewable Energy invest heavily in research and development for larger, more efficient designs. Major developers Iberdrola and NextEra Energy drive global deployment across Asia, Europe, and North America. Intermittency and wildlife concerns continue challenging the industry but remain manageable through technology and careful planning.
