A vertical-axis wind power machine has adaptive airfoils to extract energy at low to moderate wind speeds, and also at higher speeds. The systems and methods described herein employ control system techniques to manage large, variable-area sails, which can be made of durable flexible fabric, such as that used in modern sailboats. To match wind conditions, sail area can be adjusted through furling and unfurling techniques. For low wind speeds, the sails can be mostly or fully unfurled. At higher wind conditions, the sails can be partially furled. For extreme weather conditions, furling is complete. Sail pairs rotate around a central axis to generate electricity.
