Wind turbine blades weigh between 35 to 65 tons. Weight impacts efficiency, power generation, and transportation. These blades can weigh from 5,000 pounds (2,268 kg) to 30,000 pounds (13,607 kg) or more, depending on the blade length, material, and turbine size. Vertical-Axis Wind Turbine (VAWT) Blades Vertical-axis wind turbines (VAWTs) have blades that rotate around a vertical axis, as opposed to the. Wind turbines have very heavy blades - at least if we are talking about industrial wind turbines. A medium-sized Rampion, and the Bard VM, the world's largest wind turbine (to date). 5 tonnes), have been shipped from the Port of Yantai in China's Shandong province. These massive blades are destined for installation on what is expected to be the world's most powerful. The weight of a wind turbine blade varies considerably with its size, but typically, a single modern onshore wind turbine blade can weigh between 12,000 and 17,000 kilograms (26,455 to 37,479 pounds). 8-megawatt Vestas V90 from Denmark has 148-ft blades (sweeping more than 1.
