Wind turbines are ageing – what happens next?

After this, the turbine must be removed from its site. "Once the turbine is decommissioned, cranes and other equipment are used for the removal of the systems," says Singh. "Some project infrastructure, like overhead lines, underground lines and substations, may be reused. Turbines are dismantled and the parts are removed.

Wind Turbine Blade Aerodynamics

The wind turbine blade on a wind generator is an airfoil, as is the wing on an airplane. By orienting an airplane wing so that it deflects air downward, a pressure difference is created that causes lift. On an airplane wing, the top surface is

Wind turbine blades pose a challenge to many landfills as their size and composition require specific equipment for processing and disposal.4 Counties may choose to limit the number of blades a local landfill may accept, or ban turbine blades from local landfills

Turbine Blade Maintenance: More than a Safety Issue

Wind turbine blade damage can occur in several ways, and almost all of those ways have to do with three things: dirt, cracks, and moisture. Any of the three main culprits decreases the blades'' aerodynamics and disrupt air flow, forcing the turbine to work harder to produce power. The dirt comes first, which is why cleaning your blades

6 FAQs about [How to remove wind turbine blades]

Should wind turbine blades be buried?

Now, just 2 years later, Veolia runs a program that has already turned about 2,000 of the giant blades into a valuable commodity—cement. When wind turbine blades reach the end of their 20-to-25-year service lives, they usually end up in landfills. But in the past several years, energy companies have sought ways to avoid burying retired blades.

How are wind turbine blades recycled?
