The Front CoverFor wind turbine blades, generally two main root connection types exist to connect the rotor blade to the hub of the turbine: the T-bolt connection or bushing technology.

In the article on page 7 the bushing connection is discussed. Publisher's NoteEuropean Commission makes fighting climate change central to Europe’s economic recovery Features
