the claim

Wind turbines generate more energy over their lifetime than is used to build them.

Recorded sources

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that wind turbines generate more energy over their lifetime than is used to build them?

Yes. A peer-reviewed life-cycle energy analysis reports that over a 20-year life a wind turbine produces many times more energy than is embodied in its production, and a Skeptics.SE answer cites multiple studies finding operational output 20-25 times construction energy with payback in months.
