#Renewableenergy is approaching an important possible inflection point... what happens when #windfarms reach the end of their (expected) technical lifespan?
Do owners of early windframs (often in prime wind locations) invest in upgraded & now much more efficient (if expensive) new installations, or will they walk away having already earned a return... & if the latter, what happens with those sites; will they remain wind farms ?
This may become the key Q. for #windpower this decade.
