Solar panels are highly recyclable after their extremely long life. Certainly no worse than oil, even if left alone (which won't happen, sincethey contain valuable materials).

Turbine blades are mostly fiberglass, which is about as neutral of a material as you can get. They are buried in a landfill (worstcase) after producing tremendous amounts of energy. New designs are lasting longer and being made recyclable, since so many people have this sticking point (even though no fuel oil is recyclable)
