'using turbine in riot' is the definition.
I know nothing about this answer so I can't tell whether this works.

'as a penalty' is the wordplay.
I cannot quite understand how this works, but
'as' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
'penalty' could be 'retribution' (retribution is a kind of penalty) and 'retribution' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
