In biofuel it is this snobby (7)
I believe the answer is:
elitist
'snobby' is the definition.
(I've seen this in another clue)
'in biofuel it is this' is the wordplay.
'in' says the answer is hidden in the clue.
'ELITIST' is hidden in the letters of 'biofuel it is this'.
(Other definitions for elitist that I've seen before include "arrogant" , "Favouring a chosen few" , "Narrowly superior" , "One without the common touch" , "No egalitarian" .)
