Surprising find in approachable energy supplier (4,4)
I believe the answer is:
wind farm
'energy supplier' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'surprising find in approachable' is the wordplay.
'surprising' is an anagram indicator.
'in' means one lot of letters goes inside another.
'approachable' becomes 'warm' (I can't justify this - if you can you should give a lot more credence to this answer).
'find' is an anagram of 'indf'.
'indf' inserted into 'warm' is 'WIND FARM'.
Can you help me to learn more?
(Other definitions for wind farm that I've seen before include "Group of aerial rotors generating electricity" , "this should give you plenty of energy" , "generator" , "Power plant that uses moving air to generate electricity" , "Area of power turbines" .)
