Source of green energy wired in but not initially working (4,7)

I believe the answer is:

wind turbine

I'm a little stuck... Click here to teach me more about this clue!

'source of green energy' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'wired in but not initially working' is the wordplay.
'initially' suggests taking the first letters.
'working' indicates anagramming the letters.
The initial letter of 'not' is 'n'.
'wired'+'in'+'but'+'n'='wiredinbutn'
'wiredinbutn' with letters rearranged gives 'WIND TURBINE'.

Can you help me to learn more?

(Another definition for wind turbine that I've seen is " Power generator".)

I've seen this clue in The Independent.
