Renewed energy around the garden (4)
I believe the answer is:
eden
'garden' is the definition.
(Garden of Eden in the Bible)
'renewed energy around' is the wordplay.
'around' indicates a hidden word.
'EDEN' is hidden in the letters of 'renewed energy'.
'the' acts as a link.
(Other definitions for eden that I've seen before include "The original garden?" , "project in the south west" , "5,27 [PRIME MINISTER]" , "Genesis location" , "Paradise - ex-PM" .)
