Boost source of electric current throttled by Greens misguidedly (8)
I believe the answer is:
energise
'boost source of electric current throttled by greens misguidedly' is the definition.
I can't tell whether this defines the answer.
'electric current throttled by greens misguidedly' is the wordplay.
'electric' becomes 'e' (this could be a standard abbreviation which I don't know about).
'current' becomes 'I' (symbol for electric current).
'throttled by' is an insertion indicator (inserted letters get throttled or smothered).
'misguidedly' indicates anagramming the letters.
'greens' is an anagram of 'nergse'.
'i' going within 'nergse' is 'nergise'.
'e'+'nergise'='ENERGISE'
Can you help me to learn more?
(Other definitions for energise that I've seen before include "Give vitality to" , "Stimulate activity" , "Activate" , "To banish inertia" , "Motivate" .)
