Thanks Clive.

So, "on his own power" is not standard English?

"The submarines operates on/under nuclear power."
"The car operates on/under nuclear power."

So, is it "on" or "under"?

Hi,

'Under his own power' is a fixed expression meaning 'he did it by himself, unassisted".

This is not the intended meaning in your following examples.
"The submarines operates on/under nuclear power."
"The car operates on/under nuclear power."

Hi,

No, it's fine.

I meant that 'on' is a more natural choice with the verb 'operate', in the context of your previous examples.

Really, the choice preposition is very dependent on the verb and on the context.
