Thrust doesn't require any energy. You could hang a 747 of the end of a suitable metal bar. That bar would be providing thrust equivalent to the weight of the 747. What's more impressive is it can do it all day without overheating.

When that thrust starts to move the aircraft then everything changes. The metal bar can't do this apart from a tiny movement caused by the shrinkage as heat moves out of the bar.

You can begin to see that the thrust of an engine is only loosely related to its power.
