Is changing down through the gears a bad habit

I always use gears to slow down than brakes. Engine braking is far more efficient than using brakes which is wasted energy unless you have kers. It is all about judging what is in front of you.

So if you change to a lower gear for increased engine braking, where does the energy go?

Basic law of thermodynamics, heat is work and work is heat. All braking generates heat.

It was a rhetorical question in the first place.
