Wow this has a lot of replies!

Yes, you get a lot of the energy back, BUT there is a huge problem!

Large airliners incur a LOT of additional drag to slow down while landing. Some of that is entirely intentional, some is less intentional.

It is highly preferred to deploy the landing gear before touching down. Failure to do so may lead to a hard landing and additional paperwork, so airlines do not allow the captain to exercise their own discretion.

Extending the flaps maintains lift at lower speed, and higher flap settings allow even lower speed. The highest flap setting generally also deploys leading edge slats.

If the wheels of the airliner touch down and detect the weight of the plane then spoilers kill the lift of the wings, air brakes fully deploy, as well as thrust reversers.

All of these things add drag, which uses up all that energy you've been converting.

The upshot is that each landing attempt uses a LOT of energy, and you have to use fuel to replenish that energy after every attempt.

In other words, yes you get it back, but only for one landing attempt.
