Why is the jet stream powerful?

In any weather situation, the clash between cold and warm airmasses causes a release of energy.

Erica's Answer:

In the very upper levels of our atmosphere, this energy release takes the form of kinetic energy, which is the energy of motion. The air starts to move really fast! That is the jet stream- simple as that!
