If you can convert energy that easily you could convert light into gravity. With a large enough source of power one could presumably build a practical faster than light drive since all you need to do is keep converting incoming energies into outgoing energies. Its like a ramscoop that isn't limited to what it can convert info fuel.

If all energy is basically the same subatomic particles in the setting than even biology could be reshaped. I don't think we'd be dealing with a fantasy or steampunk setting. You be looking at super advanced sci-fi stuff here. If you can convert one type of energy into another then really the skies the limit as far as what you can achieve.
