Electromagnetic energy.
Photosynthesis is powered by light energy from the sun; and sunlight is a type of energy called electromagnetic energy or radiation. Electromagnetic energy travels in space as rhythmic waves.
That could be electromagnetic waves, or gravitational waves.
Electromagnetic waves, which includes light. Also, gravitational waves.
Electromagnetic energy travels by waves. These waves can travel through space and through many types of matter. Electrical energy of sufficient voltage can arc through space and some matter (lightening for example). More commonly, electrical energy travels through conducting media such as wires of copper. AC electricity could be considered a wave, but not in the same sense as electromagnetic energy.

Through Radiation
Sound is a form energy that travels to us through compressional (or longitudinal) waves.
