More precisely, it _has_ energy: it transports energy from one body to
another. The energy of a photon, the quantum of light/EM radiation/the EM
field, is precisely E = ℎ f, with ℎ the Planck constant and f the frequency
of the radiation. This is known since more than a hundred years now
(Planck, 1900; Einstein, 1905).
From where do you get your energy to live?
How can you see (light)?
What is a solar cell?
What is a cathode-ray tube?
What is a laser?
What is a solar sail?
First read, then think, then post.

That much is obvious.
