What would happen to the world if it didn't have energy?

What happens if you don’t have energy?

When you say ‘you’ do you mean me, or you, as in our bodies, or if energy didn’t exist in general? Either way, without energy, no metabolic processes could occur, no continuation of the cycle of energy transference, no ‘work’ could be done. Energy is required for anything to occur, without it there would be no ‘causality’ for things to change from one moment to the next, entropy would be king, light would no longer ‘be’, the universe would go dark, and existence itself would simply grind to a halt, everything down to muons and quarks simply fading into non-existence.

The answer is reflection.
