Which of these resources isn't renewable: Sunlight Water Wind Metal

I would say Metal

Explanation:

Technically, all 4 aren't renewable (but sunlight, water, and wind are considered renewable energy sources), but metal is the best choice

Metal ore will run out and cannot be recreated.

Reasons why I think all 4 aren't renewable

Sunlight will die in around 6 billion years

Water will evaporated in 6 billion years when the sun blows (if it even ever survives the global warming we're facing)

Wind will be gone when the earth is swallowed by the sun
