It does, but that consumable releases no CO2 or other greenhouse gas into the atmosphere. That seems to be the clear and present danger that "renewables" are trying to limit. Nuclear accomplishes this, and has the possibility that we could use it to sequester carbon if enough capacity was built.
Would one call geothermal power non-renewable because the radioactive decay in the earth that heats the interior isn't replaceable by a human?
How about all of the hydrogen atoms that irreversibly fuse into helium in the sun, not to mention the materials to make the solar panels and wind turbines to harness that power?
Green/renewable/sustainable aren't complete synonyms. As a shorthand people consider huge natural sources like the Sun that is already outputting whether we tap into it or not (same with geothermal) differently than more limited ones like oil or uranium deposits. We'll probably change the language if we ever get into megastructure or solar-system scale engineering that blurs that distinction.
