Which describes why the sun is a renewable resource?

it very often shines, it's always there ... but it is burning fuel, the fuel is itself ... so hoiw renewable is it over billions of years ?

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
