Explain why using wind, solar, and biomass energy can lead to sustainable energy use.

These are things that won't be going away. Natural gasses and fossil fuels will likely run out someday or become much harder to find. When you use these sources of energy, they won't be going away and therefore will be sustainable because we can always continue using them.

Does that make sense?

Explanation:

Because they are all clean sources of energy, that would not be destroying the planet. They are also more sustainable because unlike fossil fuels, they do not run out.
