Which of the following is a renewable source of energy?

Biomass is renewable because plant and animal matter regrows and can be replenished continually.

Uranium is a finite mined mineral, so it is non-renewable.

Petroleum is a fossil fuel formed over millions of years and cannot be quickly replaced.

Coal is likewise a finite fossil fuel, not renewable.

Biomass stores recent solar energy captured through photosynthesis.

Burning biomass is broadly carbon-neutral if the plants are regrown.
