Question

biomass energy can be a sustainable carbon - neutral source of energy. how do we use biomass for energy? we soak it in water to release heat energy. we burn it (combustion) or chemically convert it to biofuel.

Explanation:

Soaking biomass in water does not release usable heat energy for energy production. The standard methods of using biomass for energy involve direct combustion to generate heat/electricity, or chemical conversion processes (like fermentation, pyrolysis) to create biofuels such as ethanol or biodiesel, which aligns with carbon-neutral sustainable energy use.

Answer:

We burn it (combustion) or chemically convert it to biofuel.
