What is a significant advantage of using biomass as an energy source?

Biomass as an energy source is considered a significant advantage primarily because it is a sustainable and renewable resource. This means that biomass can be replenished naturally over time, as it consists of organic materials such as plant matter and animal waste that can be regrown or regenerated. Utilizing biomass contributes to a closed-loop system, where the carbon dioxide released during energy production can be offset by the carbon dioxide absorbed by plants during their growth. This interplay supports a more balanced carbon cycle compared to fossil fuels, which release carbon that has been sequestered underground for millions of years.

Unlike the other options, which describe less favorable aspects of energy sources, the characteristic of sustainability and renewability highlights biomass’s potential for long-term energy use without depleting resources. This focus on sustainability aligns with global efforts to reduce reliance on finite resources and minimize environmental impacts associated with energy production.
