Biomass

Definition

Biomass refers to organic material derived from plants and animals, which can be used as a renewable energy source. It encompasses a variety of materials, including agricultural residues, wood, and even waste products, making it an important component in efforts to reduce greenhouse gas emissions and promote low-carbon development.

5 Must Know Facts For Your Next Test

1. Biomass can be converted into various forms of energy, including electricity, heat, and biofuels like ethanol and biodiesel.
2. Using biomass for energy helps reduce reliance on fossil fuels, which are major contributors to climate change due to their high carbon emissions.
3. Biomass can be sourced sustainably by managing forests and agricultural practices to ensure that biomass production does not harm ecosystems.
4. The combustion of biomass for energy can still release carbon dioxide; however, this CO2 is considered part of the natural carbon cycle since it is reabsorbed by plants during photosynthesis.
5. Innovative technologies such as anaerobic digestion allow for the conversion of organic waste into biogas, providing both a waste management solution and a renewable energy source.

Review Questions
