Final answer:
Biomass energy is clean and free to harness, but can be challenging to capture and store. It includes sources such as wood, crops, manure, and food scraps. Heat energy from biomass is captured and used to generate electricity.
Step-by-step explanation:
Biomass energy is a renewable energy source that is characterized by the use of plant and animal materials to generate power. One characteristic of biomass energy is that it is clean and free to harness, but can be a challenge to capture and store. Sources of biomass include wood, crops, manure, and food scraps that are considered garbage. Heat energy from biomass is captured and then released to power steam turbines, which generate electricity.
