Biomass is also stored solar energy. When plants grow, they capture and store the sun's energy through photosynthesis.

Most of the available biomass energy is from agricultural crops, forest residues and plants. Some crops, such as woody crops, corn and grass, are specifically grown on farms for use as energy sources.
