Biomass and the environment
Biomass and biofuels made from biomass are alternative energy sources to fossil fuels—coal, petroleum, and natural gas. Burning either fossil fuels or biomass releases carbon dioxide (CO 2 ), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO 2 through photosynthesis …
