Biomass is any organic matter like trees, plants, or animal waste that can be used as an energy source. Energy comes from the sun through a process called photosynthesis and is released when biomass is burned or decomposes.
How It Works
Leftover wood and crop waste from factories and farms can be burned to produce electricity.
- Wood scraps, sawdust and crop waste are collected from farms or manufacturing plants
- The waste is burned to heat water and create steam
- Steam is sent to a turbine, which spins to power a generator
- The generator creates electricity and sends to transmission lines
Waste produced by cows or other farm animals creates a gas called methane, which can be captured to produce electricity.
- Animal waste is collected in a large tank or pond with bacteria
- As bacteria decomposes the waste (i.e. methane) is released
- Methane is then burned to heat water and generate steam
- Steam turns a generator turbine to create electricity, which is sent to transmission lines
Biomass is a renewable energy source because trees and crops can always be grown
Biomass has been around since the beginning of time when man burned wood for heating and cooking
If you’ve ever been near a campfire or a fireplace, you’ve witnessed biomass energy through the burning of wood
