biomass

• What are biomass fuels derived from?

  Living or recently dead biological material
• Why are biomass fuels considered renewable energy sources?

  They can be replenished through natural processes
• What are the types of biomass fuels?

  1. Solid Biomass

  • Wood
  • Agricultural waste
  • Animal waste

  1. Liquid Biomass (Biofuels)

  • Bioethanol (from fermented sugars)
  • Biodiesel (from vegetable oils or animal fats)
• What is bioethanol derived from?

  Fermented sugars in crops
• What is the main component of biogas?

  Methane and CO₂
• What are the advantages of biomass fuels?

  • Renewable: Can be replenished over time
  • Carbon Neutral: Offsets emissions
  • Reduces Waste: Utilizes various waste types
  • Versatile: Used for heating, electricity, and transport
• What is a potential disadvantage of biomass fuels related to land use?

  Competes with food production
• How can biomass fuels contribute to air pollution?

  Burning releases CO₂ and CO
• What is a consequence of large-scale biomass production?

  May lead to habitat loss
• Why might biomass fuels have lower efficiency compared to fossil fuels?

  They have lower energy density (amount of energy stored)
• What is one of the carbon-neutral claims of biomass fuels?

  Plants absorb CO₂ during growth
