Bio Fuels

• What process do plants use to collect energy from sunlight?

  Photosynthesis
• How do plants store energy from sunlight?

  As chemical energy through photosynthesis
• What is the primary source of energy for plants?

  The sun
• What do plants convert water and carbon dioxide into during photosynthesis?


  Glucose
• What role do animals play in the food chain related to plants?


  Animals gain chemical energy by eating plants
• What are biofuels?


  Plant-based matter that can be burnt to release chemical energy
• Give an example of a typical biofuel.


  Firewood
• What happens to the chemical energy in firewood when it is burnt?


  It is transferred to thermal energy and released as heat
• What are most biofuels derived from?


  Waste products from other uses of plant matter
• How can waste material from carpentry be utilized?


  It can be burnt as fuel
• What is a key environmental consideration when using biofuels?


  How given sources can impact the environment
• What are two uses of burning biofuels?


  Heating homes and powering small electrical generators
• What can used cooking oil be refined into?

  Biodiesel
• Are biofuels considered renewable energy resources?


  Yes, as long as new plants are given a chance to grow
• What happens if we do not replant biofuels after use?


  We cannot replace the fuel and may damage the environment
• What is a consequence of deforestation related to biofuels?


  Increased greenhouse gases in the atmosphere
• What are the overall advantages and disadvantages of biofuels?


  Advantages:

  • Easy to source
  • Renewable
  • Carbon neutral

  
  

  Disadvantages:

  • Release less energy than fossil fuels
  • Require refining for use
  • Need replanting after use
• Why are biofuels considered carbon neutral?


  Because the carbon dioxide released is taken back in by new plants
• What is a limitation of biofuels compared to fossil fuels?


  They do not release as much energy
• What is necessary for biofuels to remain renewable?


  Replanting after use
• What are some applications of biofuels in everyday life?


  • Heating homes (e.g., fireplaces)
  • Powering small electrical generators (e.g., biodiesel generators)
• What is the website mentioned for GCSE revision resources?
