  • We can burn trees and wood to use the energy given off.
  • burning is not a good idea as it is destructive and gives off air pollution.
  • Burning wood only releases as much carbon into the atmosphere as the tree that it comes from absorbed as it grew.
  • we plant new trees to absorb roughly the same amount of carbon that burning trees will release, but this can take many years.
  • Balancing out the carbon released and carbon absorbed is known as being carbon neutral.
  •  By not burning non-renewable energy sources, such as coal or gas, or trees that are never replanted, we are trying to save on carbon emissions
  • This is a cycle that we can keep on repeating, meaning that over a long time this process can count as renewable.
  • We convert crops into liquid biofuel. 
  • biodiesel can be made from sugar cane and used to fuel cars instead of diesel from oil.
  • A type of alcohol called ethanol can be made from corn and be can also used as biofuel for vehicles.
