The Cycle

• Biomass is collected by trucks.
• The trucks take the biomass to a power plant.
• This is then fed into a furnace where it is
  burned.
• The heat is used to boil water in the boiler, and
  the energy in the steam is used to turn turbines
  and generators.

Are Bio-fuels the solution for the future?

• Bio-fuels have some good and bad things about
  them. They are great because they are a renewable
  source of energy, but when they are burnt they
  produce a poisonous gas called methane.
