Biomass By the amazing Grace M, the gorgeous Caroline and Luke.

Definition An organic material made from plant and animal waste.

Advantages Will never run out We are burning Garbage which gets rid of more land fills. Biomass can be used instead of fossil fuels Biomass can provide extra income for farmers (because we also burn crops) They do not even have to be good crops because we burn them. Wood and wood waste are already a big engery in the US.

Disadvantages Stinky!!! We are also burning food which we need to live!! Biomass creates a deadly gas called Carbon Dioxide. (trees collect Carbon Dioxide which is good that is why we need trees.) Biomass crops are not around all year. - It takes more energy to create biomass than we get out of it. It could lead to global warming.

Interesting facts Biomass is only 4% of the energy we use. A man made gas out of wood. Biomass is a solid and liquid.

How it works You burn the substances and it creates a gas and lets off heat.
