How biomass is used
There are four ways to get energy from biomass, these are: burning, fermentation, bacterial decay, and conversion to liquid/gas. The method used the most is burning, and wood is the main material burned. BURNING biomass can generate steam and heat energy. BACTERIAL DECAY is when they add bacteria to make the dead plants and animals decay and give off a gas called methane. Methane is the main ingredient for natural gas which is used in our homes for stoves and furnaces. FERMENTATION is when yeast is added to biomass to produce a alcohol called ethanol. Ethanol is used to create motor oil. Conversion is when biomass is converted into liquid or gas, this happens by adding heat or chemicals to the biomass. The gas or liquid can then be burned to create electricity or energy.
Who uses biomass?
Most of the world uses biomass for atleast 1% of their electricity. America's electricity usage consists only of 4.4% biomass. Industries mainly use it for cites and not many individual people use it for electricity.
