Biomass is any living plant matter
Biomass energy is energy made from something
that is or once was plant matter

As a fire burns down, it gets hotter

Heat can be used to cook, boil water

Rice husk1 bowl = 1000 grains of rice
1 bowl per day x 365 days per year
= 365,000 grains of rice per year
365,000 grains of rice 36,500 grains per kg
= 10 kg per year per person
13,000,000 people in Manila x 10 kg per person = 130,000,000 kg
Rice husk mountain!

Food or animal waste ferments in
the pond, releasing methane gas
Methane is highly
flammable!!

Humans also generate lots of waste! Covered landfills capture methane like a balloon
This methane can be used to generate electricity
