Hello biomass people! In this image we can see the cycle of the biomass energy. They are a forest and the humans cut it. Then lead the wood in a factory and then burn it and we have electricity. The C02 who we relased, the trees used for the photosynthesis. And we start again.
Bye!

Anna's, Hossni and Ernest.
