Flashcards

Biomass fuel effect on CO2

Burning biomass releases the same amount of CO2 as it absorbs when growing.

Fossil fuel CO2 release

Burning fossil fuels releases ancient CO2 into the atmosphere.

Biomass density vs. fossil fuels

Biomass has a lower density than fossil fuels, meaning more biomass is needed for the same energy output.
