Fuels

[jashaan]

Hi,

I was going over this dot point below from the study design:
-the comparison of fossil fuels (coal, crude oil, petroleum gas, coal seam gas) and biofuels (biogas, bioethanol,
biodiesel) with reference to energy content, renewability and environmental impacts related to sourcing and
combustion

How much do we need to know about the environmental impacts etc? I read a few pages of the textbook and it's very detailed (

Thanks!
