There's more work when it comes to growing and handling these crops, and this lifestyle in general.
more money and resources that we do not always have.
We don't always have a certain animal waste - which can slow down the process a little more if there's not enough of a certain thing. But of course referencing the pro side of things - we will always be able to produce biomass energy through things such as dead plants, etc.
I hope this helps, and you pass! Good luck, rockstar! (:
