Since it's a 25 minute video (ugh): what's the tl;dw for why biofuels are unscalable and worse for the environment?

  Most of the worlds farmland is used to feed the worlds population and farm animals. The worlds use of fuel is many times greater in terms of calories than use of food. That means if we want to use farmland to grow fuel, we're going to need a lot more farmland. We already farm most of the land that's viable for farming.

  The energy put into the process to grow and ferment the plants or algae is high enough to outweigh the offset use of fossil fuels. It's an energy negative process. The same creator has a 15 minute video on that topic: https://www.youtube.com/watch?v=OpEB6hCpIGM https://www.youtube.com/watch?v=OpEB6hCpIGM

      I'll defer to the 15 minute video- the creator is an engineer whos credentials exceed my own, and he goes into why it's unlikely to ever become viable.
