Biofuels as in from farming? Modern farming just turns oil into crops, so turning the crops back into oil is a non-solution. The only viable current biofuels work by turn leftover waste matter into fuel - in other words, recycling.
Also, any farming done for primary energy is farming not done for food.
- graemep 2y agoNO problem, we just cut down a few more rainforests or similar to make room for more farming.
- mapt 2y agoFarming does not need to be that way. It's very amenable to electrification. Long haul aviation needs high energy density. You have heard critiques about farming that focus on very specific uses of corn and soybean under conventional American agribusiness, and while these are by no means the best biofuel feed stocks or the best harvesting methods, the low ROE is irrelevant if you are willing to feed in arbitrary quantities of cheap solar power to get precious liquid hydrocarbons out. Flying contributes only 2.5% to global carbon emissions and it is one of the applications where hydrocarbons are least replaceable - bar hydrogen. It is dramatically easier to shift over anything that doesn't have to fight gravity, so flying will likely decarbonize last.
