biofuels won't work. they take too much land and are inefficient in terms of producing.
The solution: Ditch carbon based fuels as much as possible and replace it with electric transport.
I know that it's currently unviable to use electric aircraft in almost all use cases except short range drones. But then the solution to that problem is to rely less on air travel and transport and use land based alternatives.
This is about vectors and incentives. Investing in bio fuels to get a 100% replacement for fossil fuels is not going to work and it only stalls what actually needs to happen which is a radical transport system change.
If you thought habitat destruction from palm oil was bad, that would be nothing compared to coconut oil making up any significant fraction of jet fuel.
I don't think the answer is obvious. And I think many of us are blind or numb to environmental harms of oil outside of carbon exhaust and the occasional spill, simply because we've accepted it as status quo.
The issue with oil is CO2 and other green house gases and then the occasional oil spill or leak. Land area wise they don’t take up much space
Various other bio-fuel and synthesized replacements for petroleum-based jet fuel have been tried and are in development. The aviation industry is very slow to approve and adopt changes.
