You must have missed reading about the test flight that was done with a more sustainable jet fuel. Or maybe you missed the fact the US Navy has been experimenting with it as well.
Maybe you missed the report that came out this week that sustainables accounted for 2/3rds of new power generation added in 2016. Not a single new coal plant was added and several were converted to cleaner burning natural gas.

The fact is that sustainable power generation for transportation and homes is becoming radically more popular. Investments are up, generation is up both in metered capacity and percentage of total capacity, and costs are down. You might not like it, but sustainable is here to stay, and even industries are adopting it because it's helping their bottom line.
