An Australian Parliamentary committee has recommended that petrol and diesel cars be phased out in favour of electric vehicles in a report. This is not yet law but shows that the government is serious about reducing the dependency Australia has on oil and reducing greenhouse emissions.

Not a farmer, but had a great tour of a family owned Western NY dairy farm a few years back, about 100 milk cows and enough field crops to cover most of the feed. That day they had one of their tractors running a soybean press off the PTO. The soy oil extracted was mixed 50-50 with diesel, cutting the fuel bill roughly in half. They mentioned the possibility of making bio-diesel, but for now had concluded that the 50-50 mix without further processing (except straining for particles) was a good fit for their operation.
Forgot the brand of press, but they had looked at several (making visits to other farms) and concluded that one had a much better extraction capability as well as longer service life -- not all oil presses are the same.
They also mentioned that the de-oiled soybean mash was healthier for the cows, forgot details but there is something bad for cows in plain soybeans?

I forget the exact kind, but soybeans naturally produce a number of female hormones, which are likely extracted in the process of pressing for oil. As a result the mash would be mostly the protein with dramatically reduced hormonal products in it (which would have become a contaminant in the oil instead.)
I am not sure if those products are normally extracted/filtered out from soybean oil meant for human consumption, but they wouldn't affect fuel oil/diesel much if at all compared to sulfur contamination, so press and fuel with the bonus of healthier soy mash for the cows sounds like a net win.
