In Germany there is a law in place that increases the price for fossil fuels each year by applying a 'CO2 tax'.
So, it was clear the diesel price would eventually hit 2.00 EUR/L and over in a matter of time.
That's why I got an old fashioned diesel engine: It could be converted to vegetable oil.
Right now, plant oil (when used as motor fuel) is taxed like any other fuel; including the CO2 tax, although vegetable oil is actually CO2 neutral.
With the price for the raw (untaxed) vegetable oil usually higher as (untaxed) fossil diesel, there was no benefit yet.
But now, at least the latter argument may have changed. And probably in near future also the CO2 tax might get put right.
There are not many vehicles left on the road that could run vegetable oil, so that wouldn't be a driver, but other appliances like heating could....
If they really want to get independent of crude oil and promote environmentally friendly energy, vegetable oil must be considered and be promoted.
Probably we should get into the rabbit hole of a vegetable oil conversion sooner than expected.
Any experience here? (I have a 3B).
