No need for home-work , I can tell you this, in the 70's and 80's I used to drive wagons from the Uk to the Middle East, UAE, Oman, etc I used to get 800litres of red diesel in the trailer belly tank in Dover, exported on a T3, until the vehicle was out of mainland Europe, (EEC) once we had left Austria and entered what was known then as the commie block countries, we could legally use the red diesel. I did this for about 5 years, running a Scania Truck, and had no fuel line problems whatsoever, although i did have to carry the diesel receipts and copies of the T3,s just in case the vehicle was inspected by HMCustoms, I used to fill up in Arab countries at the equivalent of 8p per gallon, which got me most of the way home, the round trip often exceeded 6000 miles, in a vehicle doing on average 11mpg, only because it wasn't possible to get a load back until reaching Bulgaria(Honey Drums for Oxford, or. Czechoslovakia, for printed goods, Comics,Magazines, etc). The vehicle fully laden would do about 9mpg.To much to write on her why.. just do a bit of home work & find out why?
How?The main reason for the high prices are the various green policies that both directly add substantially to the price, but have also reduced global production and put up the price.
It's common knowledge that 25% of Electric and Gas bills are for Green subsidies, like paying for the electricity from Solar Panels etc, there is also a premium charged on the bills to cover non-payers, the recent hike is seen by some as a last ditch attempt to get as much as possible before the Gas is banned, Shell Esso etc, are not likely to build any Petrol Stations as if people switch to EV;s obviously demand will go down, also it's hardly viable to drill new wells when it's uncertain there will be any economically viable demand.
