Time for those that can, to think about another way of doing things . Grow you own oil !!!!! or grow your own wood !!!
It is easy to do either way , but prices for bought in stuff are not going to go down in the long term so if you are going to do it , do it now .
If you plant wood , you can go for willow , ash and hazel ( all have other uses as well , basketry, fencing etc etc). 3 or 4 acres would be what was needed . Either a boggy field for willow or maybe just extra wide hedges all the way round your holding .
Oil is more intensive as you have to process the seed once grown and harvested . Sunflower or rape seed are probably the best to go for , but I am not sure how well this type of stuff grows too far up north ?
About 1/3 of the weight of seed is oil , so 3 ton = 1 ton of oil (+ the remaining 2 ton is animal feed ie oil seed cake). You have to have some sort of processor to get the oil out and that could set you back from £500 - £1000 for a new machine , but it is a one off expense and would cope with many more tons of seed than you are likely to ever process. The hand operated ones are ok for very small amounts of oil , but for 1000 litres + forget them .
Once you have the seed and the processor , you are set up for virtually free oil thereafter .
The same with the wood. Once planted and growing the coppice will provide you with all you need for just the time it takes to cut and stack .
For those that say " but it means loads of work " and " this can happen , or that can happen " and so on , don't do it , carry on paying for it at whatever price 'they' decide you are going to have to pay ., and it IS NOT GOING TO GET CHEAPER !!!
