There has been plenty of talk on the Daily Source Code recently about Biodiesel, I was surprised to find that there is a supplier in Oxford. I'm thinking about giving it a try, it's not much cheaper than regular diesel but this is because of supply and demand; if you sell a lot of something it's cheaper, so I can do my bit for the cause by becoming a biodiesel user now. There is half the amount of tax on biodiesel than regular diesel, so if the production costs come down because of increased demand we'll have cheaper fuel that is better for the environment than the alternative.

In a related note, funds are running low at the moment so I'm trying to save fuel by working from home more often and traveling to the NW once a week where possible (as compared to 3-4 times!). I also tried hard to drive economically on the way home tonight and I averaged 71.6mpg over 122 miles, not bad for a big-ish car is it?
