The beleaguered UK homeowner, faced with ever-increasing bills, may be interested to see what the US Government has been recording. The graph below, taken from the US Energy Information Administration's Heating Oil and Propane Update page, shows the monthly averages of US residential heating oil prices, compared to the previous year:
To convert the American figures to UK pence per litre, simply multiply by 17.15 (assuming an exchange rate of $1.54 in the £). So, the early January price of $3.34/gallon is equivalent to 57p/L. It seems that our friends across the Atlantic have seen sizeable price increases over the 2010 winter too.

Full breakdown of residential prices since 1990
Full breakdown of wholesale prices since 1990
This appears to indicate that residential prices have risen in line with wholesale prices - a very different experience to what we suspect has been happening in the UK.
