Here’s an interesting British concept: fuel poverty. Defined as households that spend more than 10% of their income on fuel. I think this means electricity and natural gas, but not transportation, but it’s not clear.
Fuel poverty is obviously a function of income, fuel prices and efficiency. As prices have been rising all over, this will become a topic of greater interest, in the UK and US–especially if we have a cold winter and high heating oil prices.
BBC reports that about 3.5 million households in the UK were in fuel poverty in 2006 (not sure why there is such a data lag–it would be nice to see more recent data, with electricity prices in UK risiing). That about 15% of the 24 million households in the UK.
I wonder what the US data would show?
