Similar to measures of mean national income (GDP/population) or other such aggregate measures.
Note that direct consumption is often a small fraction of total consumption, and household measures of consumption of one form of energy (e.g., MWh of annual electrical use) neglect not only the shares of commercial, industrial, and governmental usage, but of other forms such as natural gas and vehicle fuel.
Who is going to tell Floridians they need to be like Britain and turn off their AC?
Finland seems high in those numbers though, maybe because its all cold?
The big thing that the article doesn't mention is that "developed" western countries outsource vast amounts of manufacturing energy usage to other countries. The UK is especially bad for this. We don't make most of our steel, aluminium, plastics or chemicals - so the many kWh required to make them isn't reported in our statistics. China does that for us.
Does anyone understand how the article arrives at these figures? I might have missed something, but these numbers seem to me as a lot. According to my energy provider my 2 person household uses about 2100kWh annually. This is in my case without gas-powered heating, and external power use (such as personal transportation, or production of bought goods).
I can understand if these more indirect uses of energy are included in the average, however it would be helpful for the discussion if these numbers were explained. It might for instance help to explain how the West can slash it's energy use five fold, as the article suggests.
