I've been obsessively recording my household daily electricity usage since we moved in to first home in Jan 2004. We don't own a car or use gas or wood for heating - so our electricity use is a rough indicator of how our carbon footprint is trending.

Michael Lawley's house (four person living) averages under 5 kWh/day. He uses a wood burner for heating and has a much better designed and insulated house.

I don't know whether these include industrial electricity consumption or not. It's interesting that the numbers are jump around so much. I assume different sources use different population numbers.
In 2007 we were averaging just over 14 kWh per day (8 kWh per day in summer up to 24 kWh in winter). 2008 we averaged 19.5 kWh per day - so we're heading in the wrong direction energy-wise. Although we are still well below the 8000 kWh threshold that makes us eligible for the "low user" discount.
My 2011 goal is to use less than the previous year. (Which feels like a pretty feeble goal.)
Our electricity usage includes all heating and cooking, plus the usual TV's, radio's etc. Plus an electric lawnmower and the web server that serves up this site. It does not include the weather station and it's laptop, which run off my solar PV panels.
Overseas readers may be interested to know that New Zealand's electricity supply in 2010 was 74% generated from renewables (mostly hydro* and geothermal). This means my electricity usage has a smaller carbon foot print here than it would in the USA/UK/Europe where a lot of electricity is generated from coal.
